Introduction

1. Standard Overview

GB/T 43892—2024 Test Method for Spectral Transmittance of Quartz Glass is the latest national standard issued by the People's Republic of China, which is used to regulate the spectral transmittance test of quartz glass in different wavelength ranges. This standard was proposed by the China Building Materials Federation and is managed by the National Technical Committee for Standardization of Industrial Glass and Special Glass.

2. Background of Standard Formulation

With the increasing demand for high-performance quartz glass in the fields of optics, optoelectronics, etc., it is essential to accurately measure its spectral transmittance characteristics. This standard is based on the principle of spectrophotometer and combined with industry practical experience, aiming to provide unified technical specifications for related product testing.

3. Comparison of standard frameworks

Chapter	GB/T 43892—2024	Comparison description
Scope	Applicable to the spectral transmittance test of quartz glass, other materials can be used for reference.	Added detailed provisions for curved surface specimens.
Terms and definitions	GB/T13962 and JC/T 2205 are referenced to ensure terminology consistency.	Added mathematical expressions for spectral transmittance.
Instruments and Equipment	Specify the technical indicators and test conditions of the spectrophotometer in detail.	Added requirements and usage suggestions for the integrating sphere.

4. Implementation Suggestions

4.1 Preparation before testing

Ensure that the spectrophotometer is warmed up for at least 10 minutes to obtain stable measurement results. For curved samples, it is recommended to use a sample holder and adjust the incident spot size to the recommended range to reduce refraction and reflection errors.

4.2 Data Processing and Reporting

When processing data, it is recommended to record the transmittance value at the specified wavelength and calculate the arithmetic mean of the transmittance within the wavelength range. The test report should include detailed information about the sample, test conditions and results.
