Useful carpet thickness

Test method to determine the thickness of the pile above the substrate of a textile floor covering.

Resistance to damage at cut edges

Test method to determine the susceptibility of textile floor coverings to mechanical damage at cut edges. It is applicable to all textile floor coverings both as sheet materials and as tiles.

Number of tufts and/or loops

Test method to determine the number of tufts and/or loops per unit Iength and per unit area of a carpet.

Lisson Tretrad test

The Lisson Tretrad testing machine is used to determine 4 aspects of textile floor coverings.

Dimensional stability of resilient floorcoverings

Test method to determine the dimensional stability and curling of resilient floor coverings, in the form of sheets, tile or planks after exposure to heat.

Dimensional stability of carpet tiles

The resistance to dimensional variation due to the effects of water and heat conditions is an essential requirement of carpet tiles.

Radient panel test

Test method to measure and describe of the response of materials, products, or assemblies to heat and flame under controlled conditions

Useful mass (volume)

Test method to determine the total mass per unit area, total pile mass per unit area, and mass of pile per unit area above the substrate, and for the calculation of measured surface pile density and measured pile fibre volume ratio, of textile floor coverings.

Carpet wear - changes in appearance

Testing and evaluation of changes in appearance by means of Vetterman drum and hexapod tumbler tester

Castor chair test

Evaluation of the change of appearance and stability of a textile floor covering or any damage caused by detachment of layers, opening of joints, or crazing of a resilient or laminate floor covering under the movement of a castor chair.
