Overview
EN ISO 19066-1:2014 - Plastics: MABS moulding and extrusion materials (Part 1) defines a standardized designation system and the basis for specifications for methyl methacrylate‑acrylonitrile‑butadiene‑styrene (MABS). The standard applies to MABS materials in powder, granule or pellet form (unmodified or with colorants, additives, fillers or reinforcements) intended for moulding and extrusion. EN ISO 19066-1:2014 replaces and simplifies the previous ISO 10366-1 system and aligns identification more closely with ISO 1043 and ISO 11469.
Key topics and requirements
- Designation structure: a standardized identity block plus an individual‑item block subdivided into five data blocks (1–5). The individual item starts with a hyphen and data blocks are comma‑separated; unused blocks are indicated by two commas (,,).
- Data block 1 - Composition: identifies the polymer as MABS (ISO 1043‑1) and adds a single code letter (A–D) that indicates the ranges of acrylonitrile (AN) and methyl methacrylate (MMA) content.
- Data block 2 - Fillers and reinforcements: codes for filler/reinforcing material type and form (per ISO 1043‑2) and nominal mass content (e.g., GF25 for 25 % glass fibre). Mixed fillers use “( … )” notation with total content.
- Data block 3 - Application/processing and additives: codes for intended application or processing method (position 1) and positions 2–8 for important properties, additives or supplementary information.
- Data block 4 - Designatory properties: classification levels for the critical designatory properties used to differentiate MABS types:
- Vicat softening temperature
- Melt volume‑flow rate (MVR)
- Charpy notched impact strength
- Tensile modulus
- Data block 5 - Additional specification data: optional details for contractual specifications or manufacturing requirements.
- Limitations: the standard provides a designation and classification basis but does not supply engineering performance data or processing conditions; additional properties or test methods are to be determined per ISO 10366‑2 where applicable.
Applications and users
EN ISO 19066-1:2014 is used by:
- Material suppliers and compounders for consistent product identification and data sheets
- Designers and product engineers specifying MABS for parts made by injection moulding or extrusion
- Purchasing and quality management teams to define contract specifications
- Test laboratories and certification bodies for material classification and traceability
- Standards committees and regulatory bodies harmonizing material marking and labelling
Practical benefits include clearer material communication across the supply chain, simplified marking in line with ISO 1043/11469, and a reproducible basis for creating technical specifications for MABS moulding and extrusion materials.
