ISO 7823-1:2003 specifies requirements for non-modified flat poly(methyl methacrylate) (PMMA) cast sheets (plates) for general-purpose use. The sheets may be colourless or coloured, and may be transparent, translucent or opaque. The thickness range of the sheets covered by this part of ISO 7823 is 1,5 mm to 25 mm.

Overview

EN ISO 7823-1:2003 (CEN adoption of ISO 7823-1:2003) specifies requirements for non‑modified flat poly(methyl methacrylate) (PMMA) cast sheets for general‑purpose use. The standard covers cast (bulk‑polymerized) PMMA sheets that may be colourless or coloured and can be transparent, translucent or opaque. Applicable sheet thicknesses are 1.5 mm to 25 mm. This document is intended for manufacturers, buyers, test laboratories and specifiers who need consistent quality, dimensional tolerances and performance characteristics for PMMA cast sheets.

Key topics and technical requirements

Scope and definitions: Clarifies what is meant by non‑modified cast PMMA and flat sheets (two substantially parallel surfaces).

Composition limits: Allows additives (colourants, UV absorbers, etc.) but plasticizers, other monomers and crosslinking agents shall not alter basic properties beyond the values specified (amounts typically < 3 %).

Appearance and defects:

Sheets must be smooth; no scratches, marks or inclusion defects larger than 3 mm.
Defects are classified by area: negligible (<1 mm²), acceptable (1–3 mm²), or unacceptable (>3 mm²).
Limits on defect distribution (e.g. no significant number of negligible defects within 1 m; acceptable defects at least 500 mm apart) to control cosmetic quality.

Protective coverings: Surfaces as delivered should be protected (kraft paper, polyethylene film) removable without damage.

Dimensional tolerances:

Length/width tolerances for cut sheets are specified by ranges (e.g., 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 tolerance for 1.5–25 mm sheets: ± (0.4 mm + 0.1 h), where h is nominal thickness in mm.

Referenced test methods: Normative references include ISO methods for water absorption, tensile and flexural properties, impact (Charpy), refractive index, luminous transmittance and haze, and specimen preparation.

Applications and users

Who uses it: PMMA sheet manufacturers, quality control and testing laboratories, fabricators, procurement/specification teams, architects and product designers who require standardized material properties and acceptance criteria.

Typical applications: Architectural glazing, signage and display panels, lighting diffusers, point‑of‑sale fixtures and decorative components where optical clarity, surface quality and predictable dimensions matter.
