Pulverized fuel ash - Lime bricks — IS 12894 (2002) Testing

IS 12894:2002 is the BIS standard for Pulverized Fuel Ash-Lime Bricks – Specification. It specifies requirements for the materials, dimensions, quality and performance of pulverized fuel ash-lime bricks used in building construction.

Important tests include dimensions, tolerances, general requirements, wet compressive strength, drying shrinkage, efflorescence and water absorption. BIS laboratory listings currently show these parameters for testing under IS 12894:2002.

The standard evaluates key performance characteristics such as dimensional accuracy, wet compressive strength, drying shrinkage, water absorption and efflorescence to assess the quality and suitability of the bricks.

Testing helps manufacturers verify that pulverized fuel ash-lime bricks meet the specified BIS requirements for quality and performance. It can also support product consistency, quality control and certification-related requirements.

BIS laboratory listings currently show testing for Group I, II and III and class designations including 3.5, 5, 7.5, 10, 12.5, 15, 17.5, 20, 25 and 30.

Yes. BIS laboratory testing scopes for IS 12894:2002 include Clause 9 – Marking, along with requirements covering materials, dimensions, tolerances and other specified characteristics.

IS 12894:2002 remains a relevant BIS standard for pulverized fuel ash-lime bricks. BIS records show that the standard was reaffirmed in January 2022 and has two amendments. Users should refer to the latest applicable BIS documents when testing or assessing conformity.
