POSITION (EU) No 5/2011 OF THE COUNCIL AT FIRST READING

with a view to the adoption of a Regulation of the European Parliament and of the Council on textile fibre names and related labelling and marking of fibre composition of textile products and repealing Council Directive 73/44/EEC, Directive 96/73/EC of the European Parliament and of the Council and Directive 2008/121/EC of the European Parliament and of the Council

Adopted by the Council on 6 December 2010

(Text with EEA relevance)

2011/C 50 E/01

THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty on the Functioning of the European Union, and in particular Article 114 thereof,

Having regard to the proposal from the European Commission,

Having regard to the opinion of the European Economic and Social Committee (1),

Acting in accordance with the ordinary legislative procedure (2),

Whereas:

Council Directive 73/44/EEC of 26 February 1973 on the approximation of the laws of the Member States relating to the quantitative analysis of ternary fibre mixtures (3) , Directive 96/73/EC of the European Parliament and of the Council of 16 December 1996 on certain methods for the quantitative analysis of binary textile fibre mixtures (4) and Directive 2008/121/EC of the European Parliament and of the Council of 14 January 2009 on textile names (5) have been amended several times. Since further amendments are to be made, those acts should be replaced by a single legal instrument, in the interest of clarity.

The legal acts of the Union on textile fibre names and related labelling and marking of fibre composition of textile products are very technical in their content, with detailed provisions that need to be adapted regularly. In order to avoid the need for Member States to transpose the technical amendments into national legislation and thus reduce the administrative burden for national authorities and in order to allow for a faster adoption of new textile fibre names to be used simultaneously throughout the Union, a regulation seems to be the most appropriate legal instrument to carry out the legislative simplification.

In order to eliminate potential obstacles to the proper functioning of the internal market caused by Member States’ diverging provisions with regard to textile fibre names and related labelling and marking of fibre composition of textile products, it is necessary to harmonise the names of textile fibres and the indications appearing on labels, markings and documents which accompany textile products at the various stages of their production, processing and distribution.

This Regulation lays down harmonised provisions with regard to certain aspects of textile labelling and marking, in particular textile fibre names. Other labelling and marking may exist, provided that it does not cover the same scope as this Regulation and that it is compatible with the Treaties.

It is appropriate to lay down rules enabling manufacturers to ask for the inclusion of a new textile fibre name in the Annexes to this Regulation.

Provision should also be made in respect of certain products which are not made exclusively of textile materials but have a textile content which constitutes an essential part of the product or to which attention is specifically drawn by the economic operator.

The tolerance in respect of ‘extraneous fibres’, which are not to be stated on the labels and markings, should apply both to pure products and to mixtures.

Labelling or marking of the fibre composition should be compulsory to ensure correct and uniform information is made available to all consumers in the Union. However, this Regulation should not prevent economic operators from indicating, in addition, the presence of small quantities of fibres requiring particular attention to keep the original quality of the textile product. Where it is technically difficult to specify the fibre composition of a textile product at the time of its manufacture, it should be possible to state, on the label or marking, only those fibres which are known at the time of manufacture provided that they account for a certain percentage of the finished product.

In order to avoid differences in practice among the Member States, it is necessary to lay down the exact methods of labelling or marking for certain textile products consisting of two or more components, and also to specify the components of textile products that need not be taken into account for the purposes of labelling, marking and analysis.

Textile products subject only to the requirements of inclusive labelling, and those sold by the metre or in cut lengths, should be made available on the market in such a way that the consumer can fully acquaint himself with the information affixed to the overall packaging or the roll.

The use of textile fibre names or descriptions of fibre compositions which enjoy particular prestige among users and consumers should be made subject to certain conditions. Furthermore, in order to provide information to users and consumers, it is appropriate that the textile fibre names are related to the characteristics of the fibre.

The market surveillance in Member States of products covered by this Regulation is subject to Regulation (EC) No 765/2008 of the European Parliament and of the Council of 9 July 2008 setting out the requirements for accreditation and market surveillance relating to the marketing of products (6) and Directive 2001/95/EC of the European Parliament and of the Council of 3 December 2001 on general product safety (7) .

It is necessary to lay down methods for the sampling and analysis of textile products in order to exclude any possibility of objections to the methods used. The methods used for official tests carried out in the Member States to determine the fibre composition of textile products composed of binary and ternary fibre mixtures should be uniform, as regards both the pre-treatment of the sample and its quantitative analysis. It is appropriate that the methods set out to that end in this Regulation be turned into harmonised standards. Therefore, the Commission should manage the transition from the current system, which is based on the methods set out in this Regulation, to a harmonised standard-based system. The use of uniform methods of analysis of textile products composed of binary and ternary fibre mixtures will facilitate the free movement of those products, and thereby improve the functioning of the internal market.

In the case of binary textile fibre mixtures for which there is no uniform method of analysis at Union level, the laboratory responsible for the test should be allowed to determine the composition of such mixtures, indicating in the analysis report the result obtained, the method used and its degree of accuracy.

This Regulation should set out the agreed allowances to be applied to the anhydrous mass of each fibre during the determination by analysis of the fibre content of textile products, and should give two different agreed allowances for calculating the composition of carded or combed fibres containing wool and/or animal hair. Since it cannot always be established whether a product is carded or combed, and consequently inconsistent results can arise from the application of the tolerances during checks on the conformity of textile products carried out in the Union, the laboratories carrying out those checks should be authorised to apply a single agreed allowance in doubtful cases.

Rules should be laid down in respect of products exempt from the general labelling and marking requirements set out in this Regulation, in particular with respect to disposable products or products for which only inclusive labelling is required.

