ASTM F18-12<\/h3>\n

Historical Standard: Standard Specification and Test Method for Evaluation of Glass-to-Metal Headers Used in Electron Devices<\/h4>\n
\n

ASTM F18<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This specification and test method cover acceptance requirements for headers used in electron devices and describes procedures for determining conformance to these requirements.<\/p>\n

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.<\/p>\n

1.3 The following safety hazard caveat pertains only to the test method (Sections 7-13) described in this specification.<\/span> 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 and health practices and determine the applicability of regulatory limitations prior to use.<\/span><\/span><\/p>\n
