15、-rior use other than cellular products, piping, tubing, andwindow and door profiles used in finished building products.The information contained in this standard is intended to behelpful to producers, distributors, and users, and to promoteunderstanding between buyers and sellers. It is also intende
16、d toserve as the basis for requirements on finished interior buildingproducts which are either made from or employ rigid PVCprofile extrusions in their construction.5. Classification5.1 This standard covers three classes of rigid PVC interior-profile extrusions as follows:Class 1Normal impactClass 2
17、Intermediate impactClass 3High impact6. Materials and Manufacture6.1 This specification covers profile extrusions made fromplastics conforming to the requirements of SpecificationD1784. Class 1 extrusions shall meet the requirements speci-fied in Specification D1784 for Class 12454 compound. Class2
18、extrusions shall meet the requirements for Class 14323compound. Class 3 extrusions shall meet the requirements forClass 1-40031-54-0000 compound. Refer to Table 1 in Speci-fication D1784.6.2 Use of rigid PVC recycled plastic, as defined in GuideD7209 is permitted in this product if all the requireme
19、nts in thesections on Materials and Manufacture (Section 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 10-5cmcmC (5.5 10-5 in.in.F).NOTE 3Non-PVC materials may be
20、used as a capstock.6.4 Rework MaterialClean, homogeneous PVC reworkmaterial or rework material containing PVC capstock gener-ated from the manufacturers own production of the same classcompound is permitted for use by the same manufacturerprovided that the extruded profiles meet all the requirements
21、 ofthis specification. Clean principally PVC rework materialcontaining non-PVC capstock is permitted for use only in thesubstrate of a capstocked product by the same manufacturer,providing that the extruded profiles meet all of the require-ments of this specification.6.5 The PVC compound in extruded
22、 section shall maintainuniform color and be free of any visual surface 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 betwee
23、n the supplier and purchaser.7.2 Dimensional StabilityThe dimensional 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.)
24、 thickness or less shallhave a 3.0 % maximum shrinkage.7.3 Extrusion 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 a
25、s adequately fused and of satisfactory quality. Theextrusion qualities 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 th
26、e requirements of this specification. Each producer ordistributor 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 docu
27、mentwith a high degree of assurance his claim that all of therequirements 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-profil
28、eextrusions to determine their compliance with the requirementsof 6.5.8.3 Conditioning of SpecimensCondition the test speci-mens in accordance with ProcedureAof Practice D618, exceptthat the minimum conditioning time shall be 24 h.8.4 Test ConditionsConduct the tests the Standard Labo-ratoryAtmosphe
29、re of 23 6 1C (73.4 6 1.8F) and 50 6 10 %relative humidity, unless otherwise specified in the applicabletest method.8.5 Dimensional StabilityDetermine the dimensional sta-bility in accordance with Test Method D1042, except that thetest cycle shall consist of heating the specimens for 30 min ina unif

I
31、n the test procedure described, the interior-profileextrusions will 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 Expans

Product Marking9.1 To aid identification of products conforming to allrequirements of this specification, producers and distributorsshall include a statement of compliance in conjunction withD3678 142their name and address on product labels,
33、 invoices, salesliterature, and the like. The following statement is suggestedwhen sufficient space is available:“The product conforms to all of the requirements establishedin ASTM D3678, developed cooperatively with the industryand published by ASTM.”“Full responsibility for the conformance of this
34、 product tothis specification is assumed by (name and address of produceror distributor).”9.2 The following abbreviated statement is suggested whenavailable space on labels is insufficient for the full statement:“Conforms to ASTM D3678 (name and address of produceror distributors).”9.3 All packing,
35、packaging, and marking provisions ofPractice D3892 shall apply to this specification.10. Packaging10.1 The interior-profile extrusions shall be packaged insuch a manner as to provide reasonable protection againstdamage in ordinary handling and transportation.11.
