The work of preparing International Standards is norma
20、lly carried out through IS0 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 th
21、e work. IS0 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 ISOAEC Directives, Part 3. Draft International Standards adopted by the technica
22、l 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 elements of this part of IS0 3672 may be the subject of patent rights.
23、IS0 shall not be held responsible for identifying any or all such patent rights. International Standard IS0 3672-2 was prepared by Technical Committee ISO/TC 61, Plasfics, Subcommittee SC 12, Thermoseffing maferials. IS0 3672 consists of the following parts, under the general title Plasfics - Unsafu
24、rafed-polyesfer resins (UP-R): - Par 1: Designafion sysfem - Par 2: Preparafion of fesf specimens and deferminafion of properies iv O IS0 0002 -All rights rsedevre 9 egaP EN IS0 3672-22001 I nt rod u cti on The purpose of this part of IS0 3672 is to designate procedures for the determination of intr
25、insic properties of unsaturated-polyester (UP) resins. It specifies procedures and conditions for the preparation of test specimens of unsaturated-polyester resins in a specified state, and methods for measuring their properties. Those properties and test methods which are suitable and necessary for
26、 characterizing unsaturated-polyester resins are listed. Because of the specificity of thermosetting resins like unsaturated-polyester resins, contrary to other plastic products, a distinction is made between the presentation of the properties before crosslinking (characteristics which are useful fo
27、r processing) and after crosslinking (intrinsic characteristics). O IS0 0002 -All rights rsedevre V EN IS0 3672-22001 Plastics - Unsaturated-polyester resins (UP-R) - Part 2: Preparation of test specimens and determination of properties WARNING - Persons using this part of IS0 3672 should be familia
28、r with normal laboratory practice. This part of IS0 3672 does not purport to address all of the safety problems, 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 national regulatory conditions
29、. 1 Scope This part of IS0 3672 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of unsaturated-polyester resins. Requirements for handling test material and for conditioning both the test material before moulding and the specimens
30、before testing are given here. The properties of crosslinked unsaturated-polyester resins have been selected from the general test methods in IS0 10350-1. Other test methods in wide use for, or of particular significance to, unsaturated-polyester resins (particularly properties useful for the proces
31、sing of non-crosslinked resins) are also included in this part of IS0 3672. In order to obtain reproducible and comparable test results, it is necessary to use the test methods, sample preparation and conditioning procedures, and specimen dimensions specified herein. Values determined will not neces
32、sarily be identical to those obtained using specimens of different dimensions or prepared using different procedures. Other standards exist concerning the determination of properties and preparation of test specimens for unsaturated-polyester-based products, to which reference will be made, if requi