It is appropriate to establish a procedure for the inclusion of new textile fibre names in the Annexes to this Regulation. This Regulation should thus set out requirements regarding applications by manufacturers or other persons acting on their behalf for new textile fibre names to be added to those Annexes.

The Commission should be empowered to adopt delegated acts in accordance with Article 290 of the Treaty on the Functioning of the European Union concerning the adoption of technical criteria and procedural rules for the authorisation of higher tolerances, the amendment of Annexes II, IV, V, VI, VII, VIII and IX in order to adapt them to technical progress and the amendment of Annex I in order to include new textile fibre names in the list set out in that Annex. It is of particular importance that the Commission carry out appropriate consultations during its preparatory work, including at expert level.

Since the objective of this Regulation, namely the adoption of uniform rules for the use of textile fibre names and related labelling and marking of fibre composition of textile products, cannot be sufficiently achieved by the Member States and can therefore, by reason of its scale, be better achieved at Union level, the Union may adopt measures, in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty on European Union. In accordance with the principle of proportionality, as set out in that Article, this Regulation does not go beyond what is necessary in order to achieve that objective.

HAVE ADOPTED THIS REGULATION:

the name of the fibre which accounts for at least 85 % of the total weight immediately preceded or followed by the words ‘85 % minimum’;

2. A textile product composed of two or more fibres, none of which accounting for as much as 85 % of the total weight, shall be labelled or marked with at least the name and percentage by weight of the fibres with the highest and next highest percentage by weight of the product, immediately followed by the names of the other constituent fibres in descending order of the percentage by weight, with or without an indication of their percentage by weight.

3. Without prejudice to paragraph 2, fibres which separately account for less than 10 % of the total weight of a product may be collectively designated by the term ‘other fibres’, immediately preceded or followed by the total percentage by weight.

Where the name of a fibre which accounts for less than 10 % of the total weight of a product is specified, the full percentage composition of that product shall be given.

4. Products having a pure cotton warp and a pure flax weft, in which the percentage of flax accounts for at least 40 % of the total weight of the unsized fabric may be given the name ‘cotton linen union’ which must be accompanied by the composition specification ‘pure cotton warp — pure flax (or linen) weft’.

5. Without prejudice to Article 5(1), for textile products the composition of which is hard to state at the time of their manufacture, the term ‘mixed fibres’ or the term ‘unspecified textile composition’ may be used on the label or marking.

Article 10

Decorative fibres and fibres with antistatic effect

1. Visible, isolable fibres which are purely decorative and do not exceed 7 % of the weight of the finished product do not have to be taken into account in the fibre compositions provided for in Articles 7 and 9.

2. Metallic fibres and other fibres which are incorporated in order to obtain an antistatic effect and which do not exceed 2 % of the weight of the finished product do not have to be taken into account in the fibre compositions provided for in Articles 7 and 9.

3. In the case of the products referred to in Article 9(4), the percentages provided for in paragraphs 1 and 2 of this Article shall be calculated on the weight of the warp and that of the weft separately.

Article 11

Multi-component textile products

1. Any textile product containing two or more textile components which have different textile fibre contents shall bear a label or marking stating the textile fibre content of each component.

2. The labelling or marking referred to in paragraph 1 shall not be compulsory for textile components when the following two conditions are fulfilled:

those components are not main linings; and

those components represent less than 30 % of the total weight of the textile product.

3. Where two or more textile products have the same fibre content and normally form a single unit, they may bear only one label or marking.

Article 12

Labelling and marking of textile products listed in Annex IV

The fibre composition of textile products listed in Annex IV shall be indicated in accordance with the labelling and marking provisions set out in that Annex.

Article 13

Labels and markings

1. Textile products shall be labelled or marked to give an indication of their fibre composition whenever they are made available on the market.

The labelling and marking of textile products shall be durable, easily legible, visible and accessible and, in the case of a label, securely attached.

2. Without prejudice to paragraph 1, labels or markings may be replaced or supplemented by accompanying commercial documents when the products are being supplied to economic operators within the supply chain, or when they are delivered in performance of an order placed by any contracting authority as defined in Article 1 of Directive 2004/18/EC of the European Parliament and of the Council of 31 March 2004 on the coordination of procedures for the award of public works contracts, public supply contracts and public service contracts (8).

Article 14

Obligation to supply the label or marking

1. When placing a textile product on the market, the manufacturer shall ensure the supply of the label or marking and the accuracy of the information contained therein. If the manufacturer is not established in the Union, the importer shall ensure the supply of the label or marking and the accuracy of the information contained therein.

2. A distributor shall be considered a manufacturer for the purposes of this Regulation where he places a product on the market under his name or trademark, attaches the label himself or modifies the content of the label.

3. When making a textile product available on the market, the distributor shall ensure that textile products bear the appropriate labelling or marking prescribed by this Regulation.

4. The economic operators referred to in paragraphs 1, 2 and 3 shall ensure that any information supplied when textile products are made available on the market cannot be confused with the textile fibre names and the descriptions of fibre compositions, as laid down by this Regulation.

Article 15

The use of textile fibre names and fibre composition descriptions

1. When making a textile product available on the market, the textile fibre composition descriptions referred to in Articles 5, 7, 8 and 9 shall be indicated in catalogues and trade literature, on packaging, labels and markings in a manner that is easily legible, visible, clear and in uniform print or font. This information shall be clearly visible to the consumer before the purchase, including in cases where the purchase is made by electronic means.

