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. Esch 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
collaborates closely with the International Electrotechnical Commission
(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.
International Standard ISO 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
(ISO 1622-2:1980) and includes the following changes:
The text has been brought into accordance with the frame text developed
by SC 9. The table of test methods has been revised in accordance with
ISO 10350.
ISO 1622 consists of the following Parts, under the general title
Plas tics - Polystyrene (PS) moulding and extrusion materials:
- Part 1: Designation System and basis for specifications
- Part 2: Preparation of fest specimens and determination of proper-
