2 terms and definitions

The following terms and definitions apply to this document.

2.1 Impurity

An inclusions (such as grains, bubbles, nodules, and stones) that cause changes in the original transmitted light inside the glass.

[MIL-STD-1241A. 1987 Chapter 3; ISO 10110-3..1996, definition 2.2]

3 test principle

A uniform diffuse infrared light was used to irradiate the sample, and the impurity image in the sample was collected by the infrared imaging system to observe the image on the computer screen

Impurities formed by gray spots and highlights. Infrared optical sulfur glass impurity test principle shown in Figure 1.
