1.1These 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.

1.2Sections on Reagents, Sampling, and Report are integral parts of each of the individual test methods that follow.

1.3Each 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.

1.4The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5This 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.

1.6This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
