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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

This document was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for
the transport of fluids, Subcommittee SC 6, Reinforced plastics pipes and fittings for all applications.
This second edition cancels and replaces the first edition (ISO 7510:1997), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— modified the title;
— clarified accuracy statements;
— eliminated specific sample size;
— referenced ISO 3126 for dimension determination;
— allowed use of test specimens taken from mechanical property test samples.

INTERNATIONAL STANDARD ISO 7510:2017(E)
Plastics piping systems — Glass-reinforced plastics
(GRP) components — Determination of the amounts of
constituents
1 Scope
This document specifies a method for the determination of constituent materials of a test sample
cut from a glass-reinforced plastics (GRP) component intended for use in a piping system. It includes
determination of resin, glass, aggregate and filler contents.
It is also applicable to the determination of the type and arrangement of the reinforcements. If used
to determine the amounts of constituent materials in layered constructions it may be necessary to
separate the laminate layers by cutting or splitting and testing each separately.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements 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.

4 Principle
A test piece of known size and mass is ignited to burn off the resin, and the residue analysed by
separating and weighing the constituents [loss on ignition (LOI) is a common term for such testing].
If the construction includes organic reinforcements, such as surfacing veils, or processing aids, such
as thermoplastic mesh or filaments, these will be burned off with the resin. Typically such materials if
used are in small amounts and will not introduce significant error in the determination of raw material
contents. Also, organic materials used in glass fibre reinforcement sizing or binder will be burned off.
The amounts of such materials are very small.
NOTE 1 In the case of filled laminates, especially those containing fillers of small particle size (including
thixotropic agents), accurate analysis of the constituents can prove difficult. This is because of the difficulty in
separating such fillers from the other constituents and the risk of some filler being lost during combustion.
This test method can be used to determine and monitor the fibre architecture of the laminate layers
used in the piping component.
NOTE 2 It is assumed that the following te
