ISO 4918:2009
Resilient, textile and laminate floor coverings — Castor chair test
ISO 4918:2008 specifies methods for assessment of the wear behaviour of textile floor coverings, assessment of the change in colour (glossing) of needled floor coverings without a pile, assessment of the general structural integrity of textile floor coverings, and determination of susceptibility to surface crazing, construction integrity and joint stability for resilient or laminate floor covering, including joints.
The methods involve subjecting the test piece to the movement of a castor chair.
