MediumCurrent
Natural stone products — Slabs for cladding — Requirements
Specifies requirements for granite slabs used specifically for external and internal cladding, a subset of IS 3316's scope.
EN 12058:2015CEN (European Committee for Standardization), Europe
MediumCurrent
Natural stone products — Slabs for floors and stairs — Requirements
Defines characteristics for granite slabs for flooring and stairs, a common structural use but more specific than IS 3316.
EN 1467:2012CEN (European Committee for Standardization), Europe
LowCurrent
Natural stone — Rough blocks — Requirements
Focuses on the quality requirements for the raw granite block from the quarry, prior to processing into finished products.
Key Differences
≠IS 3316 specifies minimum values for Tensile Strength (7 N/mm²) and Shear Strength (15 N/mm²), which are not typically required properties in ASTM C615 or EN product standards.
≠IS 3316 requires a minimum Hardness of 6 on the Mohr's scale. Modern international standards prefer performance-based tests like Abrasion Resistance (e.g., ASTM C1353 or EN 14157) instead of the qualitative Mohr's scale.
≠The European (EN) standards are highly fragmented by application (cladding, paving, flooring), whereas IS 3316 is a single, comprehensive standard for all 'structural granite' uses.
≠IS 3316 specifies 'Transverse Strength', while ASTM C615 specifies 'Modulus of Rupture' and EN standards specify 'Flexural Strength'. While conceptually similar, the test methods and calculations (e.g., ASTM C99 vs. EN 12372) differ, leading to different minimum required values.
≠IS 3316 classifies granite into Fine, Medium, and Coarse-grained categories. ASTM C615 does not have an internal classification system, relying on the supplier's geological description.
Key Similarities
≈All standards (IS, ASTM, EN) consider compressive strength, flexural/transverse strength, and water absorption as core performance indicators for structural stone quality.
≈Both IS 3316 and its international counterparts require that the granite be generally sound, uniform in texture, and free from cracks, seams, or other defects that would impair structural integrity or appearance.
≈Compliance in all standards is verified through laboratory testing of representative samples taken from the source material, ensuring objective quality control.
≈The fundamental purpose across all these standards is to provide a specification that ensures the selected granite is suitable and durable for use in building construction.
