7. Non-pressurized gases subject to special requirements (gas samples). 2.2.2.1.3 Substances and articles (except aerosols) of Class 2 are assigned to one of the following groups according to their hazardous properties, as follows: A asphyxiant; O oxidizing; F flammable; T toxic; TF toxic, flammable; TC toxic, corrosive; TO toxic, oxidizing; TFC toxic, flammable, corrosive; TOC toxic, oxidizing, corrosive. For gases and gas mixtures presenting hazardous properties associated with more than one group according to the criteria, the groups designated by letter T take precedence over all other groups. The groups designated by letter F take precedence over the groups designated by letters A or O. NOTE 1: In the UN Model Regulations, the IMDG Code and the ICAO Technical Instructions, gases are assigned to one of the following three divisions, based on the primary hazard: Division 2.1: flammable gases (corresponding to the groups designated by the capital letter F); Division 2.2: non-flammable, non-toxic gases (corresponding to the groups designated by the capital letters A or O); Division 2.3: toxic gases (corresponding to the groups designated by the capital letter T (i.e. T, TF, TC, TO, TFC and TOC). 2: Receptacles, small containing gas (UN No. 2037) shall be assigned to the groups A to TOC according to the hazard of the contents. For aerosols (UN No. 1950), see 2.2.2.1.6. 3: Corrosive gases are considered to be toxic, and are therefore assigned to the group TC, TFC or TOC. 4: Mixtures containing more than 21% oxygen by volume shall be classified as oxidizing. 2009/89. szám 2.2.2.1.4 If a mixture of Class 2 mentioned by name in Table A of Chapter 3.2 meets different criteria as mentioned in 2.2.2.1.2 and 2.2.2.1.5, this mixture shall be classified according to the criteria and assigned to an appropriate N.O.S. entry. 2.2.2.1.5 Substances and articles (except aerosols) of Class 2 which are not mentioned by name in Table A of Chapter 3.2 shall be classified under a collective entry listed in 2.2.2.3 in accordance with 2.2.2.1.2 and 2.2.2.1.3. The following criteria shall apply: Asphyxiant gases Gases which are non-oxidizing, non-flammable and non-toxic and which dilute or replace oxygen normally in the atmosphere. Flammable gases Gases which at 20 °C and a standard pressure of 101.3 kPa: (a) are ignitable when in a mixture of 13% or less by volume with air; or (b) have a flammable range with air of at least 12 percentage points regardless of the lower flammable limit. Flammability shall be determined by tests or by calculation, in accordance with methods adopted by ISO (see ISO 10156:1996). Where insufficient data are available to use these methods, tests by a comparable method recognized by the competent authority of the country of origin may be used. If the country of origin is not a COTIF Member State these methods shall be recognized by the competent authority of the first COTIF Member State reached by the consignment. Oxidizing gases Gases, which may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does. Oxidizing ability is determined either by tests or by calculation methods adopted by ISO (see ISO 10156:1996 and ISO 10156-2:2005). Toxic gases NOTE: Gases meeting the criteria for toxicity in part or completely owing to their corrosivity are to be classified as toxic. See also the criteria under the heading "Corrosive gases" for a possible subsidiary corrosivity risk. Gases which: (a) are known to be so toxic or corrosive to humans as to pose a hazard to health; or (b) are presumed to be toxic or corrosive to humans because they have a LC50 value for acute toxicity equal to or less than 5 000 ml/m³ (ppm) when tested in accordance with 2.2.61.1. In the case of gas mixtures (including vapours of substances from other classes) the following formula may be used: i i n =i T f = (mixture) Toxic LC ¦ where fi = mole fraction of the ith component substance of the mixture; Ti = toxicity index of the ith component substance of the mixture. The Ti equals the LC50 value as found in packing instruction P200 of 4.1.4.1. When no LC50 value is listed in packing instruction P200 of 4.1.4.1, a LC50 value available in scientific literature shall be used. When the LC50 value is unknown, the toxicity index is determined by using the lowest LC50 value of substances of similar physiological and chemical effects, or through testing if this is the only practical possibility. Corrosive gases Gases or gas mixtures meeting the criteria for toxicity completely owing to their corrosivity are to be classified as toxic with a subsidiary corrosivity risk. A gas mixture that is considered to be toxic due to the combined effects of corrosivity