Full title and description

ISO 293:1974 — Plastics — Compression moulding test specimens of thermoplastic materials. This International Standard specifies the shape and dimensions of test specimens produced by compression moulding for the determination of physical and mechanical properties of thermoplastic materials. A Russian-language edition/translation of the ISO text is commercially available from standards resellers (catalogued as "St ISO 293-1974 rus").

Abstract

ISO 293:1974 defines the form, nominal dimensions and basic preparation requirements for compression‑moulded specimens intended for use in laboratory tests of thermoplastic materials. The document provides standardized specimen geometry to ensure interlaboratory comparability of test results and to facilitate consistent specimen production by moulding operations.

Scope

This standard applies to the manufacture by compression moulding of standard test specimens from thermoplastic materials and specifies the shape and nominal dimensions of those specimens. It is intended to be used where compression‑moulded specimens are needed for mechanical and physical testing so that results are comparable between laboratories and manufacturers.

Key topics and requirements

• Specification of specimen shape and nominal dimensions for compression‑moulded thermoplastic test pieces.
• Basic requirements for moulding practice to obtain specimens suitable for mechanical and physical testing.
• Provision for reproducible specimen preparation to support reliable interlaboratory comparison.
• Reference to test methods that use the specified specimen geometries (for tensile, flexural and other physical property determinations).

Typical use and users

Used by plastics testing laboratories, materials R&D groups, quality control departments in plastics manufacturing, test-house laboratories and standards committees when compression‑moulded specimens are required for property evaluation and comparison. Also referenced by educators and researchers working on thermoplastic material characterization.

Related standards

ISO 293:1974 was revised by a later edition (ISO 293:1986) and cataloguing information indicates a much newer version of ISO 293 is available (ISO 293:2023). Users should consult the current ISO catalogue entry to determine the normative replacement and to obtain the up‑to‑date text for specimen dimensions and related requirements.

FAQ

Q: What is this standard?

A: ISO 293:1974 is an international standard that specified the shape and dimensions of compression‑moulded test specimens for thermoplastic materials.

Q: What does it cover?

A: It covers the geometry and nominal dimensions of test specimens produced by compression moulding so they are suitable for common laboratory tests of thermoplastic properties (tensile, flexural and related determinations).

Q: Who typically uses it?

A: Plastics testing laboratories, manufacturers of thermoplastics, R&D groups, quality control personnel, conformity assessment bodies and educators in materials science and polymer engineering.

Q: Is it current or superseded?

A: ISO 293:1974 has been withdrawn (withdrawal recorded in 1986) and was revised by a later edition (ISO 293:1986); a more recent ISO 293 edition (ISO 293:2023) is indicated in the ISO catalogue as the current replacement. Users should consult the latest ISO publication for current requirements.

Q: Is it part of a series?

A: ISO 293 sits within ISO technical work on plastics testing (ISO/TC 61) and is associated with other specimen and test method standards for plastics; later revisions and related standards address specimen preparation and specific test methods.

Q: What are the key keywords?

A: Plastics, thermoplastics, compression moulding, test specimen, specimen dimensions, ISO 293.
