This standard applies generally to gas proportional instruments and the use thereof in measuring materials with an alpha emissivity of less than 10 a·khr^-1·cm^-2.  The primary focus will be on materials used in semiconductor fabrication.  The purpose of this document is to specify the recommended method for measuring alpha emissivity in materials utilized in the manufacturing of semiconductors. The method specifically applies to gas proportional instruments and designates recommended instrument settings. In addition, the method discusses operation of ionization counters. The document also recommends methods for determining sample size and for evaluating instrument background accurately.

The method described in this document applies to all application specific reliability testing for solid state components with known failure mechanisms where the test duration and conditions vary based on application variables. This document does not cover reliability tests that are characterization based or essentially go / no-go type tests, for example, ESD, latch-up, or electrical over stress. Also, it does not attempt to cover every failure mechanism or test environment, but does provide a methodology that can be extended to other failure mechanisms and test environments.