and toxicity has a subsidiary risk of corrosivity when the mixture is known by human experience to be destructive to the skin, eyes or mucous membranes or when the LC50 value of the corrosive components of the mixture is equal to or less than 5 000 ml/m3 (ppm) when the LC50 is calculated by the formula: 2009/89. szám i i n =i Tc fc = (mixture) Corrosive LC ¦ where fci = mole fraction of the ith corrosive component substance of the mixture; Tci = toxicity index of the ith corrosive component substance of the mixture. The Tci equals the LC50 value as found in packing instruction P200 of 4.1.4.1. When no LC50 value is listed in packing instruction P200 of 4.1.4.1, a LC50 value available in scientific literature shall be used. When the LC50 value is unknown the toxicity index is determined by using the lowest LC50 value of substances of similar physiological and chemical effects, or through testing if this is the only practical possibility. 2.2.2.1.6 Aerosols Aerosols (UN No. 1950) are assigned to one of the following groups according to their hazardous properties, as follows: A asphyxiant; O oxidizing; F flammable; T toxic; C corrosive; CO corrosive, oxidizing; FC flammable, corrosive; TF toxic, flammable; TC toxic, corrosive; TO toxic, oxidizing; TFC toxic, flammable, corrosive TOC toxic, oxidizing, corrosive. The classification depends on the nature of the contents of the aerosol dispenser. NOTE: Gases, which meet the definition of toxic gases according to 2.2.2.1.5 or of pyrophoric gases according to packing instruction P200 in 4.1.4.1, shall not be used as a propellant in an aerosol dispenser. Aerosols with contents meeting the criteria for packing group I for toxicity or corrosivity shall not be accepted for carriage (see also 2.2.2.2.2). The following criteria shall apply: (a) Assignment to group A shall apply when the contents do not meet the criteria for any other group according to sub-paragraphs (b) to (f) below; (b) Assignment to group O shall apply when the aerosol contains an oxidizing gas according to 2.2.2.1.5; (c) Assignment to group F shall apply if the contents include 85% by mass or more flammable components and the chemical heat of combustion is 30 kJ/g or more. It shall not apply if the contents contain 1% by mass or less flammable components and the heat of combustion is less than 20 kJ/g. Otherwise the aerosol shall be tested for flammability in accordance with the tests described in the Manual of Tests and Criteria, Part III, section 31. Extremely flammable and flammable aerosols shall be assigned to group F. NOTE: Flammable components are flammable liquids, flammable solids or flammable gases and gas mixtures as defined in Notes 1 to 3 of sub-section 31.1.3 of Part III of the Manual of Tests and Criteria. This designation does not cover pyrophoric, self-heating or water-reactive substances. The chemical heat of combustion shall be determined by one of the following methods: ASTM D 240, ISO/FDIS 13943:1999 (E/F) 86.1 to 86.3 or NFPA 30B; (d) Assignment to group T shall apply when the contents, other than the propellant of aerosol dispensers to be ejected, are classified as Class 6.1, packing groups II or III; (e) Assignment to group C shall apply when the contents, other than the propellant of aerosol dispensers to be ejected, meet the criteria for Class 8, packing groups II or III; (f) When the criteria for more than one group amongst groups O, F, T, and C are met, assignment to groups CO, FC, TF, TC TO, TFC or TOC shall apply, as relevant. 2009/89. szám 2.2.2.2 Gases not accepted for carriage 2.2.2.2.1 Chemically unstable substances of Class 2 shall not be accepted for carriage, unless the necessary steps have been taken to prevent all possibility of a dangerous reaction e.g. decomposition, dismutation or polymerisation under normal conditions during transport. To this end particular care shall be taken to ensure that receptacles and tanks do not contain any substances liable to promote these reactions. 2.2.2.2.2 The following substances and mixtures shall not be accepted for carriage: – UN No. 2186 HYDROGEN CHLORIDE, REFRIGERATED LIQUID; – UN No. 2421 NITROGEN TRIOXIDE; – UN No. 2455 METHYL NITRITE; – Refrigerated liquefied gases which cannot be assigned to classification codes 3A, 3O or 3F; – Dissolved gases which cannot be classified under UN Nos. 1001, 2073 or 3318; – Aerosols where gases which are toxic according to 2.2.2.1.5 or pyrophoric according to packing instruction P200 in 4.1.4.1 are used as propellants; – Aerosols with contents meeting the criteria for packing group I for toxicity or corrosivity (see 2.2.61 and 2.2.8); – Receptacles, small, containing gases which are very toxic (LC50 lower than 200 ppm) or pyrophoric according to packing instruction P200 in 4.1.4.1. 2.2.2.3 List of collective entries Compressed gases Classification code UN No. Name of the substance or article 1 A COMPRESSED GAS, N.O.S. 1 O COMPRESSED GAS, OXIDIZING, N.O.S. 1 F HYDROCARBON GAS MIXTURE, COMPRESSED, N.O.S.

