17、rganization for Standardization) is a worldwide federation of national standards bodies (ISO 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 estab
18、lished 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. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardizat
19、ion.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with
20、 the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directivesAttention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

25、d extrusion materials Part 1: Designation system and basis for specifications1 Scope1.1 This part of ISO 17855 establishes a system of designation for polyethylene thermoplastic material, which may be used as the basis for specifications.1.2 The types of polyethylene plastics are differentiated from
26、 each other by a classification system based on appropriate levels of the designatory propertiesa) density,b) melt mass-flow rate,and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.1.3 This part
27、 of ISO 17855 is applicable to all polyethylene homopolymers and to copolymers of ethylene having a content of other 1-olefinic monomers of less than 50 % (mass fraction) and a content of non-olefinic monomers with functional groups up to a maximum of 3 % (mass fraction).It applies to materials read
28、y for normal use in the form of powder, granules or pellets, unmodified or modified by colorants, additives, fillers, etc.This part of ISO 17855 does not apply to masterbatches or to EPM rubber. This part of ISO 17855 also does not apply to PE-UHMW. It should reference to ISO 11542-1 for PE-UHMW.1.4
29、 It is not intended to imply that materials having the same designation give necessarily the same performance. This part of ISO 17855 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 m
30、ethod of processing.If such additional properties are required, they shall be determined in accordance with the test methods specified in ISO 1872-2, if suitable.1.5 In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirement

For unambiguous designation, 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-VLD, PE-LD, PE-LLD, PE-MD
38、 or PE-HD in accordance with ISO 1043-1 (see 3.1).Data block 2: Fillers or reinforcing materials and their nominal content (see 3.2).Data block 3: Position 1: Intended application or method of processing (see 3.3).Positions 2 to 8: Important properties, additives and supplementary information (see 3
39、.3).Data block 4: Designatory properties (see 3.4).Data block 5: For the purpose of specifications, a fifth data block may be added containing addi-tional information.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
40、 data block is not used, this shall be indicated by doubling the separation sign, i.e. by two commas (,).3.1 Data block 1In this data block, after the hyphen, polyethylene plastics are indentified by the symbol “PE-VLD, PE-LD, PE-LLD, PE-MD or PE-HD “, in accordance with ISO 1043-1.2 ISO 2014 All ri
