In order to provide a balanced panel andprevent field warpage, the two asbestos-cement facings shouldhave essentially equal vapor transmission rates.5. Physical Properties5.1 Facing

16、sAsbestos-cement facing sheets shall conformto the requirements for Type F of Specification C220 for3.2-mm (18-in.) thickness.5.2 CoreThe plastic-foam core as well as pertinent gradeor type classification shall be as agreed upon by the purchaserand seller. If Urethane is used, it shall conform to th

17、erequirements of Specification D2341.5.3 Strength PropertiesThe average breaking load forpanel specimens conditioned for seven days at 23 6 2C (70 to77F) and 50 6 10 % relative humidity shall not be less thanthat shown in Table 1.5.4 Vapor PermeabilityThe vapor permeance of the com-posite panel is d

18、ependent not only on the foam core, but on theadhesive, facing sheets, and the coating on such facings.

20、.6. Dimensional Measurements6.1 SignificanceThese are routine measurements for thepurpose of determining whether the length and width of theindividual units are as ordered, to ensure that they fit togetherproperly in application, and to determine the uniformity of thespecified thickness.6.2 Procedur

21、eMeasure each test specimen for thickness,using a micrometer caliper having flat anvils approximately 6.4mm (14 in.) in diameter and reading to 0.0254 mm (0.001 in.).Make four measurements on each specimen at the approximatemidpoint of each edge of the specimen, and at least 12.7 mm(12 in.) in from

22、the edge. Average the four measurements, andrecord as the specimen thickness.7. Dimensions, Mass, and Permissible Variations7.1 Asbestos-cement plastic-foam core panels are normallysupplied in the commercial dimensions given in Table 4.However, because of the frequent use of other thicknesses, thesc

23、ope of this specification is not limited to only the morecommon thicknesses.7.2 Permissible Variation in Dimensions:7.2.1 ThicknessThe permissible variation of any indi-vidual panel from the nominal thickness shall be 61.2 mm (364in.).7.2.2 Width and LengthThe permissible variation of anyindividual

24、panel from the nominal length and width shall be63.2 mm (18 in.) and 61.6 mm (116 in.), respectively, asmeasured after 48 h at 23 6 2C (70 to 77F) and 50 6 5%relative humidity.7.2.3 SquarenessThe deviation from squareness shall notexceed 1.3 mm/m (164 in./ft) of width or length. The recom-mended too

25、ls for measuring squareness are a feeler gage andmetal carpenter square.8. Workmanship, Finish, and Appearance8.1 WorkmanshipPanels shall have a commercially ac-ceptable surface on both sides and be free of major defects thatwill impair appearance, erection, use, or serviceability.8.2 FinishThe surf

26、ace on both sides of the panel may besmooth, grained, granuled, coated, or otherwise textured asspecified by the purchaser.8.3 ColorBoth surfaces of the panel will be the naturalcolor of the asbestos-cement product or may be colored by theaddition of mineral pigments, chemical impregnation, pig-ment

27、ed coatings, veneers, or embedded mineral granules asspecified by the purchaser.9.

31、cimens 305 by 760 mm (12by 30 in.), from each panel to be tested, with the longdimension of the samples parallel to the long dimension of thepanel. Condition each specimen for seven days at 23 6 2C (70to 77F) and 50 6 10 % relative humidity. Determine theflexural strength of each specimen by placing

32、 the specimen onsupports that do not exert longitudinal constraint (rocker-typebearing edges or rollers witha3mm(18 in.) minimum and a13 mm (12 in.) maximum radius) and applying the load equallyand simultaneously at both one-third points of the span throughsimilar edges bearing against either surfac

Increase the load applied ata uniform rate to produce a failure of the specimen in 1 to 2min. The error in the load reading shall not exceed 1 % of themaximum load. Report the flexura

34、l strength as the averagebreaking load, in newtons (or pounds-force), for all thespecimens tested.10.1.2 Warningsee .10.2 Vapor Permeability:10.2.1 SignificanceThe purpose of this test method is toobtain, by means of simple apparatus, reliable values inuniform units of measurement for the rate of wa
