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 | |
| Aqueous Extract Characteristics | 36 – 42 | D202 |
