4、o. Date Comments National foreword This British Standard is the English language version of EN ISO 14526-2:1999. It is identical with ISO 14526-2:1999. The UK participation in its preparation was entrusted to Technical Committee PRI/42, Fibre reinforced thermosetting plastics and prepregs, which has
5、 the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in t
6、he UK. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding E
7、uropean publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A
8、 British Standard does not purport 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

21、on of test specimens and determination of properties 1 Scope This part of ISO 14526 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of phenolic powder moulding compounds (PF-PMCs). Requirements for handling test material and for co
22、nditioning both the test material before moulding and the specimens before testing are given here. Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which
23、 are suitable and necessary to characterize PMCs are listed. The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use for, or of particular significance to, PMCs are also included in this part of ISO 14526, as are the designatory properties found
24、 in ISO 14526-1. In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and conditioning, the specimen dimensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtained using specimens of
25、 different dimensions or prepared using different procedures. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 14526.
