This European Standard is incorporated into BS 2782 Methods of testing plastics : Part 11: Thermoplastics pipes, fittings and v
5、alves, as Method 1133D, for association with related test methods for plastics materials and plastics piping components. The UK participation in its preparation was entrusted to Technical Committee PRI/61, Plastics piping systems and components, which has the responsibility to: aid enquirers to unde
6、rstand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on
7、 this committee can be obtained on request to its secretary. The responsible UK Technical Committee considers that it is necessary to clarify the combination of figure 1 and the text of sub-clause 6.1 in respect of a) the orientation of figure 1; b) whether and how compensation should be made to the
8、 force to be applied in accordance with 6.3 in any arrangement where the weight of the test piece would interact with the specified force. With the operating member now shown in figure 1, vertical and opposite the point of application of the force as required by 6.1.1 in conjunction with a reference
9、 to the figure, together with the instruction in 6.1.4 to place the test piece on the supports S the UK Technical Committee has concluded that for consistency, figure 1 should be regarded as though it is an elevation view with the downward direction towards the top of the page. In this condition, th
10、e UK Technical Committee considers that the force should be applied at the value specified in accordance with 6.3.1 and item c) of the note to clause 3, with the effect of the weight of the test piece incidentally supplementing that of the applied force. The UK Technical Committee considers that fig
11、ure 1 should not be presumed to represent an elevation view with the force applied upwards and the test piece restrained by overhead supports, because the effect of the weight of the test piece would then oppose the applied force and undermine the rigour of the test, as well as being inconsistent wi
