terminal. The reversed units shall also be marked with an R following the last digit in the type number.
3.7 Electrical performance characteristics. Unless otherwise specified herein, the electrical performance
characteristics are as specified in 1.3 and table I herein.
3.8 Electrical test requirements. The electrical test requirements shall be the subgroups specified in 4.4.2 and
4.4.3.
* 3.9 Workmanship. Semiconductor devices shall be processed in such a manner as to be uniform in quality and
shall be free from other defects that will affect life, serviceability, or appearance.
4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are classified as follows:
a.
Qualification inspection (see 4.2).
