ISO 8501-1 Pictorial Standards of Cleanliness
ISO 8501-1 is a pictorial standard relating to surface cleanliness, amongst other methods, though abrasive
blasting. The original condition of steel surfaces prior to blasting are depicted in various stages of
corrosion as follows:
Grade A Grade B
Grade C Grade D
Grade A Steel surface largely covered with adhering mill scale but little, if any rust
Grade B Steel surface which has begun to rust and from which the mill scale has begun to flake
Grade C Steel surface on which the mill scale has ruted away or from which it can be scraped, but with slight
pitting visible under normal vision.
Grade D Steel surface on which the mill scale has rusted away and on which general pitting is visible under
normal vision
Standard notation usually, but not always, includes the original condition of steel before blasting i.e. “B Sa3”.
Pictorial standards of cleanliness (Sa1, Sa2, Sa2.5 and Sa3) are depicted overleaf.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 23277 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 121, Welding (as EN 1289:1998 and its Amd.1:2002 and Amd.2:2003), and was adopted, under a
special “fast-track procedure”, by Technical Committee ISO/TC 44, Welding and allied processes,
Subcommittee SC 5, Testing and inspection of welds, in parallel with its approval by the ISO member bodies.
This document constitutes a consolidated version.
Requests for official interpretations of any aspect of this International Standard should be directed to the
Secretariat of ISO/TC 44/SC 5 via your national standards body. A complete listing of these bodies can be
found at http://www.iso.org.

Non-destructive testing of welds — Penetrant testing
of welds — Acceptance levels
1 Scope
This International Standard specifies acceptance levels for indications from surface breaking imperfections in
metallic welds detected by penetrant testing.
The acceptance levels are primarily intended for use during manufacture examination, but where appropriate
they can be used for in-service inspection.
The acceptance levels in this International Standard are based on detection capabilities that can be expected
when using techniques specified in ISO 3452 and parameters recommended in Annex A. The acceptance
levels can be related to welding standards, application standards, specifications or codes. Such a relationship
is shown in ISO 17635 for ISO 5817 and ISO 10042.

3.2
non-linear indication

4 Testing parameters
4.1 General
Many parameters, either individually or in combination, will affect the shape and size of a penetrant indication
produced by a weld imperfection.
The following items are significant factors that will affect the shape and size of indications.
4.2 Sensitivity
Penetrant materials are classified in accordance with ISO 3452-2, including a sensitivity level which relates to
the ability to detect small imperfections. Generally higher sensitivity materials should be used for the detection
of small imperfections.
4.3 Surface condition
Surface condition is directly related to the minimum detectable imperfection size. Best results are normally
achieved when inspecting smooth surfaces. Surface roughness or irregularities (e. g. undercut, spatter) can
cause high background and non-relevant indications resulting in a low probability of detection for small
imperfections.
4.4 Process and technique
Penetrant systems and techniques should be selected according to the test surface condition. In some cases
the choice will have a direct effect on the limits of reliable detection, for example the removal of excess
penetrant by swab cleaning on rough surfaces is not recommended when seeking small imperfections.
Guidance on these matters is given in Annex A and in ISO 3452.
5 Acceptance levels
5.1 General
The width of the test surface shall include the weld metal and the adjacent parent metal up to a distance of
10 mm on each side.
Indications produced by penetrant testing do not usually display the same size and shape characteristics as
the imperfection causing that indication. For the purposes of this standard, it is the size of the indication which
should be assessed against the values shown in Table 1.
Acceptance levels prescribed for linear indications are those corresponding to the evaluation level. Indications
lower than this shall not be taken into account. Normally, acceptable indications shall not be recorded.
Local grinding may be used to improve the classification of all or part of a test surface when it is required to
work to a higher detection limit than that recommended by the existing weld surface condition in Table A.1.
Acceptance levels for welds in metallic materials are given in Table 1.

a Acceptance levels 2 and 3 may be specified with a suffix "X" which denotes that all linear indications detected shall be evaluated to
level 1. However the probability of detection of indications smaller than those denoted by the original acceptance level can be low.
5.2 Evaluation of indications
Initial evaluation shall be carried out as described in ISO 3452 and final evaluation of indication size shall be
carried out after a designated minimum development time has elapsed, and before the indication has
degenerated such that it no longer represents the causing imperfection.
5.3 Grouped indications
Any adjacent indications separated by less than the major dimension of the smaller shall be assessed as a
single, continuous indication.
Grouped indications shall be evaluated in accordance with an application standard.
5.4 Removal of imperfections
Where the product specification permits, local grinding may be used to reduce or remove imperfections which
are the cause of unacceptable indications. All such areas shall be re-tested and evaluated with the same
penetrant system and technique.

