Plastics - Polypropylene (PP) moulding and extrusion materials - Part 1: Designation system and basis for specifications (ISO 1873-1:1995)
Establishes a system of designation for polypropylene moulding and extrusion materials, which may be used as the basis for specifications. Polypropylenes are differentiated from each other by the levels of the designatory properties such as tensile modulus, impact strength and melt index includingly modifications by colorants, additives, fillers etc.. Cancels and replaces the third edition.
Kunststoffe - Polypropylen (PP) Formmassen - Teil 1: Bezeichnungssystem und Basis für Spezifikationen (ISO 1873-1:1995)
In diesem Teil von ISO 1873 wird ein Bezeichnungssytem für thermoplastische PP-Formmassen festgelegt, das als Grundlage für Spezifikationen dienen kann. PP-Formmasse-Typen werden mit Hilfe eines Einteilungssystems von einander unterschieden, das auf geeigneten Wertebereichen der kennzeichnenden Eigenschaften a) Zug-E-Modul; b) Schlagzähigkeit; c) Schmelze-Massenfließrate (MFR) und Informationen über grundlegende Polymer-Parameter, vorgesehene Anwendung und/oder Verarbeitungsverfahren, wichtige Eigenschaften, Additive, Farbstoffe, Füll- und Verstärkungsstoffe beruht.
Plastiques - Polypropylène (PP) pour moulage et extrusion - Partie 1: Système de désignation et base pour les spécifications (ISO 1873-1:1995)
1.1 La présente partie de l'ISO 1873 établit un système de désignation des matériaux thermoplastiques à base de polypropylène (PP) qui peut être utilisé comme base pour les spécifications. 1.2 Les types de plastiques polypropylène sont différenciés les uns des autres par un système de classification basé sur des niveaux appropriés des propriétés de désignation: a) module d'élasticité en traction b) résistance au choc c) indice de fluidité en masse (NFR) et sur des informations concernant certains paramètres du polymère de base, l'application prévue et/ou la méthode de mise en oeuvre, les propriétés importantes, les additifs, colorants, matériaux de charge et renfort. 1.3 La présente partie de l'ISO 1873 est applicable à tous les homopolymères et aux copolymères de propylène, ainsi qu'aux mélanges de polymères contenant au moins 50 % (m/m) de ces homopolymères et/ou copolymères. 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 1873 ne s'applique pas aux polymères du type élastomérique. 1.4 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 1873 ne comporte pas de données sur la concept 641ion, 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 1873-2, si appropriée. 1.5 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, alinéa d'introduction).

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. Esch 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.
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 ISO 1873-1 was prepared by Technical Committee
lSO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials.
This fourth edition cancels and replaces the third edition
(ISO 1873-1:1991) and includes the following changes:
The designatory property “isotactic index” has been replaced by the
designatory properties “tensile modulus of elasticity” and “impact
strength ”.
ISO 1873 consists of the following Parts, under the general title
Plas tics - Polypropylene (PP) moulding and extrusion materials:
- Part 7: Designation System and basis for specifications
- Part 2: Preparation of test specimens and determination of proper-
ties

Part 1:
Designation System and basis for specifications
1 Scope
1.1 This part of ISO 1873 establishes a System of designation for polypropylene (PP) thermoplastic material,
which may be used as the basis for specifications.
1.2 The types of polypropylene plastics are differentiated from each other by a classification System based on
appropriate levels of the designatory properties
a) tensile modulus of elasticity
b) impact strength
c) melt mass-flow rate (MFR)
and on information about basic polymer Parameters, intended application and/or method of processing, important
properties, additives, colorants, fillers and reinforcing materials.
1.3 This part of ISO 1873 is applicable to all propylene homopolymers and to copolymers of propylene with a
content of other l-olefins of less than 50 % (m/m), as well as blends of polymers containing at least 50 % (dm)
of aforementioned polymers.
lt 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.
This part of ISO 1873 does not apply to propylene-based rubber.
0 ISO
ISO 1873=1:1995(E)
1.4 lt is not intended to imply that materials having the same designation give necessarily the same perform-
ante. This part of ISO 1873 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).

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 coding, the individual-item
block is subdivided into 5 data blocks comprising the following information:
- Data block 1: Identification of the plastic by its Symbol PP in accordance with ISO 1043-1 and information
about the polymerization process or composition of the polymer (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).
For the purpose of specifications, a fifth data block may be added containing additional in-

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
3.1 Data block 1
In this data block, after the hyphen, polypropylene plastics are identified by the Symbol “PP ”, in accordance with
ISO 1043-1, followed by a hyphen and a Single code-letter giving additional information on the polymer as specified
in table 1.
