Channel to chassis isolation test

To qualify the isolation as 1000 V RMS and 600 V CAT II (REINFORCED),
certain tests are performed on some cards during the engineering design
qualification phase. These tests are known as type tests. These tests are
described in the IEC61010-1:2010 and IEC61010-2-30:2010 standards. The
principle of the tests is given below.
For the isolation barrier test, both the DC and AC tests below (see Figure 3.1
and Figure 3.2) are used with DC voltage √2 higher than the AC voltage. The
test value meets the requirements for 600 V CAT II REINFORCED, the test
value for 1000 V RMS is lower and therefore also covered with this test. Tests
are conducted for one minute, see IEC61010 for details.
