Abstract: Abstract: With fire control institutions reform deepening, fire supervisory duty shift, and the application of glass component products, how to control quality of single?panel?fireproofing?glass is becoming more and more important. Aiming at the shortcomings of the existing testing standard in this paper, a single?panel?fireproofing?glass?rapid detection technology was porposed. By measuring the light transmittance, glass surface stress refractive index of single?panel?fireproofing?glass， the type and quality of single?panel?fireproofing?glass can be quickly distinguished.

Key words: Key words:?single panel fireproof glass, refractive index, surface stress
