Overview
EN ISO 15015:2025 (ISO 15015:2025) is the CEN-adopted international standard for extruded sheets of impact‑modified acrylonitrile‑styrene copolymers - specifically ABS, AEPDS (AES) and ASA. It defines requirements and test methods for solid, flat extruded sheets (including sheets supplied in rolled form) without fillers or reinforcing materials. The standard applies to sheet thicknesses from 0.25 mm to 20.0 mm and supersedes the 2011 edition, providing an updated, harmonized specification for manufacturers, testers and users across Europe and internationally.
Key topics and requirements
EN ISO 15015:2025 covers technical and quality aspects essential for material selection and conformity testing:
- Scope and terminology - definitions for ABS, AEPDS/AES and ASA sheet products.
- Material requirements - limits on composition (no fillers/reinforcement) and delivery condition.
- Appearance and dimensional tolerances - visual quality, thickness, length, width, rectangularity, and bow (for rolled sheets).
- Mechanical properties and test methods:
- Tensile stress at yield and modulus of elasticity (tension)
- Charpy impact strength (notched and unnotched)
- Ball indentation hardness
- Melt mass‑flow rate (MFR)
- Thermal properties and tests:
- Vicat softening temperature
- Shrinkage on heating
- Physical tests - density and specimen preparation, conditioning, and standard test conditions.
- Designation and marking - how sheets should be identified and labelled for traceability.
- Test procedures and specimen preparation are specified to ensure reproducible results across laboratories.
Practical applications
This standard supports quality control, procurement and regulatory compliance in sectors that use extruded ABS/AEPDS/ASA sheets:
- Product designers and material engineers selecting impact‑modified styrenic sheets for housings, trims, signage, or decorative panels.
- Manufacturers ensuring consistent extrusion quality and batch conformity.
- Testing laboratories performing mechanical, thermal and dimensional verification.
- Procurement and conformity assessors creating specifications for suppliers and tender documents.
Who should use this standard
- Sheet extruders and compounders of ABS, AEPDS (AES) and ASA
- Quality assurance teams and R&D groups in plastics manufacturing
- Independent testing laboratories and certification bodies
- Specifiers in automotive, appliance, building products, and consumer goods industries
Related standards
- ISO 15015:2025 is aligned with CEN adoption (EN ISO 15015:2025) and references other normative documents (e.g., ISO 291 for dimensional tolerances where applicable). Users should consult referenced ISO/CEN documents and national implementations for full requirements and regulatory context.
