FOREWORDThis Indian Standard ( First Revision ) was adopted by the Bureau of Indian Standards on 27 March1990, after the draft finalized by the Chemical Engineering Plants and Related Equipment SectionalCommittee had been approved by the Heavy Mechanical Engineering Division Council.Lack of uniformity of colour coding of pipelines in industrial installations has often been responsiblefor destruction of property and injury to personnel due to faulty manipulations of values,particularly when outside agencies, like fire-fighting squads, are called in. Uniformity of colourmarking promotes greater safety, lessens the chances of error and reduces hazards involved in thehandling of material inside the pipelines.Identification of the particular contents of the pipelines is achieved by imposing suitable colourbands on the ground colour. Lettering, as a mode of identification, is also recommended forchemical industry as this will reduce the possibility of mistakes in identification. Lettering mayinclude the contents by name, chemical formula, or by unmistakable and commonly understoodabbreviations.This standard was first published in 1963. The present revision is based on the prevailing practicesin the industry. In this revision use of legends have been recommended for various types ofhazards. Hydrocarbon, Naptha and some more chemicals and allied products have been includedin the standard. The title of the standard is also revised to bring it in line with the latestguidelines.In the formulation of this standard assistance has been derived from the following publications:

BS 1710 : 1984 Specification for identification of pipelines and services. BritishStandards Institution.ASA A 13.1-1981 Scheme for the identification of piping systems, American NationalStandards Institute.

( First Revision )1 SCOPEThis Indian standard covers the colour schemefor the identification of the contents of pipelinescarrying fluids in domestic and public buildingsand such industrial installations where a specificcolour code does not exist.1.1 For the purpose of this standard, pipingsystems shall include pipes of any kind and inaddition fittings, valves, and pipe coverings.Supports, brackets or other accessories arespecifically excluded from application of thisstandard.1.2 This standard is not applicable to pipelinesburied underground or used for electricalservices.2 REFERENCES2.1 The following Indian standards are necessaryadjuncts to this standard:

4.2 It is recommended that the paints usedshould produce a glossy finish.5 COLOURS5.1 In order to identify the contents of thepipelines, a large number of colour shades arerequired. Recommendation regarding shades ocolours that may be used are given in IS 5 : 1978.f6 IDENTIFICATIONThe system of colour coding consists of a groundcolour and colour bands superimposed on it.6.1 Ground ColoursThe ground colour identifies the basic nature ofthe fluid carried ( see Fig. 1 ) and also dis-tinguishes one fluid from another, for examplewater from oil. The various ground colours areindicated in Table 1.6.1.1 Ground colour shall be applied throughoutthe entire length for uninsulated pipes, forinsulated pipes, on the metal cladding or on thepipes of material such as non-ferrous metals,austenitic stainless steel, plastic, etc, groundcolour coating of minimum 2 m length or ofadequate length, not to be mistaken as colourband, shall be applied.6.2 Colonr BandsColour bands are superimposed on the groundcolour ( see Fig. 2 ) to distinguish:

a) One kind or condition of a fluid fromanother kind or condition of the samefluid, orb) One fluid from another but belonging tothe same group, for example carbonmonoxide from coke oven gas or dieselfuel from furnace fuel.

7 APPLICATION7.1 Ground ColourColours as given in Table 1 shall be applied inone of the following ways:

a)b)

444

Throughout the entire length ( see Fig. 1A );As a colour coating of adequate length,( but in no case less than 300 mm) sothat it is not mistaken for a colour band( see Fig. IB );As a colour panel;On a label attached to the pipe; orBy the use of coloured adhesive tapes ofsuitable material.
