SFR16S/25/25H

TESTS AND REQUIREMENTS

Essentially all tests are carried out in accordance with

IEC 60115-1 specification, category LCT/UCT/56 (rated

temperature range: Lower Category Temperature, Upper

Category temperature; damp heat, steady state, test

duration: 56 days).

The tests are carried out in accordance with IEC 60068-2-xx

test

method

under

standard

atmospheric

conditions

according to IEC 60068-1, 5.3.

In the Test Procedures and Requirements table, tests and

requirements are listed with reference to the relevant clauses

of IEC 60115-1 and IEC 60068-2-xx test methods. A short

description of the test procedure is also given. In some in-

stances deviations from the IEC recommendations were

necessary for our method of specifying. All soldering tests

are performed with mildly activated flux.
