2、ase of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers requirements for polyvi-nylidene drainage systems for corrosiv
3、e applications. Require-ments for material, pipe and fittings are included. Polyvi-nylidene fluoride includes emulsion/suspension polymerizationand copolymers of vinylidene fluoride/hexafluoropropyleneproduced by either method.1.2 These requirements apply to Schedule 40 and 80 IPSand SDR 21 pipe siz
4、es. Pipe and fittings are to be joined byheat fusion or mechanical methods using the equipmentsupplied by the manufacturers.1.3 This specification is not intended to provide for inter-changeability between plastic pipe and fittings from differentmanufacturers, but it does allow for transition fittin
5、gs forjoining one manufacturers product to anothers product, pro-vided the joining technique used is other than heat fusion.1.4 This specification is not for polyvinylidene pressuresystems.1.5 The values stated in inch-pound units are to be regardedas the standard. The values in parentheses are for
6、informationonly.1.6 Notes and appendixes are not a mandatory part of thisspecification.1.7 The following safety hazard caveat pertains only to thetest method portion, Section 8, of this specification: Thisstandard does not purport to address all of the safety concerns,if any, associated with its use
