FDIS 1288-4
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
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 part of ISO 1288 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 1288-4 was prepared by Technical Committee ISO/TC 160, Glass in building,
Subcommittee SC 2, Use considerations in conjunction with Technical Committee CEN/TC 129, Glass in building.
ISO 1288 consists of the following parts, under the general title Glass in building — Determination of the bending
strength of glass:
 Part 1: Fundamentals of testing glass
 Part 2: Coaxial double ring test on flat specimens with large test surface areas
 Part 3: Test with specimen supported at two points (four point bending)
 Part 4: Testing of channel shaped glass
 Part 5: Coaxial double ring test on flat specimens with small test surface areas
This Standard has been based on EN 1288-4 Glass in building - Determination of the bending strength of glass" -
Part 4 : Testing of channel shaped glass prepared by Technical Committee CEN/TC 129 "Glass in building"/WG8
"Mechanical Strength".
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,
Switzerland and the United Kingdom.

Glass in building — Determination of the bending strength of
glass — Part 4: Testing of channel shaped glass
1 Scope
This International Standard specifies a method for determining the bending strength (defined as the profile bending
strength) of wired or unwired channel shaped glass for use in buildings.
The limitations of this part of this International Standard are described in ISO 1288-1.
