Standard Test Methods of Sampling and Testing Pulps to be Used in the Manufacture of Electrical Insulation
1.1 These test methods cover the sampling and testing of cellulosic pulps for use in the manufacture of electrical insulating papers and boards or in the direct application of pulp fibers as insulation to electrical conductors.
Note 1: Consider the significance of any one pulp property test method, as set forth herein, with discretion depending on the product made from the pulp.
1.2 Sections on Reagents, Sampling, and Report are integral parts of each of the individual test methods that follow.
1.3 Each test method is described as being a measure of either a bulk property of the pulp or a property of a handsheet formed from the pulp.
1.3.1 Bulk characteristics determinable by these procedures appear in the following sections:
1.3.2 Handsheet characteristics determinable by these procedures appear in the following sections:
Note 2: Methods for Ash, Silica, selected cations from Ash, Heat Stability, α, β, and γ Cellulose, Viscosity, Total Chlorine, Tear, and Dissipation Factor and Relative Permittivity, will be considered for addition as methods are developed.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 This 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 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
