26、dification. 1 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 each other by a classification system based on appropriate level
27、s 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 of ISO 17855 is applicable to all polyethylene homopolymers and
28、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 ready for normal use in the form of powder, granules or pellets, unmo
29、dified 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 It is not intended to imply that materials having the same desig
30、nation 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 method of processing.If such additional properties are required, t
31、hey 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 requirements may be given in data block 5 (see Clause 3, introductory paragr
32、aph).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

37、al)International Standard number blockIndividual-item blockData block 1Data block 2Data block 3Data block 4Data block 5The designation consists of an optional description block, reading “Thermoplastics”, and an identity block comprising the International Standard number and an individual-item block.
38、 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 or PE-HD in accordance with ISO 1043-1 (see 3.1).Data block 2: Fillers or reinforcin

40、pecifications, 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 data block is not used, this shall be indicated by doubling the separation sign, i.e
41、. 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.DIN EN ISO 17855-1:2015-02 EN ISO 17855-1:2014 (E) 5 3.2 Data block 2In this data block, the type of f

Subsequently (without a space), the mass content may be given by a 2-figure number in positions 3 and 4.
