1. SCOPE 1.1 This standard applies to flexible, polyvinyl chloride (PVC) membranes
for use in roofing and waterproofing. 1.2 This standard also provides a basis for evaluating PVC membranes used
on decking subject to pedestrian traffic, although additional criteria
such as skid resistance, abrasion resistance and resistance to puncture
from sustained loads may be important. These additional criteria have
not been sufficiently studied by the committee for inclusion in the
standard. 1.3 For more detailed information on intended uses, see par. 8.2. 1.4 The testing and evaluation of a product against this standard may
require the use of materials and/or equipment that could be hazardous.
This document does not purport to address all the safety aspects
associated with its use. Anyone using this standard has the
responsibility to consult the appropriate authorities and to establish
appropriate health and safety practices in conjunction with any
existing applicable regulatory requirements prior to its use.
