Plastics - Ultra-high-molecular-weight polyethylene (PE-UHMW) moulding and extrusion materials - Part 1: Designation system and basis for specifications
This document establishes a system of designation for thermoplastic PE-UHMW materials, which can be used as the basis for specifications. For the purposes of this document, PE-UHMW materials are polyethylene materials having a melt mass-flow rate (MFR) of less than 0,1 g/10 min, measured at 190 °C and 21,6 kg load. NOTE It has been confirmed that the melt volume-flow rate (MVR) is useful for characterizing some PE-UHMW materials (e.g. pipe materials) under the test condition of 230 °C/21,6 kg and bore diameter of die with 3,628 mm (see ISO 21304-2). The types of PE-UHMW are differentiated from each other by a classification system based on appropriate levels of the designatory properties: a) viscosity number; b) elongational stress; c) Charpy double-notched impact strength; and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. This designation system is applicable to all PE-UHMW homopolymers and to ultra-high-molecular-weight copolymers of ethylene having a content of other 1-olefinic monomers of less than 50 % by mass and a content of non-olefinic monomers with functional groups up to a maximum of 3 % by mass. It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colorants, fillers and other additives. 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. If such additional properties are required, they are intended to be determined in accordance with the test methods specified in ISO 21304-2, if suitable. In order to specify a thermoplastic PE-UHMW material to meet particular specifications, the requirements are to be given in data block 5 (see 4.1).

Overview
ISO 21304-1:2019 defines a standardized designation system and the basis for specifications for ultra-high-molecular-weight polyethylene (PE‑UHMW) moulding and extrusion materials. It applies to PE‑UHMW with a melt mass‑flow rate (MFR) < 0.1 g/10 min (190 °C, 21.6 kg) and covers homopolymers and selected copolymers supplied as powder, granules or pellets. The standard provides a concise code-based format for identifying material type, fillers, intended application/processing, key designatory properties and optional specification requirements.
Key topics and requirements
- Designation structure (individual-item block): Five comma‑separated data blocks following the identity block:
- Data block 1: Identification symbol “PE‑UHMW” (per ISO 1043‑1).
- Data block 2: Filler/reinforcement type, form and nominal content using code letters and numeric content.
- Data block 3: Intended application/method of processing (position 1) and up to seven positions for properties, additives and colour.
- Data block 4: Three designatory properties coded by ranges:
- Viscosity number (determined per ISO 1628‑3, nitrogen atmosphere) coded into seven ranges.
- Elongational stress (determined per ISO 21304‑2, Annex B) coded into six ranges.
- Charpy double‑notched impact strength (per ISO 21304‑2, Annex C) coded into five ranges.
- Data block 5 (optional): Additional requirements to transform a designation into a formal specification (e.g., reference to national standards).
- Format rules: Hyphen starts the individual-item block; data blocks separated by commas; empty blocks shown by consecutive commas.
- Scope limits & notes: MVR can be useful for characterizing some PE‑UHMW (see ISO 21304‑2); identical designations do not guarantee identical performance - test data or additional specifications may be needed.
Applications and who uses it
ISO 21304‑1 is intended for:
- Material manufacturers and compounders to label and market PE‑UHMW grades.
- Product designers and OEMs to identify candidate materials for moulding, extrusion, pipes, films, fibres and sintering.
- Procurement and quality engineers to create unambiguous purchase specifications and quality acceptance criteria.
- Standards writers and testing labs as a basis for consistent specification and communication of PE‑UHMW properties.
Practical benefits include streamlined grade selection, clearer supplier communication, and a standardized starting point for application‑specific material specifications.
Related standards
- ISO 21304‑2: Test specimen preparation and determination of properties (referenced for elongational stress, Charpy tests and MVR guidance).
- ISO 1043‑1: Symbols and abbreviated terms for plastics (used for the PE‑UHMW symbol).

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).

Thermoplastic materials.
This first edition of ISO 21304-1 cancels and replaces ISO 11542-1:2001, which has been technically
revised to introduce a new designation system.
The revised designation system is published under a new ISO number, as many existing documents
refer to ISO 11542-1. If the existing ISO 11542-1 would be replaced by the new designation system,
these documents would refer to the incorrect designation system.
The new designation system according to ISO 21304-1 is intended to replace gradually any designation
system according to ISO 11542-1.
During this period, ISO 11542-2 will effectively be Part 2 of this document.

