Suggestions for improvements will be recorded and in due course brought to the notice of the committees charged with the revision of the standards to which they refer. A complete list of British Standards, numbering over 5 000, fully indexed and with a note of th

16、e contents of each, will be found in the British Standards Yearbook, The BS Yearbook may be consulted in many public libraries and similar institutions. This standard makes reference to the following British Standards: BS 509, Acetone. BS 2782, Methods of testing plastics. BS 3505, Unplasticized PVC

17、 pipe for cold water services. BS 3867, Dimensions of pipes of plastics materials (outside diameters and pressure ratings). BS 4159, Colour marking of plastics pipes to indicate pressure ratings. CP, Plastics pipework (thermoplastic material) 1) . This British Standard has been prepared under the au

18、thority of the Plastics Industry Standards Committee. It is based on a draft submitted by the British Plastics Federation. In the present issue, Table 1 specifies dimensions that are in accordance with BS3867 2) . These dimensions and also the other requirements of the standard are the same, as far

19、as possible, as those specified in BS3505 3) . Classes B, C, D and E are identical to those specified in BS3505 3)whilst ClassesO,6and7are provided to give dimensions suitable for non-pressure duct applications and for extra thick pipes for hazardous duty and screw threading. To avoid possible confu

20、sion during the period of transition to full metric thinking, it has been decided that the sizes, although dimensioned in metric units, should be designated using nominal size description corresponding to the established values in inches. Maximum sustained working pressures, tensile strength and hyd

21、raulic stress levels are specified in bars 4)but Appendix H is included giving equivalent values in technical metric and imperial units. Attention is drawn to CP 5)which is being prepared to assist users in assessing the suitability of plastics pipes for particular purposes and to ensure their prope

22、r application. Pipes complying with this standard should not be used to convey potable water, for which purpose pipes complying with BS3505 3)are suitable. 1) In course of preparation. 2) BS 3867 “Dimensions of pipes of plastics materials (outside diameters and pressure ratings)”. 3) BS 3505 “Unplas

26、lasticized polyvinyl chloride pipe up to and including24in nominal size, for industrial purposes. One series of thinner wall pipes and one of thicker wall pipes are included in addition to those covered by BS3505 6) . 1.2 Pipe complying with BS3505 6)is deemed to comply with the requirements for cor

27、responding classes in this standard. 2 Material 2.1 The material from which the pipe is produced shall consist substantially of polyvinyl chloride, to which may be added only those additives that are needed to facilitate the manufacture of the polymer, and the production of sound, durable pipe of go

28、od surface finish, mechanical strength and opacity. None of these additives shall be used separately or together in quantities sufficient to impair the fabrication or welding properties of the pipe, or to impair its chemical and physical properties (in particular long-term mechanical strength and im

29、pact strength) as defined in this standard. 2.2 The addition of the manufacturers own rework material produced during the manufacture and works testing of pipe complying with this standard, is permissible. No other rework material shall be used. 2.3 When tested by Method102J of BS2782 7) , the defor

30、mation temperature of the material under load shall not be lower than75 C. 3 Designation of dimensional characteristics Pipe dimensions shall be designated by the nominal size. Outside diameters shall conform to Table 1 of BS3867 8) . 4 Classification of pipes Pipes are classified as follows: 5 Dime

31、nsions Pipes shall conform to the outside diameters and wall thicknesses specified in Table 1. Determine the wall thickness at not less than six points around the circumference of the pipe ensuring that the least and greatest values of wall thickness are included. Calculate the mean of these determi

32、nations which shall not exceed the value given in the appropriate column of Table 1 headed averaged value, max. NOTEThe maximum averaged wall thickness is based on a tolerance of+0.1e +0.2mm (with a minimum value of0.3mm). The maximum individual value is based on a tolerance of+0.15e or+0.1e +0.2 mm

33、, whichever is the greater, where e is the minimum wall thickness. 6) BS 3505, “Unplasticized PVC pipe for cold water services”. 7) BS 2782 “Methods of testing plastics”. 8) BS 3867 “Dimensions of pipes of plastics materials (outside diameters and pressure ratings)”.
