11、 under the direction of the Sector Board for Materials and Chemicals and is the English language version of EN ISO 9969:1995 Thermoplastics pipes Determination of ring stiffness, published by the European Committee for Standardization (CEN). It is incorporated into BS 2782 Methods of testing plastic
12、s Part 11: Thermoplastics pipes, fittings and valves, as Method 1114B:1995, for association with related test methods for plastics materials and plastics piping components. This test method has been accepted for reference by other standards under preparation by CEN for specification of plastics pipi
13、ng 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 amendment of other national standards as practicable, but it should not be presumed to apply to any existing standard or
14、 specification which contains or makes reference to a different test method until this standard/specification has been amended or revised to make reference to this method and adjust any requirements as appropriate. WARNING NOTE. This British Standard, which is the English language version of EN ISO
15、9969:1995, 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 trained personnel. A British Standard does not purpor
16、t to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. 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 cov
