InterTest offers cost effective solutions to hermetic seal testing products which exceed Mil-Std-883 requirements, as well as less stringent requirements of Mil-Std-750 & Mil-Std-202 and . Mil-STD-883 Test Method 1014 (REF 1) is the universally accepted test designed to determine the effectiveness or hermeticity of the seal. There are several techniques for testing hermeticity, but the most common method is to measure the rate at which helium escapes from a package that has been pressurized or backfilled with helium (the tracer gas).
significant one is the splitting the document into test methods. See MIL-STD-202 for the change summary. 3.

the process and in all these schedules with E-10 air leak rates; no gross leakers resulted. The Test Method 1014 seal requires gross leak testing to occur within 1 hour from sealed packages removal from the helium bombing process. Per Figure 8, gross leakers are identified in a number of ways including when a high percentage of helium is detected.
an overview of hermetic sealing processes and then examines the accepted leak test techniques as prescribed in MIL-STD-883 Test Method 1014. Issues with bomb times and pressures, measured leak rate vs. air leak rates, “one way leakers”, virtual leakers will be addressed, along with gross leak testing.
