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, 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, 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.

The committee responsible for this document is ISO/TC 160, Glass in building, Subcommittee SC 1, Product considerations.

ISO 11485 consists of the following parts, under the general title Glass in building — Curved glass:

• Part 1: Terminology and definitions
• Part 2: Quality requirements
• Part 3: Requirements for curved tempered and curved laminated safety glass

Introduction

Curved tempered safety glass has a breakage behaviour that is different to annealed glass. This behaviour is a direct result of the high surface prestress and the stress profile within the glass.

Curved tempered safety glass has a known behaviour under accident human impact.

Curved laminated safety glass has safety properties that are different to annealed glass. This behaviour is a direct result of the assembly of two or more glass panes with one or more interlayers.

Curved laminated safety glass has a known behaviour under accidental human impact.

1 Scope

This part of ISO 11485 defines the conditions to classify a curved glass product as a curved safety glass.

This part of ISO 11485 classifies curved tempered glass and curved laminated glass as safety glasses used in buildings, by performance under impact and by mode of breakage. The classification by drop height corresponds to graded values of energy transmitted by the impact of a person.

The classification system in this part of ISO 11485 relates to increasing personal safety by

• the reduction of cutting and piercing injuries to persons, and
• the containment characteristics of the material.

This part of ISO 11485 covers fracture characteristics, including fragmentation test and the physical and mechanical characteristics of curved tempered safety glass for use in buildings.
