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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
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.
Attention is drawn to the possibility that some of the elements of this part of ISO 2580 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 2580-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee
SC 9, Thermoplastic materials.
This fourth edition cancels and replaces the third edition (ISO 2580-1:1997), which has been technically revised.
ISO 2580 consists of the following parts, under the general title Plastics — Acrylonitrile/butadiene/styrene (ABS)
moulding and extrusion materials:
— Part 1: Designation system and basis for specifications
— Part 2: Preparation of test specimens and determination of properties

INTERNATIONAL STANDARD ISO 2580-1:2000(E)
Plastics — Acrylonitrile/butadiene/styrene (ABS) moulding and
extrusion materials —
Part 1:
Designation system and basis for specifications
1 Scope
1.1 This part of ISO 2580 establishes a system of designation for acrylonitrile/butadiene/styrene (ABS) thermo-
plastic materials, which may be used as the basis for specifications.
1.2 The types of ABS plastic are differentiated from each other by a classification system based on appropriate
levels of the designatory properties
a) Vicat softening temperature
b) melt volume-flow rate
c) Izod impact strength
d) flexural modulus
and on information about composition, intended application and/or method of processing, important properties,
additives, colorants, fillers and reinforcing materials.
1.3 This part of ISO 2580 is applicable to all acrylonitrile/butadiene/styrene materials (in which the styrene
component may be styrene itself and/or an alkyl-substituted styrene), consisting of a continuous phase based
mainly on copolymers of styrene (and/or an alkyl-substituted styrene) and acrylonitrile, a dispersed elastomeric
phase based mainly on polybutadiene, and other components in such quantities as specified in data block 1.
It applies to ABS materials ready for normal use in the form of powder, granules, pellets or chips, unmodified or
modified by colorants, additives, fillers, etc.
This part of ISO 2580 does not apply to materials
2
� with an Izod impact strength of less than 3 kJ/m ;
� containing less than 40 % by mass of butadiene in the elastomer of the elastomeric phase;
� containing less than 10 %
