EIA-364-36B:2006 (R2013)

This procedure is to determine the integrity of contacting surfaces (at the mating and/or termination areas) by assessment of the gas tight characteristics of the contacting surfaces. The gas tight characteristic simulates the ability of the contacting surfaces to prevent harsh environments from penetrating between them and forming oxides and/or films that will degrade electrical performance. It is recommended for contacts and/or connector (socket) assemblies directly exposed to outside environments or those that are in uncontrolled environments (internal or external to electronic packaging). CAUTION- The method, as described herein, utilizes nitric acid vapors. This procedure may involve hazardous materials, operations and equipment. This procedure does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of the standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations before its use.
