2、tion or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers poly(vinyl chloride) (PVC)flexible sheeting w
3、hich is used without mastic, bedding, orcoating for construction of concealed water-containment-membranes in applications where there is potential for costlysecondary damage from water leakage and very long-termreliable performance is essential. Examples are fountains,pools, planters, shower and saf
4、e pans, tile tubs, or similar wetinstallations where the membrane is inaccessible once theconstruction is complete. Included are requirements for mate-rials and sheeting, test methods, workmanship criteria, andmethods of marking.1.2 Recycled materials may be used in this product inaccordance with th
5、e requirements in Section 5.1.3 The tests are intended to ensure quality and performanceand are not intended for design purposes. Tests have beenselected to be conducted primarily with liquids that simulatethe environment to which the membrane will be subjectedduring actual use.1.4 This specificatio
6、n does not cover water-containmentmembranes exposed to ultraviolet light.1.5 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.1.6 There is no known ISO equivalent to this standard.1.7 The following precautionary caveat p
7、ertains only to thetest method portion, Section 13, of this specification: Thisstandard does not purport to address all of the safety concerns,if any, associated with its use.
