Gypsum Plaster Boards Specification Part 1 Plain Gypsum Plaster Boards — IS 2095: Part 1 (2023) Testing

The latest edition is IS 2095 (Part 1):2023, titled Gypsum Plaster Boards – Part 1: Plain Gypsum Plaster Boards. It is the revised edition of IS 2095 (Part 1):2011 and provides updated requirements for quality and performance evaluation.

IS 2095 (Part 1):2023 helps establish consistent quality and performance requirements for plain gypsum plaster boards. Compliance testing evaluates important properties such as strength, dimensional characteristics, density, water absorption and other specified requirements.

The standard applies to plain gypsum plaster boards intended for use in building construction and related applications. The boards are evaluated against the specified requirements for materials, dimensions, physical performance, appearance and other characteristics defined by the standard.

Testing may include dimensional tolerances, density, flexural breaking load, impact resistance, surface hardness, loading capability, water absorption, fire-related performance and finish. Chemical testing may also cover specified composition-related parameters.

Chemical evaluation can include calcium sulphate dihydrate (CaSO₄·2H₂O), free water, pH, silica (SiO₂) and chloride content. These parameters assist in assessing the composition and conformity of gypsum plaster boards.

IS 2095 (Part 1):2023 is the revised edition of the earlier 2011 standard. The revision updates and consolidates requirements and testing provisions for plain gypsum plaster boards, making it important for manufacturers to assess products against the applicable current requirements.

Testing helps manufacturers verify whether their plain gypsum plaster boards meet specified BIS requirements for composition, dimensions and performance. It can support product quality control, conformity assessment and documentation for applicable BIS certification requirements.

Yes. Water absorption is among the specified performance characteristics considered for plain gypsum plaster boards under the standard. Testing helps determine the board's behaviour when exposed to water under the prescribed test conditions.
