This standard specifies requirements for flexible PVC floor-covering in the form of tiles having a smooth or embossed wearing surface. It does not apply to tiles consisting of layers of plastics and fibrous materials, backed or sandwiched, or tiles consisting of a base material laminated with a wear layer which may be plain, patterned, embossed or printed.NOTES:1. Tiles having an embossed surface or other design effects penetrating any part of their thickness, may be supplied as agreed between the purchaser and supplier. The permanence of such surfaces will be dependent on the traffic density and this should be a consideration in the choice of these materials.2. Appendix A sets out a summary of the limits applying to flexible PVC tiles tested for compliance with this standard.3. Advisory information on the determination of compliance of a 'lot' with this standard is given in Appendix B.
