The British Standards BS /BS are globally recognised norms. The usage of pipe markers compliant to the BS and ducts will increase your plant. The British Standards Institution • i BS BRITISH STANDARD Foreword Publishing information This British Standard is published by BSI. BS Basic Identification Colours and Colour Code Indication. BS Specification for Identification of Pipelines and Services. RAL Color Chart BS

December This updated version of BS specifies the colours and other information that should be used to identify pipes, ducts and electrical conduits. BS outlines the requirements for colours for identifying pipes conveying fluids in above ground and below ground installations. This includes ducts for ventilation and conduits used for carrying electrical services. Improved regulations from the water supply industry now require explicit content relating to different pipes, to avoid any form of contaminated drinking water. BS supports the legal requirement for those who install and use plumbing systems to prevent cross contamination. BSI Essentials:

Who is this standard for? This is a revised standard.

The new version: Refines the labelling system to aid identification Simplifies identification in building and water systems Introduces a new three-size methodology to accommodate the full range of fluid services Removes ship systems, which are now covered in BS ISO Standard Number BS Your basket.

The basic identification colour shall be applied either over the whole length of the pipe or by colour banding at points specified in 4. Where the basic identification colour is applied over the whole length of pipe, the code indications in 6.

Where the basic identification colour is in the form of banding see 4.

Where required, code indications as specified in 6. If the pipes are colour banded, the code indication shall be either on or adjacent to the colour band. The names, abbreviations or chemical symbols shall be either white or black in order to contrast clearly with the colour of the pipe or with the basic identification colour.

They shall be placed directly on the pipe or on a label fixed to the pipe adjacent to the basic identification colour band. When labels are to be used on an installation in combination with a safety colour, the background colour of the labels shall be that of the safety colour.

The service identifier shall be composed of the basic identification colour for the particular family of fluids for example, for gas, the outside colour bands would be yellow ochre — 08 C 35 and a centre code or safety colour band indicating the variant within the family of the fluid for example, natural gas centre band colour would be primrose — 10 E The centre code or safety colour band shall be the colours specified in 6. Where no specification exists, the method of identification by the use of additional code colours except for water services, see Annex F , or by supplementary information see 8.

The dimensions of the service identifier as it relates to the diameter of the service or the external surface of any insulation or external covering shall be of the dimensions detailed in a to c below. All code or safety colours shall be of equal width and accommodated within the dimensions of the code or safety colour. The minimum service identification dimensions shall be: Figure 2 Application of safety colours and code colours Key 1 Basic identification colour a Dimensions as identified in 7.

Reference should be made to Table 1 for the relevant BS colour number. Figure 3 and Figure 4 provide examples of direction of flow arrows and supplementary information in use with the service identifier. The colours in Figures 3 and 4 are illustrative only. Code identification labels shall allow the ready identification of different pressures, qualities and designated uses of services. The text font shall be of a type and of sufficient size to enable it to be easily read and shall be a minimum of 5 mm in height.

Where fluids are able to flow in either direction e. The direction of flow of the fluid shall be indicated by an arrow or arrows situated in the banding or immediately adjacent to it. The arrow shall be coloured white or black in order to contrast clearly with the basic identification colour or the background of the pipe or its covering.

For central heating systems and other closed circuits where it is necessary to indicate separately the flow and return pipes, the direction of flow arrows shall be supplemented by the use of the word FLOW or the letter F on the one pipe, and the word RETURN or the letter R on the other.

Additionally there are applications that not only require the colour coding but also safety colours and labels. Figure A. Figure B. Medical gas service identifiers for standard and pathology services shall be applied in accordance with Figure C.

Table C. B All pathology services should be identified by an additional golden brown code colour band and an additional PATH supplementary information label on the left side basic identification colour band. NOTE 1 The colour names in these examples are illustrative only.

NOTE 2 The widths of the basic identification and code indication colours should be as specified in 7. Examples include fuel oils, gases, electrical conduits, air. General building services shall be identified in accordance with Table D. When specifying colours, the colour references given in Table 1 shall be stated. Table D. Where water is utilized, these should be identified as a water service see Annex F. B Waste effluents conveyed for treatment at municipal treatment works or similar facilities, prior to discharge back to the environment, should be identified as a general building service.

This includes the conveyance of waste effluents upstream of any recycling or water reuse treatment system. Waste effluents which are for direct reuse e. Waste effluents which have been subject to treatment and are intended for reuse e. NOTE The widths of the basic identification and code colours should be as specified in 7. When specifying colours, the colour references given in Table 1, and Table E. NOTE The nature of the contents of refrigeration service pipes should also be indicated by the chemical symbol.

Table E. The term water services refers to services containing fluids in which water is a constituent and which have been drawn from a public or private water supply, or other alternative sources.

These services include a range of uses where water might be the primary fluid, e. The primary purpose for ensuring pipework is readily distinguishable is to reduce the risk of alterations being made to pipes and fittings by those who are unaware of the nature of the fluids being conveyed. Alterations can result in drinking water and non-potable systems being directly connected, resulting in drinking water contamination.

The following method simplifies service identification to ensure maintenance staff, users or occupiers can readily identify the nature of the source water, safety systems and whether systems pose any risk to public health from fluids contained within, if they were to be inadvertently connected to a potable water system and subsequently contaminate it.

Water services shall be identified using the following assessment in accordance with Table F. Figure F. Supplementary information see 8.

Water services shall be identified in accordance with the basic identification, safety and code colours for water services specified in Table F. B Waste effluents which are for direct reuse e. Waste effluents conveyed for treatment, at municipal treatment works or similar, prior to discharge back to the environment, should be identified as a general building service see Annex D. D Domestic hot water which would otherwise meet the requirements for potable water except for it being heated should be designated potable.

Domestic hot water which has been treated or contain additives or chemical compounds in concentrations which exceed the standards for drinking water should be designated non-potable.

E Hydraulic power utilizing water is to be identified as a water service. Where oil is utilized, it is to be identified as a building service see Annex D. F Fire-fighting systems supplied direct from the drinking water supply mains and containing no additives may, following an assessment, be considered for potable designation.

For all other systems, or where there is doubt regarding the water quality, these should be designated as non-potable systems. Examples include fire systems supplied from storage or containing additives. NOTE The basic identification colour for water services is green. NOTE 2 The widths of the basic identification, safety and code colours should be as specified in 7.
