36、he number of seconds needed to ignite a specimen (nished component) by a bar that dissipates a specied level of electrical energy as described in the requirements for television receivers and video products, UL 1410. b Resistance to Ignition-Hot-Wire Hot-wire ignition performance is expressed as the
37、 number of seconds needed to ignite standard specimens that are wrapped with resistance wire that dissipates a specied level of electrical energy. Bar samples as described in note c are to be used during this test. This test is described in the Standard for Polymeric Materials Short Term Property Ev
38、aluations, UL 746A. c Flammability Classication Determined by tests described in the Standard for Tests for Flammability of Plastic Materials for Parts in Devices and Appliances, UL 94. For testing a material, the samples are to be at stock (bar samples) approximately 5 inches (130 mm) long by 1/2 i
39、nch (13 mm) wide, and of the smallest thickness used; for an assembly, the samples can consist of the assembly. High-voltage transformers, deection yokes, printed-wiring boards, terminal strips, and the like can be tested as nished parts, or test samples can be cut from nished parts. In the case of
40、small parts that might be consumed before the test is completed, large samples of the same material can be tested provided they represent the same or lesser thickness than the part in question. None of the larger samples is to be entirely consumed. Samples that consist of an assembly or a section th
41、ereof that are not at stock samples are to be positioned in what is considered to be the worst position in the application. The parts evaluated by Table 11.1 and classied using 1/16 inch (1.6 mm) thick bar specimens may be accepted in lesser thicknesses in the end product. d Dielectric Breakdown Str
42、ength At least 175 volts per mil as determined in accordance with the Standard Test Method for Dielectric Breakdown Voltage and Dielectric Strength of Solid Electrical Insulating Materials at Commercial Power Frequencies, ASTM D 149-97A, after conditioning for 96 hours at 35C (95F) and 90 percent re
43、lative humidity as described in Procedure C in the Standard Practice for Conditioning Plastics and Electrical Insulating Materials for Testing, ASTM D 618-96. These are minimum values usually characteristic of the majority of materials classied as insulators. Higher values might be needed to perform
44、 acceptably in the end product. See note n for information regarding effective date of note d e Volume Resistivity 50 megohms-centimeter as measured after conditioning for 40 hours at 23.0C (73.4F) and 50-percent relative humidity as indicated in Procedure A of the Standard Practice for Conditioning
45、 Plastics and Electrical Insulating Materials for Testing, ASTM D 618-96 and 10 megohms-centimeters after being conditioned for 96 hours at 35C (95F) and 90 percent humidity as indicated in Procedure C, conducted in accordance with the Standard Test Methods for DC Resistance or Conductance of Insula
46、ting Materials, ASTM D 257-93. These are minimum values usually characteristic of the majority of materials classied as insulators. Higher values might be needed to perform acceptably in the end product. See note n for information regarding effective date of note e f Heat Distortion Temperature When
47、 measured at 66 pounds per square inch (4.64 kg/cm 2 ) the heat distortion temperature shall not be less than 10C (18F) more than the maximum operating temperature of the material in the appliance when tested as described in the Standard Test Method for Deection Temperature of Plastics Under Flexura
48、l Load, ASTM D 648-98C. Materials having a heat distortion temperature less than this can be considered on the basis of the results of the 7 hour oven test used to evaluate the effects of mold-stress relief. See note n for information regarding effective date of note f g Mold-Stress Relief The part
49、is required to withstand a temperature-stability test or, at the manufacturers option, an oven test as described in the requirements for television receivers and video products, UL 1410. There is to be no shrinkage, warpage or other distortion that: 1) Interferes with intended operation or servicing, 2) Results in accessibility of live parts or 3) Reduces electrical spacings below the level necessary to comply with the applicable requirements pertaining to dielectric strength a