2. Trade marks or the name of the undertaking may be given immediately before or after textile fibre composition descriptions referred to in Articles 5, 7, 8 and 9.

However, where a trade mark or a name of an undertaking contains, on its own or as a root or as an adjective, one of the textile fibre names listed in Annex I or a name liable to be confused therewith, such trade mark or name shall be given immediately before or after the textile fibre composition descriptions referred to in Articles 5, 7, 8 and 9.

Other information shall be always displayed separately.

3. The labelling or marking shall be provided in the official language or languages of the Member State on the territory of which the textile products are made available to the consumer, unless the Member State concerned provides otherwise.

In the case of bobbins, reels, skeins, balls or other small quantities of sewing, mending and embroidery yarns, the first subparagraph shall apply to the inclusive labelling referred to in Article 16(3). Whenever these products are individually sold, they may be labelled or marked in any of the official languages of the institutions of the Union, provided they are also inclusively labelled.

Article 16

Derogations

1. The rules laid down in Articles 11, 13, 14 and 15 shall be subject to the derogations provided for in paragraphs 2, 3 and 4 of this Article.

2. The indication of textile fibre names or fibre composition on the labels and markings of textile products listed in Annex V is not required.

However, where a trade mark or name of an undertaking contains, on its own or as a root or as an adjective, one of the names listed in Annex I or a name liable to be confused therewith, Articles 11, 13, 14 and 15 shall apply.

3. Where textile products listed in Annex VI are of the same type and fibre composition, they may be made available on the market together with an inclusive labelling.

4. The fibre composition of textile products sold by the metre may be shown on the length or roll made available on the market.

5. The textile products referred to in paragraphs 3 and 4 shall be made available on the market in such a way that the fibre composition of those products is made known to each purchaser in the supply chain, including the consumer.

CHAPTER 3

Market surveillance

Article 17

Market surveillance checks

Market surveillance authorities shall carry out checks on the conformity of the fibre composition of textile products with the supplied information related to the fibre composition of those products in accordance with this Regulation.

Article 18

Determination of fibre composition

1. For the purpose of determining the fibre composition of textile products, the checks referred to in Article 17 shall be carried out in accordance with the methods set out in Annex VIII or with the harmonised standards to be introduced in that Annex.

2. In the determination of fibre compositions set out in Articles 7, 8 and 9, the items listed in Annex VII shall not be taken into account.

3. The fibre compositions set out in Articles 7, 8 and 9 shall be determined by applying to the anhydrous mass of each fibre the appropriate agreed allowance laid down in Annex IX, after having removed the items set out in Annex VII.

4. Any laboratory responsible for the testing of textile mixtures for which there is no uniform method of analysis at Union level shall determine the fibre composition of such mixtures, indicating in the analysis report the result obtained, the method used and its degree of accuracy.

Article 19

Tolerances

1. For the purposes of establishing the fibre composition of textile products, the tolerances laid down in paragraphs 2, 3 and 4 shall apply.

2. Without prejudice to Article 8(3), the presence of extraneous fibres in the fibre composition to be provided in accordance with Article 9 does not need to be indicated if the percentage of those fibres does not reach the following values:

2 % of the total weight of the textile product, provided this quantity is justified as being technically unavoidable in good manufacturing practice and is not added as a matter of routine; or

5 % of the total weight in the case of textile products which have undergone a carding process, provided this quantity is justified as being technically unavoidable in good manufacturing practice and is not added as a matter of routine.

3. A manufacturing tolerance of 3 % shall be permitted between the stated fibre composition to be provided in accordance with Article 9 and the percentages obtained from analysis carried out in accordance with Article 18, in relation to the total weight of fibres shown on the label or marking. Such tolerance shall also apply to the following:

fibres which are listed with no indication of their percentage in accordance with Article 9(2);

the percentage of wool referred to in point (b) of Article 8(2).

For the purposes of the analysis, the tolerances shall be calculated separately. The total weight to be taken into account in calculating the tolerance referred to in this paragraph shall be that of the fibres of the finished product less the weight of any extraneous fibres found when applying the tolerance referred to in paragraph 2 of this Article.

4. The cumulative application of the tolerances referred to in paragraphs 2 and 3 shall be permitted only if any extraneous fibres found by analysis, when applying the tolerance referred to in paragraph 2, prove to be of the same chemical type as one or more of the fibres shown on the label or marking.

5. In the case of particular textile products for which the manufacturing process requires tolerances higher than those laid down in paragraphs 2 and 3, the Commission may authorise higher tolerances.

Prior to placing the textile product on the market, the manufacturer shall submit a request for authorisation by the Commission providing sufficient reasons for and evidence of the exceptional manufacturing circumstances. The authorisation may only be granted in exceptional cases and where adequate justification is provided by the manufacturer.

If appropriate, the Commission shall adopt, by means of delegated acts in accordance with Article 21 and subject to the conditions laid down in Articles 22 and 23, technical criteria and procedural rules for the application of this paragraph.

ANNEX VIII

Methods for the quantitative analysis of binary and ternary textile fibre mixtures

(referred to in Article 18(1))

CHAPTER 1

I. Preparation of laboratory test samples and test specimens to determine the fibre composition of textile products

1. FIELD OF APPLICATION

This Chapter gives procedures for obtaining laboratory test samples of a suitable size for pre-treatment for quantitative analysis (i.e. of a mass not exceeding 100 g) from laboratory bulk samples, and for selecting test specimens from the laboratory test samples that have been pre-treated to remove non-fibrous matter (1).

