ISO 15015:2025

Overview

ISO 15015:2025 specifies requirements and test methods for solid flat extruded sheets made from impact‑modified acrylonitrile‑styrene copolymers - specifically ABS, AEPDS (AES) and ASA. The standard covers sheets (including rolled form) without fillers or reinforcement and applies to thicknesses from 0.25 mm to 20.0 mm. ISO 15015:2025 is the third edition and updates the 2011 version, consolidating appearance, dimensional, mechanical and thermal requirements with referenced test procedures.

Key topics and technical requirements

• Material scope: Extrusion materials conforming to ISO 19062‑1 (ABS) or ISO 19065‑1 (AEPDS/A S A). Additives (stabilizers, colorants, flame retardants) are permitted, but unknown compounds are not.
• Appearance: Sheets must be substantially free from bubbles, voids, cracks, visible impurities and surface defects; colorants should be uniformly dispersed.
• Dimensional tolerances:
  • Thickness range covered: 0.25–20.0 mm.
  • Thickness variation limit given by formula |Δh| ≤ (0.03 + 0.04 × h) (h in mm).
  • Length, width and rectangularity tolerances specified; special provisions for rolled sheets (bow limits).
• Mechanical and thermal properties: Requirements and guide values for tensile behavior, modulus, Charpy impact (notched and unnotched), ball indentation hardness, melt mass‑flow rate (MFR), Vicat softening temperature and shrinkage on heating.
• Test methods and test conditions: Detailed procedures for specimen preparation, conditioning and testing - referencing established methods for Charpy (ISO 179‑1/2), tensile (ISO 527‑2), MFR (ISO 1133‑1), Vicat (ISO 306), density (ISO 1183), hardness (ISO 2039‑1) and dimensional change (ISO 11501).
• Delivery, designation and marking: Requirements for delivery condition, labelling and designation examples for ABS/ASA sheets.

Practical applications

ISO 15015:2025 is intended to ensure consistent performance and quality of extruded ABS/AEPDS/ASA sheets used where impact resistance, dimensional stability and surface finish matter. Typical uses include:

• Decorative and protective panels, cladding and signage
• Appliance housings and trim components
• Transport interiors and non‑structural parts
• Prototyping and fabrication of thermoplastic sheet components

Using the standard helps manufacturers, quality labs and specifiers verify material conformity, select appropriate grades, and reduce variability in production and acceptance testing.

Who uses this standard

• Sheet extruders and compounders
• Material suppliers and distributors
• Quality assurance and testing laboratories
• Product designers, specifiers and procurement teams
• Converters and fabricators working with thermoplastic sheeting
