This International Standard specifies the characteristics of non-cushioned, heterogeneous floor coverings, based on poly(vinyl chloride) (PVC), supplied in either tile or roll form. Products may contain a transparent, non-PVC factory finish. To encourage the consumer to make an informed choice, this International Standard includes a classification system (see ISO 10874) based on the intensity of use, which shows where these floor coverings give satisfactory service. It also specifies requirements for marking.
