Annex A (informative) Bibliography

Defines the determination of the bending strength of monolithic glass for use in buildings. Insulating units or laminated glass testing is excluded from this standard. This standard describes: explanations of the reasons for designing different test methods; limitations to the test methods; consideration to be taken into account when testing glass, and gives pointers to safety requirement for the personnel operating the test equipment. Test methods in this standard are intended to provide large numbers of bending strength values that can be used as the basis for statistical evaluation of glass strength. Test methods are specified in detail in EN 1288-2, EN 1288-3, EN 1288-4, AND EN 1288-5.
