| Significance and Use | ||||||||||||||||||||||||||||||||||||||||||||||
|
Apparent density affects the dielectric and physical characteristics of insulating board and is a factor in the economics of its use in apparatus. This test is useful for specification, design, and quality control purposes. |

| 1. Scope | ||||||||||||||||||||||||||||||||||||||||||||||
|
1.1 These test methods cover the sampling and testing of electrical insulating boards. These boards are porous, usually fibrous sheets used for dielectric and structural purposes in electrical apparatus. 1.2 These test methods are not intended for testing vulcanized fibre or molded laminated sheets. 1.3 These test methods are applicable to board materials having a nominal thickness of at least 0.030 in. (0.76 mm). Note 1 For materials thinner than 0.030 in. (0.76 mm) see Test Methods D 202. 1.4 The test methods appear in the following sections: 1.5 The values stated in inch-pound units are to be regarded as the standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