2. DEFINITIONS

2.1. Bulk source

The quantity of material which is assessed on the basis of one series of test results. This may comprise, for example, all the material in one delivery of cloth; all the cloth woven from a particular beam; a consignment of yarn, a bale or a group of bales of raw fibre.

2.2. Laboratory bulk sample

The portion of the bulk source taken to be representative of the whole, and which is available to the laboratory. The size and nature of the laboratory bulk sample shall be sufficient to adequately overcome the variability of the bulk source and to facilitate ease of handling in the laboratory (2).

2.3. Laboratory test sample

That portion of the laboratory bulk sample that is subjected to pre-treatment to remove non-fibrous matter, and from which test specimens are taken. The size and nature of the laboratory test sample shall be sufficient to overcome adequately the variability of the laboratory bulk sample (3).

2.4. Test specimen

The portion of material required to give an individual test result, and selected from the laboratory test sample.

3. PRINCIPLE

The laboratory test sample is selected so that it is representative of the laboratory bulk sample.

The test specimens are taken from the laboratory test sample in such a way that each of them is representative of the laboratory test sample.

4. SAMPLING FROM LOOSE FIBRES

4.1. Unorientated fibres

Obtain the laboratory test sample by selecting tufts at random from the laboratory bulk sample. Mix thoroughly the whole of the laboratory test sample by means of a laboratory carder (4). Subject the web or mixture, including loose fibres and fibres adhering to the equipment used for mixing, to pre-treatment. Then select test specimens, in proportion to the respective masses, from the web or mixture, from the loose fibres and from the fibres adhering to the equipment.

If the card web remains intact after pre-treatment, select the test specimens in the manner described in 4.2. If the card web is disturbed by the pre-treatment, select each test specimen by removing at random at least 16 small tufts of suitable and approximately equal size and then combine them.

4.2. Orientated fibres (cards, webs, slivers, rovings)

From randomly selected parts of the laboratory bulk sample cut not less than 10 cross-sections each of mass approximately 1 g. Subject the laboratory test sample so formed to the pre-treatment. Recombine the cross-sections by laying them side by side and obtain the test specimen by cutting through them so as to take a portion of each of the 10 lengths.

5. SAMPLING YARN

5.1. Yarn in packages or in banks

Sample all the packages in the bulk laboratory sample.

Withdraw the appropriate continuous equal lengths from each package either by winding skeins of the same number of turns on a wrap-reel (5), or by some other means. Unite the lengths side by side either as a single skein or as a tow to form the laboratory test sample, ensuring that there are equal lengths from each package in the skein or tow.

Subject the laboratory test sample to the pre-treatment.

Take test specimens from the laboratory test sample by cutting a bunch of threads of equal length from the skein or tow, taking care to see that the bunch contains all the threads in the sample.

If the tex of the yarn is t and the number of packages selected from the laboratory bulk sample is n, then to obtain a test sample of 10 g, the length of yarn to be withdrawn from each package is 106/nt cm.

If nt is high, i.e. more than 2 000, wind a heavier skein and cut it across in two places to make a tow of suitable mass. The ends of any sample in the form of a tow shall be securely tied before pre-treatment and test specimens taken from a place remote from the tie bands.

5.2. Yarn on warp

Take the laboratory test sample by cutting a length from the end of the warp, not less than 20 cm long and comprising all the yarns in the warp except the selvedge yarns, which are rejected. Tie the bunch of threads together near one end. If the sample is too large for pre-treatment as a whole divide it into two or more portions, each tied together for pre-treatment, and reunite the portions after each has been pre-treated separately. Take a test specimen by cutting a suitable length from the laboratory test sample from the end remote from the tie band, and comprising all the threads in the warp. For warp of N threads of tex t, the length of a specimen of mass 1 g is 105/Nt cm.

6. SAMPLING FABRIC

6.1. From a laboratory bulk sample consisting of a single cutting representative of the cloth

Cut a diagonal strip from one corner to the other and remove the selvedges. This strip is the laboratory test sample. To obtain a laboratory test sample of x g, the strip area shall be x104/G cm2, where G is the mass of the cloth in g/m2.

Subject the laboratory test sample to the pre-treatment and then cut the strip transversely into four equal lengths and superimpose them. Take test specimens from any part of the layered material by cutting through all the layers so that each specimen contains an equal length of each layer.

If the fabric has a woven design, make the width of the laboratory test sample, measured parallel to the warp direction, not less than one warp repeat of the design. If, with this condition satisfied, the laboratory test sample is too large to be treated as a whole, cut it into equal parts, pre-treat them separately, and superimpose these parts before selection of the test specimen, taking care that corresponding parts of the design do not coincide.

6.2. From a laboratory bulk sample consisting of several cuttings

Treat each cutting as described in 6.1, and give each result separately.

7. SAMPLING MADE-UP AND FINISHED PRODUCTS

The bulk laboratory sample is normally a complete made-up or finished product or representative fraction of one.

Where appropriate determine the percentage of the various parts of the product not having the same fibre content, in order to check compliance with Article 11.

Select a laboratory test sample representative of the part of the made-up or finished product, whose composition must be shown by the label. If the product has several labels, select laboratory test samples representative of each part corresponding to a given label.

If the product whose composition is to be determined is not uniform, it may be necessary to select laboratory test samples from each of the parts of the product and to determine the relative proportions of the various parts in relation to the whole product in question.

Then calculate the percentages taking into account the relative proportions of the sampled parts.

Subject the laboratory test samples to the pre-treatment.

Then select test specimens representative of the pre-treated laboratory test samples.

