ISO DIS 11856 is a draft international standard for the determination of the fibre bond of Spinning & weaving floor coverings, which is tested using a modified Martindale machine. The standard specifies a method for evaluating the fibre bond strength of Spinning & weaving floor coverings such as carpets using a modified Martindale machine. By simulating the abrasion in actual use, the mass loss or Appearance change of the fibres after a specific number of rubs is measured. It is suitable for all types of cut pile carpets and Spinning & weaving floor coverings with high wool content, providing an important basis for product quality control and performance evaluation.
