6 Test schedule
6.1 General
6.1.1 Introductory remarks
This test schedule shows the tests and the order in which they shall be carried out as well as
the requirements to be met.
Unless otherwise specified, all tests shall be carried out under standard atmospheric
conditions for testing as specified in IEC 60068-1, as directed by the applicable part of
IEC 60512.
Unless otherwise specified, mated and locked sets of connectors shall be tested. Care shall
be taken to keep a particular combination of connectors together during the complete test
sequence, i.e. when unmating is necessary for a certain test, the same connector styles as
before shall be mated for the subsequent tests.
In the following, a mated and locked set of connector styles is called a specimen.
When the initial tests have been completed, all the specimens are divided in the 4 test groups
AP,BP,CP and DP. In addition 20 single contacts are used for EP and 20 additional
specimens for FP.
Before testing commences, the connectors shall be stored for at least 24 h in the non-
engaged state under standard atmospheric conditions as per IEC 60068-1.
The necessary specimens are stated in Table 11.
