12、Reinforced plastics pipes, fittings and valves, as Methods 1214A and B : 1997, for association with related test methods for plastics materials and plastics piping components, where method 1214A corresponds to method A of EN 1228 (using constant load) and method 1214B corresponds to method B of EN 1
13、228 (using constant deflection). This standard has been prepared for reference by other standards under preparation by CEN for specification of reinforced plastics piping systems and components. It has been implemented to enable experience of the methods to be gained and for use for other fresh appl
14、ications. 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 to a different test method until that standard/specification has been amended or r
15、evised to make reference to this method and adjust any requirements as appropriate. No existing British Standard is superseded by this Method.

16、dentical with EN 1228 : 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 trained personnel. Compliance with
