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

DRAFT INTERNATIONAL STANDARD ISO/DIS 1172:2022(E)
Textile-glass-reinforced plastics — Prepregs, moulding
compounds and laminates — Determination of the textile-
glass and mineral-filler content — Calcination methods

WARNING — This International Standard does not give details of the precautions that should be

taken to meet health and safety requirements. The test methods described require the use of

high temperatures and concentrated acids. It is the responsibility of the user of this International

Standard to follow the appropriate health and safety procedures.
1 Scope

This International Standard specifies two calcination methods for the determination of the textile glass

and mineral filler content of glass-reinforced plastics:

Method A: for the determination of the textile glass content when no mineral fillers are present.

Method B: for the determination of the textile-glass and mineral-filler content when both

components are present.
This International Standard is applicable to the following types of material:
— Prepregs made from yarns, rovings, tapes or fabrics;
— SMC, BMC and DMC moulding compounds;
— textile-glass-reinforced thermoplastic moulding materials and granules;

— filled or unfilled textile-glass laminates made with thermosetting or thermoplastic resins.

The methods are not applicable to the following types of reinforced plastic:
— those containing reinforcements other than textile glass;

— those containing materials which do not completely burn off at the test temperature (for example,

those based on silicone resin);

— those containing mineral fillers which degrade at temperatures below the minimum calcination

temperature.

For these materials, ISO 11667, Fibre-reinforced plastics - Moulding compounds and prepregs

-Determination of resin, reinforcement-fibre and mineral-filler content - Dissolution method, may be used.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 472 and ISO 8604 apply.

4 Principle

A test specimen is weighed and subsequently calcinated at a defined temperature. The specimen is

then reweighed and the non combustible matter content (glass + filler) obtained by determining the

difference in mass of a test specimen before and after calcination in one of the following ways:

a) In the case of materials containing no fillers the glass content is calculated directly from the

difference in mass (method A);

b) In the case of materials containing both glass and filler, the glass and filler remaining after

calcination are separated by dissolution of the filler in hydrochloric acid. The difference between

the mass of the specimen before calcination and the mass of the dried specimen after reaction

with acid is used to measure the glass content. The filler content is obtained by calculating the

difference between the mass of the specimen after calcination and the mass of the dried spec
