ISO/CEN PARALLEL ENQUIRY
The CEN Secretary-General has advised the ISO Secretary-General that this ISO/DIS covers a
subject of interest to European standardization. In accordance with the ISO-lead mode of
collaboration as defined in the Vienna Agreement, consultation on this ISO/DIS has the same
effect for CEN members as would a CEN enquiry on a draft European Standard. Should this draft
be accepted, a final draft, established on the basis of comments received, will be submitted to a
parallel two-month FDIS vote in ISO and formal vote in CEN.

In accordance with the provisions of Council Resolution 15/1993 this document is circulated
in the English language only.
Conformément aux dispositions de la Résolution du Conseil 15/1993, ce document est
distribué en version anglaise seulement.

To expedite distribution, this document is circulated as received from the committee
secretariat. ISO Central Secretariat work of editing and text composition will be undertaken at
publication stage.
Pour accélérer la distribution, le présent document est distribué tel qu'il est parvenu du
secrétariat du comité. Le travail de rédaction et de composition de texte sera effectué au
Secrétariat central de l'ISO au stade de publication.

THIS DOCUMENT IS A DRAFT CIRCULATED FOR COMMENT AND APPROVAL. IT IS THEREFORE SUBJECT TO CHANGE AND MAY NOT BE REFERRED TO
AS AN INTERNATIONAL STANDARD UNTIL PUBLISHED AS SUCH.
IN ADDITION TO THEIR EVALUATION AS BEING ACCEPTABLE FOR INDUSTRIAL, TECHNOLOGICAL, COMMERCIAL AND USER PURPOSES, DRAFT
INTERNATIONAL STANDARDS MAY ON OCCASION HAVE TO BE CONSIDERED IN THE LIGHT OF THEIR POTENTIAL TO BECOME STANDARDS TO WHICH
REFERENCE MAY BE MADE IN NATIONAL REGULATIONS.
RECIPIENTS OF THIS DRAFT ARE INVITED TO SUBMIT, WITH THEIR COMMENTS, NOTIFICATION OF ANY RELEVANT PATENT RIGHTS OF WHICH THEY
ARE AWARE AND TO PROVIDE SUPPORTING DOCUMENTATION.

prEN/ISO 1288-5
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 EN 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 EN ISO 1288-5 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.
EN 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 1288-5 Glass in building - Determination of the bending strength of glass" -
Part 5 : Coaxial double ring test on flat specimens with small test surface areas 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.