The heading of Class 3 also covers liquid substances and molten solid substances with a flash-point of more than 60 °C and which are carried or handed over for carriage whilst heated at temperatures equal to or higher than their flash-point. These substances are assigned to UN No. 3256. The heading of Class 3 also covers liquid desensitized explosives. Liquid desensitized explosives are explosive substances which are dissolved or suspended in water or other liquid substances, to form an homogeneous liquid mixture to suppress their explosive properties. Such entries in Table A of Chapter 3.2 are UN Nos. 1204, 2059, 3064, 3343, 3357 and 3379. NOTE 1: Substances having a flash-point above 35 °C, non-toxic and non-corrosive, which do not sustain combustion according to the criteria of sub-section 32.2.5 of Part III of the Manual of Tests and Criteria, are not substances of Class 3; if, however, these substances are handed over for carriage and carried whilst heated at temperatures equal to or higher than their flashpoint, they are substances of Class 3. 2: By derogation from paragraph 2.2.3.1.1 above, diesel fuel, gasoil, heating oil (light) having a flash-point above 60 °C and not more than 100 °C shall be deemed substances of Class 3, UN No. 1202. 3: Liquids which are highly toxic on inhalation, having a flash-point below 23 °C and toxic substances, having a flash-point of 23 °C or above are substances of Class 6.1 (see 2.2.61.1). 4: Flammable liquid substances and preparations used as pesticides, which are highly toxic, toxic or slightly toxic and have a flash-point of 23 °C or above are substances of Class 6.1 (see 2.2.61.1). 2.2.3.1.2 The substances and articles of Class 3 are subdivided as follows: F Flammable liquids, without subsidiary risk: F1 Flammable liquids having a flash-point of or below 60 °C; F2 Flammable liquids having a flash-point above 60 °C which are carried or handed over for carriage at or above their flash-point (elevated temperature substances); FT Flammable liquids, toxic: FT1 Flammable liquids, toxic; FT2 Pesticides; FC Flammable liquids, corrosive; FTC Flammable liquids, toxic, corrosive; D Liquid desensitized explosives. 2.2.3.1.3 Substances and articles classified in Class 3 are listed in Table A of Chapter 3.2. Substances not mentioned by name in Table A of Chapter 3.2 shall be assigned to the relevant entry of 2.2.3.3 and the relevant packing group in accordance with the provisions of this section. Flammable liquids shall be assigned to one of the following packing groups according to the degree of danger they present for carriage: Packing group Flash-point (closed cup) Initial boiling point I -  35 °C II(a) < 23 °C > 35 °C III(a)  23 °C and  60 °C > 35 °C (a) See also 2.2.3.1.4. For a liquid with (a) subsidiary risk(s), the packing group determined in accordance with the table above and the packing group based on the severity of the subsidiary risk(s) shall be considered; the classification and packing group shall then be determined in accordance with the table of precedence of hazards in 2.1.3.10. 2009/89. szám 2.2.3.1.4 Liquid or viscous mixtures and preparations, including those containing no more than 20% nitrocellulose with a nitrogen content not exceeding 12.6% (by dry mass), shall be assigned to packing group III only if the following requirements are met: (a) the height of the separated layer of solvent is less than 3% of the total height of the sample in the solvent-separation test (see Manual of Tests and Criteria, Part III, sub-section 32.5.1); and (b) the viscosity2 and flash-point are in accordance with the following table: Flow time t in accordance with ISO 2431:1993 Kinematic viscosity (extrapolated) Q (at near-zero shear rate) mm2/s at 23 °C in s Jet diameter in mm Flash-point in °C 20 < Q d 20 < t d above 80 < Q d 60 < t d above 135 < Q d 20 < t d above 220 < Q d 32 < t d above - 1 300 < Q d 44 < t d above - 5 700 < Q 100 < t - 5 and below NOTE: Mixtures containing more than 20% but not more than 55% nitrocellulose with a nitrogen content not exceeding 12.6% by dry mass are substances assigned to UN No. 2059. Mixtures having a flash-point below 23 °C and containing: – more than 55% nitrocellulose, whatever their nitrogen content; or – not more than 55% nitrocellulose with a nitrogen content above 12.6% by dry mass, are substances of Class 1 (UN Nos. 0340 or 0342) or of Class 4.1 (UN Nos. 2555, 2556 or 2557). 