This standard is intended to provide general design criteria and guidance for handling equipment associated with weapons and other items of similar nature and should be used as the basis for preparing development specifications for such equipment. However, this standard should not be substituted for sound engineering judgement with respect to establishing specific requirements for handling equipment needed to solve unique handling situations. The need for sound engineering judgement is further emphasized in light of the elimination of many government reference documents (military specifications, military standards, etc.) from this standard in order to encourage greater use of commercial products wherever possible. The intent of this standard, therefore, is to provide sufficient information and latitude for the use of commercial products, and to define those unique requirements, such as shipboard and aircraft interface criteria, which are not likely to be found in the commercial section and require the use of the documents referenced.
