IEEE Std 716-1995, IEEE Standard Test Language for All Systems—Common/Abbreviated Test Language for All Systems (C/ATLAS)

ATLAS, an acronym for Abbreviated Test Language for All Systems, is the major test language that has been used for many military and commercial avionics test requirements for more than 30 years. It is still used on most of the large military and avionics test systems in use today.


The major benefits of using ATLAS are:

• it provides a readable test specification language
• it describes tests with respect to the Unit Under Test
• it is independent of any particular test system or equipment
• it is non-proprietary
• it is independently developed by consensus under the IEEE's rules.

Many thousands of Test Requirements have been written and many thousands of Test Program Sets have been developed using ATLAS. This legacy means that a large number of these programs will be maintained for many years into the future. ATLAS has stood the test of time and remains an essential tool for the long-term maintenance of military equipment and commercial avionics. ATLAS programs often outlive the original test equipment and the portability of these programs eases the task of moving to replacement test systems.

This standard is available from the IEEE and may be purchased online via their Products Website. A Guide providing information on the use of ATLAS is also available.

Although no major development of the language has occurred since 1995, its continued use by many organizations led to the reaffirmation of the standard in 2000 and 2006. It will be due for reconsideration again in 2011.

There are several designs of test system in current use that use earlier subsets of ATLAS. These earlier versions are also available from the IEEE via the IEEE Xplore website:

IEEE Std 716-1989, IEEE Standard C/ATLAS Test Language.

IEEE Std 716-1985, IEEE Standard C/ATLAS Test Language.
