This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 88.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

European Foreword
This document (prEN 13496:2021) has been prepared by Technical Committee CEN/TC 88 “Thermal
insulating materials and products”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13496:2013.
The main changes with respect to the previous edition are listed below:
— addition of triaxial meshes;
— addition of 28-day conditioning in alkali solution;
— amended accuracy of expression of results.

1 Scope
This document specifies equipment and procedures for determining the tensile strength and elongation
of rectangular and triaxial glass fibre meshes which are used for the reinforcement of the base coat in
External Thermal Insulation Composite Systems (ETICS).
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.
EN 1607:2013, Thermal insulating products for building applications - Determination of tensile strength
perpendicular to faces
EN ISO 9229:2007, Thermal insulation — Vocabulary (ISO 9229:2007)
ISO 1887:2014, Textile glass — Determination of combustible-matter content
3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 9229:2007 and the following
apply.
3.1
tensile strength of glass fibre mesh
strength of the test specimen at failure relative to the width of the test specimen
3.2
elongation of glass fibre mesh
elongation of the test specimen 9512999 relative to the initial length
4 Principle
The maximum tensile strength and corresponding elongation of glass fibre meshes is determined using a
tensile testing machine. The tensile strength of the meshes shall be tested in both test directions, the warp
and the weft direction. For triaxial meshes, two weft directions are recognized and both shall be tested.
Three types of conditioning can be carried out before the test:
– A, no conditioning, testing as-delivered
– B, rapid, 24 h warm alkali conditioning
– C, standard, 28 day alkali conditioning
5 Apparatus
5.1 Tensile testing machine, appropriate for the range of force and displacement involved, capable of
having a constant crosshead speed adjusted to (100 ± 5) mm/min.
It shall be capable of measuring the force with an accuracy of at least 10 N in accordance with
EN 1607:2013.
