21、-2:1999 BSI 03-2000 iii Foreword ISO (the International Organization 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
22、 a subject for which a technical committee has been established 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 Commiss
23、ion (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75% of the member bodies casting a vote. Internationa
24、l Standard ISO 1060-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials. This third edition cancels and replaces the second edition (ISO 1060-2:1985) and includes the following main changes: a) the list of test methods in Table 1 has been revised; b)
25、 the preparation of standard pastes has been included. ISO 1060 consists of the following parts, under the general title Plastics Homopolymer and copolymer resins of vinyl chloride: Part 1: Designation system and basis for specifications; Part 2: Preparation of test samples and determination of prop
26、erties.iv blankEN ISO 1060-2:1999 BSI 03-2000 1 1 Scope This part of ISO 1060 specified the methods of preparation of test samples and the test methods to be used in determining the properties of PVC resins. Requirements for handling test material and for conditioning the material before testing are
27、 given here. In addition, properties and test methods which are suitable and necessary to characterize PVC resins are listed. In order to obtain reproducible and comparable test results, it is necessary to use the methods of sample preparation and conditioning and the test procedures specified herei
28、n. Values determined will not necessarily be identical to those obtained using different test samples, or test samples prepared using different procedures. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of I
29、SO 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 below.