2.2.3.1.5 Non-toxic, non-corrosive and non-environmentally hazardous solutions and homogeneous mixtures having a flash-point of 23 °C or above (viscous substances, such as paints or varnishes, excluding substances containing more than 20% nitrocellulose) packed in receptacles of less than 450 litres capacity, are not subject to RID if, in the solvent-separation test (see Manual of Tests and Criteria, Part III, sub-section 32.5.1), the height of the separated layer of solvent is less than 3% of the total height, and if the substances at 23 °C have, in the flow cup conforming to ISO 2431:1993 having a jet 6 mm in diameter, a flow time of: (a) not less than 60 seconds, or (b) not less than 40 seconds and contain not more than 60% of substances of Class 3. 2.2.3.1.6 If substances of Class 3, as a result of admixtures, come into categories of risk different from those to which the substances mentioned by name in Table A of Chapter 3.2 belong, these mixtures or solutions shall be assigned to the entries to which they belong on the basis of their actual degree of danger. NOTE: For the classification of solutions and mixtures (such as preparations and wastes) see also 2.1.3. 2.2.3.1.7 On the basis of the test procedures in accordance with 2.3.3.1 and 2.3.4, and the criteria set out in 2.2.3.1.1, it may also be determined whether the nature of a solution or a mixture mentioned by name or containing a substance mentioned by name is such that the solution or mixture is not subject to the provisions for this Class (see also 2.1.3). 2.2.3.2 Substances not accepted for carriage 2.2.3.2.1 Substances of Class 3 which are liable to form peroxides easily (as happens with ethers or with certain heterocyclic oxygenated substances) shall not be accepted for carriage if their peroxide content, calculated as hydrogen peroxide (H2O2), exceeds 0.3%. The peroxide content shall be determined as indicated in 2.3.3.2. 2.2.3.2.2 The chemically unstable substances of Class 3 shall not be accepted for carriage unless the necessary steps have been taken to prevent their dangerous decomposition or polymerization during carriage. To this end, it shall be ensured in particular that receptacles and tanks do not contain any substance liable to promote these reactions. 2.2.3.2.3 Liquid desensitized explosives other than those listed in Table A of Chapter 3.2 shall not be accepted for carriage as substances of Class 3. Viscosity determination: Where the substance concerned is non-Newtonian, or where a flow cup method of viscosity determination is otherwise unsuitable, a variable shear-rate viscometer shall be used to determine the dynamic viscosity coefficient of the substance, at 23 °C, at a number of shear rates. The values obtained are plotted against shear rate and then extrapolated to zero shear rate. The dynamic viscosity thus obtained, divided by the density, gives the apparent kinematic viscosity at nearzero shear rate. 2009/89. szám 2.2.3.3 List of collective entries Subsidiary risk Classification code UN Name of the substance or article No. Flammable liquids 1133 ADHESIVES containing flammable liquid 1136 COAL TAR DISTILLATES, FLAMMABLE 1139 COATING SOLUTION (includes surface treatments or coatings used for industrial or other purposes such as vehicle undercoating, drum or barrel lining) 1169 EXTRACTS, AROMATIC, LIQUID 1197 EXTRACTS, FLAVOURING, LIQUID 1210 PRINTING INK, flammable or 1210 PRINTING INK RELATED MATERIAL (including printing ink thinning or reducing compound), flammable 1263 PAINT (including paint, lacquer, enamel, stain, shellac, varnish, polish, liquid filler and liquid lacquer base) or 1263 PAINT RELATED MATERIAL (including paint thinning or reducing compound) 1266 PERFUMERY PRODUCTS with flammable solvents 1293 TINCTURES, MEDICINAL F1 1306 WOOD PRESERVATIVES, LIQUID 1866 RESIN SOLUTION, flammable 1999 TARS, LIQUID, including road asphalt and oils, bitumen and cut backs 3065 ALCOHOLIC BEVERAGES 3269 POLYESTER RESIN KITS 1224 KETONES, LIQUID, N.O.S. 1268 PETROLEUM DISTILLATES, N.O.S. or 1268 PETROLEUM PRODUCTS, N.O.S. without 1987 ALCOHOLS, N.O.S. subsidiary 1989 ALDEHYDES, N.O.S. risk 2319 TERPENE HYDROCARBONS, N.O.S.

