In order to get information on revising JIS (Japanese Industrial Standards) for Toughened Glass of Ships' Side Scuttles, several series of breaking test were carried out on toughened glass produced by domestic manufacturers.As the present standards give no reference to mat toughened glass, attention was paid to the property of the kind. Different test methods-hydrostatic pressure test, explosive pressure test, impact test by dropping steel ball and the punch test recommended by ISO-were studied.Some results are as follows:1)it is not so difficult to revise the JIS concerned according to the ISO recommendation;2)the method of testing recommended by ISO is practically acceptable;3)emery-grouned mat toughened glass is remarkably tender under shock load, while corroded one shows rather improved performance.Original data reproduced for further examination.
