1、Designation: F30 96 (Reapproved 2012)Standard Specification forIron-Nickel Sealing Alloys1This standard is issued under the fixed designation F30; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of last revision.Anumber in
2、 parentheses indicates the year of last reapproval.Asuperscriptepsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers iron-nickel alloys that areintended primarily for sealing to glass in electronic applica-tions.NOTE 1Some of these alloy
3、s may be used for sealing to ceramics, butthis specification in its present form is not intended to cover material formetal-to-ceramic seals.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provi
4、ded for information onlyand are not considered standard.1.3 This standard does not purport to address the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regul
5、atorylimitations prior to use. The hazard statement pertains only tothe test method sections, Sections 10 and 12.2.
