Modulus of rupture:

Modulus of rupture is the maximum load carrying capacity of a wood sample. It is generally used in tests of bending strength to quantify the stress required to cause breakage. It is reported in units of psi (per square inch).

Test Method: IS: 1734 (P-11)1983, RA-2003, IS: 1708 (P-5) 1985

Modulus of elasticity:

This test helps in determining the flexural stiffness and modulus of elasticity properties of wood-based materials by nondestructive testing using transverse vibration in the vertical direction.

Test Method: IS: 1734 (P-11)1983, RA-2003, IS: 1708 (P-5)1985

Internal bond strength:

The purpose of this test is to design a compression shear device for easy and fast measurement of the bond shear strength of wood-based materials.

Test Method: IS: 1734 (P-4) 1983, RA-2003

Moisture Content Test:

This test helps in determining the moisture content (MC) of solid wood, veneer, and other wood-based materials, including those that contain adhesives and chemical additives.

Test Method: IS: 1734 (P-1) 1983, RA-2003

Density Test:

Analyzing tree density can serve great ecological and scientific function. These tools are easy to understand and eliminate the risk of damage done to tree specimens.

Test Method: 1708 (P-2)1986, RA-2008

Bending Strength Test:

In bending, it is assumed that wood is linearly elastic for low values of stress, i.e., the stress and strain are proportional to each other and the output on stress-strain curve is either an elastic or straight-line plot.

Test Method: IS: 1734 (P-11) 1983

Compression Strength Test:

The Box Compression Test (BCT) measures the compressive strength of boxes made of corrugated fibreboard as well as wooden boxes and crates. It provides a plot of deformation versus compressive force . Containers other than boxes can also be subjected to compression testing such as drum, bucket, etc.

Wood-based Panels Test:

This test helps in determining the structural panels of uniform properties within a panel. It is useful for evaluating plywood of clear, straight-grained veneers, and determining the effect of chemical or preservative treatments, construction, principal direction with respect to direction of stress, and other variables that are expected to uniformly influence the panel.

Test Method:IS: 4020 (P-1 to 16)1998

Absorbability Test:

This test helps in determining the quantity of water absorbed in a specified time through the surface of an overlaid wood-based panel. The test method measures the rate of water weight gain within a controlled surface area of the overlaid panel surface when exposed to standing water.

Test Method: ASTM D 5795.

Thickness Swelling Test:

This test helps in understanding the impact of humidity, temperature and ambient environment on the hygroscopic thickness swelling rate of wood fibre and wood fibreboard. To measure the swelling rate, a model stating the thickness of composites exposed to water vapour conditions has been developed.

Test Method: IS: 2380 (P-17)1977, RA-203

Screw Holding Ability Test:

The ability to hold screws in both face and edges is an important attribute of wood.

Test Method: IS: 2380 (P-14)1977, RA-2003, IS: 1708 (P-15)1986

Dimensions Stability Test:

Dimensional stability is measured by noting the length, width and thickness of the test pieces after conditioning to constant mass at 35% RH, 25°C and after conditioning at 85% RH and 25°C. The dimensional stability is expressed as the sum of the percentage changes in each dimension between these limits.

Test Method: IS: 4020 (P-3)1998

Wood Quality Test:

This test helps in determining the quality of wood. The kind of wood that is used has a lot of bearing on the lifespan of any furniture. It may be made of hardwood, softwood, or engineered wood.

Test Method: IS: 4020 (P-4)1998

Impact of a Soft Body:

To ensure that cladding panels are not at undue risk of failure from typical impacts they should be tested for both hard and soft body impact resistance which is acceptable by British Standards.

Test Method: IS: 4020 (P-8)1998

Indentation Resistance Test:

Indentation hardness tests are used to determine the hardness of a material to deformation.

Test Method: IS: 4020 (P-5)1998

Flush Door Shutter Test:

Flush Door Shutters means forming a continuous surface. It ‘flushes’ or ‘blends’ with the wall and embellishes a look of longevity to the wall. Flush doors are the most economical choice of builders because of their durability, dimensional accuracy, as well as freedom from warps & delamination when subjected to atmospheric changes.

Test Method: IS: 2202

Pre Laminated Particle Board Test:

This test helps in determining the resistance to Steam, Dimensions, Water absorption, Resistance to Cracking, Density variation, Swelling in water, Adhesion of plies, Moisture, Swelling due to surface absorption, Resistance to stains, Resistance to water, Cigarette burn,  Tensile strength, Screw withdrawal strength, Modulus of rupture, and Abrasion resistance.

Test Method: IS: 12823

MDF / MDP Board:

MDF does not contain knots or rings, making it more uniform than natural woods during cutting and in service. Medium-density fibreboard is an engineered wood product formed by breaking down hard or softwood residuals and mixing it with a resin binder and wax and exposing the resultant formation to high temperature and pressure. MDF is denser than plywood.

Test Method: IS: 12406 & IS: 3087

FRP / GRP Door Shutter Test:

This test helps in determining the features like quality, design, weather resistance and durability.

Test Method: IS: 4020 / 14856

Ply-wood Test:

The plywood test helps in determining the usefulness and durability of plywood and quantity of moisture in the wood.

Test Method: IS: 303 / 1989
