(Main)Plastics - Poly(methyl methacrylate) (PMMA) moulding and extrusion materials - Part 1: Designation system and basis for specifications (ISO 24026-1:2020)
General Information
- Abstract
This document establishes a system of designation for poly(methyl methacrylate) (PMMA) thermoplastic material, which can be used as the basis for specifications.
The types of PMMA plastic are differentiated from each other by a classification system based on appropriate levels of the designatory properties:
a) Vicat softening temperature;
b) melt mass-flow rate;
c) viscosity number (optional);
and on information about the intended application and/or method of processing, important properties, additives and colorants.
This document is applicable to all poly(methyl methacrylate) homopolymers and to copolymers of methyl methacrylate (MMA) containing at least a mass percentage of 80 % of MMA and not more than a mass percentage of 20 % of acrylic esters or other monomers.
This document applies to materials ready for normal use in the form of beads, granules and pellets and to materials unmodified or modified by colorants, additives, etc. It does not apply to PMMA modified with elastomers.
It is not intended to imply that materials having the same designation give necessarily the same performance. This document does not provide engineering data, performance data or data on processing conditions which might be required to specify a material for a particular application and/or method of processing.
If such additional properties are required, they are, if suitable, determined using the test methods specified in ISO 24026-2.
In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements can be given in data block 5 (see 4.1).

Overview
EN ISO 24026-1:2020 - Plastics - Poly(methyl methacrylate) (PMMA) moulding and extrusion materials - Part 1: Designation system and basis for specifications (CEN/ISO) defines a standardized system to designate PMMA thermoplastic materials. The standard establishes how PMMA grades are identified and described so they can form the basis of material specifications used across manufacturing, procurement and testing.
Key topics and requirements
- Scope and applicability
- Applies to PMMA homopolymers and MMA copolymers containing ≥80 % MMA (≤20 % other monomers); for materials in beads, granules and pellets.
- Excludes PMMA modified with elastomers.
- Designation structure
- A standard pattern: identity block (ISO number + symbol) and an individual-item block subdivided into five data blocks.
- Data block 1: Identification by the polymer symbol PMMA (ISO 1043-1).
- Data block 2: (Reserved for fillers/reinforcements - not used in this part).
- Data block 3: Intended application / processing method (position 1) and important properties/additives/colorants (positions 2–8). Examples of codes include:
- M = injection moulding, E = extrusion, D = disc manufacture
- C = coloured, N = natural, L = light/weather stabilized, T = controlled transparency, Z = antistatic
- Data block 4: Encoded designatory properties:
- Vicat softening temperature - three-figure code
- Melt mass-flow rate (MFR) - three-figure code
- Viscosity number (optional) - two-figure code
These properties are determined using test methods in ISO 24026-2.
- Data block 5: Optional additional requirements for alternative specifications or special applications.
- Limitations
- The standard does not provide performance, engineering or processing data. Materials sharing the same designation may still differ in performance; supplementary tests/specifications are recommended when needed.
Applications and users
- Useful for:
- Material specifiers and design engineers preparing PMMA material specifications.
- Polymer producers, compounders and suppliers to communicate grade identity.
- Moulders and extruders, procurement teams and quality-control laboratories for consistent grade identification and traceability.
- Standards committees and testing labs aligning test methods and specification frameworks.
- Practical uses:
- Creating unambiguous PMMA grade descriptions for contracts and purchase orders.
- Baseline classification for product development, quality control and regulatory documentation.
- Streamlining supplier communications across the supply chain.
Related standards

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