The following are assigned to Class 4.1: – readily flammable solid substances and articles (see paragraphs 2.2.41.1.3 to 2.2.41.1.8); – self-reactive solids or liquids (see paragraphs 2.2.41.1.9 to 2.2.41.1.16); – solid desensitized explosives (see 2.2.41.1.18); – substances related to self-reactive substances (see 2.2.41.1.19). 2.2.41.1.2 The substances and articles of Class 4.1 are subdivided as follows: F Flammable solids, without subsidiary risk: F1 Organic; F2 Organic, molten; F3 Inorganic; FO Flammable solids, oxidizing; FT Flammable solids, toxic: FT1 Organic, toxic; FT2 Inorganic, toxic; FC Flammable solids, corrosive: FC1 Organic, corrosive; FC2 Inorganic, corrosive; D Solid desensitized explosives without subsidiary risk; DT Solid desensitized explosives, toxic; SR Self-reactive substances: SR1 Not requiring temperature control; SR2 Requiring temperature control (not accepted for carriage by rail). Flammable solids Definition and properties 2.2.41.1.3 Flammable solids are readily combustible solids and solids which may cause fire through friction. Readily combustible solids are powdered, granular, or pasty substances which are dangerous if they can be easily ignited by brief contact with an ignition source, such as a burning match, and if the flame spreads rapidly. The danger may come not only from the fire but also from toxic combustion products. Metal powders are especially dangerous because of the difficulty of extinguishing a fire since normal extinguishing agents such as carbon dioxide or water can increase the hazard. Classification 2.2.41.1.4 Substances and articles classified as flammable solids of Class 4.1 are listed in Table A of Chapter 3.2. The assignment of organic substances and articles not mentioned by name in Table A of Chapter 3.2 to the relevant entry of 2.2.41.3 in accordance with the provisions of Chapter 2.1 can be based on experience or on the results of the test procedures in accordance with Part III, sub-section 33.2.1 of the Manual of Tests and Criteria. The assignment of inorganic substances not mentioned by name shall be based on the results of the test procedures in accordance with Part III, sub-section 33.2.1 of the Manual of Tests and Criteria; experience shall also be taken into account when it leads to a more stringent assignment. 2.2.41.1.5 When substances not mentioned by name are assigned to one of the entries listed in 2.2.41.3 on the basis of the test procedures in accordance with the Manual of Tests and Criteria, Part III, sub-section 33.2.1, the following criteria apply: (a) With the exception of metal powders or powders of metal alloys, powdery, granular or pasty substances shall be classified as readily flammable substances of Class 4.1 if they can be easily ignited by brief contact with an ignition source (e.g. a burning match), or if, in the event of ignition, the flame spreads rapidly, the burning time is less than 45 seconds for a measured distance of 100 mm or the rate of burning is greater than 2.2 mm/s. 2009/89. szám (b) Metal powders or powders of metal alloys shall be assigned to Class 4.1 if they can be ignited by a flame and the reaction spreads over the whole length of the sample in 10 minutes or less. Solids which may cause fire through friction shall be classified in Class 4.1 by analogy with existing entries (e.g. matches) or in accordance with any appropriate special provision. 2.2.41.1.6 On the basis of the test procedure in accordance with the Manual of Tests and Criteria, Part III, Section 33.2.1 and the criteria set out in 2.2.41.1.4 and 2.2.41.1.5, it may also be determined whether the nature of a substance mentioned by name is such that the substance is not subject to the provisions for this Class. 2.2.41.1.7 If substances of Class 4.1, as a result of admixtures, come into different categories of risk from those to which the substances mentioned by name in Table A of Chapter 3.2 belong, these mixtures shall be assigned to the entries to which they belong on the basis of their actual degree of danger. NOTE: For the classification of solutions and mixtures (such as preparations and wastes), see also 2.1.3. Assignment of packing groups 2.2.41.1.8 Flammable solids classified under the various entries in Table A of Chapter 3.2 shall be assigned to packing groups II or III on the basis of test procedures of the Manual of Tests and Criteria, Part III, sub-section 33.2.1, in accordance with the following criteria: (a) Readily flammable solids which, when tested, have a burning time of less than 45 seconds over a measured distance of 100 mm shall be assigned to: Packing group II: if the flame passes the wetted zone; Packing group III: if the wetted zone stops the flame for at least four minutes; (b) Metal powders or powders of metal alloys shall be assigned to: Packing group II: if, when tested, the reaction spreads over the whole length of the sample in five minutes or less; Packing group III: if, when tested, the reaction spreads over the whole length of the sample in more than five minutes. For solids which may cause fire through friction, the packing group shall be