23、n ISO 12086-1 and the test methods in ISO 12086-2 43 Bibliography . 45 EN ISO 12086-2:2006iv 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
24、 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 represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO
25、 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International 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 Internation
26、al Standards. 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. Attention is drawn to the possibility that some of the elem
27、ents of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 12086-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials. This second edition cancels and replaces the fi
28、rst edition (ISO 12086-2:1995), which has been technically revised. ISO 12086 consists of the following parts, under the general title Plastics Fluoropolymer dispersions and moulding and extrusion materials: Part 1: Designation system and basis for specifications Part 2: Preparation of test specimen
29、s and determination of properties EN ISO 12086-2:20061Plastics Fluoropolymer dispersions and moulding and extrusion materials Part 2: Preparation of test specimens and determination of properties SAFETY STATEMENT Persons using this document should be familiar with normal laboratory practice, if appl
30、icable. This document does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any regulatory requirements. The warnings in Subclauses 8.6.2.1, 9.7
31、and 10.6.1.4 point out specific hazards. 1 Scope 1.1 This part of ISO 12086 describes the preparation of test specimens and provides test methods to define characteristics of thermoplastic fluoropolymer resins. Results from the testing may be used as the basis for designation, material specification
32、s or both. This part of ISO 12086 describes the conditions of test for determining both designatory and other properties of the homopolymers and various copolymers of fluoromonomers, as dispersions or powders for moulding, extrusion and other uses. The test procedures included are appropriate for, b
33、ut are not restricted to, the fluoropolymers listed in Clause 4 and for which designatory properties are specified in ISO 12086-1. 1.2 The properties of semi-finished and finished products made from fluoropolymer resins depend on the material used, the shape of the product, the physical and morpholo
34、gical state of the material resulting from the processing operations, and on the test conditions. Therefore, to obtain reproducible test results, the defined methods of preparation of test specimens and defined test conditions given in this part of ISO 12086 must be applied. 1.3 Agreements between v
35、endor and purchaser should preferably be based on properties measured using the specimens and test conditions described in this part of ISO 12086. 2 Normative references The following referenced documents are indispensable for the application of this document.
