CGSB is engaged in the production
3、 of voluntary standards in a wide range of subject areas through the media of standards committees and the consensus process. The standards committees are composed of representatives of relevant interests including producers, consumers and other users, retailers, governments, educational institution
4、s, technical, professional and trade societies, and research and testing organizations. Any given standard is developed on the consensus of views expressed by such representatives. The Ministers Advisory Council on CGSB reviews the results of the consensus process. CGSB has been accredited by the St
5、andards Council of Canada as a national standards-writing organization. The standards that it develops and offers as National Standards of Canada conform to the criteria and procedures established for this purpose by the Standards Council of Canada. In addition to standards it publishes as national
6、standards, CGSB produces standards to meet particular needs, in response to requests from a variety of sources in both the public and private sectors. Both CGSB standards and national standards developed by CGSB are developed in conformance with the policies described in the Policy Manual for the De
7、velopment and Maintenance of Standards by CGSB. CGSB standards are subject to review and revision at any time, so as to ensure that they keep abreast of technological progress. Suggestions for their improvement, which are always welcome, should be brought to the notice of the standards committees co
8、ncerned. Changes to standards are issued either as separate amendment sheets or in new editions of standards. An up-to-date listing of CGSB standards, including details on latest issues and amendments, and ordering instructions, will be found in the CGSB Catalogue, which is published annually and is
9、 available without charge upon request. Although the intended primary application of this standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. Many tests required by CGSB standa
10、rds are inherently hazardous. CGSB neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed. CGSB takes no position respecting the validity of any patent rights asserted with any item connected with this standard. Use
11、rs of this standar are expressly advised that determination of the validity of any such patent rights are entirely their own responsibi I ity.

12、ANDARDS COUNCIL OF CANADA is the Co-ordinating body of the National Standards System, a federation of independent, autonomous organizations working towards the further development and improvement of voluntary standardization in the national interest. The principal objectives of the Council are to fo
13、ster and promote voluntary standardization as a means of advancing the national economy, benefiting the health, safety and welfare of the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international co-operation in the field of standards.
14、 A National Standard of Canada is a standard which has been approved by the Standards Council of Canada and one which reflects a reasonable agreement among the views of a number of capable individuals whose collective interests provide, to the greatest practicable extent, a balance of representation
15、 of producers, users, consumers and others with relevant interests, as may be appropriate to the subject in hand. It normally is a standard that is capable of making a significant and timely contribution to the national interest. Approval of a standard as a National Standard of Canada indicates that
16、 a standard conforms to the criteria and procedures established by the Standards Council of Canada. Approval does not refer to the technical content of the standard; this remains the continuing responsibility of the accredited standards-writing organization. Those who have a need to apply standards
17、are encouraged to use National Standards of Canada whenever practicable. These standards are subject to periodic review; therefore, users are cautioned to obtain the latest edition from the organization preparing the standard. The responsibility for approving National Standards of Canada rests with

27、3-92 Supersedes 24-GP-3a September 1967 CANAIDIAN GENERAL STANDARDS BOARD IDENTIFICATION OF PIPING SYSTEMS SCOPE This standard specifies the means for ready identification of materials contained in piping systems, including pipes buried in the ground and electricall conduits, by means of background
28、colour marking, legend and, in some cases, pictogram(s). This standard does not apply to piping systems in which medical gases are conveyed. Identification of medical gas piping systems is covered by CANICGSB-24.2-M86, Identification of Medical Gas Containers, Pipelines and Valves. The use of this s
29、tandard will resiilt in greater safety by reducing chances of error, simplifying the handling of emergencies, and minimizing hazards to personnel. This standard does not fully addre:ss the needs of individuals who are colour blind or illiterate. The testing and evaluation of a product against this s
30、tandard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health an
31、d safety practices in conjunction with any existing applicable regulatory requirements prior to its use.

Oxidizing Material - A substance that can cause some other materials to burn intensely by reacting with them to d. Poisonous and Infectious Material - A substance that can cause serious health effects by
37、exposure to it. It may produce heat and oxygen. contain bacteria or viruses that can cause disease. There are 3 types as follows: 1. Materials causing immediate and serious toxic effects 2. Materials causing other toxic effects 3. Biohazardous infectious material. e. Corrosive Material - A substance
38、 that will “eat away“, burn or destroy some materials, including human tissue. f. Dangerously Reactive Material - A material that is likely to become reactive by itself, in contact with other chemicals or when subject to changes in pressure or temperature. A reactive material may explode, burn, or g
39、ive off toxic vapours. Pipes - Conduits for electrical conductors and for the transport of gases, liquids or solids (or any combination thereof) or as a carrier of solids carried in liquids or gas or air lines. Piping systems - It shall include pipes of any kind, fittings, valves, vessels, other pla
40、nt equipment, and pipe coverings. Supports, brackets or other accessories are specifically excluded from application of this standard. CLASSIFICATION (BY CONTENT) Hazardous Materials Controlled products which are as defined in par. 3.1. All electrical conduit, with the exception of control circuits
41、designated as Class 2 circuits or telephone circuits as specified in Sections 16 and 60 respectively of the Canadian Electrical Code, Part 1. Materials at high temperature or pressure. For some materials, temperatures as low as 60C or pressures as low as 275 kPa can be hazardous. Inherently Low Haza
42、rd Materiais Materials which are not hazardous by nature, and are at ambient pressure and temperature such that people working on systems carrying these materials experience minimal risk through the release of these materials. Control circuits designated as Class 2 circuits or telephone circuits as
43、specified in Sections 16 and 60 respectively of the Canadian Electrical Code, Part 1. Fire Protection Materials Sprinkler systems and other piped fire fighting or fire protection equipment. This includes water (for fire fighting), foam, COZ, Halon and dry chemical systems. Some fire protection mater
44、ials may also be hazardous (see par. 4.1 and 4. i .3). In such cases, these materials shall adhere to fire protection material identification. GENERAL REQUIREMENTS Identification of material contained in a piping system shall be by background colour marking and legend. For controlled products, picto
45、grams shall also be used. The background colour marking and coloured pictograms are used to designate whether the contained material is hazardous, or for fire protection. The identification shall be produced by the use of paint, decals, plastic bands or polyethylene or detectable ribbon (see par. 7.
46、1). The identification marking material shall have good weathering, moisture and wrinkling resistance and adhesion properties. 2 CAN/CGSB-24.3-92 Copyright Canadian General Standards Board Provided by IHS under license with CGSBNot for ResaleNo reproduction or networking permitted without license fr