a The weld cap and parent material offer smooth clean surfaces with negligible undercut, rippling and spatter. The surface finish is
typical of welds made by automatic TIG-welding, submerged arc welding (fully mechanized) and manual metal arc welding process
using iron powder electrodes.
b The weld cap and parent material offer reasonably smooth surfaces with minimal undercut, rippling and spatter. The surface finish
is typical of welds made by manual metal arc welding vertical downwards and MAG welding using argon rich gas for the capping runs.
c The weld cap and parent material are in the as-welded condition. The surface finish is typical of welds produced by the manual
metal arc and MAG welding processes in any position.

Introduction
Theperformanceof protectivecoatings of paintandrelated products appliedto steelis significantlyaffected bythe
state of the steel surface immediately prior to painting. The principal factors that are known to influence this
performanceare:
a) thepresenceofrustandmillscale;
b) thepresenceofsurfacecontaminants,includingsalts,dust,oilsandgreases;
c) thesurfaceprofile.
International Standards ISO8501, ISO8502 and ISO8503 have been prepared to provide methods of assessing
these factors, while ISO8504 provides guidance on the preparation methods that are available for cleaning steel
substrates,indicatingthecapabilitiesofeachinattainingspecifiedlevelsofcleanliness.
These International Standards do not contain recommendations for the protective coating system to be applied to
the steel surface. Neither do they contain recommendations for the surface quality requirements for specific
situations even though surface qualitycan have a direct influence on the choice of protective coating to be applied
and on its performance. Such recommendations are found in other documents such as national standards and

3 General
The primaryobjective of surface preparation is to ensure the removal of deleterious matter and to obtain a surface
that permits satisfactory adhesion of the priming paint to the steel. It will also assist in reducing the amounts of
contaminantsthatinitiatecorrosion.

This particularly applies to maintenance of an already coated structure. The age of the structure and its location,
thequalityoftheprevioussurface,theperformanceoftheexistingcoatingsystemandtheextentofbreakdown,the
typeandseverityofpreviousandfuturecorrosionenvironments,andtheintendednewcoatingsystem allinfluence
theamountofpreparationrequired.
When selecting a surface preparation method, it is necessary to consider the preparation grade required to give a
level of surface cleanliness and, if required, a surface profile (roughness) appropriate to the coating system to be
appliedtothesteelsurface.Sincethecostofsurfacepreparationis usuallyinproportiontothelevel of cleanliness,
a preparation grade appropriate to the purpose and type of coating system or a coating system appropriate to the
preparationgradewhichcanbeachievedshouldbechosen.
Personnel carrying out surface preparation work shall have suitable equipment and sufficient technical knowledge
of the processes involved to enable them to carry out the work in accordance with the required specification. All
relevant health and safety regulations shall be observed. It is important that the surfaces to be treated are readily
accessibleandsufficientlyilluminated.Allsurfacepreparationworkshallbeproperlysupervisedandinspected.

4 Condition of the surface to be prepared
4.1 Assessment of the surfacecondition
As the cost of surface preparation is significantly influenced by the condition of the surface to be prepared,
information as given in a) or b) below should be available before particular surface preparation methods and
preparation grades are specified. The rust grade assessed in accordance with ISO8501-1 will determine which
representativephotographicexample(s)is(are)tobeusedinaccordancewithISO8501-1orISO8501-2.

