Standard Practice for Sampling and Judging Quality of Solid Electrical Insulating Materials
ABSTRACT
This practice covers procedures for obtaining data on the quality of solid electrical insulating materials and for judging whether the materials meet the requirements specified. This practice, however, is not intended to define internal quality control procedures of the producer; rather, it is designed to determine the acceptability of all, or some portion, of a quantity of electrical insulating materials available for inspection by the user of the material. In addition, this practice is intended for use in conjunction with existing material specifications including property characteristic limits, acceptable quality level, standard test methods, and sampling instructions. Data shall be obtained by taking lot samples randomly. Sampling plans are available in single, double, and multiple types. Acceptable quality levels for each critical, major, and minor property as well as inspection levels shall conform to the requirements specified. Acceptance of lot quality shall be determined based on the comparison of test results and other information obtained using the sampling plans with the requirements set forth in the material specification (nonconformity) and on whether the lot meets the requirements specified.
SCOPE
1.1 This practice covers procedures for obtaining data pertaining to the quality of a lot of electrical insulating material and for making a judgement whether the lot meets the requirements of a material specification.
1.2 This practice is not intended to define a producer's internal quality control procedures but is designed to determine the acceptability of all, or some portion, of a quantity of electrical insulating material that is available for inspection by the user of the material.
1.3 This practice is intended to be used in conjunction with an existing material specification that specifies property characteristic limits, acceptable quality level (AQL), standard test methods, and specific sampling instructions.
1.4 In the absence of a specification as described in 1.3, use this practice as a guide, after establishment of agreed-upon property characteristics, limits, AQL, standard test methods, and specific sampling instructions.
1.5 It is intended that this be a practice for inspection by attributes.
1.6 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.
1.7 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
