1.1 In diesem Teil von ISO 1872 wird ein Bezeichnungssystem fu(r thermoplastiche Polyethylen (PE)-Formmassen festgelegt, das als Grundlage fu(r Spezifikationen dienen kann. 1.2 PE-Formmassen-Typen werden mit Hilfe eines Einleitungssystems voneinander unterschieden, das auf geeigneten Wertebereichen der kennzeichnenden Eigenschaften a) Dichte; b) Schmelze-Massefließrate (MFR) und Informationen u(ber vorgesehene Anwendung und/oder Verarbeitungsverfahren, wichtige Eigenschaften, Additive, Farbstoffe, Fu(ll- und Versta(rkungsstoffe beruht.
Plastiques - Polyéthylène (PE) pour moulage et extrusion - Partie 1: Système de désignation et base de spécification (ISO 1872-1:1993)
La présente partie de l'ISO 1872 établit un système de désignation des matériaux thermoplastiques polyéthylène qui peut être utilisé comme base pour les spécifications. Les types de plastiques polyéthylène sont différenciés les uns des autres par un système de classification basé sur des niveaux appropriés des propriétés de désignation a) masse volumique b) indice de fluidité à chaud en masse et des informations concernant l'application prévue et/ou la méthode de mise en ceuvre, les propriétés importantes, les additifs, colorants, matériaux de charge et renfort. La présente partie de l'ISO 1872 est applicable à tous les homopolymères polyéthylène et aux copolymères de l'éthylène ayant une teneur en autres monomères 1-oléfiniques inférieure à 50 % (m/m) et une teneur maximale de 3 % (m/m) en monomères non oléfiniques ayant des groupes fonctionnels. Elle s'applique aux matériaux prêts à l'emploi sous forme de poudres, grains ou granulés, non modifiés ou modifiés par des colorants, additifs, charges, etc. La présente partie de l'ISO 1872 ne s'applique ni aux mélanges-maîtres, ni au caoutchouc EPM. Le fait que des matériaux aient la même désignation n'implique pas qu'ils présentent nécessairement les mêmes performances. La présente partie de l'ISO 1872 ne comporte pas de données sur la conception, la performance ou les conditions de mise en oeuvre qui peuvent être exigées pour spécifier un matériau pour une application et/ou une méthode de mise en oeuvre particulière. Si de telles caractéristiques additionnelles sont nécessaires, elles doivent être déterminées conformément aux méthodes d'essai prescrites dans l'ISO 1872-2, si appropriée. Afin de prescrire un matériau thermoplastique pour une application particulière ou d'assurer une méthode de mise en oeuvre reproductible, des exigences additionnelles peuvent être codées dans le bloc de données 5 (voir article 3, alinéas d'introduction).

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
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. IS0
collaborates closely with the International Electrotechnical Commission
(I EC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 1872-1 was prepared by Technical Committee
lSO/TC 61, Plastics, Sub-Committee SC 9, Thermoplastic materials.
This second edition cancels and replaces the first edition
(IS0 1872-l :1986), which has been brought into accordance with the re-
vised frame text for designation standards.
IS0 1872 consists of the following parts, under the general title
P/as tics - Polyethylene (PE) moulding and extrusion materials:
- Part I: Designation system and basis for specifications
- Part 2: Preparation of test specimens and determination of proper-

Part I:
Designation system and basis for specifications
1 Scope
1.1 This part of IS0 1872 establishes a system of designation for polyethylene thermoplastic material, which
may be used as the basis for specifications.
1.2 The types of polyethylene plastic are differentiated from each other by a classification system based on ap-
propriate levels of the designatory properties
a) density
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 part of IS0 1872 is applicable to all polyethylene homopolymers and to copolymers of ethylene having
a content of other I-olefinic monomers of less than 50 % (m/m) and a content of non-olefinic monomers with
functional groups up to a maximum of 3 % (m/m).
It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by
colorants, additives, fillers, etc.
This part of IS0 1872 does not apply to masterbatches or to EPM rubber.
1.4 It is not intended to imply that materials having the same designation give necessarily the same perform-
ance. This part of IS0 1872 does not provide engineering data, performance data or data on processing conditions
which may be required to specify a material for a particular application and/or method of processing.
If such additional properties are required, they shall be determined in accordance with the test methods specified
in part 2 of this International Standard, if suitable.
1.5 In order to specify a thermoplastic material for a particular application or to ensure reproducible processing,
additional requirements may be given in data block 5 (see clause 3, introductory paragraph).

3 Designation and specification system
The designation and specification system for thermoplastics is based on the following standardized pattern:
Designation
Identity block
Description block Individual-item block
(optional)
International Stan-
dard number block
Data block Data block Data block Data block
Data block

,
The designation consists of an optional description block, reading “Thermoplastics”, and an identity block com-
prising the International Standard number and an individual-item block. For unambiguous designation, the
individual-item block is subdivided into five data blocks comprising the following information:
Data block 1: Identification of the plastic by its symbol PE in accordance with IS0 1043-l (see 3.1).
Data block 2: Position 1: Intended application or method of processing (see 3.2).
Positions 2 to 8: Important properties, additives and supplementary information (see 3.2).
Data block 3: Designatory properties (see 3.3).
Data block 4: Fillers or reinforcing materials and their nominal content (see 3.4).
Data block 5: For the purpose of specifications, a fifth data block may be added containing additional infor-
mation.
The first character of the individual-item block shall be a hyphen. The data blocks shall be separated from each
other by commas.
If a data block is not used, this shall be indicated by doubling the separation sign, i.e. by two commas (,,L
3.1 Data block 1
In this data block, after the hyphen, polyethylene plastics are identified by the symbol “PE”, in accordance with
IS0 1043-I.
IS0 1872=1:1993(E)
3.2 Data block 2
In this data block, information about the intended application and/or method of processing is given in position 1
and information about important properties, additives and colour in positions 2 to 8. The code-letters used are
specified in table 1.
If information is presented in positions 2 to 8 and no specific informa
