1.1 This test method includes several procedures that can be used for the measurement of overall package and seal barrier performance of a variety of package types and package forms, as well as seal/closure types. The basic elements of this method include: 1.1.1 Helium (employed as tracer...
This SAE Standard provides the testing and functional requirements guidance necessary for a leak detection device that uses any non-A/C refrigerant tracer gas, such as helium or a nitrogen-hydrogen blend, to provide functional performance equivalent to a refrigerant electronic...
The system emissions chart contained herein is intended to serve as a means of estimating the annual refrigerant emission rate (grams per year) from new production A/C systems equipped with specified component technologies. It provides emission values for various component technologies that are...
6.1 Test Method A is the most frequently used in leak testing components which are structurally capable of being evacuated to pressures of 0.1 Pa (approximately 10-3 torr). Testing of small components can be correlated to calibrated leaks, and the actual leak rate can be...
This specification covers tantalum and tantalum alloy seamless and welded tubes of the following grades: UNS Grade R05400 which is unalloyed tantalum, powder-metallurgy consolidation, UNS Grade R05200 which is unalloyed tantalum, vacuum melted, UNS Grade R05252 which is tantalum with 2.5% tungsten...
5.1 Test Method A-This test method is the most frequently used in leak testing components. Testing of components is correlated to a standard leak, and the actual leak rate is measured. Acceptance is based on the maximum system allowable leakage. For most production needs,...
6.1 Methods A or B are useful in testing hermetically-sealed devices with internal volumes. Maximum acceptable leak rates have been established for microelectronic devices to assure performance characteristics will not be affected by in-leakage of air, water vapor or other contaminants over...
