shorted load test twice can be eliminated if the manufacturer has demonstrated process control under the
SPC program (see 3.3.1), or other method that has been approved by the qualifying activity. If the design,
material, technology, or processing of the part is changed or, if there are any quality problems or failures,
the qualifying activity may require resumption of the specified testing. Deletion of testing does not relieve
the manufacturer from meeting the test requirement in case of dispute.

e.
Verify the SSR shuts OFF by measuring the output current I(output).
Reset SSR, then repeat twice the steps outlined in 4.7.7.6a through 4.7.7.6e. Repeating this shorted load
f.
test twice can be eliminated if the manufacturer has demonstrated process control under the SPC program
(see 3.3.1), or other method that has been approved by the qualifying activity. If the design, material,
technology, or processing of the part is changed or, if there are any quality problems or failures, the
qualifying activity may require resumption of the specified testing. Deletion of testing does not relieve the
manufacturer from meeting the test requirement in case of dispute.
