NOTES:
All tests were conducted with the fuses soldered to a printed circuit boards with a nominal thickness of 1.6 mm. The copper test circuit trace
was a printed circuit with an overall length of 100 mm, copper thickness/width as described
below. The printed circuit boards were mounted by screws to a test fixture having brass
blocks for connection of the test leads. All samples were soldered to the test boards by the
manufacturer.
