19、extruded LayerAny material used as a coextrudedlayer on the inside or outside surface of the PE conduit shalladhere to the surface of the PE and shall not delaminate innormal use. It shall not degrade or lower the performance ofthe PE conduit.4.3 Aerial ApplicationsPE material for black conduit inlo
20、ng-term above ground applications, such as aerial suspen-sion, shall be stabilized with a minimum of 2 % by weightcarbon black having an average particle size less than or equalto 20 nanometers.4.4 Outdoor Storage Stability:4.4.1 Black ConduitPE material for black conduit innon-UV exposed applicatio
21、ns shall be stabilized with a mini-mum of 2 % by weight carbon black in accordance withSpecification D 3350.NOTE 1Acceptable cell for Color and UV resistance properties inTable 1 may be achieved by utilizing a precompounded material or byblending a base natural material with a color concentrate.4.4.
22、2 Colored ConduitPE material for colored conduit innon-UV exposed applications shall be suitably protectedagainst UV degradation so that conduit may be stored outsideand uncovered for a period of not less than one year. Permanentcolor identification shall be permitted to be as solid color, asstripes
23、, as a co-extruded skin, or a combination of these. Ifstripes are specified, multiple stripes shall be required, to aid inthe identification of the conduit. Colored conduit shall maintainits color for a period of 1 year when stored outside, or asotherwise agreed to by the specifier and producer.4.4.
24、2.1 Solid yellow or black with yellow stripes shall notbe used for identification of conduit due to risk of misidenti-fication with gas pipe.5.
