scope:

This standard establishes the requirements for providing test points in prime equipments for monitoring by on-line automatic test equipment (ATE). It provides criteria for guidance in optimum test point selection. It defines interface and data requirements, a system of test point data generation, and procedures for submission of data disclosing the selections of these test pints.

The requirements of this standard are applicable to the design of equipments intended to be interfaced with an ATE. This standard may also be used for the retrofit of existing equipments for ATE monitoring.

It is the intent of this standard to specify the requirements of the procuring activity to achieve the following objectives:

(a) The optimum selection and placement of test points to:

(1) Continuously monitor the performance of prime equipment.

(2) Indicate the existence of a failure.

(3) Facilitate rapid isolation of a failure to the line replaceable unit to effect repair by substitution of a spare, performance of realignment, etc.

(b) The planning and development of an adequate level of test logic design for the prime equipment in order that the ATE can be programmed to provide optimum monitoring of the sensor outputs, and to insure timely delivery of the end article and all of the required test point information.

(c) The definition of the types of test point signals and their dimensions that may be provided for ATE monitoring.
