BS ISO 10834:1992

This standard BS ISO 10834:1992 Textile floor coverings. Non-destructive measurement of pile thickness above the backing. WRONZ gauge method is classified in these ICS categories:

• 97.150 Floor coverings

This International Standard specifies a method for the measurement of the thickness of pile above the backing of a textile floor covering and is applicable to all textile floor coverings having a pile of cut or looped yarn. Where areas of different construction or thickness exist, these should be tested separately if possible. This method is non-destructive of the floor covering specimen and is useful particularly for production control in manufacture and for measurements on installed carpets.

Due to different loading factors, this method and that of ISO 1766, in which the pile fibres are cut from the substrate, may not give identical results. In case of dispute or where maximum accuracy is required, the pile thickness shall be determined by the method of ISO 1766.

Because of this, care shall be exercised in comparing textile floor coverings with different substrates when using this gauge.

Specifies a method which is useful for production control in manufacture and for measurements on installed carpets.
