BS ISO 11856:2014 pdf free.Textile floor coverings一Test methods for the determination of fibre bind using a Modified Martindale Machine
The method in this International Standard uses a modified Martindale fabric abrasion machine to assess fibre loss in pile carpets by weighing the amount of fibre removed at specified intervals. It is applicable to all types of cut pile, wool-rich textile floor coverings.

Mount the specimen onto the baseplate and clamp into place, ensuring the specimen remains substantially flat. Clean the polyurethane rubbing heads using diethyl ether, allow to dry, and attach to the mounting plate.
Set the counter for 500 rubs. When the machine has stopped, remove all loose fibre from the specimen using tweezers (do not handle fibre with fingers), place in the container, and weigh to the nearest 0,001 g.
Continue the test removing and recording masses of all loose fibre at the following intervals: 1 000 rubs,5 000 rubs, 10 000 rubs, 15 000 rubs, 20 000 rubs, 25 000 rubs, and 30 000 rubs.
Calculate the total mass of loose fibre in mg for each specimen at each interval. Furthermore,calculate the mean of result at each stage.
Plot a graph of the total mass loss of loose fibre for each specimen against the number of rubs.
Calculate the mass of loose fibre in mg per rub for each specimen between 10 000 rubs and 30 000 rubs. Calculate the mean result.BS ISO 11856 pdf download.
