22、 739 IS0 1622-2:1995(E) 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 technical committees. Each member body interested in
23、 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 with the International Electrotechnical Commiss
24、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. Internation
25、al Standard IS0 1622-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials. This second edition cancels and replaces the first edition (IS0 1622-2:1980) and includes the following changes: The text has been brought into accordance with the frame text d
26、eveloped by SC 9. The table of test methods has been revised in accordance with IS0 10350. IS0 1622 consists of the following parts, under the general title Plastics - Polystyrene (PS) moulding and extrusion materials: - Pan 7: Designation system and basis for specifications - Pan 2: Preparation of
27、test specimens and determination of proper- ties II STD.BSI 8s EN IS0 lb22-2-ENGL m II624669 0807702 b75 INTERNATIONAL STANDARD IS0 1622-2:1995(E) Plastics - Polystyrene (PS) moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties 1 Scope This part of
28、 IS0 1622 specifies the methods of prep- aration of test specimens and the test methods to be used in determining the propenies of PS moulding and extrusion materials. Requirements for handling test material and for conditioning both the test ma- terial before moulding and the specimens before testi
29、ng are given here. Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize PS mould- ing and extrusion material
30、s are listed. The properties have been selected from the general test methods in IS0 10350. Other test methods in wide use for or of particular significance to these moulding and extrusion materials are also included in this part of IS0 1622, as are the designatory proper- ties specified in part 1.
31、In order to obtain reproducible and comparable test results, it is necessary to use the methods cf speci- men preparation and conditioning, the specimen di- mensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtained using specimens of dif
32、ferent dimen- sions or prepared using different procedures. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IS0 1622. At the time of publication, the editions indicated were valid. All standards are subjec
