1.1These 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.
1.2These test methods are not intended for testing vulcanized fibre or molded laminated sheets.
1.3These 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 D202.
1.4The test methods appear in the following sections:
| | ASTM Method | |
| Apparent Density | 18 – 23 | |

1.5The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.6This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
