11、4. PE Pipe and PP Layer Requirements4.1 PE Pipe Requirements:4.1.1 The PE pipe shall meet all the requirements ofSpecification D2513, excluding marking, when tested in accor-dance with 6.1. Marking shall be in accordance with Section 7.4.2 PP Layer Requirements:4.2.1 The PP peelable layer shall be m

19、 Pipe Requirements5.1 Squeeze-OffThe peelable pipe manufacturer shallqualify squeeze-off of peelable pipe per Specification D2513using squeeze tools meeting Specification F1563. The samegap stops appropriate for the standard PE pipe DR shall beused, and the same squeeze-off procedures for PE pipe pe
20、r therequirements in Specification D2513 shall be followed.5.2 Outdoor StorageThe peelable PP layer shall protectthe PE pipe from UV radiation to provide outdoor storage ofpeelable pipe for up to five years from date of manufacture.The peelable pipe shall be capped on both ends.5.3 ReworkThere shall
21、 be no rework used in the manu-facture of peelable pipe.6. Test Methods6.1 PE Pipe TestingTo determine conformance to Speci-fication D2513, the PE pipe shall be tested exclusive of theco-extruded PP peelable layer.6.2 PA Peel Forcethe peel force test shall be in accor-dance with ISO 17454.6.3 Impact
22、 testthe impact test shall be in accordance withEN 1411.7. Marking7.1 Marking shall be applied to the co-extruded peelablelayer and shall conform to the marking requirements ofSpecification D2513, except that peelable pipe made accordingthis standard specification shall be marked ASTM F2830.7.2 The
23、PE pipe is not marked.7.3 The marking shall include the words “Peelable Pipe” toindicate this is peelable pipe.8. Joining8.1 For all joining methods (butt fusion, saddle fusion,socket fusion, electrofusion and mechanical fittings), the PPpeelable layer shall be removed immediately before joiningusin
24、g only a cutting tool prescribed by the pipe manufacturer.This cutting tool is designed to safely remove the peelablelayer without damaging the PE pipe. After removing thepeelable layer, the PE pipe is joined immediately using ASTMD2513 PE pipe standard joining procedures as recommendedby the respec
25、tive manufacturer.NOTE 2After removing the peelable layer, the PE pipe should not becontaminated prior to joining.8.2 The PP layer shall be peeled back sufficiently so thatthere is no interference with the recommended joining proce-dure.8.3 Electrofusion joints do not require scraping since thePE la
26、yer is clean after removal of the PP peelable layer. Toassure electrofusion joint integrity using peeled PE pipe thathas not been scraped, the PE pipe and peelable PP layer shallnot have release agents, lubricants, or other additives that willexude to the surface, and negatively affect the integrity
27、 of theelectrofusion joints. An electrofusion joint made on non-scraped peeled pipe and evaluated per Specification F1055 toensure a good quality joint without scraping shall demonstratethis.9.
