1/ Marking defects shall be charged only for illegible, incorrect, or incomplete marking.
Any subsequent electrical defect shall not be charged as a marking defect.
2/ The manufacturer may request the deletion of the subgroup 3 solderability test,
provided an in-line or process control system for assessing and assuring the
solderability of leads can be validated and approved by the qualifying activity.
Deletion of the test does not relieve the manufacturer from meeting this requirement
in case of dispute. If the design, material, construction, or processing of the part is
changed or if there are any quality problems, the qualifying activity may require
resumption of the test.
4.6.2.1.1.1 Manufacturer's production inspection. If the manufacturer performs tests similar to those
specified in subgroup 1 of table VI as the final step of the production process, group A, subgroup 1
inspection may be waived and results from the manufacturer's production tests may be used instead.
Authority to waive the subgroup 1 inspection shall be granted by the qualifying activity only. The following
criteria must be complied with:
a. Tests conducted by the manufacturer during production shall be clearly identical to or more
stringent than those specified for subgroup 1. Test conditions shall be equal to or more stringent
than those specified for subgroup 1 tests.
b. Manufacturer subjects 100 percent of the product supplied under this specification to the
production tests.
c. The parameters measured and the failure criteria shall be the same or more stringent than those
specified herein.
d. The lot rejection criteria are the same or more stringent than those specified herein.
e. Once approved, the manufacturer shall not change the test procedures or criteria without prior
notification to and concurrence from the qualifying activity.
