EN ISO 1622-1:2012 (E) DIN EN ISO 1622-1:2012-05 3 1 Scope1.1 This part of ISO 1622 establishes a system of designation for polystyrene thermoplastic material, which may be used as the basis for specifications.1.2 The types of polystyrene plastics are differentiated from each oth
24、er by a classification system based on appropriate levels of the designatory propertiesa) Vicat softening temperature andb) melt volume-flow rateand on information about the intended application and/or method of processing, important properties, additives and colorants.1.3 This part of ISO 1622 is a
25、pplicable to all amorphous polystyrene homopolymers.It applies to materials ready for normal use, unmodified or modified by colorants, additives, fillers, etc.This part of ISO 1622 does not apply to expanded polystyrene, styrene copolymers, homopolymers of substituted styrene or those modified with
26、other polymers such as elastomers.1.4 It is not intended to imply that materials having the same designation give necessarily the same performance. This part of ISO 1622 does not provide engineering data, performance data or data on processing conditions which might be required to specify a material
27、 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 Standard, if suitable.1.5 In order to specify a thermoplastic material for a particular applica
28、tion or to ensure reproducible processing, additional requirements may be given in data block 5 (see 3.1).2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the
29、 latest edition of the referenced document (including any amendments) applies.ISO 1043-1, Plastics Symbols and abbreviated terms Part 1: Basic polymers and their special characteristicsISO 1622-2, Plastics Polystyrene (PS) moulding and extrusion materials Part 2: Preparation of test specimens and de

31、lockData 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. For unambiguous designation, the individual-item block
32、 is subdivided into five data blocks comprising the following information: Data block 1: Identification of the plastic by its abbreviated term (PS) in accordance with ISO 1043-1 (see 3.2). Data block 2: Position 1: Intended application or method of processing (see 3.3).Positions 2 to 8: Important pr
33、operties, additives and supplementary information (see 3.3). Data block 3: Designatory properties (see 3.4). Data block 4: Fillers or reinforcing materials and their nominal content (not included in this part of ISO 1622). Data block 5: For the purpose of specifications, a fifth data block may be ad
34、ded containing additional information (see 3.5).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. by two commas ().3.2 Data block
35、1In this data block, after the hyphen, polystyrene plastics are identified by the abbreviated term “PS”, in accordance with ISO 1043-1.3.3 Data block 2In this data block, information about the intended application and/or method of processing is given in position 1 and information about important pro
36、perties, additives and colour in positions 2 to 8. The code-letters used are specified in Table 1.If information is presented in positions 2 to 8 and no specific information is given in position 1, the letter X shall be inserted in position 1.EN ISO 1622-1:2012 (E) DIN EN ISO 1622-1:2012-05 5 Table

The code-numbers are separated fr
39、om each other by hyphens.If a property value falls on or near a range limit, the manufacturer shall state which range will designate the material. If subsequent individual test values lie on, or on either side of, the limit because of manufacturing tolerances, the designation is not affected.3.4.2 V
