20、SO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, gov
21、ernmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC
22、 Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of t
23、he elements of this part of ISO 11542 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 11542-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials. This sec
24、ond edition cancels and replaces the first edition (ISO 11542-1:1994), which has been technically revised. The major change is that density has been replaced by Charpy notched impact strength as one of the designatory properties. ISO 11542 consists of the following parts, under the general title Pla

26、ics Ultra-high-molecular-weight polyethylene (PE-UHMW) moulding and extrusion materials Part 1: Designation system and basis for specifications 1 Scope 1.1 This part of ISO 11542 establishes a system of designation for PE-UHMW thermoplastic materials which may be used as the basis for specifications
27、. For the purposes of this part of ISO 11542, PE-UHMW materials are polyethylene materials having a melt mass- flow rate (MFR), measured at 190 C and 21,6 kg load, of less than 0,1 g/10 min. 1.2 The types of PE-UHMW are differentiated from each other by a classification system based on appropriate l
28、evels of the designatory properties a) viscosity number b) elongational stress c) Charpy notched impact strength and on information about intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. 1.3 This part of ISO 11542 is app
29、licable to all PE-UHMW homopolymers and to ultra-high-molecular-weight copolymers of ethylene having a content of other 1-olefinic monomers of less than 50 % by mass and a content of non-olefinic monomers with functional groups up to a maximum of 3 % by mass. It applies to materials ready for normal
30、 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 necessarily the same performance. This part of ISO 11542 does not provide engineering data, p
31、erformance 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 in part 2 of this International St
32、andard, if suitable. 1.5 In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see 3.1). 2 Normative references The following normative documents contain provisions which, through referenc
33、e in this text, constitute provisions of this part of ISO 11542. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply.

38、ntity 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 of the plastic by its symbol PE-UHMW in accordance with ISO
39、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). Data block 4: Fillers or reinforcing materials and their nomi
40、nal 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 shall be separated from each other by commas. If a data block is no
41、t used, this shall be indicated by doubling the separation sign, i.e. by two commas (,). 1) To be published.

42、 with ISO 1043-1. 3.3 Data block 2 In this data block, information about intended application and/or method of processing is given in position 1 and information about important properties, additives and colour in positions 2 to 8. The code-letters used are specified in Table 1. If information is pre
43、sented in positions 2 to 8 and no specific information is given in position 1, the letter X shall be inserted in position 1.

46、strength by a single-figure code-number (see 3.4.4). The code-numbers are separated from each other by hyphens. ENISO115421:2001 ISO -245111:(1002E) 4 If a property value falls on or near a range limit, the manufacturer shall state which range will designate the material. If subsequent individual te
47、st values lie on, or either side of, the limit because of manufacturing tolerances, the designation is not affected. NOTE Not all combinations of the values of the designatory properties may be possible for currently available polymers. 3.4.2 Viscosity number The viscosity number shall be determined
48、 in accordance with ISO 1628-3, using a nitrogen atmosphere. The possible values of viscosity number are divided into six ranges, each represented by a single-figure code- number, as specified in Table 2. Only materials with code-numbers 1 to 5 in Table 2 shall be used if the abrasion resistance of the material is important to the application. Table 2 Ranges of viscosity number in data block 3 C
