(Main)Plastics - Ethylene/vinyl alcohol (EVOH) copolymer moulding and extrusion materials - Part 1: Designation system and basis for specifications (ISO 21309-1:2019)
General Information
- Abstract
This document establishes a system of designation for ethylene/vinyl alcohol (EVOH) copolymer thermoplastic materials, which may be used as the basis for specifications.
The types of ethylene/vinyl alcohol (EVOH) copolymer plastic are differentiated from each other by a classification system based on appropriate levels of the designatory property:
— melt mass-flow rate;
— and on information about basic polymer parameters, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.
This document is applicable to copolymers of ethylene and vinyl alcohol containing from 15 mol % to 60 mol % of ethylene. It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colorants, additives, fillers, etc.
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 can be required to specify a material for a particular application and/or method of processing.
If such additional properties are required, they are intended to be determined in accordance with the test methods described ISO 21309-2, if suitable.
In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements can be given in data block 4 and 5 (see Clause 4, introductory paragraph).

Overview
EN ISO 21309-1:2019 - Plastics - Ethylene/vinyl alcohol (EVOH) copolymer moulding and extrusion materials - Part 1: Designation system and basis for specifications - establishes a standardized labeling and classification system for EVOH thermoplastic materials. It applies to ethylene/vinyl alcohol copolymers containing 15 mol % to 60 mol % ethylene, in forms ready for use (powder, granules or pellets), unmodified or modified by colourants, additives, fillers or reinforcements. The document defines how to record composition, processing intent and key designatory properties (notably melt mass‑flow rate) as the basis for material specifications.
Key topics and technical requirements
- Designation structure: A standardized pattern with an identity block and an individual-item block subdivided into five data blocks (Data blocks 1–5). The individual-item block begins with a hyphen and data blocks are comma-separated.
- Data block 1 (composition): Identifies the polymer symbol EVOH (per ISO 1043-1) plus a two‑figure code number indicating ethylene content (mol %) using specified ranges (e.g., code 15 = >13–≤17 mol %; code 58 = >55–≤60 mol % - full table in the standard).
- Data block 2 (fillers/reinforcements): Reserved for filler or reinforcement type and typical content (not normally used for EVOH).
- Data block 3 (application/processing & modifiers): Position 1 = intended application or method of processing (letters for extrusion, moulding, films, etc.); positions 2–8 = important properties, additives and colour (e.g., “G” for granules, “C” for coloured).
- Data block 4 (designatory property - MFR): Melt mass‑flow rate (MFR) encoded as a code-letter (test conditions) plus a three‑figure code for the MFR range. MFR is measured per ISO 1133-1 using set X (210 °C, 2.16 kg); set D (190 °C, 2.16 kg) can be used for comparisons with some polymers.
- Data block 5 (additional specification data): Optional block for extra requirements needed in contractual specifications.
- Important note: a common designation does not guarantee identical performance-engineering, performance and processing data are outside Part 1.
Applications and who uses it
- Intended for material suppliers, polymer compounders, product designers, specifiers, purchasing and quality engineers who need a consistent designation system for EVOH.
- Useful when preparing material specifications for moulding and extrusion procurement, regulatory submissions, supplier declarations and production traceability.
- Particularly relevant in industries specifying barrier or specialty copolymers where EVOH composition and processability must be clearly communicated.

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
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
