4、. Date Comments National foreword This British Standard is the English language version of EN ISO 14528-1:1999. It is identical with ISO 14528-1:1999. 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 th
6、e 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 Eu
7、ropean publications. The British Standards which implement international or European publications referred to in this document 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 E
8、lectronic Catalogue. A 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 Thi

21、 ISO 9991 All irhgts seredevr 1 Plastics Melamine-formaldehyde powder moulding compounds (MF-PMCs) Part 1: Designation system and basis for specifications 1 Scope 1.1 This part of ISO 14528 establishes a data block system for the designation of melamine-formaldehyde powder moulding compounds (MF-PMC
22、s). 1.2 The various types of MF-PMC are differentiated from each other by a classification system based on information about the filler/reinforcement type and content, the intended method of processing, any special properties and those of the special properties used specifically for designation purp
23、oses (designatory properties). 1.3 This part of ISO 14528 is applicable to all MF-PMCs ready for normal use in the form of powder, granules or ground material. 1.4 It is not intended to imply that materials having the same designation necessarily give the same performance. This part of ISO 14528 doe
24、s not provide engineering data, performance data or data on processing conditions which may be required to specify a material for a particular application and/or method of processing. If such additional properties are required, they shall be determined in accordance with the test methods specified i
25、n ISO 14528-2, if suitable. 1.5 Whenever general requirement data, as covered by ISO 14528-3, need to be indicated, this is also done using this data block system. 1.6 To ensure that code-letters and code-numbers remain unambiguous, and to avoid conflicts within the system, any new code-letters or c
26、ode-numbers for use in data block 1, 2 or 3 shall be approved before use by the secretariats of ISO/TC 61/SC 1, SC 12 and SC 13. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 14528. For dat
27、ed references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 14528 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated
28、references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

33、abbreviation for powder moulding compound is PMC by analogy with bulk moulding compound (BMC) and sheet moulding compound (SMC). 3.2 MF-PMC abbreviation for powder moulding compounds based on melamine-formaldehyde resins for both injection and compression moulding 4 Designation system 4.1 General Th
34、e designation system defined in this part of ISO 14528 is based on the following standardized pattern: Designation Identity block Description ISO Individual-item block block Standard Data block 1 Data block 2 Data block 3 Data block 4 Data block 5 The designation consists of an optional description
35、block, reading “PMC“, and an identity block comprising the International Standard number and an individual-item block.
