1.1''This practice covers the preparation of insulating paper and board impregnated with a liquid dielectric. Where this practice states only '''paper,''' the same procedure shall apply to board.

1.2''This practice has been found practicable for papers having nominal thickness of 0.05 mm (2 mil) and above. It has been used successfully for insulating board as thick as 6 mm (¹/₄''in.) when care is taken to ensure the specimen geometry necessary for valid measurement of dielectric properties. Suitable geometry depends on the electrode system used. Rigid solid opposing electrodes require flat specimens that have essentially parallel surfaces.

1.3''The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4''This 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.