assigned by analogy with existing entries or in accordance with any special provision. Self-reactive substances Definitions 2.2.41.1.9 For the purposes of RID, self-reactive substances are thermally unstable substances liable to undergo a strongly exothermic decomposition even without participation of oxygen (air). Substances are not considered to be self-reactive substances of Class 4.1, if: (a) they are explosives according to the criteria of Class 1; (b) they are oxidizing substances according to the classification procedure for Class 5.1 (see 2.2.51.1) except that mixtures of oxidizing substances which contain 5% or more of combustible organic substances shall be subjected to the classification procedure defined in Note 2; (c) they are organic peroxides according to the criteria of Class 5.2 (see 2.2.52.1); (d) their heat of decomposition is less than 300 J/g; or (e) their self-accelerating decomposition temperature (SADT) (see Note 3 below) is greater than 75 °C for a 50 kg package. NOTE 1: The heat of decomposition can be determined using any internationally recognised method e.g. differential scanning calorimetry and adiabatic calorimetry. 2: Mixtures of oxidizing substances meeting the criteria of Class 5.1 which contain 5% or more of combustible organic substances, which do not meet the criteria mentioned in (a), (c), (d) or (e) above, shall be subjected to the self-reactive substance classification procedure. A mixture showing the properties of a self-reactive substance, type B to F, shall be classified as a self-reactive substance of Class 4.1. A mixture showing the properties of a self-reactive substance, type G, according to the principle given in sub-section 20.4.3 (g) of Part II of the Manual of Tests and Criteria shall be considered for classification as a substance of Class 5.1 (see 2.2.51.1). 3: The self-accelerating decomposition temperature (SADT) is the lowest temperature at which self-accelerating decomposition may occur with a substance in the packaging as used during carriage. Requirements for the determination of the SADT are given in the Manual of Tests and Criteria, Part II, Chapter 20 and section 28.4. 4: Any substance which shows the properties of a self-reactive substance shall be classified as such, even if this substance gives a positive test result according to 2.2.42.1.5 for inclusion in Class 4.2. 2009/89. szám Properties 2.2.41.1.10 The decomposition of self-reactive substances can be initiated by heat, contact with catalytic impurities (e.g. acids, heavy-metal compounds, bases), friction or impact. The rate of decomposition increases with temperature and varies with the substance. Decomposition, particularly if no ignition occurs, may result in the evolution of toxic gases or vapours. For certain self-reactive substances, the temperature shall be controlled. Some self-reactive substances may decompose explosively, particularly if confined. This characteristic may be modified by the addition of diluents or by the use of appropriate packagings. Certain selfreactive substances burn vigorously. Self-reactive substances are, for example, some compounds of the types listed below: aliphatic azo compounds (-C-N=N-C-); organic azides (-C-N3); diazonium salts (-CN2 + Z–); N-nitroso compounds (-N-N=O); and aromatic sulphohydrazides (-SO2-NH-NH2). This list is not exhaustive and substances with other reactive groups and some mixtures of substances may have similar properties. Classification 2.2.41.1.11 Self-reactive substances are classified into seven types according to the degree of danger they present. The types of self-reactive substances range from type A, which is not accepted for carriage in the packaging in which it is tested, to type G, which is not subject to the provisions for self-reactive substances of Class 4.1. The classification of types B to F is directly related to the maximum quantity allowed in one packaging. The principles to be applied for classification as well as the applicable classification procedures, test methods and criteria and an example of a suitable test report are given in Part II of the Manual of Tests and Criteria. 2.2.41.1.12 Self-reactive substances which have already been classified and are already permitted for carriage in packagings are listed in 2.2.41.4, those already permitted for carriage in IBCs are listed in 4.1.4.2, packing instruction IBC520 and those already permitted for carriage in tanks according to Chapter 4.2 are listed in 4.2.5.2, portable tank instruction T23. Each permitted substance listed is assigned to a generic entry of Table A of Chapter 3.2 (UN Nos. 3221 to 3240) and appropriate subsidiary risks and remarks providing relevant transport information are given. The collective entries specify: – self-reactive substances types B to F, see 2.2.41.1.11 above; – physical state (liquid/solid). The classification of the self-reactive substances listed in 2.2.41.4 is based on the technically pure substance (except where a concentration of less than 100% is specified). 