4.2 Influence of on-site environmental conditions
In order to hold down the cost of surface preparation and because of possible severe contamination by corrosion-
stimulatingsubstancesthataredifficulttoremove,storageofunprotectedsteelinindustrialormarineenvironments
should be avoided. As far as possible, surface preparation should take place when rust grade A or B (or rust
gradeC for manual preparation) as defined by ISO8501-1 is present, followed by application of a suitable primer
assoonaspossible.
No surface preparation work using dry or moisture-injection (see ISO8504-2) blast-cleaning methods or other dry
surface preparation methods should be carried out on site during rainfall or other precipitation. To minimize
condensationonthesurface,the temperatureof the surfacebeingpreparedshould be higher (usuallyat least3°C
higher) than the dew point of the surrounding air. If the work has to be continued even under unfavourable
conditions, it is essential to take special precautions such as working under a cover, enclosing in a tent, warming
thesurfaceand/ordryingtheair(seeISO8502-4).
Surface preparation work in areas where there is a fire or explosion hazard requires special precautions (for
examplelow-spark,electrical-groundingorflame-freeprocedures).
4.3 Removal of contaminants
Oil, grease, dirt andsimilar contaminants shall be removed prior to surface preparation using the selected method.

Introduction
The performance of protective coatings of paint and related products applied to steel is
significantly affected by the state of the steel surface immediately prior to painting. The
principal factors that are known to influence this performance are:
a) the presence of rust and mill scale;
b) the presence of surface contaminants, including salts, dust, oils and greases;
c) the surface profile.
International Standards IS0 8501, IS0 8502 and IS0 8503 have been prepared to provide
methods of assessing these factors, while IS0 8504 provides guidance on the preparation
methods that are available for cleaning steel substrates, indicating the capabilities of each in
attaining specified levels of cleanliness.
These International Standards do not contain recommendations for the protective coating system
to be applied to the steel surface. Neither do they contain recornendations for the surface
quality requirements for specific situations even though surface quality can have a direct
influence on the choice of protective coating to be applied and on its performance. Such
recommendations are found in other documents such as national standards and codes of
practice. It will be necessary for the users of these International Standards to ensure that the
qualities specified are:
-c ompatible and appropriate both for the environmental conditions to which the steel
will be exposed and for the protective coating system to be used;
- within the capability of the cleaning procedure specified.
The four Intemational Standards referred to above deal with the following aspects of preparation
of steel substrates:
IS0 8501 Visual assessment of surface cleanliness;
IS0 8502 Testsf or the assessment of sulface cleanliness;
IS0 8503 Su flace roughness characteristics of blast-cleaned steel substrates;
IS0 8504 Surface preparation methods.
Each of these International Standards is in turn divided into separate parts.

This part of IS0 8502 describes a field method for the assessment of the total amount of water-
soluble salts, the salts being regarded as forming one single contaminant. The more aggressive
contaminants causing corrosion and blistering (the ionic species) can easily be dissolved off and
determined rapidly by this method. Consequently, the less aggressive and not so easily dissolved
minor part of contaminant will remain un-assessed. For additional information on the test
method, its potential and its limitations, see BRESLE, Å., Conductometric determination of
salts on steel surfaces, MP (Materials Perf¿mzance),J une 1995, Vol. 34, No. 6, pp. 35-37,
NACE International, Houston TX, USA.
Rusty steel substrates, particularly those of rust grades C or D (see IS0 8501-i), even when
blast-cleaned to preparation grade Sa3 (see ISO8501-1 and ISO8501-2), may still be
contaminated by water-soluble salts and corrosion products. These compounds are almost
colourless and are localized at the lowest point of the rust pits. If they are not removed prior to
painting, chemical reactions can result in blister formation and accumulations of rust that
destroy the adhesion between the substrate and the applied protective coating.

Part 9:
Field method for the conductometric determination of water-soluble
salts
1 Scope
This part of IS0 8502 describes a field method for the assessment of the total surface density of
various water-soluble salts (mostly chlorides and sulfates) on steel surfaces before and/or after
surface preparation.
The individual surface densities of chlorides, sulfates, etc., cannot be determined by this
method.
This method assesses ionic contaminants only. These represent the greater part of the
contamination.
2 Normative references

All standards are subject to revision, and parties to agreement based on this part of IS0 8502 are
encouraged to investigate the possibility of applying the most recent editions of the standards
indicated below. Members of IEC and IS0 maintain registers of currently valid International
Standards.

IS0 8502-6: 1995, Preparation of steel substrates before application of paints and related
products - Tests for the assessment of su$ace cleanliness - Part 6: Extraction of soluble
contaminants for analysis - The Bresle method.
3 Principle
The salts on the given area of the steel surface are dissolved by the Bresle method (see
IS0 8502-6), using water as solvent. The conductivity of the solution thus obtained is measured.
Finally, the total surface density of the salts in this area is calculated by a simple but sufficiently
accurate equation.

