Life -------------------------------------------------
1/ Select the specified number of relays at random from the 11 sample units.
2/ A test procedure (e.g., dielectric withstanding voltage) required at the conclusion of a procedure shall be
known as a post-test of that procedure. Some post-tests are required to be repeated on sample units as
post-tests for more than one test procedure. At the option of the manufacturer, such post-testing shall be
required only at the conclusion of the life test.
3/ One additional sample unit is included in each sample of 11 sample units to permit substitution for the
failures allowed in group I.