3,628 mm (see ISO 21304-2).
The types of PE-UHMW are differentiated from each other by a classification system based on
appropriate levels of the designatory properties:
a) viscosity number;
b) elongational stress;
c) Charpy double-notched impact strength;
and on information about the intended application and/or method of processing, important properties,
additives, colorants, fillers and reinforcing materials.
This designation system is applicable to all PE-UHMW homopolymers and to ultra-high-molecular-
weight copolymers of ethylene having a content of other 1-olefinic monomers of less than 50 % by mass
and a content of non-olefinic monomers with functional groups up to a maximum of 3 % by mass. It
applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or
modified by colorants, fillers and other additives.
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. If such additional properties are required, they
are intended to be determined in accordance with the test methods specified in ISO 21304-2, if suitable.

Système de désignation et base de spécifications
1 Domaine d’application
Le présent document établit un système de désignation des matériaux thermoplastiques en PE-UHMW
qui peut être utilisé comme base pour les spécifications.
Pour les besoins du présent document, les matériaux en PE-UHMW sont des matériaux en polyéthylène
ayant un indice de fluidité à chaud en masse (MFR) inférieur à 0,1 g/10 min, mesuré à 190 °C et avec une
charge de 21,6 kg.
NOTE Il a été confirmé que l’indice de fluidité à chaud en volume (MVR) est utile pour caractériser certains
matériaux PE-UHMW (par exemple des matériaux pour tubes) dans des conditions d'essai de 230 °C/21,6 kg et
un diamètre de filière de 3,628 mm (voir l’ISO 21304-2).
Les types de PE-UHMW sont différenciés les uns des autres par un système de classification fondé sur
des niveaux appropriés des propriétés de désignation:
a) indice de viscosité;
b) contrainte d’allongement;
c) résistance au choc Charpy avec double entaille;
et des informations sur l’application prévue et/ou la méthode de mise en œuvre, les propriétés
importantes, les additifs, les colorants, les charges et les matériaux de renfort.
Le présent système de désignation est applicable à tous les homopolymères du PE-UHMW et aux
copolymères éthyléniques à très haute masse moléculaire ayant une teneur en autres monomères
1-oléfiniques inférieure à 50 % en masse et une teneur maximale en monomères non oléfiniques avec
des groupes fonctionnels ne dépassant pas 3 % en masse. Il s’applique aux matériaux prêts à l’emploi
dans le cadre d’une utilisation normale sous la forme de poudre, granulés ou grains et aux matériaux
non modifiés ou modifiés par des colorants, charges et autres additifs.
Le fait que des matériaux aient la même désignation n’implique pas qu’ils présentent nécessairement
les mêmes performances. Le présent document ne comporte pas de données sur la conception, la
performance ou les conditions de mise en œuvre qui peuvent être exigées pour spécifier un matériau.
Si de telles caractéristiques supplémentaires sont nécessaires, elles doivent être déterminées
conformément aux méthodes d’essai spécifiées dans l’ISO 21304-2, s’il y a lieu.
Afin de spécifier un matériau thermoplastique en PE-UHMW pour répondre à une spécification
particulière, les exigences doivent être codées dans le bloc de données 5 (voir 4.1).

