Test Methods39.1 The properties enumerated in this specification shall be determined in accordance with the following methods:9.2 Impact Resistance (Izod)Test Method D256, Method A. Test specimens shall be 12.7 by 12.7 by 63.5 mm.9.3 Flexural StrengthTest Methods D
27、790 Procedure A. Test specimens shall be 6.4 by 12.7 by 127-mm bars tested parallelto molding pressure.9.4 Permittivity and Dissipation FactorTest Methods D150. Measure the permittivity and dissipation factor at 1 kHz and 1MHz after conditioning by Procedure B of Practice D618. Determine permittivit
28、y and dissipation factor after conditioning 48 hat 50C followed by Procedure D of Practice D618. Use 102 by 3.2-mm disks for 1 kHz frequency and 51 by 3.2-mm disks for1 MHz frequency.9.5 Insulation ResistanceTest Methods D257, using a 3.2-mm thick by 102-mm diameter disk fitted with binding postelec
29、trodes of the type shown in the figure illustrating Binding-Post Electrodes for Flat, Solid Specimens of Test Methods D257.Cut two sections from the disk so that the section under test is similar to the figure cited above. Scrub with soapy water, rinse indistilled water, and rinse with isopropyl alc
30、ohol. Air dry the sample before assembly, using stainless steel terminals which havebeen washed in isopropyl alcohol. The use of clean cotton or polyethylene gloves during assembly is required since skin oilscontaminate the plastic surface and have been shown to seriously affect results. Insert one
31、binding post through a hole drilledthrough the center of the disk. Space the other two electrodes 32 mm from the center electrode. Make test measurements betweenthe center electrode and each of the other binding posts. The machine screw and washers shall be of stainless steel, the screw ofa size to
32、match the washer size specified in the figure illustrating Binding-Post Electrodes for Flat, Solid Specimens of TestMethods D257. Two specimens may then be mounted in a wide-mouth jar with the leads going through a TFE-fluorocarbon cover.Condition each specimen 720 h at 60C and 95 % relative humidit
33、y, and measure the insulation resistance under the sameconditions without removal from the environmental chamber.9.6 Flame ResistanceMethod II under Flame Resistance of Test Method D229. The specimen shall be 12.7 by 12.7 by 127mm.9.7 Oxygen IndexTest Method D2863. Test specimens shall be 3.2 by 6.4
34、 by 127 mm.10. Inspection10.1 Inspection of the compound shall be agreed upon between the purchaser and supplier as part of the purchase contract.11. Rejection and Rehearing11.1 Compound that fails to conform with the requirements of this specification may be rejected. Rejection should be reportedto
35、 the producer or supplier promptly and in writing. In case of dissatisfaction with the results of the test, the producer or suppliermay make claim for a rehearing.NOTE 4In the case of short shelf-life materials it is the responsibility of the purchaser to expedite the tests and to keep the material
36、at optimum storageconditions until returned in case of failure.12. Packaging and Package Marking12.1 PackagingThe compound shall be packaged in standard commercial containers so constructed as to ensure acceptanceby common or other carriers for safe transportation at the lowest rate to the point of
37、delivery, unless otherwise specified in thecontract or order.12.2 Package MarkingShipping containers shall be marked with the name of the compound, type, class, grade, color lot orbatch number, limiting shelf-life data in common storage, the quantity contained therein as defined by the contract or o
38、rder, andthe name of the manufacturer or his trademark.12.3 All packing, packaging, and marking provisions of Practice D3892 shall apply to this specification.13.
