17、ance and Use4.1 The purpose of this specification is to establish on a national basis, a recognized standard of quality for rigid poly(vinylchloride) (PVC) interior-profile extrusions for interior use other than cellular products, piping, tubing, and window and doorprofiles used in finished building
18、 products. The information contained in this standard is intended to be helpful to producers,distributors, and users, and to promote understanding between buyers and sellers. It is also intended to serve as the basis forrequirements on finished interior building products which are either made from o
19、r employ rigid PVC profile extrusions in theirconstruction.5. Classification5.1 This standard covers three classes of rigid PVC interior-profile extrusions as follows:Class 1Normal impactClass 2Intermediate impactClass 3High impact6. Materials and Manufacture6.1 This specification covers profile ext
20、rusions made from plastics conforming to the requirements of Specification D1784.Class 1 extrusions shall meet the requirements specified in Specification D1784 for Class 12454 compound. Class 2 extrusionsshall meet the requirements for Class 14323 compound. Class 3 extrusions shall meet the require
21、ments for Class 1-40031-54-0000compound. Refer to Table 1 in Specification D1784.6.2 Rigid Use of rigid PVC recycled plastic, as defined in Guide D7209, may be used is permitted in this product if all therequirements in the sections on Materials and Manufacture (Section 6), and on Physical Requireme
22、nts (Section 7) are met by theextrusions containing PVC recycled plastic.6.3 All Class compounds shall have a minimum coefficient of linear expansion of 10 10-5 cmcm cm/cm/C C (5.5 10-5in./in./F). in.in.F).NOTE 3Non-PVC materials may be used as a capstock.6.4 Rework MaterialClean, homogeneous PVC re
23、work material or rework material containing PVC capstock generated fromthe manufacturers own production of the same class compound may be used is permitted for use by the same manufacturerprovidingprovided that the extruded profiles meet all the requirements of this specification. Clean principally

25、rm color and be free of any visual surface or structural changes,such as peeling, chipping, cracking, flaking, or pitting.7. Physical Requirements7.1 DimensionsThe size, thickness, and dimensional tolerances of the interior-profile extrusions shall be as agreed uponbetween the supplier and purchaser
26、.7.2 Dimensional StabilityThe dimensional stability of the interior-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 of 2.2 %; thoseof 1.02-mm (0.040-in.) thickness or less shall h
27、ave a 3.0 % maximum shrinkage.7.3 Extrusion QualityThe extrusion quality of Class 1 extrusions shall be determined by immersion in anhydrous acetone inaccordance with the requirements of 8.6. Specimens of extrusions having not more than 25 % surface attack shall be consideredas adequately fused and
28、of satisfactory quality. The extrusion qualities of Class 2 and Class 3 extrusions shall be as agreed uponbetween the supplier and purchaser.8. Test Methods8.1 GeneralUse the inspection and test procedures contained in this section to determine the conformance of products to therequirements of this
29、specification. Each producer or distributor who represents his products as conforming to this specification mayutilize statistically based sampling plans that are appropriate for each particular manufacturing process, but shall keep suchD3678 142essential records as are necessary to document with a
30、high degree of assurance his claim that all of the requirements of thisspecification have been met. Additional sampling and testing of the product, as may be agreed upon between supplier andpurchaser, is not precluded by this section.8.2 Visual InspectionVisually examine the interior-profile extrusi

32、6 1C (73.4 6 1.8F) and 50 6 5 %10 %relative humidity, unless otherwise specified in the applicable test method.8.5 Dimensional StabilityDetermine the dimensional stability in accordance with Test Method D1042, except that the testcycle shall consist of heating the specimens for 30 min in a uniformly
33、 heated oven at a temperature of 82.0 6 0.6C (180 6 1F).6 1F).8.6 Extrusion QualityDetermine the extrusion quality in accordance with Test Method D2152, except that the test specimensshall be 25.40 to 50.80 mm (1 to 2 in.) in length and sufficient in number to ensure testing the complete cross secti
34、on. In the testprocedure described, the interior-profile extrusions will normally swell and soften in contact with anhydrous acetone. In some casesthere may be surface attack. Disintegration is defined as complete separation of flakes or pieces from the body of the extrusion.8.7 Coeffcient of Linear