II. Introduction to the methods for the quantitative analysis of textile fibre mixtures

Methods for the quantitative analysis of fibre mixtures are based on two main processes, the manual separation and the chemical separation of fibres.

The method of manual separation shall be used whenever possible since it generally gives more accurate results than the chemical method. It can be used for all textiles whose component fibres do not form an intimate mixture, as for example in the case of yarns composed of several elements each of which is made up of only one type of fibre, or fabrics in which the fibre of the warp is of a different kind to that of the weft, or knitted fabrics capable of being unravelled made up of yarns of different types.

In general, the methods of chemical quantitative analysis are based on the selective solution of the individual components. After the removal of a component the insoluble residue is weighed, and the proportion of the soluble component is calculated from the loss in mass. This first part of the Annex gives the information common to the analyses by this method of all fibre mixtures dealt with in the Annex, whatever their composition. It shall thus be used in conjunction with the succeeding individual sections of the Annex, which contain the detailed procedures applicable to particular fibre mixtures. Occasionally, an analysis is based on a principle other than selective solution; in such cases full details are given in the appropriate section.

Mixtures of fibres during processing and, to a lesser extent, finished textiles may contain non-fibrous matter, such as fats, waxes or dressings, or water-soluble matter, either occurring naturally or added to facilitate processing. Non-fibrous matter must be removed before analysis. For this reason a method for removing oils, fats, waxes and water-soluble matter is also given.

In addition, textiles may contain resins or other matter added to confer special properties. Such matter, including dyestuffs in exceptional cases, may interfere with the action of the reagent on the soluble component and/or it may be partially or completely removed by the reagent. This type of added matter may thus cause errors and shall be removed before the sample is analysed. If it is impossible to remove such added matter the methods for quantitative chemical analysis given in this Annex are no longer applicable.

Dye in dyed fabrics is considered to be an integral part of the fibre and is not removed.

Analyses are conducted on the basis of dry mass and a procedure is given for determining dry mass.

The result is obtained by applying to the dry mass of each fibre the agreed allowances listed in Annex IX.

Before proceeding with any analysis, all the fibres present in the mixture shall have been identified. In some methods, the insoluble component of a mixture may be partially dissolved in the reagent used to dissolve the soluble component(s).

Where possible, reagents have been chosen that have little or no effect on the insoluble fibres. If loss in mass is known to occur during the analysis, the result shall be corrected; correction factors for this purpose are given. These factors have been determined in several laboratories by treating, with the appropriate reagent as specified in the method of analysis, fibres cleaned by the pre-treatment.

These correction factors apply only to undegraded fibres and different correction factors may be necessary if the fibres have been degraded before or during processing. The procedures given apply to single determinations.

At least two determinations on separate test specimens shall be made, both in the case of manual separation and in the case of chemical separation.

For confirmation, unless technically impossible, it is recommended to use alternative procedures whereby the constituent that was the residue in the standard method is dissolved out first.

CHAPTER 2

Methods for quantitative analysis of certain binary textile fibre mixtures

I. General information common to the methods given for the quantitative chemical analysis of textile fibre mixtures

I.1. FIELD OF APPLICATION

The field of application for each method specifies to which fibres the method is applicable.

I.2. PRINCIPLE

After the identification of the components of a mixture, the non-fibrous material is removed by suitable pre-treatment and then one of the components, usually by selective solution (6). The insoluble residue is weighed and the proportion of soluble component calculated from the loss in mass. Except where this presents technical difficulties, it is preferable to dissolve the fibre present in the greater proportion, thus obtaining the fibre present in the smaller proportion as residue.

I.3. MATERIALS AND EQUIPMENT

I.3.1. Apparatus

I.3.1.1. Filter crucibles and weighing bottles large enough to contain such crucibles, or any other apparatus giving identical results.

I.3.1.2. Vacuum flask.

I.3.1.3. Desiccator containing self-indicating silica gel.

I.3.1.4. Ventilated oven for drying specimens at 105 ± 3 °C.

I.3.1.5. Analytical balance, accurate to 0,0002 g.

I.3.1.6. Soxhlet extractor or other apparatus giving identical results.

I.3.2. Reagents

I.3.2.1. Light petroleum, redistilled, boiling range 40 to 60 °C.

I.3.2.2. Other reagents are specified in the appropriate sections of each method.

I.3.2.3. Distilled or deionised water.

I.3.2.4. Acetone.

I.3.2.5. Orthophosphoric acid.

I.3.2.6. Urea.

I.3.2.7. Sodium bicarbonate.

All reagents used shall be chemically pure.

I.4. CONDITIONING AND TESTING ATMOSPHERE

Because dry masses are determined, it is unnecessary to condition the specimen or to conduct analyses in a conditioned atmosphere.

I.5. LABORATORY TEST SAMPLE

Take a laboratory test sample that is representative of the laboratory bulk sample and sufficient to provide all the specimens, each of at least 1 g, that are required.

I.6. PRE-TREATMENT OF LABORATORY TEST SAMPLE (7)

Where a substance not to be taken into account in the percentage calculations (see Article 18) is present, it shall first be removed by a suitable method that does not affect any of the fibre constituents.

For this purpose, non-fibrous matter which can be extracted with light petroleum and water is removed by treating the laboratory test sample in a Soxhlet extractor with light petroleum for 1 hour at a minimum rate of six cycles per hour. Allow the light petroleum to evaporate from the sample, which is then extracted by direct treatment consisting in soaking the laboratory test sample in water at room temperature for 1 hour and then soaking it in water at 65 ± 5 °C for a further hour, agitating the liquor from time to time. Use a liquor-laboratory test sample ratio of 100:1. Remove the excess water from the sample by squeezing, suction or centrifuging and then allow the sample to become air-dry.