제목: ISO 21304-1:2019 - 플라스틱 - 초고분자량 폴리에틸렌 (PE-UHMW) 성형 및 압출 재료 - 제1부: 지정 시스템 및 규격 기준 내용: 본 문서는 규격의 기반으로 사용될 수 있는 열가소성 PE-UHMW 재료의 지정 시스템을 수립한다. 본 문서의 목적을 위해 PE-UHMW 재료는 190 °C에서 측정된 21.6 kg 하중하에서 0.1 g/10 min 이하의 용융 질량 흐름율(MFR)을 가지는 폴리에틸렌 재료로 정의된다. 참고로 일부 PE-UHMW 재료(예: 파이프 재료)의 경우 230 °C/21.6 kg 및 다이 내경 3.628 mm의 시험 조건에서 용융 체적 유량(MVR)이 유용하다는 것이 확인되었다(ISO 21304-2 참조). PE-UHMW의 유형은 지정 속성의 적절한 수준을 기반으로 한 분류 체계를 통해 서로 구별된다: a) 점도 숫자; b) 연신장력; c) Charpy 이중 노치 충격강도; 그리고 응용 분야와/또는 가공 방법, 중요한 속성, 첨가제, 색소, 충전재 및 보강재에 대한 정보에 따라 구분된다. 이 지정 시스템은 PE-UHMW 단일중합체와 에틸렌의 1-올레핀 단량체의 함량이 질량에 대해 50 % 미만이며 기능성 그룹을 갖지 않는 비올레핀 단량체의 함량이 최대 3 % 이내인 초고분자량 공중합체까지 적용된다. 이는 가공이나 미가공 상태의 분말, 곡물 또는 펠릿 형태로 일반적인 사용을 위해 준비된 재료에 적용된다. 이 문서는 동일한 지정이 반드시 동일한 성능을 제공한다는 것을 의미하는 것은 아니다. 이 문서는 재료를 지정하기 위해 필요한 공학 데이터, 성능 데이터 또는 가공 조건 데이터를 제공하지 않는다. 해당 추가 속성이 필요한 경우, 적합하다면 ISO 21304-2에 명시된 시험 방법에 따라 결정되어야 한다. 특정 규격을 충족시키기 위해 열가소성 PE-UHMW 재료를 지정하기 위해 요구사항은 데이터 블록 5에 제공되어야 한다.
The article discusses ISO 21304-1:2019, which establishes a system for designating thermoplastic ultra-high-molecular-weight polyethylene (PE-UHMW) materials. It specifies the properties of PE-UHMW materials, such as viscosity number, elongational stress, and Charpy double-notched impact strength. The designation system applies to PE-UHMW homopolymers and certain types of copolymers. The document also states that materials with the same designation may not have identical performance. It does not provide engineering or performance data, but additional properties can be determined using test methods specified in ISO 21304-2.

記事のタイトル:ISO 21304-1:2019-プラスチック-超高分子量ポリエチレン(PE-UHMW)成形および押出材料-第1部:指定システムと仕様の基盤 記事の内容:この文書は、仕様の基盤となるために使用できる熱可塑性PE-UHMW材料の指定システムを確立します。この文書では、PE-UHMW材料とは、190℃で測定された21.6キログラムの負荷で0.1グラム/10分未満のメルトマスフローレート(MFR)を持つポリエチレン材料と定義されます。注意:一部のPE-UHMW材料(例:パイプ材料)は、230℃/21.6キログラムの試験条件での3.628ミリメートルのダイの内径でのメルトボリュームフローレート(MVR)が有用であることが確認されています(ISO 21304-2を参照)。PE-UHMWのタイプは、指定特性の適切なレベルに基づく分類システムによって区別されます。この指定システムは、PE-UHMWホモポリマーおよびエチレンの超高分子量の共重合体に適用され、質量基準で1-オレフィンモノマーの含有量が50%未満であり、最大3%までの非オレフィンモノマーの含有量を有する機能基を持つものです。これは、粉末、顆粒またはペレットの形で通常使用の準備ができた材料に適用され、着色剤、充填剤、および他の添加物によって修飾または修飾されないものです。同じ指定を持つ材料が必ずしも同じ性能を持つことを意味するものではありません。この文書は、材料を指定するために必要なエンジニアリングデータ、性能データ、および加工条件のデータを提供しません。このような追加の特性が必要な場合は、適切な場合はISO 21304-2で指定された試験方法に従って決定することが意図されています。特定の仕様に合致する熱可塑性PE-UHMW材料を指定するためには、要件をデータブロック5に記載する必要があります(4.1を参照)。
The article is about ISO 21304-1:2019, which establishes a system of designation for ultra-high-molecular-weight polyethylene (PE-UHMW) materials. The designation system is based on properties such as viscosity number, elongational stress, and Charpy double-notched impact strength, as well as information about intended application, processing method, additives, colorants, fillers, and reinforcing materials. The designation system applies to all PE-UHMW materials, including homopolymers and copolymers, and materials ready for use in the form of powder, granules, or pellets. The article also clarifies that materials with the same designation may not necessarily have the same performance and that additional properties must be determined using the test methods specified in ISO 21304-2. Requirements for specifying a PE-UHMW material are to be given in data block 5.
