Title: TEST REPORT

Report No.: 25202000537

Sample Information:
– Sample Name: Rock Tiles
– Original Place: China
– Sample Sender: Quanzhou Huali Ceramics Co., Ltd.
– Sample Date: 12/03/2020 – 17/03/2020

Testing Authority:
– State Key Testing Laboratory of Building Ceramics and Sanitary Ware
– Comprehensive Technology Centre of Foshan Customs

Test Standards:
– Testing was conducted according to GB/T 4100-2015 (Appendix G) for dry-pressed ceramic tiles, Grade BIa, with water absorption (E) ≤ 0.5%.

Test Results:
1. Dimensions and Surface Quality:
– Length: Deviation within +0.6% and -0.03% to +0.01%
– Width: Deviation within +0.6% and +0.12% to +0.18%
– Thickness: Deviation within +5.96% and -0.5% to +0.2%
– Straightness of Sides: Maximum deviation from straightness within +0.9% to -0.5%

2. Rectangularity:
– Maximum deviation from rectangularity within -0.08% to +0.04%

3. Surface Flatness:
– Maximum deviation from flatness within -0.04% to -0.01%

4. Water Absorption:
– Percentage of water absorption: ≤ 3% (Class 3)

5. Breaking Strength:
– Average breaking strength: ≥ 1300 N
– Minimum breaking strength: ≥ 35 N/mm²

6. Abrasion Resistance:
– Passed the test for resistance to surface abrasion of glazed tiles intended for use on floors

7. Chemical Resistance:
– Resistance to low concentrations of acids and alkalis: Passed the tests
– Resistance to high concentrations of acids and alkalis: Passed the tests

8. Staining Resistance:
– Resistance to staining: Class 5

9. Crazing Resistance:
– Resistance to crazing: Passed the test for glazed tiles

Conclusion:
The tested sample of rock tiles met the requirements specified in GB/T 4100-2015 (Appendix G). It exhibited satisfactory results in terms of dimensions, surface quality, water absorption, breaking strength, abrasion resistance, chemical resistance, staining resistance, and crazing resistance.
