Specification for mineral gypsum — IS 1290 (1973) Testing

The latest applicable standard is IS 1290:2023, Mineral Gypsum — Specification (Third Revision). BIS published the revised standard on 10 July 2023, and it superseded IS 1290:1973 from 10 August 2023.

IS 1290:2023 establishes requirements for mineral gypsum and provides methods for its sampling and testing. It is relevant to mineral gypsum used in areas such as building materials, plaster production and cement manufacturing.

Testing includes parameters such as free water, silica and other insoluble matter, iron and aluminium as oxides, magnesium oxide, calcium sulphate and chlorides. These tests help assess the chemical quality and conformity of mineral gypsum.

Testing helps verify that mineral gypsum meets the specified quality requirements before it is used in relevant industrial applications. It can support quality control, supplier evaluation and conformity assessment.

Yes. Current laboratory listings include testing facilities for IS 1290:2023 and its specified chemical parameters, demonstrating that the revised standard is actively used for mineral gypsum testing.

Yes. The 2023 third revision replaced the earlier IS 1290:1973 (Second Revision). Therefore, businesses referring to the standard today should consider the requirements of IS 1290:2023 rather than treating the 1973 edition as current.
