3、Defense.1. Scope1.1 This specification describes the required properties andtest methods for a cold liquid-applied elastomeric-type mem-brane, one- or two-component, for waterproofing buildingdecks and walls subject to hydrostatic pressure in buildingareas to be occupied by personnel, vehicles, or e
4、quipment. Thisspecification applies only to a membrane system that will becovered with a separate wearing course, traffic course, orbackfill.NOTE 1See Guide C898 and Guide C1471 for proper application ofmembrane.1.2 There are no ISO standards similar or equivalent to thisASTM standard.1.3 The values
5、 stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1
6、.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Referenced Do
