The UK participation in its preparation was entrusted to Technical Committee PRI/42, Fibre reinforced thermose

5、tting plastics and prepregs, which has 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

6、 developments and promulgate them in the 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 p

7、ublications with their corresponding European 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

22、pecifications 1 Scope 1.1 This part of ISO 14527 establishes a data block system for the designation of urea-formaldehyde and urea/melamine-formaldehyde powder moulding compounds (UF- and UF/MF-PMCs). 1.2 The various types of UF- and UF/MF-PMC are differentiated from each other by a classification s

23、ystem 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 purposes (designatory properties). 1.3 This part of ISO 14527 is applicable to all UF- and UF/MF

24、-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 14527 does not provide engineering data, performance data or data on processing conditions

25、 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 in ISO 14527-2, if suitable. 1.5 Whenever general requirement data, as covered by

26、ISO 14527-3, 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 code-numbers for use in data block 1, 2 or 3 shall be approved before use by the s

27、ecretariats 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 14527. For dated references, subsequent amendments to, or revisions of, any of these publicatio

37、reading “PMC“, and an identity block comprising the International Standard number and an individual-item block. For unambiguous designation, the individual-item block is subdivided into five data blocks comprising the following information: Data block 1: Marking block Item 1: Identification of the b

38、asic polymer by its symbol, in accordance with ISO 1043-1; Item 2: Nature of the designatory reinforcement materials or fillers, in accordance with ISO 1043-2; Item 3: Form of the designatory reinforcement materials or fillers, in accordance with ISO 1043-2; Item 4: Nominal content of the designator

39、y reinforcement materials or fillers, in accordance with Table 1. Data block 2: Method of processing Method of processing for which the moulding compound is intended, designated in accordance with Table 2. Data block 3: Properties Item 1: Special properties, in accordance with Table 3; Item 2: Desig

40、natory property No. 1 impact strength determined in accordance with ISO 179-1; Item 3: Designatory property No. 2 temperature resistance determined in accordance with ISO 75-2. Data block 4: Further information, taken from an international, national or company standard. Data block 5 (optional): Addi

41、tional requirements The first character of the individual-item block shall be a hyphen. The data blocks shall be separated from each other by commas. If a data block is not used, this shall be indicated by an “X“ (= not applicable), but only if another block follows. For labelling purposes, and prov

42、ided no other blocks follow, the comma between blocks 1 and 2 can be omitted. There is no need to fill in data blocks if they are not required. 4.2 Data block 1 Item 1: After the hyphen, urea-formaldehyde or urea/melamine-formaldehyde powder moulding compounds shall be identified by the symbol UF or

43、 UF/MF, in accordance with ISO 1043-1. Mixtures and modifications shall be designated in accordance with ISO 1043-1:1997, subclauses 4 and 5. The following information shall be restricted to designatory fillers/reinforcements used in the material in question: Item 2: Nature of filler/reinforcement,

44、in accordance with Table 1. Item 3: Form of filler/reinforcement, in accordance with Table 1. Item 4: Nominal content (mass %) of filler/reinforcement, in accordance with Table 1. Note, in particular, the following: the same code-letters have different meanings when used for item 2 and item 3; whene

45、ver information needs to be indicated only for item 3, an “X“ ( = not applicable) is required for item 2.

46、in Table 2. The code-letter used to indicate the intended method of processing in data block 2 shall be selected carefully. Certain brands of material can be processed in more than one way, e.g. either by compression moulding (Q) or by injection moulding (M). Such brands shall be designated “general

47、 purpose“ (G). The designation of special methods of processing shall be reserved for specially modified materials.
