ASTM D3394-16

Standard Test Methods for Sampling and Testing Electrical Insulating Board

SIGNIFICANCE AND USE
19.1 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.
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 D202.
