Scope
This International Standard specifies
a) a method for determining the resistance of glass
to attack by a boiling aqueous Solution of sodium
carbonate and sodium hydroxide. The resistance
is measured inversely by the loss in mass per
unit surface area of the glass;
b) a classification of glass according to the alkali
resistance determined by the method of this
International Standard.
NOTE 1 The method of test according to this International
Standard is also applicable
