ASTM D3394-1994(2009)
Standard Test Methods for Sampling and Testing Electrical Insulating Board
适用范围：<p>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.</p><p id="s00002">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. </p> <p id="s00003">1.2 These test methods are not intended for testing vulcanized fibre or molded laminated sheets.</p> <p id="s00004">1.3 These test methods are applicable to board materials having a nominal thickness of at least 0.030 in. (0.76 mm). <p class="desc" id="N00001"> <span class="smallcap">Note</span> 18212;For materials thinner than 0.030 in. (0.76 mm) see Test Methods <a href="http://myastm.astm.org/SUBSCRIPTION/NewValidateSubscription.cgi?D202-HTML">D202</a>.</p>
