This standard specifies the methods for conducting physical and mechanical tests on small, clear specimens of split bamboo. It covers procedures for determining properties like moisture content, specific gravity, static bending strength, compressive strength, and tensile strength, adapting methods used for timber testing.
Methods of tests for split bamboo
Quick Reference Values
Static bending specimen dimensionst x 1.5t x (16t + 50) mm
Compression parallel to grain specimen dimensionst x 1.5t x 4t mm
Loading rate for static bending test2.5 mm/min
Loading rate for compression parallel to grain test0.6 mm/min
Oven temperature for moisture content103 ± 2 °C
Key Formulas
Modulus of Rupture (MOR) = (3 * P_max * L) / (2 * b * d^2)
Modulus of Elasticity (MOE) = (P * L^3) / (4 * y * b * d^3)
Maximum Crushing Stress = P_max / A
Practical Notes
This standard is heavily based on IS 1708 for timber; the primary difference is the specimen preparation and dimensions which are adapted for split bamboo.
The thickness 't' of the split bamboo (i.e., the culm wall thickness) is the fundamental dimension upon which all test specimen sizes are based.
Ensuring specimens are 'clear' (free of defects like nodes, cracks, or insect damage) is crucial for obtaining accurate material property data.
