Designation:D406817An American National StandardStandard Specification forChlorinated Polyethylene(CPE)Sheeting for ConcealedWater-Containment Membrane1This standard is issued under the fixed designation D4068;the number immediately following the designation indicates the year oforiginal adoption 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 flexible chlorinated polyethyl-ene(CPE)sheeting which is used without mastic,bedding,orcoating for construction of concealed water-containment mem-branes in applications where there is potential for costlysecondary damage from leakage,and where very long-termreliable performance is essential.Examples are fountains,pools,planters,shower and safe pans,tile tubs,and similarinstallations where the membrane is inaccessible once con-structioniscomplete.Includedarerequirementsforcomposition,strength and toughness,test methods,workman-ship criteria,and methods of marking.1.2 Manufacturers have the option to use recycled materialsin this product.Recycled materials must be in accordance withthe requirements in Section 4.1.3 The test methods used to characterize the sheeting areintended to ensure quality and performance and are notnecessarily adequate for design purposes.Test methods havebeen selected to be conducted primarily with liquids thatsimulate the environments to which the membrane will besubjected during actual installation and use.1.4 This specification does not cover water-containmentmembranes exposed in use to ultraviolet light or direct sun-light.1.5 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.NOTE1There is no known ISO equivalent to this standard.1.6 The following safety hazards caveat pertains only to thetest method portion,Section 14,of this specification:Thisstandard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.Referenced Documents2.1 ASTM Standards:2D412 Test Methods for Vulcanized Rubber and Thermoplas-tic ElastomersTensionD543 Practices for Evaluating the Resistance of Plastics toChemical