4 Solvent
Water of at least grade 3 purity in accordance with IS0 3696.
NOTE - Usually, distilled or de-ionized water of conductivity less than 0,5 mS/m (5 @km) meets
this requirement.
5 Apparatus and materials
5.1 Conductometer, with temperature compensation and sufficient range, e.g. from O mS/m
(O pS/cm) to 200 mS/m (2000 pS/cm).
5.2 Glass beaker, of convenient size and shape for housing the electrode end of the
conductometer (5.1) during measurement.
5.3 Standard adhesive patch, as specified in 4.1 of IS0 8502-6: 1995, e.g. of size A-1250.
NOTE- The patch should not cause any noticable contamination of the extraction liquid. Certain
patches are available today which are guaranteed to cause an ionic contamination of less than 7 mg/m2,
which is generally satisfactory. If there is no guarantee or if improved accuracy is required, then a blank
test is recommended.
5.4 Syringe, as specified in 4.2 of IS0 8502-61995.
6 Procedure
6.1 Preparation of water and blank test
6.1.1 Pour into the beaker (5.2) an amount of water (clause 4) that is just large enough for the
operation of the conductometer (5.1). Usually a volume between 10 ml and 20 ml is needed. To
prevent foreign matter inside the beaker and syringe, and on the conductometer probe, from
influencing the result, carry out the following blank test.
6.1.2 Completely fill the syringe (5.4) with water from the beaker. Then empty the syringe back
into the beaker.
6.1.3 Immerse the electrodes of the conductometer fully in the water in the beaker and agitate
gently. Record the conductivity (yi) and the units in which it is expressed, for example pS/cm.
6.2 Removal of salts from the steel surface
6.2.1 Follow the procedure specified in clause 5 of IS0 8502-6: 1995, subject to the following
specific requirements.
63.2 Fill the syringe with about one-quarter of the water contained in the beaker.
6.2.3 After 1 min, suck the water back into the syringe cylinder (see 5.6 of IS0 8502-6: 1995).

IS0 8502-9:1998(E)
6.2.4 Without removing the syringe needle from the patch, re-inject the water into the patch
compartment and then suck the water back into the syringe cylinder. Repeat until 10 cycles of
injection and sucking have been completed (see 5.7 of IS0 8502-6: 1995).
6.2.5 At the end of the 10th cycle, retrieve as much as possible of the water from the patch
compartment and transfer to the beaker (5.2), thus restoring its content to nearly the original
volume in 6.1.1 (see 5.8 of 8502-6:1 995).
6.3 Conductometric measurement
Immerse the electrodes of the conductometer fully in the now contaminated water in the beaker,
and record the conductivity (y2)e xpressed in the same units as in 6.1.3.
7 Expression of results
The total surface density pA of the salts is given by the equation
m

8 Accuracy
The accuracy of the method depends on the accuracy of the empirical constant c in equation (3),
and on the accuracy to which the variables in that equation can be determined. But other factors
will also have an influence on the accuracy, such as variations in temperature. Very little has
been published on these matters. Practical experience has shown, however, that most variations
have negligible influence on the overall accuracy, except that in the constant c, which is
dependent upon the types of salt dissolved in the water in 6.2.
In the majority of cases, the following types of ion are pre-dominant in the water: Cl-, S04",
HC03-, Na', Ca" and Fe". Other types of ion may also be present. Usually, however, their
contribution to the variation in the constant c is only marginal.
The value of the constant c (5 kg.m%') given in clause 7 is representative of what can be called
normal conditions. It is based on calculations of the total conductivity from the specific
conductivities of the individual ions extracted from ten rusty steel specimens. Should the
conditions be more extreme, e.g. due to some particular industry in the vicinity, the variation in
the constant c may amount to about & 12 %. This conclusion is drawn from calculations that are
based on the known specific conductance of each type of ion.
For more information about the method. see the introduction.

