Full title and description

ISO 604:2002 — Plastics — Determination of compressive properties. This International Standard specifies a laboratory method to determine compressive behaviour of plastics (compressive strength, compressive modulus, yield and stress/strain relationship) using defined specimen shapes, conditioning and test speeds; it is intended for rigid and semi-rigid thermoplastics, thermosets and certain liquid-crystal polymers under the conditions described in the standard.

Abstract

The standard defines specimen dimensions and preparation options (including specimens machined from multipurpose test specimens), test conditioning, loading rates and calculation/reporting conventions to obtain comparable compressive property data for moulding and extrusion materials, filled/reinforced short-fibre compounds (fibre length ≤ 7.5 mm) and similar plastics. It also lists material types and situations for which the method is not normally suitable.

Scope

Specifies a test method for determining compressive properties of standard test specimens of plastics under defined pretreatment, temperature, humidity and machine-speed conditions. The method applies to rigid and semi-rigid thermoplastics and thermosets (including filled and short-fibre reinforced compounds with fibre lengths ≤ 7.5 mm), and thermotropic liquid-crystal polymers. It is not normally suitable for textile-fibre reinforcements, fibre-reinforced composites/laminates, rigid cellular materials or sandwich constructions containing cellular materials or rubber.

Key topics and requirements

• Specified specimen geometries and preferred dimensions (with allowance to adjust length to avoid buckling).
• Requirements for specimen preparation and conditioning (temperature, humidity, pre-treatment).
• Defined test speeds and machine-conditioning to ensure comparable strain-rate conditions.
• Reporting of compressive modulus, compressive yield/stress, compressive strength and stress–strain behaviour.
• Notes on applicability and exclusions (e.g., textile-reinforced composites, sandwich structures, rigid cellular materials).

These technical requirements and recommended reporting practices are intended to give reproducible, comparable single-point and curve data for material selection, R&D and quality control.

Typical use and users

Used by materials testing laboratories, polymer manufacturers, compounders, quality-control personnel, R&D engineers, product designers and standards writers who need standardized compressive-property data for plastics selection, verification and specification. The method is commonly used alongside or compared to regional equivalents (for example ASTM D695 in North America).

Related standards

Commonly referenced and related documents include ISO 3167 (multipurpose test specimens — machining of specimens referenced by ISO 604), the ISO 10350 series (presentation and acquisition of comparable single-point data; ISO 10350-1/2 references for reinforced/unreinforced materials), and equivalent methods such as ASTM D695 (Standard Test Method for Compressive Properties of Rigid Plastics). These documents are used together to ensure specimen preparation, data acquisition and reporting are consistent.

FAQ

Q: What is this standard?

A: ISO 604:2002 is the International Standard that defines the laboratory method for determining compressive properties of plastics (Edition 3, published March 2002).

Q: What does it cover?

A: It covers specimen preparation options, conditioning, machine and test-speed specifications, calculation of compressive modulus and strength, yield definitions and reporting conventions for rigid and semi-rigid plastics (with stated exclusions and limitations).

Q: Who typically uses it?

A: Materials testing laboratories, polymer producers, compound formulators, R&D and quality-control teams, and standards developers use ISO 604 when they need standardized compressive-property data. It is often used in parallel with regional equivalents like ASTM D695.

Q: Is it current or superseded?

A: ISO 604:2002 (Edition 3) is the published version and has been subject to ISO systematic review and confirmation (the edition was confirmed during reviews, most recently in 2022); the 2002 edition replaced earlier editions (1973, 1993). Users should check ISO or national bodies for any later amendments or re-confirmations before purchase.

Q: Is it part of a series?

A: It is commonly used alongside other plastics test and data-reporting standards such as ISO 3167 (multipurpose test specimens) and the ISO 10350 series (acquisition and presentation of comparable single-point data). Equivalent national/regional standards (e.g., ASTM D695) are noted as technically equivalent for many purposes.

Q: What are the key keywords?

A: Compressive modulus, compressive strength, compression test, plastics, specimen preparation, conditioning, ISO 604, ASTM D695, ISO 3167, ISO 10350.
