This standard specifies the requirements for medium density coirboards made from coir fibres and synthetic resins. It covers the material composition, dimensions, tolerances, and essential physical and mechanical properties like density, strength, and water resistance for boards used in general purposes like furniture, partitions, and panelling. The standard also details the testing methods, sampling procedures, and marking criteria for conformity.

Practical Notes
These boards are not intended for primary structural or load-bearing applications.
Verify the binder type (e.g., PF for boiling water resistance vs. UF for interior use) based on the intended application's moisture exposure.
Always check for the ISI mark and manufacturer's batch number on the board as per marking requirements in Clause 7 to ensure product quality and traceability.
