Determining the effect of exposure of safety glazing material to temperature and humidity conditions by boiling
Specimens are immersed in hot water and then boiling water for a
specified period of time and inspected for bubbles or other defects.
Two water baths each of sufficient size to hold the test specimen fully immersed vertically on edge, for the duration of test.
Three specimens of size 300 mm × 300 mm manufactured in a manner
identical with the impact test specimens (see Appendix B) and of like thickness shall be tested. These specimens may be cut from production samples of the size and thickness submitted for impact testing. For heat strengthened or toughened laminated glass, test specimens may be cut from a similar original sheet of annealed laminated glass.
a) Immerse the specimens vertically on edge in a bath of water maintained at a temperature of 66 ±3°C for 3 min.
(b) Quickly transfer the specimens to a bath of water maintained at boiling point. Immerse the specimens vertically on edge in the bath for 2 h.
(c) Remove the specimens and examine for bubbles or other defects.
