ISO 7823-2:2003 specifies requirements for flat poly(methyl methacrylate) (PMMA) sheets extruded from colourless or coloured, transparent, translucent or opaque materials. The thickness range of the sheets covered by this part of ISO 7823 is 1,5 mm to 20 mm.

Abstract

Overview

EN ISO 7823-2:2003 (ISO 7823-2:2003) specifies requirements for flat poly(methyl methacrylate) (PMMA) extruded sheets. It covers sheets made from colourless or coloured, transparent, translucent or opaque PMMA and applies to thicknesses from 1.5 mm to 20 mm. The standard defines appearance, dimensional tolerances, surface and inclusion defect limits, protective coverings, and test methods (with normative references) to ensure consistent quality of extruded PMMA sheet products.

Key topics and technical requirements

Scope and sheet types: Flat PMMA extruded sheets (homopolymers and copolymers of MMA with ≥80% MMA).
Thickness range: 1.5 mm to 20 mm.
Protective coverings: Surfaces should be delivered protected (eg. kraft paper or polyethylene film) and removable without surface damage.
Appearance and defects:
- Surface defects must not exceed 4 mm each.
- Inclusions (bubbles, foreign matter) must not exceed 2 mm each.
- Defect classification: negligible, acceptable (specific area thresholds provided in the standard).
- Distribution rules: limits on numbers and proximity of defects (e.g., acceptable defects must be at least 500 mm apart).
Dimensions and tolerances:
- Length/width tolerances for cut sheets (examples: up to 1 000 mm: +3/0 mm; 1 001–2 000 mm: +6/0 mm; 2 001–3 000 mm: +9/0 mm; ≥3 001 mm: +0.3%/0).
- Thickness tolerances: ±10% for 1.5–
