10、itish Standard has been prepared by Technical Committee PRI/61 and is the English language version of EN 1680 : 1997 Plastics piping systems Valves for polyethylene (PE) piping systems Test method for leaktightness under and after bending applied to the operating mechanism, published by the European
11、 Committee for Standardization (CEN). It is incorporated into BS 2782 Methods of testing plastics : Part 11 : Thermoplastics pipes, fittings and valves as Method 1133A : 1997, for association with related test methods for plastics materials and plastics piping components. This test method has been p
12、repared for reference by other standards under preparation by CEN for specification of plastics piping and ducting systems and components. It has been implemented to enable experience of the method to be gained and for use for other fresh applications. It is also for use for the revision or amendmen
13、t of other national standards as practicable, but it should not be presumed to apply to any existing standard or specification which contains or makes reference to a different test method until that standard/specification has been amended or revised to make reference to this method and adjust any re
14、quirements as appropriate.

In the descriptors, the term driving squares is irrelevant: it appears to be a mistranslation of a French descriptor for closing torque. The term cocks shoul

In 5.2, reference has been introduced to the same classification system of the pipes and the valve, without reference to the basis thereof. Technical Committee PRI/6
18、1 considers this to be a reference to the material classification number according to EN ISO 12162 : 1995 (” BS EN ISO 12162 : 1996 and BS 2782 : Part 11 : Method 1121 : 1996) NOTE 4.

19、tee PRI/61 considers this to be a reference to maximum operating pressure (MOP) according to prEN 12008-1 Specific functional recommendations for PE systems MOP#10 bar and that otherwise the relevant MOP has to be identified by the standard making reference to this standard as though this was a furt

This British Standard, which is identical with EN 1680 : 1997, does not necessarily detail all the precautions necessary to meet the requirements of the Health and Safety at Work etc. Act 1974. Attention should
21、be paid to any appropriate safety precautions and the method should be operated only by trained personnel. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, the