FOREWORD
This Indian Standard ( Part 2 ) was adopted by the Bureau of Indian Standards, atler the draft finalized by the
Building Construction Practices Sectional Committee had been approved by the Civil Engineering Division
Council.
Maintenance management in building industry is the art of preserving over a long period what has been
constructed. It is as important as construction management or even more. Whereas construction stage lasts for
a short period of 2 to 5 years, maintenance continues for atleast 20-30 times the construction phase. Bad
practice of maintenance adversely affects the environment in which people work, thus affecting the overall
output.
Even though the adverse effects of deterioration of abuilding are known, yet the process of maintenance of the
building is given a very low priority and most of the management decisions are taken by the management on
the basis of expediency, and in most of the cases are unrelated compromises between the physical needs and
availability of finance. It has been planned to publish the guidelines for maintenance management for buildings
in the following three parts:
1
a) Part 1 General,
b) Part 2 Finance, and
c) Part 3 Labour.
This part covers the aspects related to finance management.
This standard keeps in view the practices in the field of building maintenance management in the country.
Assistance has also been derived from BS 8210:1986 ‘Guide for Building Maintenance Management’, issued by
British Standards Institution.
The composition of the Committee responsible for the formulation of this standard isgiven at Annex A,
For the purpose of deciding whether aparticular requirement of this standard is complied with, the final value,
observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with
IS 2: 1960 ‘Rules for rounding off numerical values ( revised )’. The number of significant places retained
in the rounded off value should be the same as that of the specified value in this standard.IS 15183( Part 2 ): 2002

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of conformity
assessment, the ISO Committee on conformity assessment (CASCO) is responsible for the development of
International Standards and Guides.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
Draft International Standards are circulated to the national bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 17050-1 was prepared by the ISO Committee on conformity assessment (CASCO).
It was circulated for voting to the national bodies of both ISO and IEC, and was approved by both
organizations.
This first edition of ISO/IEC 17050-1, together with ISO/IEC 17050-2, cancels and replaces the second edition

Introduction
This part of ISO/IEC 17050 has been developed with the objective of providing general requirements for a
supplier’s declaration of conformity.
It addresses one of the three types of attestation of conformity, namely attestation undertaken by the first party
(e.g. the supplier of a product). Other types are second-party attestation (e.g. where a user issues an
attestation for the product the user is using) or third-party attestation. Each of these three types is used in the
market in order to increase confidence in the conformity of an object.
This part of ISO/IEC 17050 specifies requirements applicable when the individual or organization responsible
for fulfilment of specified requirements (supplier) provides a declaration that a product (including service),
process, management system, person or body is in conformity with specified requirements, which can include
normative documents such as standards, guides, technical specifications, laws and regulations. Such a
declaration of conformity can also make reference to the results of assessments by one or more first, second
or third parties. Such references are not to be interpreted as reducing the responsibility of the supplier in any
way.
These general requirements are applicable to all sectors. However, these requirements might need to be
supplemented for specific purposes, for example for use in connection with regulations.
A supplier's declaration of conformity of a product (including service), process, management system, person
or body to specified requirements can be substantiated by supporting documentation under the responsibility
of the supplier. In cases where this is desirable, or necessary, reference is made to ISO/IEC 17050-2.

NOTE 2 To avoid any confusion with attestation by certification bodies, the term “self-certification” is deprecated and
should not be used.
4 Purpose of the declaration of conformity
The purpose of the declaration is to give assurance of conformity of the identified object to specified
requirements to which the declaration refers, and to make clear who is responsible for that conformity and
declaration. A supplier’s declaration of conformity may be used alone or in conjunction with another conformity
assessment procedure for regulatory or non-regulatory purposes.

5 General requirements
The issuer (issuing organization or person) of a declaration of conformity shall be responsible for issuing,
maintaining, extending, reducing, suspending or withdrawing the declaration and the conformity of the object
to the specified requirements.
The declaration of conformity shall be based on results of an appropriate type of conformity assessment
activity (e.g. testing, measurement, auditing, inspection or examination) carried out by one or more first,
second or third parties. Conformity assessment bodies involved, where applicable, should consult relevant
International Standards, Guides and other normative documents.
Where a declaration of conformity is for a group of products of a similar type, it shall cover each individual
product of the group. Where a declaration of conformity is for similar products delivered over a period of time,
it shall cover each product as delivered or accepted.
It is recommended, as good conformity assessment practice, that the person reviewing the conformity
assessment results be different from the signatory.
6 Contents of the declaration of conformity
6.1 The issuer of the declaration of conformity shall ensure that the declaration contains sufficient
information to enable the recipient of the declaration of conformity to identify the issuer of the declaration, the
object of the declaration, the standards or other specified requirements with which conformity is declared, and
the person signing for and on behalf of the issuer of the declaration of conformity.
As a minimum, the declaration of conformity shall contain the following:
a) unique identification of the declaration of conformity;
b) the name and contact address of the issuer of the declaration of conformity;
c) the identification of the object of the declaration of conformity (e.g. name, type, date of production or
model number of a product, description of a process, management system, person or body, and/or other
relevant supplementary information);
d) the statement of conformity;
e) a complete and clear list of standards or other specified requirements, as well as the selected options, if
any;
f) the date and place of issue of the declaration of conformity;
g) the signature (or equivalent sign of validation), name and function of the authorized person(s) acting on
behalf of the issuer;
h) any limitation on the validity of the declaration of conformity.
6.2 Additional supporting information may be provided to relate the declaration to the conformity
assessment results on which it is based, for example:
a) the name and address of any conformity assessment body involved (e.g. testing or calibration laboratory,
inspection body, certification body);
b) reference to relevant conformity assessment reports, and the date of the reports;
c) reference to any management systems involved;

