1、Designation:D337614Standard Test Methods ofSampling and Testing Pulps to be Used in the Manufactureof Electrical Insulation1This standard is issued under the fixed designation D3376;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the
2、 year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 These test methods cover the sampling and testing ofcellulosic pulps for use in the manufacture of electricalinsu
3、lating papers and boards or in the direct application of pulpfibers as insulation to electrical conductors.NOTE1The significance of any one pulp property test method,as setforth herein,should be considered with discretion depending on theproduct made from the pulp.1.2 Sections on Reagents,Sampling,a
4、nd Report are integralparts of each of the individual test methods that follow.1.3 Each test method is described as being a measure ofeither a bulk property of the pulp or a property of a handsheetformed from the pulp.1.3.1 Bulk characteristics determinable by these proceduresappear in the following
