Endorsement notice The text of ISO 1622-1:2012 has been approved by CEN as a EN ISO 1622-1:2012 without any modification. BS EN ISO 1622-1:2012ISO 1622-1:2012(E)ForewordISO (the International Organizat

16、ion 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 established h

17、as 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 standardization.Inte

18、rnational Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publicat

19、ion 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 the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent right

20、s.ISO 1622-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials.This third edition cancels and replaces the second edition (ISO 1622-1:1994), which has been technically revised. The main change is the replacement of melt flow rate (MFR) by melt volume

21、-flow rate (MVR) as one of the designatory properties (see, in particular, Subclauses 1.2 and 3.4.3).ISO 1622 consists of the following parts, under the general title Plastics Polystyrene (PS) moulding and extrusion materials: Part 1: Designation system and basis for specifications Part 2: Preparati

23、signation for polystyrene thermoplastic material, which may be used as the basis for specifications.1.2 The types of polystyrene plastics are differentiated from each other by a classification system based on appropriate levels of the designatory propertiesa) Vicat softening temperature andb) melt v

25、nts, additives, fillers, etc.This part of ISO 1622 does not apply to expanded polystyrene, styrene copolymers, homopolymers of substituted styrene or those modified with other polymers such as elastomers.1.4 It is not intended to imply that materials having the same designation give necessarily the

26、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 for a particular application and/or method of processing.If such additional properties are required, they shall be determined in

27、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 application or to ensure reproducible processing, additional requirements may be given in data block 5 (see 3.1).2 Normative referencesTh

31、esignation 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 is subdivided into five data blocks comprising the following informa

32、tion: 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 properties, additives and supplementary information (see 3.3). Data blo

33、ck 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 added containing additional information (see 3.5).The first character o

34、f 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 1In this data block, after the hyphen, polystyrene plastics are ident

35、ified 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 properties, additives and colour in positions 2 to 8.

38、.1 GeneralIn this data block, the range of the Vicat softening temperature is represented by a three-figure code-number (see 3.4.2) and the range of the melt volume-flow rate by a two-figure code-number (see 3.4.3). The code-numbers are separated from each other by hyphens.If a property value falls

39、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 Vicat softening temperatureThe Vicat softening tempe

40、rature shall be determined in accordance with ISO 1622-2.The possible values of Vicat softening temperature are divided into four ranges, each represented by a three-figure code-number as specified in Table 2.Table 2 Range of Vicat softening temperature in data block 3Code-numberRange of Vicat softe
