Structural Granite — IS 3316 (1974) Testing

IS 3316:1974 provides defined requirements for structural granite, enabling manufacturers, suppliers and construction stakeholders to evaluate important characteristics such as compressive strength, specific gravity and water absorption before material is used.

Laboratories may request product details, sample information, applicable specification, quantity and the required test parameters before accepting a sample. The exact documentation and sample quantity can vary according to the laboratory and testing scope.

Yes. Certko can assist businesses in understanding applicable IS 3316:1974 test requirements and in identifying suitable laboratories for structural granite testing based on the required parameters and project requirements.

Structural granite testing can be conducted through laboratories having the appropriate testing facilities and scope. Current National Test House listings specifically show compressive strength, specific gravity and water absorption testing under IS 3316:1974. Certko can help businesses identify suitable testing requirements and laboratory options.

The strength and physical-property tests referenced by IS 3316:1974 use related Indian Standards, including IS 1121 (Part 1) for compressive strength, IS 1122 for true specific gravity and IS 1124 for water absorption.

Yes. Current BIS publications continue to list IS 3316:1974 as the specification for structural granite, while current National Test House records list testing for compressive strength, specific gravity and water absorption against the standard.

Structural granite should be free from flaws, injurious veins, cavities and similar imperfections that could adversely affect structural integrity, strength or appearance. The standard also addresses certain deleterious minerals that may affect appearance and polishing.

Yes. The standard includes requirements concerning the section and dimensions of structural granite, including slab shape and dimensional tolerances. It also specifies quality requirements relating to surface condition and structural integrity.

Water absorption testing indicates how much moisture a granite sample can absorb under the specified test conditions. Lower absorption is generally important for durability, and IS 3316:1974 specifies a maximum water absorption of 0.50%.
