10、6 Plastics piping systems Thermoplastics valves Test method for the integrity of a valve after an external blow, published by the European Committee for Standardization (CEN). It is incorporated into BS 2782 Methods of testing plastics : Part 11 : Thermoplastics pipes, fittings and valves, as Method
11、 1133C : 1997, for association with related test methods for plastics materials and plastics piping components. This test method has been prepared for reference by other standards under preparation by CEN for specification of plastics piping and ducting systems and components. It has been implemente
12、d 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 amendment 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
13、to a different test method until that standard/specification has been amended or revised to make reference to this method and adjust any requirements as appropriate.

In the descriptors, the term driving squares
15、 is irrelevant: it appears to be a mistranslation of a French descriptor for closing torque. The term cocks should be read as valves. NOTE 2. For consistency, the term closing torque used, only, in 6.5 should be read as stop torque as used in 6.3 and in item b) in the note to clause 3. Warning note.
16、 This British Standard, which is identical with EN 1705 : 1996, does not necessarily detail all the precautions necessary to meet the requirements of the Health and Safety at Work etc. Act 1974. Attention should be paid to any appropriate safety precautions and the method should be operated only by
17、trained personnel. In particular, it is the opinion of UK Technical Committee PRI/61 that the method as written gives test conditions known to be appropriate and required for some applications, including polyethylene valves for gas distribution. For testing of valves of more brittle materials and/or
18、 intended for other applications, the test conditions may be inappropriate, e.g. conditioning to 220 C as required for 6.1.3 and 6.1.4, The Technical Committee therefore draws particular attention to clause 3 and the note thereto, including item c), and to the notes which follow 6.1.5 and 6.6.