2.2.41.1.13 Classification of self-reactive substances not listed in 2.2.41.4, 4.1.4.2, packing instruction IBC520 or 4.2.5.2, portable tank instruction T23 and assignment to a collective entry shall be made by the competent authority of the country of origin on the basis of a test report. The statement of approval shall contain the classification and the relevant conditions of carriage. If the country of origin is not a COTIF Member State, the classification and the conditions of carriage shall be recognized by the competent authority of the first COTIF Member State reached by the consignment. 2.2.41.1.14 Activators, such as zinc compounds, may be added to some self-reactive substances to change their reactivity. Depending on both the type and the concentration of the activator, this may result in a decrease in thermal stability and a change in explosive properties. If either of these properties is altered, the new formulation shall be assessed in accordance with the classification procedure. 2.2.41.1.15 Samples of self-reactive substances or formulations of self-reactive substances not listed in 2.2.41.4, for which a complete set of test results is not available and which are to be carried for further testing or evaluation, shall be assigned to one of the appropriate entries for self-reactive substances type C provided the following conditions are met: – the available data indicate that the sample would be no more dangerous than self-reactive substances type B; – the sample is packaged in accordance with packing method OP2 and the quantity per wagon is limited to 10 kg; Samples requiring temperature control shall not be accepted for carriage by rail. 2009/89. szám Desensitization 2.2.41.1.16 In order to ensure safety during carriage, self-reactive substances are in many cases desensitized by use of a diluent. Where a percentage of a substance is stipulated, this refers to the percentage by mass, rounded to the nearest whole number. If a diluent is used, the self-reactive substance shall be tested with the diluent present in the concentration and form used in carriage. Diluents which may allow a self-reactive substance to concentrate to a dangerous extent in the event of leakage from a packaging shall not be used. Any diluent shall be compatible with the self-reactive substance. In this regard, compatible diluents are those solids or liquids which have no detrimental influence on the thermal stability and hazard type of the self-reactive substance. 2.2.41.1.17 (Reserved) Solid desensitized explosives 2.2.41.1.18 Solid desensitized explosives are substances which are wetted with water or alcohols or are diluted with other substances to suppress their explosive properties. Such entries in Table A of Chapter 3.2 are: UN Nos. 1310, 1320, 1321, 1322, 1336, 1337, 1344, 1347, 1348, 1349, 1354, 1355, 1356, 1357, 1517, 1571, 2555, 2556, 2557, 2852, 2907, 3317, 3319, 3344, 3364, 3365, 3366, 3367, 3368, 3369, 3370, 3376, 3380 and 3474. Substances related to self-reactive substances 2.2.41.1.19 Substances that: (a) have been provisionally accepted into Class 1 according to Test Series 1 and 2 but exempted from Class 1 by Test Series 6; (b) are not self-reactive substances of Class 4.1; and (c) are not substances of Classes 5.1 or 5.2 are also assigned to Class 4.1. UN Nos. 2956, 3241, 3242 and 3251 are such entries. 2.2.41.2 Substances not accepted for carriage 2.2.41.2.1 The chemically unstable substances of Class 4.1 shall not be accepted for carriage unless the necessary steps have been taken to prevent their dangerous decomposition or polymerization during carriage. To this end, it shall in particular be ensured that receptacles and tanks do not contain any substance liable to promote these reactions. 2.2.41.2.2 Flammable solids, oxidizing, assigned to UN No. 3097 shall not be accepted for carriage unless they meet the requirements for Class 1 (see also 2.1.3.7). 2.2.41.2.3 The following substances shall not be accepted for carriage: – Self-reactive substances of type A (see Manual of Tests and Criteria, Part II, paragraph 20.4.2 (a)); – Phosphorus sulphides which are not free from yellow and white phosphorus; – Solid densitized explosives other than those listed in Table A of Chapter 3.2; – Inorganic flammable substances in the molten form other than UN No. 2448 SULPHUR, MOLTEN.