group).
References in the documentation to conformity assessment results shall not misrepresent their applicability
nor mislead the recipient of the declaration of conformity.
7 Form of declaration of conformity
See Annex A for an example of a declaration of conformity. The declaration of conformity may be in hardcopy,
electronic media, or any other suitable medium.
8 Accessibility
A copy of the declaration of conformity may be included in other documentation, such as a statement,
catalogue, invoice, user's instructions or website, relevant to the object of the declaration of conformity.
9 Product marking
If any marking is placed on the product to indicate the existence of a declaration of conformity, such marking
shall be in such a format that it will not be confused with any certification mark. Such marking shall be
traceable to the declaration of conformity.
10 Continuing validity of the declaration of conformity
10.1 The issuer of the declaration of conformity shall have procedures in place to ensure the continued
conformity of the object, as delivered or accepted, with the stated requirements of the declaration of
conformity.
10.2 The issuer of the declaration of conformity shall have procedures in place to re-evaluate the validity of
the declaration of conformity, in the event of
h) changes significantly affecting the object’s design or specification,
i) changes in the standards to which conformity of the object is stated,
j) changes in the ownership or structure of management of the supplier, if relevant, or
k) relevant information indicating that the object may no longer conform to the specified requirements.

Annex A
(informative)
Supplier's declaration of conformity
A.1 Guidance to complete the form of declaration of conformity
NOTE Numbers 1) to 7) refer to the form shown in A.2.
1) Every declaration of conformity should be uniquely identified.
2) The responsible issuer should be unequivocally specified. For large organizations, it may be necessary to
specify operational groups or departments.
3) a) The “object” should be unequivocally described so that the declaration of conformity may be related
to the object in question.
3) b) For mass-produced products, it is not necessary to give individual serial numbers. In such cases it is
sufficient to give the name, type, model number, etc.
4) For products, an alternative conformity statement may be: “As delivered, the object of the declaration
described above is in conformity with the requirements of the following documents”.
5) Requirements documents should be listed with their identification numbers, titles and dates of issue.
6) Text should appear here only if any limitation on the validity of the declaration of conformity and/or any
additional information are given. The latter information may, for example, correspond to 6.2 or may make
reference to related product marking in accordance with Clause 9. Such product marking or other
indication (e.g. on the product) may be an attachment to the declaration of conformity.
7) Full name and function of the signing person(s) authorised by the issuer's management to sign on its
behalf should be given. The number of signatures, or equivalent, included will be the minimum
determined by the legal form of the issuer’s organization.

FOREWORD
,
This Indian Standard was adopted by the Bureau of Indian Standards; after the draft finnlize by the Soil
Quality and Improvement Sectional Committee had been approved by the Food and A$kut ure Division
;
Council.
,
The electricat conductivity of water extract of soil is proportional to its salt concentration. There is no Indian
Standard procedure available for determination of electrical conductivity in various types of soils. Hence need
was felt to provide uniform method or determination -of electrical conductiviiy of soils.
r
In the preparation of ‘this r#andard, assistance has been derived from IS0 11265: 1994 ‘Soil quality -
Determination of the specific ekctrical conductivity’. Because of the typical national ago-climatic conditions
it has not been possible to ;dign with the above mentioned International~Standard.
For the purpose of deciding whether a particular requirement of this standard is cotnplied wi$, the final
value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance
with IS 2: 1960 ‘Rules for rwnding off numerical values (rcvisd)‘. The number of significant places retained
in the rounded off value shouM be the same as ~thato f the specified value in this standard.IS 14767 : 2000

