Plastics - Ethylene-vinyl acetate (EVAC) moulding and extrusion materials - Part 1: Designation system and basis for specifications (ISO 21301-1:2019)

1.1    This document establishes a system of designation for ethylene-vinyl acetate thermoplastic material, which can be used as the basis for specifications.
1.2    The types of ethylene-vinyl acetate (EVAC) plastic are differentiated from each other by a classification system based on appropriate levels of the following designatory properties:
a)    vinyl acetate content;
b)    melt mass-flow rate;
and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.
1.3    This document is applicable to all ethylene vinyl acetate copolymers containing from a mass fraction from 3 % to 50 % (approximately 25 % molar) of vinyl acetate.
It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc.
1.4    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 determined in accordance with the test methods specified in ISO 21301-2, if suitable.
1.5    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).

1.3 Ta dokument se uporablja za vse kopolimere etilen/vinilacetata, katerih masni delež vinilacetata je 3–50 % (približno 25 % molarnega).
Uporablja se za materiale v obliki praška, granul ali peletov, pripravljene za običajno uporabo, in materiale, nespremenjene ali spremenjene z barvili, aditivi, polnili itd.
1.4 Materiali z enako oznako nimajo nujno tudi enakih
lastnosti. Ta dokument ne podaja tehničnih podatkov, podatkov o delovanju ali podatkov o pogojih obdelave, ki so morda potrebni za določitev materiala za določeno uporabo in/ali metodo obdelave.
Če so take dodatne lastnosti zahtevane, jih je treba določiti v skladu s preskusnimi metodami
iz standarda ISO 21301-2, če je to primerno.
1.5 Zahteve za določanje plastomernega materiala za določeno uporabo ali zagotavljanje ponovljive

Overview

EN ISO 21301-1:2019 - Plastics - Ethylene‑vinyl acetate (EVAC) moulding and extrusion materials - Part 1: Designation system and basis for specifications (CEN adoption of ISO 21301-1:2019) defines a standardized system to identify and classify ethylene‑vinyl acetate (EVAC) thermoplastic materials. It provides a clear, machine‑readable designation format that can be used as the basis for material specifications, product marking and procurement, for EVAC copolymers containing 3 % to 50 % (mass fraction) vinyl acetate in powder, granule or pellet form (including materials modified with colorants, additives, fillers or reinforcing materials).

Key topics

• Designation system structure: identity block (standard number) + individual‑item block subdivided into five data blocks (1–5). The individual‑item block begins with a hyphen and data blocks are separated by commas.
• Data block 1 - EVAC identification and vinyl acetate (VAC) content: EVAC symbol (per ISO 1043‑1) followed by VAC content code. VAC ranges are encoded into eight two‑digit code numbers:
  • 03: >3 % ≤5 %
  • 08: >5 % ≤10 %
  • 13: >10 % ≤15 %
  • 18: >15 % ≤20 %
  • 23: >20 % ≤25 %
  • 28: >25 % ≤30 %
  • 35: >30 % ≤40 %
  • 45: >40 % ≤50 %
• Data block 2: filler/reinforcement type and physical form (ISO 1043‑2 codes) and nominal mass content.
• Data block 3: intended application or processing method plus important properties, additives and supplementary information.
• Data block 4: designatory properties such as melt mass‑flow rate (MFR) and other key classification parameters.
• Data block 5: optional block for additional specification requirements to ensure reproducible processing or performance.
• Limits of the standard: EN ISO 21301‑1:2019 does not supply engineering performance data or processing conditions. Where test data are required, refer to ISO 21301‑2.

Applications

• Standardized material identification for technical data sheets, product marking and inventory.
• Basis for drafting material specifications in procurement and supply agreements.
• Communication between material producers, compounders, moulders and extruders to reduce ambiguity in EVAC selection.
• Quality control, regulatory documentation and traceability in manufacturing of footwear, packaging, wire & cable, adhesives, seals, automotive and consumer goods that use EVAC.

Who should use this standard

• Material suppliers and compounders
• Product designers and R&D engineers specifying EVAC materials
• Quality assurance and regulatory compliance teams
• Moulding and extrusion processors, procurement specialists

Related standards

• ISO 21301‑2 (test specimen preparation & property determination)
• ISO 1043‑1 and ISO 1043‑2 (polymer and filler symbol systems)
• ISO 8985 (determination of vinyl acetate content)
• Supersedes ISO 4613‑1 (older designation system)

Using EN ISO 21301‑1:2019 ensures consistent, unambiguous EVAC identification and forms a practical foundation for material specification, procurement and communication across the plastics value chain.

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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).

This first edition of ISO 21301-1 cancels and replaces the second edition of ISO 4613-1:1993, which has
been technically revised. The main changes compared to the previous edition are as follows:
— a new designation system has been introduced;
— the range of MFR has been added.
The revised designation system is published under a new ISO number, as many existing documents
refer to ISO 4613-1.
