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 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 28941-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic
materials.
ISO 28941 consists of the following parts, under the general title Plastics — Poly(phenylene ether) (PPE)
moulding and extrusion materials:
⎯ Part 1: Designation system and basis for specifications
ISO 28941-1 is a revision of ISO 15103-1, the revision concerning principally the inclusion of melt volume-flow
rate as a designatory property and the inclusion of additional ranges of values of the other designatory
properties. In order to give users time to switch from ISO 15103-1 to ISO 28941-1, ISO 15103-1 will remain in
force for a number of years after publication of ISO 28941-1. During this period, ISO 15103-2 will effectively
be Part 2 of this International Standard.

INTERNATIONAL STANDARD ISO 28941-1:2008(E)

Plastics — Poly(phenylene ether) (PPE) moulding and extrusion
materials —
Part 1:
Designation system and basis for specifications
1 Scope
1.1 This part of ISO 28941 establishes a system of designation for PPE thermoplastic materials, which may
be used as the basis for specifications.
1.2 The types of PPE plastic are differentiated from each other by a classification system based on
appropriate levels of the designatory properties
a) temperature of deflection under load
b) melt volume-flow rate
c) Charpy notched impact strength
d) flammability
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 28941 is applicable to all PPE materials, including those modified with polystyrene or
polyamide or other materials.
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 necessarily have the same
performance. This part of ISO 28941 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 ISO 15103-2, 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 3.1).

2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

3 Designation system
3.1 General
The designation system for thermoplastics is based on the following standardized pattern:
Designation
Identity block
Description block Individual-item block
International
(optional)
Standard
Data block Data block Data block Data block Data block
number block
1 2 3 4 5
The designation consists of an optional description block, reading “Thermoplastics”, and an identity block
comprising the International Standard number and an individual-item block. For unambiguous coding, the
individual-item block is subdivided into five data blocks comprising the following information:
— Data block 1: Identification of the plastic by its symbol PPE in accordance with ISO 1043-1 and
information about the composition of the polymer (see 3.2).
— Data block 2: Position 1: intended application or method of processing (see 3.3).
Positions 2 to 8: important properties, additives and supplementary information (see 3.3).
— Data block 3: Designatory properties (see 3.4).
— Data block 4: Fillers or reinforcing materials and their nominal content (see 3.5).
— Data block 5: For th