In the case of elastolefin or fibre mixtures containing elastolefin and other fibres (wool, animal hair, silk, cotton, flax (or linen) true hemp, jute, abaca, alfa, coir, broom, ramie, sisal, cupro, modal, protein, viscose, acrylic, polyamide or nylon, polyester, elastomultiester) the procedure just described shall be slightly modified, in that light petroleum ether shall be replaced by acetone.

In the case of binary fibre mixtures containing elastolefin and acetate the following procedure shall apply as pre-treatment. Extract the laboratory test sample for 10 minutes at 80 °C with a solution containing 25 g/l of 50 % orthophosphoric acid and 50 g/l of urea. Use a liquor-laboratory test sample ratio of 100:1. Wash laboratory test sample in water, then drain and wash it in a 0,1 % sodium bicarbonate solution, finally wash it carefully in water.

Where non-fibrous matter cannot be extracted with light petroleum and water, it shall be removed by substituting for the water method described above a suitable method that does not substantially alter any of the fibre constituents. However, for some unbleached, natural vegetable fibres (e.g. jute, coir) it is to be noted that normal pre-treatment with light petroleum and water does not remove all the natural non-fibrous substances; nevertheless additional pre-treatment is not applied unless the sample contains finishes insoluble in both light petroleum and water.

Analysis reports shall include full details of the methods of pre-treatment used.

I.7. TEST PROCEDURE

I.7.1. General instructions

I.7.1.1. Drying

Conduct all drying operations for not less than 4 hours and not more than 16 hours at 105 ± 3 °C in a ventilated oven with the oven door closed throughout. If the drying period is less than 14 hours, the specimen must be weighed to check that its mass has become constant. The mass may be considered to have become constant if, after a further drying period of 60 minutes, its variation is less than 0,05 %.

Avoid handling crucibles and weighing bottles, specimens or residues with bare hands during the drying, cooling and weighing operations.

Dry specimens in a weighing bottle with its cover beside it. After drying, stopper the weighing bottle before removing it from the oven, and transfer it quickly to the desiccator.

Dry the filter crucible in a weighing bottle with its cover beside it in the oven. After drying, close the weighing bottle and transfer it quickly to the desiccator.

Where apparatus other than a filter crucible is used, drying operations in the oven shall be conducted in such a way as to enable the dry mass of the fibres to be determined without loss.

I.7.1.2. Cooling

Conduct all cooling operations in the desiccator the latter placed beside the balance, until complete cooling of the weighing bottles is attained, and in any case for not less than 2 hours.

I.7.1.3. Weighing

After cooling, complete the weighing of the weighing bottle within 2 minutes of its removal from the desiccator. Weigh to an accuracy of 0,0002 g.

I.7.2. Procedure

Take from the pre-treated laboratory test sample a test specimen weighing at least 1 g. Cut yarn or cloth into lengths of about 10 mm, dissected as much as possible. Dry the specimen in a weighing bottle, cool it in the desiccator and weigh it. Transfer the specimen to the glass vessel specified in the appropriate section of the relevant Union method, reweigh the weighing bottle immediately and obtain the dry mass of the specimen by difference. Complete the test as specified in the appropriate section of the applicable method. Examine the residue microscopically to check that the treatment has in fact completely removed the soluble fibre.

I.8. CALCULATION AND EXPRESSION OF RESULTS

Express the mass of the insoluble component as a percentage of the total mass of fibre in the mixture. The percentage of soluble component is obtained by difference. Calculate the results on the basis of clean, dry mass, adjusted by (a) the agreed allowances and (b) the correction factors necessary to take account of loss of matter during pre-treatment and analysis. Calculations shall be made by applying the formula given in I.8.2.

I.8.1. Calculation of percentage of insoluble component on clean, dry mass basis, disregarding loss of fibre mass during pre-treatment:

where

P1% is the percentage of clean, dry insoluble component, m is the dry mass of the test specimen after pre-treatment, r is the dry mass of the residue, d is the correction factor for loss in mass of the insoluble component in the reagent during the analysis. Suitable values for ‘d’ are given in the relevant section of each method.

Of course, these values for ‘d’ are the normal values applicable to chemically undegraded fibres.

I.8.2. Calculation of percentage of insoluble component on clean, dry mass basis, with adjustment by conventional factors and, where appropriate, correction factors for loss of mass during pre-treatment:

where

P1A% is the percentage of insoluble component adjusted by agreed allowances and for loss in mass during pre-treatment, P1 is the percentage of clean dry insoluble component as calculated from the formula shown in I.8.1, a1 is the agreed allowance for the insoluble component (see Annex IX), a2 is the agreed allowance for the soluble component (see Annex IX), b1 is the percentage loss of insoluble component caused by pre-treatment, b2 is the percentage loss of soluble component caused by pre-treatment.

The percentage of the second component is P2A % = 100 – P1A %.

Where a special pre-treatment has been used, the values of b1 and b2 shall be determined, if possible, by submitting each of the pure fibre constituents to the pre-treatment applied in the analysis. Pure fibres are those free from all non-fibrous material except that which they normally contain (either naturally or because of the manufacturing process), in the state (unbleached, bleached) in which they are found in the material to be analysed.

Where no clean separate constituent fibres used in the manufacture of the material to be analysed are available, average values of b1 and b2 as obtained from tests performed on clean fibres similar to those in the mixture under examination, shall be used.

