22、ion) 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 has the right to be r
23、epresented 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. Draft International Sta
24、ndards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO 1060-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcomm
25、ittee SC 9, Thermoplastic materials. This second edition cancels and replaces the first edition (ISO 1060-1:1982) and includes the following main changes: a) the viscosity and the type of rheological behaviour of standard pastes have been introduced as designatory properties for paste resins; b) ret
26、ention on a 63 4m sieve has been introduced as a designatory property; c) plasticizer absorption has been introduced as a designatory property. ISO 1060 consists of the following parts, under the general title Plastics Homopolymer and copolymer resins of vinyl chloride: Part 1: Designation system an
27、d basis for specifications; Part 2: Preparation of test samples and determination of properties.iv blankENISO1060-1:1999 BSI 02-2000 1 1 Scope 1.1 This part of ISO 1060 establishes a system of designation for vinyl chloride thermoplastic resins, which may be used as the basis for specifications. 1.2
28、 The types of vinyl chloride plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties: a) reduced viscosity b) apparent density c) retention on a 63 4m mesh sieve d) plasticizer absorption at room temperature (for general-purpos
29、e resins and filler resins only) e) the viscosity and the type of rheological behaviour of a standard paste (for paste resins only) and on information about basic polymer parameters, polymerization processes and intended applications. 1.3 This part of ISO 1060 is applicable to resins in powder form
30、which consist of homopolymers of the monomer vinyl chloride and copolymers, terpolymers, etc., of vinyl chloride with one or more other monomers, but where vinyl chloride is the main constituent. The resins may contain small amounts of non-polymerized substances (e.g.emulsifying or suspending agents
31、, catalyst residues, etc.) and other substances added during the course of polymerization. 1.4 It is not intended to imply that materials having the same designation give necessarily the same performance. This part of ISO 1060 does not provide engineering data, performance data or data on processing
32、 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 Standard, if suitable. 1.5 In order to
33、specify a resin for a particular application or to ensure reproducible processing, additional requirements may be given in data block5 (see clause 3, introductory paragraph). 2 Normative references The following standards contain provisions which, through reference in this text, constitute provision
34、s of this part of ISO 1060. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO 1060 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated bel
35、ow. Members of IEC and ISO maintain registers of currently valid International Standards.

36、 samples and determination of properties. 3 Designation and specification system The designation and specification system for thermoplastics is based on the following standardized pattern: The designation consists of an optional description block, reading “Thermoplastics”, and an identity block comp
37、rising the International Standard number and an individual-item block. For unambiguous designation, the individual-item block is subdivided into five data blocks providing the following information: Designation Description block (optional) Identity block International Standard number block Individua
38、l-item block Data block 1 Data block 2 Data block 3 Data block 4 Data block 5 Data block 1: Identification of the plastic by its symbol (PVC, etc.) in accordance with ISO 1043-1 and information about the polymerization process and the composition of the polymer (see 3.1).ENISO1060-1:1999 2 BSI 02-20
39、00 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 (,). 3.1 Data block 1 In this data block, after the hyphen, vin
40、yl chloride polymer resins are identified by the symbol PVC or VC/./. for homopolymers or copolymers/terpolymers respectively, in accordance with ISO 1043-1, followed, for copolymers/terpolymers, by a space and by a two-figure number indicating the percentage content of combined vinyl chloride. This
41、 is calculated from the chlorine content determined in accordance with ISO 1060-2, using the equation VC = 1,762 9 CI After a hyphen, the polymerization process is indicated by a single code-letter as specified in Table 1.

42、 block 2 In this data block, information about intended application is given. The code-letters used are specified in Table 2. Table 2 Code-letters used in data block 2 3.3 Data block 3 In this data block, the reduced viscosity is represented by a three-figure code-number (see 3.3.1), the apparent bu
43、lk density by a two-figure code-number (see 3.3.2) and retention on a63 4m mesh sieve by a two-figure code-number (see 3.3.3). For general-purpose resins and filler resins, the plasticizer absorption at room temperature is represented by a two-figure code-number (see 3.3.4). For paste resins, the vi
44、scosity of a standard paste is represented by a letter indicating the paste formulation used, two two-figure code-numbers for the viscosity at 16 s 1and100 s 1and a code-letter indicating the type of rheological behaviour of the paste (see 3.3.5). The codes representing the four designatory properti
45、es are separated from 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 range limit because of manufacturing tolerances, the designati
46、on is not affected. NOTENot all combinations of the values of designatory properties are provided in currently available polymers. Data block 2: Intended application (see 3.2).
