Abstract

Overview

ISO 7823-2:2003 is the International Standard that specifies requirements for flat poly(methyl methacrylate) (PMMA) extruded sheets (acrylic sheets). It covers colourless or coloured, transparent, translucent or opaque extruded PMMA sheets with a thickness range of 1.5 mm to 20 mm. The standard defines appearance, dimensional tolerances, basic mechanical, thermal and optical properties, protective coverings, sampling and test methods for quality control.

Key topics and technical requirements

Scope and sheet types: Applies to extruded PMMA homopolymers and copolymers (≥80% MMA) used as flat sheets.
Protective coverings: Surfaces as delivered shall be protected by removable films or paper to avoid contamination or damage.
Appearance and defects:
- Smooth surface required; no surface defects larger than 4 mm.
- No inclusions larger than 2 mm; defect classification and acceptable distributions are defined.
Dimensions and tolerances:
- Length/width tolerances for cut sheets are specified by size ranges (e.g., up to 1 000 mm: +3/0 mm; 1 001–2 000 mm: +6/0 mm; etc.).
- Thickness tolerances: ±10% for 1.5–
