1-7 HEW Field Tests
SM A 0654E
Field Tests for HEW Compliance are inciuded in the installation procedures of Chapter 4, Part 11. These
are an elaboration of the generalized procedures given in Direction 13894 “Field Tests for HEW Compliance.”
The table below lists all pertinent HEW Field Tests for the AMX-II.
Reference is given to the appropriate
test in Direction 13894, and the corresponding section in this Chapter. For a new installation, follow the
procedures given in the tables and record data on Form F3382 “System Field Tests for HEW Compliance“
and/or Form 3316 "PMS Data Record—Mobile Generator |.”
