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 of the voluntary nature of standards, the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISO's adherence to the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www.iso.org/iso/foreword.html .

This document was prepared by Technical Committee ISO/TC 160, Glass in building, Subcommittee SC 1, Product considerations.

Introduction

Heat strengthened soda lime silicate glass has a higher resistance to thermal stress and an enhanced mechanical strength when compared to annealed soda lime silicate glass.

1 Scope

This document specifies product definitions, product characteristics (i.e. tolerances, flatness, edgework), fracture characteristics, including fragmentation, and the physical and mechanical characteristics of flat heat strengthened soda lime silicate glass for use in buildings.

This document does not cover surface finished glasses (e.g. sandblasted, acid etched) after heat strengthening.

This document does not cover curved (bent) glass.

Other requirements, not specified in this document, can apply to heat strengthened soda lime silicate glass which is incorporated into assemblies (e.g. laminated glass or insulating glass units), or undergoes an additional treatment (e.g. coating). The additional requirements are specified in the appropriate glass product standard. Heat strengthened soda lime silicate glass, in this case, does not lose its mechanical or thermal characteristics.
