钢化玻璃标准（Tempered glass standard）
Inspection standard for tempered glass
1. performance requirements
1.1 with low iron tempered glass suede (also known as Bai Boli),
in the wavelength range of the solar cell spectral response
(320-1100nm) in the light transmission rate of more than 91%,
the reflectivity is higher for the more than 1200 nm infrared
light. This glass can also resist the radiation of solar
ultraviolet ray, and the light transmittance does not decrease.
(NM is nanometer)
1.2 glass passed or met national standards GB/T 9963-1998 and
GB 2828-87.
2. quality requirements and inspection methods
2.1 thickness
The thickness is 3.2mm, and the allowable deviation is 0.2mm.
2.2 size
The allowable deviation of the length of 2.2.1 rectangular flat
glass shall be in accordance with the provisions of table 1.
Table 1 the allowable side deviation of rectangular tempered
glass is mm
Allowable deviation of thickness side (L)
L = 10001000, L > 20002000 < L < 3000 > 3000 L

The diagonal allowable deviation of 2.2.2 rectangular flat
glass shall be in accordance with the provisions of table 2.
Table 2 the allowable value of diagonal difference of
rectangular tempered glass is mm
Allowable value of thickness diagonal difference
The length is less than or equal to 20002000 < L < 3000 > 3000
