No.DateText affected National foreword This British Standard is the English language version of EN 12099 : 1997 published by the European Committee for Standardization (CEN). The UK pa
5、rticipation in its preparation was entrusted to Technical Committee PRI/61, Plastics piping systems and components, which has the responsibility to: aid enquirers to understand the text; present to the responsible European committee any enquiries on the interpretation, or proposals for change, and k
6、eep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. This European Standard is also incorporated into BS 2782 Methods of testing plastic
7、s : Part 11 Thermoplastics pipes, fitting and valves, as Method 1103E : 1997, for association with related test methods for plastics materials and plastics piping systems. It is also for use for the revision or amendment of other national standards as practicable, but it should not be presumed to ap
8、ply 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 any requirements adjusted as appropriate. NOTE : Subclause 4.1 states that test pieces may be
9、cut from a cross-section of a pipe or fitting. For a test method for determining the content of volatile material, it is essential that the cutting technique does not heat the test piece to an extent that would expel any material and thereby affect the results. In the absence of any related instruct
10、ions by a referring standard, the responsible BSI committee considers that the cutting method should not induce any tangible heating or involve any coolant which could be adsorbed. Warning note. This British Standard, which is identical with EN 12099 : 1997, does not necessarily detail all the preca
11、utions 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 trained personnel. Compliance with a British Standard does not of itself confer immunity from legal oblig
12、ations. Summary of pages This document comprises a front cover, an inside front cover, the EN title page, pages 2 to 4, an inside back cover and a back cover.
