MIL-STD-883 method 2004.7 – Test condition A: Tension
Purpose
This test is designed to check the capabilities of the device leads, welds, and seals to withstand a straight pull.
Apparatus
The tension test requires suitable clamps and fixtures for securing the device and attaching the specified weight without lead restriction. Equivalent linear pull test equipment may be used.
Procedure
A tension of 0.227 kg (8 ounces), unless otherwise specified, shall be applied, without shock, to each lead or terminal to be tested in a direction parallel to the axis of the lead or terminal and maintained for 30 seconds minimum. The tension shall be applied as close to the end of the lead (terminal) as practicable.
Failure criteria
When examined using magnification between 10X and 20X after removal of stress, any complete breakage (e.g. separation of the lead from the body) or loosening of the lead at the glass/ceramic seal that has caused a method 1014 seal failure shall be considered a failure. When a seal test in accordance with method 1014 is conducted as a post test measurement following the lead integrity test(s), meniscus cracks shall not be cause for rejection of devices which pass the seal test.
Summary
The following details shall be specified in the applicable acquisition document:
