Full title and description
ASTM D695-23 — Standard Test Method for Compressive Properties of Rigid Plastics. This ASTM test method specifies procedures for determining compressive strength, compressive modulus, and other compressive properties of unreinforced and reinforced rigid plastics (including high‑modulus composites) using standard specimen shapes and controlled compression rates.
Abstract
ASTM D695-23 describes a laboratory procedure to measure the compressive behavior of rigid plastic materials under relatively low uniform rates of straining or loading. The method applies to a wide range of rigid plastics and composite systems (up to a specified composite modulus limit) and provides test‑condition, specimen, and reporting requirements to generate comparable compressive property data. The standard is technically equivalent to ISO 604.

Scope
This test method covers determination of compressive mechanical properties of unreinforced and reinforced rigid plastics, including high‑modulus composites, when loaded in compression at relatively low, uniform rates of straining or loading. It applies to standard specimen shapes and is applicable for composite moduli up to and including 41,370 MPa (6,000,000 psi). The values in SI units are the standard; inch‑pound units are shown for information only. Note: for certain resin‑matrix composites other ASTM composite procedures (for example D3410/D3410M or D6641/D6641M) may be more appropriate. The method is declared equivalent to ISO 604.
Key topics and requirements
- Specimen geometry and preparation requirements for standard compression specimens.
- Test machine setup, platen alignment, and calibration / verification practices for force and displacement measurements.
- Controlled, relatively low uniform rates of straining/loading and their effect on reported properties.
- Measurement and reporting of compressive strength, compressive modulus (elastic modulus in compression), and strain at specified conditions.
- Applicability limit for composite modulus (up to 41,370 MPa / 6,000,000 psi) and guidance on when alternate composite test methods are recommended.
Typical use and users
Used by materials laboratories, polymer/composite manufacturers, quality assurance and R&D teams, certification bodies, and defense or procurement organizations requiring standardized compressive property data for rigid plastics and plastic‑matrix composites. Typical applications include material specification verification, comparative material screening, design input for structural components, and failure analysis.
