19、(23 kg) of each of the two liquid components asrequired to prepare the foam test specimens specified inSection 9. Samples may be drawn from representative bulkstorage or from one or more shipping containers.8.3 Sampling for qualification tests, if required, shall be inaccordance with statistically s

20、ound practice. Qualification testswill be conducted on the physical properties in Table 1.8.4 Sampling for inspection tests, if required, shall be forproperties agreed upon between the manufacturer and thepurchaser.9. Test Specimen Preparation9.1 Finished polyurethane foam insulation test panels sha

21、llbe made by spray application consistent with the manufactur-ers recommendations including: temperatures of the liquidcomponents, ambient temperature, temperature and type ofsubstrate, type and operation of spray equipment, and thicknessof foam per pass. Unless otherwise specified and reported, the

22、ambient and substrate temperature shall be 75 6 5F (24 63C). The relative humidity must not exceed 80%. The testpanels shall be of a sufficient quantity and size to satisfy testrequirements.NOTE 3Specific panel sizes and thicknesses shall be based on therequirements of the individual tests.9.2 The t

23、est panels shall be allowed to cure for at least 72 hat 73 6 2F (23 6 1C) and 50 6 5% relative humidity priorto cutting or testing for physical properties.9.3 Core specimens, when required, shall be obtained byremoving both the external skin and the boundary skin found atthe substrate/foam interface

24、.Atrim cut on each face to a depthof18 to14 in. (3 to 6 mm) is generally sufficient. Corespecimens may contain one or more internal skins at spray passboundaries.9.4 For Type III products the samples are spray applied toExterior CDX Grade34 in. (19-mm) plywood (unfinished onboth sides), which is 2 f

25、t by 2 ft. (610 by 610- mm). Themaximum height of the applied foam shall be 2 in. (50-mm)above the substrate with a minimum of 2 passes and amaximum of 3. A sample of 12 in. x 12 in. (305 by 305-mm)is cut from the center of the plywood foam sample as the testspecimen. The specimen and plywood will b

26、e cut in such amanner that it will have a nit line. The cut foam height will be1 in. from the plywood surface. The test specimen will be cutfrom the field sample so as to have smooth edges free ofcracks. All faces will be smooth. Dust shall be blown off thesample. Two specimens shall be used for tes

27、t exposure per test.In addition, 2 samples of the plywood will also be cut 2 in. x12 in. (305 by 305-mm) as a control. For other product typesdetermine the response to thermal and humid aging on foamcore samples of 12 in. x 12 in. (305 by 305-mm).10. Test Methods10.1 Determine thermal resistance in

General InformationX1.1 The properties of spray-applied polyurethane thermalinsulation may vary depending on such factors as the thicknessof the foam sprayed, the tempe

43、rature and type of substrate, theambient temperature and humidity, the number of spray passes,and the output of the equipment. The properties may also varydepending on different manufacturers liquid components.X1.2 Spray-applied polyurethane thermal insulation gener-ally exhibits its highest thermal

44、 resistance at the time ofmanufacture. The thermal resistance may be significantlyinfluenced by installation and service-related variables such asage, foam thickness, type of coating, environmental conditionsand mechanical abuse. These variables may cause the thermalresistance to be reduced from mea

45、sured initial values.X1.3 The application of a suitable vapor retarder may berequired in conjunction with this insulation. In exterior instal-lations, coatings or coverings are necessary for protection fromC1029083the elements and should be applied on the same day.X1.4 Rigid-cellular polyurethane th

46、ermal insulation iscombustible to varying degrees when exposed to an ignitionsource or high temperatures, or both. In interior installations,the polyurethane thermal insulation shall be covered by anapproved thermal barrier the same day it is spray applied.3X1.5 Consult local building and fire code
