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.

For an explanation on the meaning of ISO specific terms and expressions related to conformity

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

to Trade (TBT) see the following URL: Foreword - Supplementary information

The committee responsible for this document is ISO/TC 61, Plastics, Subcommittee SC 13, Composites

and reinforcement fibres.

INTERNATIONAL STANDARD ISO 1887:2014(E)
Textile glass — Determination of combustible-matter
content
1 Scope

This International Standard specifies a method for the determination of the combustible-matter content

of products made from textile glass, such as continuous-filament yarns, staple-fibre yarns, rovings,

chopped strands, milled fibres, fabrics, chopped-strand and continuous-filament mats, and other glass

reinforcements.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
combustible-matter content

ratio of the mass of material removed on calcination from a dried textile glass product to the mass of the

dried product

Note 1 to entry: This ratio is expressed as a percentage in this International Standard. It is equal to the content

of size or finish on the textile glass product when the size or finish is completely combustible without significant

residue (i.e. primarily organic products).
3 Principle

Test specimens, dried under prescribed conditions, are weighed before and after calcination at

a temperature of 625 °C ± 20 °C or, with types of glass which are unstable at this temperature, at a

temperature between 500 °C and 600 °C, also kept constant to within 20 °C.
4 Apparatus

4.1 Air-circulation oven, for drying specimens, capable of being maintained at 105 °C ± 5 °C or the

chosen drying temperature and maintained to within ±5 °C (see 6.3).

4.2 Muffle furnace, capable of being maintained, with a tolerance of ±20 °C, at any desired temperature

up to 625 °C, the temperature being measured at the centre of the muffle furnace with the door closed.

4.3 Desiccator, containing a suitable desiccant, for example silica gel, calcium chloride, phosphorous(V)

oxide.

4.4 Specimen holder, made from a material stable at the test temperature, allowing the best possible

air circulation around the test specimen and designed to prevent loss of material. The holder may be a

porcelain crucible, a basket made of stainless-steel gauze, etc.
4.5 Stainless-steel tongs, for handling test specimens and holders.
4.6 Balance, accurate to 0,1 mg.
4.7 Polished-metal templates, for the preparation of test specimens.

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 1887 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 13, Composites and

reinforce ment fibres.
