The edges shall be free ofnicks and cuts visible to the unaided eye.5.2 Dimensions:5.2.1 SizeThe nominal thickness, width, and length of thesheeting in each roll shall be agreed upon between th

17、e buyerand the seller.5.2.2 Tolerances:5.2.2.1 ThicknessThe thickness at any point, when mea-sured in accordance with 8.5, shall not be less than 80 % of thenominal thickness.5.2.2.2 WidthThe tolerance for widths of 0.3 m (1 ft) ormore, shall be 3.2 mm (18 in.) per foot of nominal width. Forall widt

18、hs less than 0.3 m (1 ft), the tolerance shall be 3.2 mm(18 in.). Width to be measured in accordance with 8.6.5.2.2.3 LengthThe length of sheeting per roll, whenmeasured in accordance with 8.6, shall be within + 3 %to1%ofthelength specified.5.2.3 Minimum Net WeightThe actual net weight of eachroll s

19、hall be not less than the nominal net weight, whendetermined in accordance with the formula established in 8.7.The nominal net weight shall, in turn, be the labeled netweight.6. Detail Requirements6.1 Color and FinishThe sheeting may be natural, (essen-tially colorless), color tinted, translucent, o

20、r opaque. Thesurface finish may be plain, printed, or otherwise treated asagreed upon between the buyer and the seller.6.2 Impact ResistanceThe average impact resistance shallbe not less than the resistance specified in Table 1, when testedin accordance with 8.8.6.3 Mechanical PropertiesThe average

21、tensile strengthand elongation at break for all thicknesses of sheeting shall beas specified in Table 2, when tested in accordance with 8.9.6.4 ReflectanceThe daylight reflectance of white opaquesheeting, intended for use in curing concrete, shall be not lessthan 70 %, when determined in accordance

22、with 8.10.6.5 Luminous TransmittanceBlack sheeting intended forexclusion of light and for maximum resistance to weatheringshall have an average luminous transmittance not greater than1 %, when determined in accordance with 8.11. This low levelof luminous transmittance indicates a high degree of opac

23、ity.6.6 Water Vapor Transmission Rate (WVTR)The averagewater vapor transmission shall not be greater than 22.0g/m2(1.40 g/100 in.2) per 24 h for sheeting 25 m (1 mil) inthickness, when determined in accordance with 8.12. Thewater vapor transmission rate is inversely proportional to thethickness. Max

24、imum limits for rate of water transmission as afunction of thickness are given in Table 3. Equivalent maxi-mum limits in terms of permeance are given in Table 4.Itshould be noted that the WVTR requirement is not necessaryfor all applications (such as pallet wrap). However, Table 3 andTable 4 may be

25、used for those cases where the WVTR is animportant consideration.7. Sampling7.1 Samples for test purposes shall be taken from rolls,selected at random from the total number of rolls in eachshipment or lot, in accordance with Table 5.7.2 The samples for testing shall be full width and shall becut at

26、least three full turns, but not less than 1.5 m (5 ft), fromeither end of the sheeting on each roll. Normally about 2 m2(20ft2) of sheeting is needed to carry out all the tests.All the testsshall be made on each sample roll. Rolls damaged in shipmentshall not be selected for testing.7.3 The specimen

27、s to be used for a particular test shall becut from different parts of the sheeting sample (that is, theyshall not be cut adjacent to one another), unless otherwisespecified in the test.8. Test Methods8.1 GeneralThe tests given herein are intended primarilyfor use as production tests in conjunction

28、with manufacturingprocesses and inspection methods to insure conformity ofsheeting with the requirements of this specification.8.2 Production Inspection and Testing During the processof manufacture, the manufacturer shall make inspections andTABLE 1 Dart Drop Impact ResistanceANominal Thickness, m (