SPECIFICATION FOR
BITUMEN PRIMER FOR USE IN
WATERPROOFING AND DAMP-PROOFING
(First Revision)
0. FOREWORD
0.1 This Indian Standard ( First Revision ) was adopted by the Indian
Standards Institution on 4 July 1986, after the draft finalized by the
Waterproofing and Damp-proofing Sectional Committee had been appro-
ved by the Civil Engineering Division Council.
0.2 Bitumen primer is commonly used for priming concrete and masonry
surfaces prior to the application of the first mopping coat of melted
bitumen in laying built-up roofings or membrane waterproofing, so as to
promote the bonding of the bitumen with the concrete roof deck or
masonry surface. This standard is intended to cover the minimum
requirements for bitumen primer for use in waterproofing and damp-
proofing of buildings. This standard was first published in 1965 and
the revision of this standard has been taken up to incorporate further
changes necessary in view of the revision of various standards referred
to in this standard. In this revision, in addition to carbon disulphide,
use of carbon tetrachloride and trichloroethylene have been permitted
for the requirements of primer. Sampling clause has been modified to
bring it in line with the other published Indian Standards.
1. SCOPE
1.1 This specification covers the requirements for bitumen primer for
application to concrete and masonry surfaces and to be used with
bitumen in damp-proofing and waterproofing below or above ground
level.
2. TERMINOLOGY

FOREWORD
This Indian Standard (First Revision) was adopted by the Bureau of Indian Standards, after the draft finalized
by the Dams and Reservoirs Sectional Committee had been approved by the Water Resources Division Council.
The opening of the contraction joints provides passages through the dam which unless sealed, would permit the
leakage of water from the reservoir to the downstream face. To stop this leakage, water-stops should be installed
in the joints adjacent to the upstream face.
Advancement inthe specifications and the manufacture of material have resulted inthe acceptance of polyvinyl
chloride (PVC) as suitable material for joint seal. The material can be manufactured for a number of shapes
and sizes suiting to the specific requirement. In view of this, the matter regarding the replacement of copper
water-stop and asphalt water-stop by PVC water-stops has been under consideration for quite some time.
Experience in India and abroad has suggested that asphalt water-stops become defunct for want of adequate
heating arrangement and as a result, ithas been felt that the same should be replaced by PVC water-stops.
Copper water-stops can accommodate only a small lateral movement. Experience in the Pacific North West of
United States has shown that the sheet-type copper water-stop isvery vulnerable to failure especially in high
navigation lock. In Indian condition, project authorities have reported difficulties in properly brazing the
copper sheets and also its missing from the structure during construction. Accordingly, ithas been felt that the
copper water-stop should be replaced by PVC water-stops. This standard was first published in 1987. [n this
revision of the standard use of only PVC water-stops have been recommended and provision of other materials
have been deleted.
There is no 1S0 standard on the subject. This standard has been prepared based on the data received from
indigenous manufacturers’ and also taking into consideration the pactices prevalent in the field in India.
The composition of the Committee responsible for the formulation of this standard is given in Annex A.
For the purpose of deciding whether aparticular requirement of this standard is complied withl the final value,
observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with
1S2: 1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained in
the rounded off value should be the same as that of the specified value in this standard.Is 12200:2001

