18、rd IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technic
19、al committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of el
20、ectrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard require
21、s approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of IS0 11542 may be the subject of patent rights. IS0 shall not be held responsible for identifying any or all such patent rights. International Standard IS0

This second edition cancels and replaces the first edition (IS0 11542-1 :1994), which has been technically revised. The major change is that density has been replaced by Charpy notched impac

This p
25、art of IS0 11542 establishes a system of designation for PE-UHMW thermoplastic materials which For the purposes of this part of IS0 11542, PE-UHMW materials are polyethylene materials having a melt mass- flow rate (MFR), measured at 190 OC and 21,6 kg load, of less than 0,l g/lO min. 1.2 levels of t
26、he designatory properties The types of PE-UHMW are differentiated from each other by a classification system based on appropriate a) viscosity number b) elongational stress c) Charpy notched impact strength and on information about intended application and/or method of processing, important properti
27、es, additives, colorants, fillers and reinforcing materials. 1.3 This part of IS0 11542 is applicable to all PE-UHMW homopolymers and to ultra-high-molecular-weight copolymers of ethylene having a content of other l-olefinic monomers of less than 50 % by mass and a content of non-olefinic monomers w
28、ith functional groups up to a maximum of 3 % by mass. It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc. 1.4 It is not intended to imply that materials having the same designation give
29、 necessarily the same performance. This part of IS0 11 542 does 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
30、 be determined in accordance with the test methods specified in part 2 of this International Standard, if suitable. 1.5 additional requirements may be given in data block 5 (see 3.1).

36、al description block, reading ”Thermoplastics”, and an identity block comprising the International Standard number and an individual-item block. For unambiguous coding, the individual-item block is subdivided into five data blocks comprising the following information: - Data block 1: Identification
37、of the plastic by its symbol PE-UHMW in accordance with IS0 1043-1 (see 3.2). - Data block 2: Position 1: Intended application or method of processing (see 3.3). Positions 2 to 8: Important properties, additives and supplementary information (see 3.3). - Data block 3: Designatory properties (see 3.4
38、). - Data block 4: Fillers or reinforcing materials and their nominal content (see 3.5) - Data block 5: For the purpose of specifications, a fifth data block may be added containing additional information (see 3.6). The first character of the individual-item block shall be a hyphen. The data blocks
39、shall be separated from each other by commas. If a data block is not used, this shall be indicated by doubling the separation sign, .e. by two commas (,). 1) To be published.
