Abstract

Overview

ISO 7823-3:2021 - Plastics - Poly(methyl methacrylate) sheets - Part 3: Continuous cast sheets - specifies requirements for non‑modified flat PMMA continuous cast sheets for general‑purpose use. It covers sheets that are colourless or coloured, and that may be transparent, translucent or opaque, with a thickness range of 1 mm to 10 mm. The standard defines composition limits, appearance criteria, dimensional tolerances, basic mechanical/thermal/optical properties and relevant test methods for quality and conformity.

Key Topics and Requirements

Scope and composition
- Applies to PMMA bulk‑polymerized (continuous cast) homopolymers or copolymers.
- Additives (colorants, UV absorbers, etc.) are permitted; amounts that affect basic properties are typically less than 5 % by mass.
Appearance and surface quality
- Smooth surfaces required; no surface defects or inclusions larger than 3 mm.
- Defects are classified: negligible (
