This code of practice provides guidelines for the selection and use of medium-density particle boards (MDPB) in various applications. It covers criteria for choosing the right grade of board based on end-use, environmental conditions, and required performance. The standard also includes recommendations for proper storage, handling, installation, and finishing.

Practical Notes
Particle boards swell irreversibly when exposed to water or high humidity. Always use moisture-resistant (MR) grade boards (Grade I) in kitchens or bathrooms and ensure all edges are properly sealed with paint or sealant.
Use appropriate particle board screws for better grip; standard wood screws can strip the material easily. Self-tapping screws with a coarse thread are often recommended.
Always pre-drill pilot holes for screws, especially near edges, to prevent the material from bulging or splitting.
