Overview

EN ISO 10350-2:2020 - Plastics: Acquisition and presentation of comparable single-point data - Part 2: Long-fibre‑reinforced plastics (ISO 10350-2:2020) defines standardized methods to obtain and present comparable single‑point property data for long‑fibre‑reinforced thermoplastic and thermosetting materials. It applies where reinforcement fibres are discontinuous with a pre‑processing length > 7.5 mm or continuous (e.g., fabrics, mats, unidirectional reinforcements). The standard aims to make material data sheets consistent and directly comparable across suppliers and test laboratories.

Key topics and technical requirements

• Scope and purpose: Specifies which basic, single‑point properties are to be reported and why standardization is needed for valid comparison of materials.
• Specimen preparation and conditioning: Requires defined procedures for producing test specimens and conditioning them to standard atmospheres to ensure consistency.
• Test requirements: Identifies specific test methods to be used (referencing international and IEC/ISO test standards) rather than prescribing a single specimen geometry, acknowledging the anisotropic behaviour of long‑fibre composites.
• Presentation of results: Defines how single‑point values and, where applicable, paired values (different directions or conditions) should be recorded and reported so they are comparable on manufacturer data sheets.
• Acknowledgement of anisotropy: For properties that vary with fibre orientation, the standard specifies using the appropriate procedure for the reinforcement type and direction to ensure meaningful property values.

Relevant referenced test standards include tensile (ISO 527 series), flexural (ISO 14125), impact (ISO 179 / ISO 6603-2), thermal (ISO 11357, ISO 11359, ISO 75-3), density and content (ISO 1183, ISO 1172, ISO 14127), electrical and flammability (IEC/ISO references), and conditioning (ISO 291).

Applications and who uses it

• Material manufacturers: Produce consistent, comparable data sheets for long‑fibre‑reinforced plastics.
• Design and application engineers: Compare candidate materials during initial selection and design tradeoffs.
• Testing laboratories: Implement harmonized procedures to generate single‑point property data.
• Procurement and OEMs: Use standardized data to evaluate suppliers and materials for components in automotive, aerospace, electrical, and industrial applications.
• Standards bodies and specifiers: Reference for regulatory, procurement, and compliance documentation.
