IS 14587:1998 is the Indian Standard (BIS) for prelaminated medium density fibre board -specification. This standard specifies the manufacturing, performance, and testing requirements for prelaminated Medium Density Fibreboard (MDF) intended for general purposes like furniture and interior applications. It defines material grades based on density, dimensional tolerances, and performance criteria for the laminated surface, such as resistance to abrasion, stains, and cracking.
