Abstract
These test methods cover procedures for testing fully cured silicone rubber-coated glass fabric and tapes to be used for electrical insulation. The test procedures for the following test methods are detailed: (1) breaking strength, (2) breaking strength after creasing, (3) dielectric breakdown voltage, (4) dielectric proof voltage, (5) dissipation factor and relative permittivity, (6) thermal endurance, (7) thickness, (8) thread count, (9) volume resistivity, and (10) weight. The procedures for sampling of fabric rolls, fabric sheets, tapes and strips, and test specimen preparation and conditioning are given. The test apparatus, report requirements, and precision and bias for each test are provided. The drum type gripping device and creasing apparatus for breaking strength test are illustrated. Voltage stress test shall be done for dissipation factor and relative permittivity and volume resistivity tests.
