Application:

Technical parameters:

Instruction:

Adjust the measurement and set up to track the maximum data. Adjust the span of the support block according to request.
Adjust the position of measuring head, to ensure that the measuring head is beyond 2mm-3mm of the plane of three support feet.
Gently stick the surface of the glass to ensure that three supporting feet are able to touch the glass.
Slide the measure location and read the data.

Data：

Scope:

Determining the effect of exposure of safety glazing materials to temperature and humidity condition by boiling

Principle:

Specimens are immerse in hot water and boiling water for specified period of time and inspect bubbles and others defects

Apparatus:

The apparatus include two water baths, each of sufficient size to hold the test specimen fully immersed vertically on edge for the duration test.

Samples:

Three specimen of size 300mm*300mm manufacture in a manner identical with impact test specimens 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 specimen may be cut from a similar original sheet of annealed laminated glass

Procedure:

Immerse the specimens vertically on edge in a bath of water maintained at a temperature of 66°C±3°C for 3 min
Quickly transfer the specimens to a bath of water maintain at boiling point. Immerse the specimens vertically on edge for 2 h
Remove the specimens and examine for the bubbles and others defects
