scope:

This Standard specifies a method for determining the bending strength, including the effects of the edges, of flat soda lime glass mainly for use in building. This Standard applies to flat glass with a nominal thickness¹⁾ of 3 mm to 19 mm, and does not apply to perforated glass or glass consisting of two or more panes (laminated glass and double glazing glass).

Note ¹⁾ A nominal designation of glass thickness, which is a value of thickness in millimetres expressed either to a whole number or to one decimal place.

NOTE The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 1288-3 : 2016 Glass in building - Determination of the bending strength of glass - Part 3 : Test with specimen supported at two points (four point bending) (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