If normal pre-treatment by extraction with light petroleum and water is applied, correction factors b1 and b2 may generally be ignored, except in the case of unbleached cotton, unbleached flax (or linen) and unbleached hemp, where the loss due to the pre-treatment is conventionally taken as 4 %, and in the case of polypropylene, where it is taken as 1 %.

In the case of other fibres, losses due to the pre-treatment are conventionally disregarded in calculations.

II. Method of quantitative analysis by manual separation

II.1. FIELD OF APPLICATION

This method is applicable to textile fibres of all types provided they do not form an intimate mixture and that it is possible to separate them by hand.

II.2. PRINCIPLE

After identification of the constituents of the textile, the non-fibrous material is removed by suitable pre-treatment and then the fibres are separated by hand, dried and weighed in order to calculate the proportion of each fibre in the mixture.

II.3. APPARATUS

II.3.1. Weighing bottle or any other apparatus giving identical results.

II.3.2. Desiccator containing self-indicating silica gel.

II.3.3. Ventilated oven for drying specimens at 105 ± 3 °C.

II.3.4. Analytical balance, accurate to 0,0002 g.

II.3.5. Soxhlet extractor, or other apparatus giving an identical result.

II.3.6. Needle.

II.3.7. Twist tester or similar apparatus.

II.4. REAGENTS

II.4.1. Light petroleum, redistilled, boiling range 40 to 60 °C.

II.4.2. Distilled or deionised water.

II.4.3. Acetone.

II.4.4. Orthophosphoric acid.

II.4.5. Urea.

II.4.6. Sodium bicarbonate.

All reagents used shall be chemically pure.

II.5. CONDITIONING AND TESTING ATMOSPHERE

See I.4.

II.6. LABORATORY TEST SAMPLE

See I.5.

II.7. PRE-TREATMENT OF LABORATORY TEST SAMPLE

See I.6.

II.8. PROCEDURE

II.8.1. Analysis of yarn

Select from the pre-treatment laboratory test sample a specimen of mass not less than 1 g. For a very fine yarn, the analysis may be made on a minimum length of 30 m, whatever its mass.

Cut the yarn into pieces of a suitable length and separate the fibre types by means of a needle and, if necessary, a twist tester. The fibre types so obtained are placed in pre-weighed weighing bottles and dried at 105 ± 3 °C until a constant mass is obtained, as described in I.7.1 and I.7.2.

II.8.2. Analysis of cloth

Select from the pre-treated laboratory test sample, well away from all selvedges, a specimen of mass not less than 1 g, with edges carefully trimmed to avoid fraying and running parallel with weft or warp yarns, or in the case of knitted fabrics in the line of wales and courses. Separate the different fibre types, collect them in pre-weighed weighing bottles and proceed as described in II.8.1.

II.9. CALCULATION AND EXPRESSION OF RESULTS

Express the mass of each fibre constituent as a percentage of the total mass of the fibres in the mixture. Calculate the results on the basis of clean, dry mass, adjusted by (a) the agreed allowances and (b) the correction factors necessary to take account of loss of matter during pre-treatment.

II.9.1. Calculation of percentage masses of clean, dry fibre, disregarding loss of fibre mass during pre-treatment:

P1% is the percentage of the first clean, dry component, m1 is the clean, dry mass of the first component, m2 is the clean, dry mass of the second component.

II.9.2. For calculation of the percentage of each component with adjustment by agreed allowances and, where appropriate, by correction factors for loss of matter during pre-treatment, see I.8.2.

III.1. Precision of the methods

The precision indicated in individual methods relates to the reproducibility.

The reproducibility refers to the reliability, i.e. the closeness of agreement between experimental values obtained by operators in different laboratories or at different times using the same method and obtaining individual results on specimens of an identical consistent mixture.

The reproducibility is expressed by confidence limits of the results for a confidence level of 95 %.

Therefore, the difference between two results in a series of analyses made in different laboratories would, given a normal and correct application of the method to an identical and consistent mixture, exceed the confidence limit only in five cases out of a 100.

III.2. Test report

III.2.1. State that the analysis was conducted in accordance with this method.

III.2.2. Give details of any special pre-treatment (see I.6).

III.2.3. Give the individual results and the arithmetic mean, each to an accuracy of 0,1.

METHOD No 1

ACETATE AND CERTAIN OTHER FIBRES

(Acetone method)

1. FIELD OF APPLICATION

This method is applicable, after removal of non-fibrous matter, to binary fibre mixtures of:

1. acetate (19); with

2. wool (1), animal hair (2 and 3), silk (4), cotton (5), flax (or linen) (7), true hemp (8), jute (9), abaca (10), alfa (11), coir (12), broom (13), ramie (14), sisal (15), cupro (21), modal (22), protein (23), viscose (25), acrylic (26), polyamide or nylon (30), polyester (35) elastomultiester (45), elastolefin (46) and melamine (47).

In no circumstances is the method applicable to acetate fibres which have been deacetylated on the surface.

2. PRINCIPLE

The acetate is dissolved out from a known dry mass of the mixture, with acetone. The residue is collected, washed, dried and weighed; its mass, corrected if necessary, is expressed as a percentage of the dry mass of the mixture. The percentage of dry acetate is found by difference.

3. APPARATUS AND REAGENTS (additional to those specified in the general instructions)

3.1. Apparatus

Glass-stoppered conical flasks of at least 200 ml capacity.

3.2. Reagent

Acetone.

