Thisperformance requirement will also apply to containers that arefurther processed (such as ceramic enamel decorations), fol-lowing the original manufacture, by reheating the containerabove the strain point and cooling to room temperature.

8、TheScratch Test (Section 5) can be used as an alternative to TestMethods C148. Containers tested in accordance with theScratch Test shall show no fractures.4.1.2 Non-transparent GlassIf glass condition (color,decoration, etc.) prohibits sufficient light transmission for useof Test Methods C148, anne

Test Methods5.1 ScopeThis Scratch Test Method is designed to ensure

12、that residual stress is reduced to a commercially acceptablelevel in annealed soda-lime-silicate glass containers that areintended for use as candle containers. It provides an alternativemethod to Test Methods C148. Two methods of performing theScratch Test are covered:5.1.1 Test Method AScratch Tes

A new piece of emerypaper/cloth is to be used for every piece tested.5.4.3 After using either method A or B, fill each article withwater at the same room temperature as the glass. Wait fifteenminutes, then empty the water and exami
