Introduction
1. Background and significance of the standard
GB/T 37798-2019 "Evaluation of anti-slip performance of ceramic tiles" is an important national standard proposed by the China Building Materials Federation, which aims to unify the evaluation method and grading standard of anti-slip performance of ceramic tiles. This standard is based on actual use needs and technology evolution analysis, combining laboratory testing and on-site evaluation, and provides a scientific technical basis for the building sanitary ceramics industry.
2. Anti-slip performance classification standard
| Anti-slip grade code | Static friction coefficient (dry state) f | Pendulum slip resistance value (wet state) β | Critical angle α/(°) | Anti-slip ability |
|---|---|---|---|---|
| Ad | f≥0.70 | β>54 | α≥24 | High |
| P5 | - | β>54 | - | High |
| C | - | - | α≥24 | High |
3. Recommendations for Standard Implementation
Case Study: A construction project uses Ad grade ceramic tiles with a static friction coefficient of 0.85. Both laboratory tests and on-site evaluations meet high anti-slip requirements. The implementation of this standard ensures the safety of public areas and reduces the risk of slipping.
Test method optimization suggestions:
- Laboratory condition control: maintain temperature (23±2)°C and relative humidity (50±10)%
- Test specimen preparation: clean and dry to avoid contamination affecting the test results
- Instrument calibration: regularly check the accuracy of the pendulum slip resistance value meter
