1/
Dimensions taken shall be variables data. Dimensional verification may be waived with approval from the
qualifying activity if the contractor can demonstrate that these tests have been performed for three consecutive
periods with zero failures.
2/
High-low temperature operation, endurance and dimensions shall be performed the 4th quarter of the first
year, moisture resistance and dimensions shall be performed the 4th quarter of the second year, and
temperature rise, interrupting capacity and dimensions shall be performed the 4th quarter of the 3rd year.
After the third year, the sequence repeats.
3/
If the contractor can demonstrate that these tests have been performed for three consecutive periods with zero
failures, the frequency of these tests may be reduced after approval by the qualifying activity.
(i.e.; each quarterly test would become an annual test taking 6 years to complete a total cycle). If the design,
material, construction, or processing of the circuit breakers change, or if there are any quality problems or
failures, the qualifying activity may require resumption of the original test frequency.
