A rigorous test case based approach is often traditional for large software engineering projects that follow a Waterfall model. [2] However, at least one recent study did not show a dramatic difference in defect detection efficiency between exploratory testing and test case based testing. [3] Testing can be through black-, white-or grey-box ...
The usage of TB 2 is deprecated since the 2006 edition of the standard, which prescribes that cards should not include TB 2 in the ATR, and readers shall ignore TB 2 if present. In the 1997 edition of the standard, TB 2 (8th to 1st bit) encode PI2, which when in range 50..250 (other values being RFU) encode V PP in increments of 0.1 V, and ...
An LCR meter is a type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component. [1] In the simpler versions of this instrument the impedance was measured internally and converted for display to the corresponding capacitance or inductance value. Readings should be reasonably ...
Some service testers include a go/no-go feature, indicating a pass when a certain h fe is exceeded. These are useful, but fail some functional but low h fe transistors. Some also provide a means of identifying transistor elements, if these are unknown. The tester has all these features and can check solid-state devices in and out of circuit.

It has been used in testing the F-14, S-3, E-2, A-7 Corsair II, A-6, etc. VAST is considered by many to be the grandfather of modern avionics test equipment. In the years that followed the cold war, ATLAS found uses on many dual-use aircraft [ clarification needed ] for the U.S. and NATO , as well as commercial business, regional, and general ...
For explosive devices, test requirements and methods are tailored from MIL-HDBK-1512 and NATO AOP-7. For batteries, guidance on test requirements is in RCC-Doc-319-99. Note: Surveillance Testing is a periodic repeat of the Acceptance Testing using trending or accelerated aging to authorize shelf life extensions.
While in the traditional static tests the test force is applied uniformly with increasing magnitude, dynamic testing methods apply an instantaneous load. A test takes a mere 2 seconds and, using the standard probe D, leaves an indentation of just ~0.5 mm in diameter on steel or steel casting with a Leeb hardness of 600 HLD.
