Classification5.1 This standard covers three classes of rigid PVC interior-profile extrusions as follows:Class 1Normal impactClass 2Intermediate impactClass 3High impact6. Materials a
17、nd Manufacture6.1 This specification covers profile extrusions made fromplastics conforming to the requirements of SpecificationD 1784. Class 1 extrusions shall meet the requirements speci-fied in Specification D 1784 for Class 12454 compound. Class2 extrusions shall meet the requirements for Class
18、14323compound. Class 3 extrusions shall meet the requirements forClass 1-40031-54-0000 compound. Refer to Table 1 in Speci-fication D 1784.6.2 Rigid PVC recycled plastic, as defined in Guide D 5033,may be used in this product if all the requirements in thesections on Materials and Manufacture (Secti
19、on 6), and onPhysical Requirements (Section 7) are met by the extrusionscontaining PVC recycled plastic.6.3 All Class compounds shall have a minimum coefficientof linear expansion of 10 3 10-5cm/cm/C (5.5 3 10-5in./in./F).NOTE 3Non-PVC materials may be used as a capstock.6.4 Rework MaterialClean, ho
20、mogeneous PVC reworkmaterial or rework material containing PVC capstock gener-ated from the manufacturers own production of the same classcompound may be used by the same manufacturer providingthat the extruded profiles meet all the requirements of thisspecification. Clean principally PVC rework mat
21、erial contain-ing non-PVC capstock may be used only in the substrate of acapstocked product by the same manufacturer, providing thatthe extruded profiles meet all of the requirements of thisspecification.6.5 The PVC compound in extruded section shall maintainuniform color and be free of any visual s
22、urface or structuralchanges, such as peeling, chipping, cracking, flaking, orpitting.7. Physical Requirements7.1 DimensionsThe size, thickness, and dimensional tol-erances of the interior-profile extrusions shall be as agreedupon between the supplier and purchaser.7.2 Dimensional StabilityThe dimens
23、ional stability of theinterior-profile extrusions shall be determined in the extrusiondirection in accordance with 8.5. Extrusions over 1.02 mm(0.040 in.) in thickness shall have a maximum shrinkage of2.2 %; those of 1.02-mm (0.040-in.) thickness or less shallhave a 3.0 % maximum shrinkage.7.3 Extru
24、sion QualityThe extrusion quality of Class 1extrusions shall be determined by immersion in anhydrousacetone in accordance with the requirements of 8.6. Specimensof extrusions having not more than 25 % surface attack shall beconsidered as adequately fused and of satisfactory quality. Theextrusion qua
25、lities of Class 2 and Class 3 extrusions shall be asagreed upon between the supplier and purchaser.8. Test Methods8.1 GeneralUse the inspection and test procedures con-tained in this section to determine the conformance of productsto the requirements of this specification. Each producer ordistributo
26、r who represents his products as conforming to thisspecification may utilize statistically based sampling plans thatare appropriate for each particular manufacturing process, butshall keep such essential records as are necessary to documentwith a high degree of assurance his claim that all of thereq
27、uirements of this specification have been met. Additionalsampling and testing of the product, as may be agreed uponbetween supplier and purchaser, is not precluded by thissection.8.2 Visual InspectionVisually examine the interior-profileextrusions to determine their compliance with the requirementso

30、xtrusion QualityDetermine the extrusion quality inaccordance with Test Method D 2152, except that the testspecimens shall be 25.40 to 50.80 mm (1 to 2 in.) in length andsufficient in number to ensure testing the complete crosssection. In the test procedure described, the interior-profileextrusions w
31、ill normally swell and soften in contact withanhydrous acetone. In some cases there may be surface attack.Disintegration is defined as complete separation of flakes orpieces from the body of the extrusion.8.7 Coeffcient of Linear ExpansionConduct this test inaccordance with Test Method D 696.9.

The following s
33、tatement issuggested when sufficient space is available:“The product conforms to all of the requirements establishedin ASTM D 3678, developed cooperatively with the industryand published by ASTM.”“Full responsibility for the conformance of this product tothis specification is assumed by (name and ad
34、dress of produceror distributor).”9.2 The following abbreviated statement is suggested whenavailable space on labels is insufficient for the full statement:D 36782“Conforms to ASTM D 3678 (name and address of produceror distributors).”9.3 All packing, packaging, and marking provisions ofPractice D 3
