21、 des proprits Reference number IS0 14527-2:1999(E) EN IS0 14527-2:1999 Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 techn
22、ical 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. IS0 collaborates closely
23、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 technical committees are circulated to th
24、e 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 14527 may be the subject of patent rights. IS0 shall not be held responsibl
25、e for identifying any or all such patent rights. International Standard IS0 14527-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 12, Thermosetting materials. After a transition period of, at the most, four years, the three parts of IS0 14527 (see below), together with the
26、 three parts of IS0 14528, will replace IS0 21 12:1990, of which they constitute a technical revision. IS0 14527 consists of the following parts, under the general title Plastics - Urea-formaldehyde and uredmelamine-formaldehyde powder moulding compounds (UF- and UF/MF-PMCs): - Part 1: Designation s
27、ystem and basis for specifications - Part 2: Preparation of test specimens and determination of properties - Part 3: Requirements for selected moulding compounds Previous page is blank iii lb24bb9 0823400 42s = EN IS0 14627-2:1999 Plastics - Urea-formaldehyde and urea/melamine-formaldehyde powder mo
28、ulding compounds (UF- and UF/MF-PMCs) - Part 2: Preparation of test specimens and determination of properties 1 Scope This part of IS0 14527 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of urea-formaldehyde and uredmelamine-form
29、aldehyde powder moulding compounds (UF- and UF/MF-PMCs). Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given here. Procedures and conditions for the preparation of test specimens and procedures for measuring p
30、roperties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize PMCs are listed. The properties have been selected from the general test methods in IS0 10350-1. Other test methods in wide use for, or of particular
31、 significance to, PMCs are also included in this part of IS0 14527, as are the designatory properties found in IS0 14527-1. In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and conditioning, the specimen dimensions and the test procedures
32、 specified herein. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provi
