What is the minimum required density for bamboo mat board?

The density shall not be less than 600 kg/m³ (Clause 8.1).

What are the standard thicknesses available?

Standard thicknesses range from 3 mm to 25 mm as specified in Clause 6.1.

Is bamboo mat board suitable for outdoor use?

Yes, provided it is manufactured with Boiling Water Proof (BWP) grade phenolic resin as per Clause 4.2.1 and IS 848.

What is the permissible tolerance on thickness for a 12mm board?

For boards over 8 mm thick, the tolerance is ± 5 percent, which is ± 0.6 mm for a 12 mm board (Table 2).

This standard specifies the requirements for bamboo mat board, a panel product made by hot-pressing resin-coated woven bamboo mats. It covers materials, manufacturing, dimensions, physical and mechanical properties, and testing methods for boards intended for general purposes like furniture, panelling, and partitions.

Quick Reference Values

Minimum Density600 kg/m³

Moisture Content Range5 to 15 %

Maximum Water Absorption (24h immersion)20 % by mass

Minimum Modulus of Rupture (Parallel to face mat)40 N/mm²

Minimum Modulus of Elasticity (Parallel to face mat)4000 N/mm²

Minimum Screw Withdrawal Strength (Face)1000 N

Practical Notes

The properties of the board are anisotropic; strength is significantly higher parallel to the grain of the outer mats compared to perpendicular.

Specify phenolic resin (BWR/BWP type) for applications requiring resistance to moisture or exterior use. Urea-formaldehyde (MR type) is suitable for dry interior use only.

Proper on-site storage is crucial; stack flat on a level surface with bearers and protect from direct rain and sun to prevent warping and moisture damage.
