Introduction
Interpretation of the National Standard of the People's Republic of China GB/T 36142—2018
| Standard Dimensions | Technical Requirements | International Comparison |
|---|---|---|
| Measurement Principle | Spectral photometry, CIE LAB uniform color space calculation. | Consistent with ISO standards, using D65 lighting conditions. |
| Measurement Range | Transmitted and reflected color and color difference, suitable for single-layer or multi-layer architectural glass. | Compatible with internationally accepted glass testing standards. |
| Instrument requirements | Spectrophotometer, integrating sphere and other high-precision optical measurement equipment. | Comply with ISO/IEC 17025 measurement standards. |
Explanation of professional terms
Transmission color: The color characteristics of light after passing through glass under the condition that the incident angle of light is not greater than $10^{\circ}$.
Reflection color: The color performance of light after reflection from glass, which is divided into vertical reflection and deflection reflection.
In actual applications, spectrophotometer is the core instrument for measuring the color and color difference of architectural glass, and its accuracy directly affects the test results.
Implementation Recommendations
Equipment Selection: It is recommended to use a high-precision spectrophotometer with an integrating sphere system to ensure that the measurement accuracy meets the standard requirements.
Staff Training: Operators must undergo professional training to master the terms and measurement methods defined in the standard, especially the color difference calculation part.
Data Management: It is recommended to establish a digital management system to record test parameters, results and analysis reports for traceability and quality control.
