Primary Benchmarks

Lab Results vs. BIS Standards

Comparison between MTL-GICEA tested parameters and Bureau of Indian Standards (BIS) statutory benchmarks referenced in the report.

IS 1077 / IS 3495 Pt-1Compressive Strength13.6 N/mm²Peak unit: 14.7 N/mm²BIS minimum: 10 N/mm²

Quality-test summary: Across the six specimens logged in this report, all units met the IS 1077 Class 12.5 load-bearing threshold, stayed within the IS 1077 water-absorption limit, and showed no efflorescence.

Classification note: Bricks between 12.5 N/mm² and 14.9 N/mm² qualify for Class 12.5 heavy load-bearing specification per IS 1077. Typical Indian clay bricks average Class 3.5–7.5.