METHOD OF MEASUREMENT OF
WORKS IN RIVER VALLEY PROJECTS
(DAMS AND APPURTENANT STRUCTURES)
PART 8 INSTRUMENTATION
0. FOREWORD
0.1 This Indian Standard was adopted by the Indian Standards Institution
on 25 November 1985 after the draft finalized by the Measurement of
Works of River Valley Projects Sectional Committee had been approved by
the Civil Engineering Division Council.
0.2 In measurement of quantities in construction of river valley projects a
large diversity of methods exist at present according to local practices.
This lack of uniformity creates complication regarding measurements and
payments. This standard is intended to provide guidance regarding a
uniform basis for measurement of instrumentation items in river valley
projects.
0.3 In reporting the results of measurement made in accordance with this
standard, if the final value, observed or calculated, is to be rounded off, it
shall be done in accordance with IS: 2-1960”.
1. SCOPE
1.1 This standard covers the method of measurement of work related to
instrumentation items in river valley projects.
2. GENERAL RULES
2.1 Clubbing of Item - Items may be clubbed together and that the break
up of the clubbed items are agreed to be on the basis of the detailed
description of the items stated in this standard.
2.2 Booking of Dimensions- In booking dimensions, the order shall be
consistent and generally in the sequence of length, width and height or
depth or thickness.
*Rules for rounding off numerical values ( revised ).
3IS : 9401( Part 8 ) - 1985
2.3 Description of Items - The description of each item shall unless and
otherwise stated, be held to include where necessary, conveyance and
delivery handling, unloading, storing, fabrication, hoisting all labour for
finishing to required shape and size setting, fitting and fixing in position,
straight cutting and waste return or packings, etc.
2.4 Measurement - All works shall be measured net in decimal system as
fixed in its place subject to the limitation: Linear dimensions shall be
measured to the nearest of 0.01 metre.
3. PLEZOMETERS
3.1 Porus tube piezometers (aluminum pipe ), thin tube hydraulic founda-
tions type piezometers and embankment piezometers shall be measured in
units of numbers and shall be designated in terms of R.D. (reduced
distance ), station number and elevation; and shall include the following:
a) All connected works pertaining to making of main trenches/offset
trenches in the compacted material of embankment ( in case of
embankment tips ) and backfilling and compacting the material in
specified layers after laying the tubing for tips, riser vertical steel
pipes for avoiding reverse slopes, steel housing for temporary
housing of the reels of the said tips.
b) The quantity of bentonite, mud/cement gravel, etc, if required;
c) The bore holes required to be made for foundation tips;
d) The installation and removal of casing pipe to maintain the holes
during installation of tip assembly;
e) Qrosole solution or wetting agent for circulation of water in tips,
boiiing of tips and boiling of water for filling pipes for taking pore
pressure measurement;
f) Epoxy rubber sheath wooden block and other petty items like black
conduit, tapes and plump bob item; and
g) Any wooden racks for facilitating the proper laying of twin tubes
in trench.
3.2 The PVC twin tube from the pipe to instrumentation house/well shall
be measured in running metres.
3.3 The pipes in case of porous tube piezometres shall be measured in
running metres stating diameter and the type of the pipe.
3.4 Typical Terminal well constructed in RCC or in some special cases
fabricated out of GI pipe shall be enumerated and shall include the
following:
a) Suitable measure like water proofing and painting of terminal well.
b) Ventilation system being provided in terminal wells.
4IS : 9401( Part 8 ) - 1985
3.5 The valves, gauges, panels, water tanks, pumps, plumbings and other
allied fittings required to furnish the instrumentation house/well shall be
enumerated.
4. CROSS ARMS
4.1 The cross arm assembly which includes pipes, tee, spacers and counter
weights along with its installation shall be measured in numbers.
5. MISCELLANEOUS INSTRUMENTS
5.1 Strain transducers, stress strain meters, reinforced bar stress transducer,
base load transducer, pore pressure transducer, uplift pressure transducer,
soil pressure transducer, dam level transducer (insertion type ), displacement
transducer, inclination transducer, temperature transducer, joint meter,
slope indicators, bore hole extensometer, hollow load cells, tiltmeters/
ground displacement transducers ( electronic type ), differential type
transducers along with accessories shall be measured in numbers.
5.2 Lead wire shall be measured in metres from installation of instrument
to the panel board in the control room.
5.3 Wherever bore hole is required to be done in vertical, horizontal or at
any inclination, it shall be measused in linear metre.
5.4 Wherever mounting angles or spiders for arresting the transducers are
required, these shall be enumerated.
5.5 Wherever junction boxes are required these shall be enumerated.
5.6 Wherever, pipes and sleeves are installed these shall be measured in
metres and diameter and class/type of pipe shall be designated.
5.7 Wherever grouting of anchor pipes are needed it shall be measured
separately [ see IS: 9401 ( Part 3 )-1980 *].
6. MISCELLANEOUS
6.1 Any dewatering in the area for installation of instrumentation shall be
measured separately [ see IS : 9401 ( Part 2 )-1980 71.
6.2 If monitoring is required after installation of instrument, it shall be
measured as a lump sum item indicating the period, numbers and type of
instruments.
