23、ell vinyl products are given in Table 2.7. Workmanship, Finish, and Appearance7.1 Closed cell vinyl furnished under this specification shall be manufactured from poly(vinyl chloride) or copolymers thereof,together with the added compounding ingredients of such nature and quality that the finished pr
24、oduct complies with thespecification requirements. In permitting a choice in use of materials by the manufacturer, it is not intended to imply that thedifferent materials are equivalent in respect to all physical properties. Any special characteristics, other than those prescribed inthis specificati
25、on, which may be desired for specific applications shall be designated in the product specifications as they mayinfluence the choice of the type of poly(vinyl chloride) or other ingredients used. All materials and workmanship shall be inaccordance with good commercial practice and the resulting prod
26、uct shall be free of defects affecting serviceability.7.2 Due to manufacturing conditions, material may have to be altered or repaired. This repaired or altered material will beacceptable under this specification provided the material used in such repairs or alterations shall be of the same composit
27、ion andquality as the original product and provided such alterations do not affect the serviceability, size, and shape beyond the tolerancesprovided herein.8. Color8.1 Unless otherwise specified, the color of the material shall be optional with the manufacturer.9. Sampling9.1 When possible the compl
28、eted manufactured product shall be used for the tests specified. Representative samples of the lotbeing examined shall be selected at random as required.9.2 When it is necessary or advisable to obtain test specimens from the article, as in those cases where the entire sample is notrequired or adapta
29、ble for testing, the method of cutting and the exact position from which specimens are to be taken shall bespecified. The apparent density and the state of fusion could vary in different parts of the finished product, particularly if the articleis of complicated shape or of varying thickness.These f
30、eatures affect the physical properties of the specimens.The apparent densityis affected by the number of cut surfaces as opposed to the number of skin-covered surfaces on the test specimen.9.3 When the finished product does not lend itself to testing or to the taking of test specimens because of com
31、plicated shape,small size, metal or fabric inserts, adhesion to metal, or other reasons, suitable test slabs shall be prepared as agreed between theTABLE 2 Tolerances on Dimensions of Closed Cell VinylProductsThickness, mm (in.)

Physical Properties10.1 The various grades of closed-cell vinyl shall conform to the requirements as to basic physical properties prescribed in Table1, together with any additional requirements indicated.11. Test
34、 Methods11.1 Unless specifically stated otherwise, make all tests in accordance with the methods specified in Section 14.12. Inspection and Rejection12.1 All tests and inspection shall be made at the place of manufacture prior to shipment, unless otherwise specified.12.2 The purchaser reserves the r
35、ight to make the tests and inspection for acceptance or rejection of the material at the laboratoryof his choice.12.3 Any material that fails in one or more of the test requirements shall be retested. For this purpose, two additional tests shallbe made for the requirement in which failure occurred.
36、Failure of either of the tests shall be cause for final rejection.12.4 Rejected material shall be disposed of as directed by the manufacturer.13. Packaging and Package Marking13.1 The material shall be properly and adequately packaged. Each package or container shall be legibly marked with the nameo
37、f the material, name or trademark of the manufacturer, and any required purchasers designations.14. General Test Methods14.1 The following tests shall be applicable in the physical testing of closed cell poly(vinyl chloride) or copolymers thereof:14.1.1 Compression DeflectionTest method described in
38、 Sections 16 20.14.1.2 Compression Set Under Constant DeflectionTest method described in Sections 21 25.14.1.3 Water AbsorptionTest method described in Sections 26 30.NOTE 3Additional test methods are listed in the appendix.15. Measurement of Test Specimens15.1 The length and width shall be measured
39、 with a steel scale or tape. Care shall be taken not to distort the material.15.2 Thicknesses up to and including 25 mm (1 in.) shall be measured using a dial-type gagegauge having a maximum stemand foot mass of 25 g and a foot 32 mm (1.25 in.) in diameter, taking care not to compress the specimen.
40、Thicknesses over 25mm (1 in.) shall be measured using a sliding caliper gage or as specified in 15.1. When a sliding caliper gage is employed the gagesetting shall be made with the gage out of contact with the closed cell vinyl. The specimen shall be passed through the previouslyset gage, and the pr
41、oper setting shall be the one when the measured faces of the gage contact the surfaces of the article withoutcompressing it.15.3 The steel scale or tape used to measure length or width shall be graduated in divisions not over 1 mm (0.031 in.). The dialgage for measuring thickness shall be graduated
42、in divisions not over 0.02 mm (0.001 in.). The calipers used for measuringthickness shall be graduated in divisions not over 0.1 mm (0.005 in.).15.4 Results reported shall be the average of a minimum of three measurements.COMPRESSION DEFLECTION TEST METHODCOMPRESSION DEFLECTION TEST METHOD16. Scope1
43、6.1 This test consists of measuring the force necessary to produce a 25 % deflection on a 650-mm645.16-mm2 (1-in.2) testspecimen.17. Apparatus17.1 The apparatus used for this test shall have a flat indentor foot, larger than the specimen being tested, connected to aforce-measuring device, and mounte
44、d in such a manner that the specimen shall be deflected at a rate between 0.2 and 0.8 mm/s(0.5 and 2.0 in./min). The apparatus shall be arranged to support the specimen on a level, horizontal plate.D1667 17418. Test Specimens18.1 The specimens shall be cylinders 650 mm28.67 6 0.50 mm in diameter, wh
45、ich yields 645.16 6 0.20 mm2 (1 in.2) in areawith parallel top and bottom surfaces. They shall be cut so that opposite edges are parallel, either from the finished product in amanner agreed upon between the manufacturer and the purchaser, or from standard test slabs, or from commercial flat sheets.
46、Thethickness of the test specimens shall be measured and stated in the report. Maximum thickness shall be 2525.4 mm (1.0 in.). Thespecimens shall be cut with either a revolving die or oscillating cutter. Use a soap solution if a lubricant is needed. If a lubricantis used, the specimen shall be thoro
47、ughly dried before proceeding with the testing. In some cases, it may be necessary to freezethe cellular vinyl to obtain parallel cut edges.NOTE 4Other specimen sizes can be used as agreed upon between user and supplier.19. Procedure19.1 Test closed-cell vinyl (grades VE-40 to VE-45) samples less th
48、an 6.0 mm (0.236 in.) in thickness by plying up to obtaina thickness as near 12.512.7 mm (12 in.) as possible. Deflect the specimen 25 % of its original height. Maintain the deflection at25 % with automatic or manual control and record the force in newtons or pounds force 6060 6 1 s after the 25 % d
49、eflection isreached. The result obtained in this test is influenced by temperature, and tests that are to be compared shall be conducted undersubstantially the same temperature. In all cases, report the actual temperature during the test.19.2 In case of dispute perform the test at a temperature of 23 6 1C2C (73.4 6 1.8F).3.6F). Condition the specimenundeflected and undistorted at this temperature for at least 12 h before testing. Ordinarily only one test shall be made, but in caseof dispute express the result as the averag