4. TEST PROCEDURE

Follow the procedure described in the general instructions and proceed as follows:

To the test specimen contained in a glass-stoppered conical flask of at least 200 ml capacity, add 100 ml of acetone per gram of test specimen, shake the flask, stand it for 30 minutes at room temperature, stirring from time to time, and then decant the liquid through the weighed filter crucible.

Repeat the treatment twice more (making three extractions in all), but for periods of 15 minutes only, so that the total time of treatment in acetone is 1 hour. Transfer the residue to the filter crucible. Wash the residue in the filter crucible with acetone and drain with suction. Refill the crucible with acetone and allow to drain under gravity.

Finally, drain the crucible with suction, dry the crucible and residue, and cool and weigh them.

5. CALCULATION AND EXPRESSION OF RESULTS

Calculate the results as described in the general instructions. The value of ‘d’ is 1,00, except for melamine, for which ‘d’ = 1,01.

6. PRECISION

On a homogeneous mixture of textile materials, the confidence limits of results obtained by this method are not greater than ± 1 for a confidence level of 95 %.

METHOD No 2

CERTAIN PROTEIN FIBRES AND CERTAIN OTHER FIBRES

(Method using hypochlorite)

1. FIELD OF APPLICATION

This method is applicable, after removal of non-fibrous matter, to binary fibre mixtures of:

1. certain protein fibres, namely: wool (1), animal hair (2 and 3), silk (4), protein (23); with

2. cotton (5), cupro (21), modal (22), viscose (25), acrylic (26), chlorofibres (27), polyamide or nylon (30), polyester (35), polypropylene (37), elastane (43), glass fibre (44), elastomultiester (45), elastolefin (46) and melamine (47).

If different protein fibres are present, the method gives the total of their amounts but not their individual quantities.

2. PRINCIPLE

The protein fibre is dissolved out from a known dry mass of the mixture, with a hypochlorite solution. The residue is collected, washed, dried and weighed; its mass, corrected if necessary, is expressed as a percentage of the dry mass of the mixture. The percentage of dry protein fibre is found by difference.

Either lithium hypochlorite or sodium hypochlorite can be used for the preparation of the hypochlorite solution.

Lithium hypochlorite is recommended in cases involving a small number of analyses or for analyses conducted at fairly lengthy intervals. This is because the percentage of hypochlorite in solid lithium hypochlorite — unlike that in sodium hypochlorite — is virtually constant. If the percentage of hypochlorite is known, hypochlorite content need not be checked iodometrically for each analysis, since a constant weighed portion of lithium hypochlorite can be employed.

3. APPARATUS AND REAGENTS (other than those specified in the general instructions)

3.1. Apparatus

(i) Erlenmeyer flask with ground-glass stopper, 250 ml.

(ii) Thermostat, adjustable to 20 (± 2) °C.

3.2. Reagents

(i) Hypochlorite reagent

(a) Lithium hypochlorite solution

This consists of a freshly prepared solution containing 35 (± 2) g/l of active chlorine (approximately 1 M), to which 5 (± 0,5) g/l of previously dissolved sodium hydroxide is added. To prepare, dissolve 100 grams of lithium hypochlorite containing 35 % active chlorine (or 115 grams containing 30 % active chlorine) in approximately 700 ml of distilled water, add 5 grams of sodium hydroxide dissolved in approximately 200 ml of distilled water and make up to 1 litre with distilled water. The solution which has been freshly prepared need not be checked iodometrically.

(b) Sodium hypochlorite solution

This consists of a freshly prepared solution containing 35 (± 2) g/l of active chlorine (approximately 1 M) to which 5 (± 0,5) g/l of previously dissolved sodium hydroxide is added.

Check the active chlorine content of the solution iodometrically before each analysis.

(ii) Acetic acid, dilute solution

Dilute 5 ml of glacial acetic acid to 1 litre with water.

4. TEST PROCEDURE

Follow the procedure described in the general instructions and proceed as follows: mix approximately 1 gram of the test specimen with approximately 100 ml of the hypochlorite solution (lithium or sodium hypochlorite) in the 250 ml flask and agitate thoroughly in order to wet out the test specimen.

Then heat the flask for 40 minutes in a thermostat at 20 °C and agitate continuously, or at least at regular intervals. Since the dissolution of the wool proceeds exothermically, the reaction heat of this method must be distributed and removed. Otherwise, considerable errors may be caused by the incipient dissolution of the non-soluble fibres.

After 40 minutes, filter the flask contents through a weighed glass-filter crucible and transfer any residual fibres into the filter crucible by rinsing the flask with a little hypochlorite reagent. Drain the crucible with suction and wash the residue successively with water, dilute acetic acid, and finally water, draining the crucible with suction after each addition. Do not apply suction until each washing liquor has drained under gravity.

Finally, drain the crucible with suction, dry the crucible with the residue, and cool and weigh them.

5. CALCULATION AND EXPRESSION OF RESULTS

Calculate the results as described in the general instructions. The value of ‘d’ is 1,00, except for cotton, viscose, modal and melamine for which ‘d’ = 1,01, and unbleached cotton, for which ‘d’ = 1,03.

6. PRECISION

Keep the flask and its contents at a constant temperature of 40 °C for 2 hours and a half, shaking the flask at hourly intervals.

Filter the contents of the flask through the weighed filter crucible and with the help of the reagent transfer to the crucible any fibres remaining in the flask. Rinse with 20 ml of reagent pre-heated to 40 °C.

Wash crucible and residue thoroughly with water at 40 °C. Rinse the fibrous residue in approximately 100 ml of cold ammonia solution (3.2.ii) ensuring that this residue remains wholly immersed in the solution for 10 minutes (8); then rinse thoroughly with cold water.
