There is a discrepancy between the requirements of the test cases 7.6.3.2.10, 7.6.3.2.11, 7.6.3.2.12, and table 30 in IEC 62351-5:2013.
According to the table 30 in IEC 62351-5:2013 the Reply timeout statistics has to be increased always when a Reply timeout happens. The test cases imply that it has to be increased only when “Reply Timeouts <= Max Reply Timeouts”
In 7.6.3.2.12 there is the requirement that the reply timeout statistics has to be reset. This is also in contrast to IEC 62351-5:2013 where it is specified that the "Max Reply Timeouts" has to be reset.
Proposal
“Increment Reply Timeouts statistics” should be moved from 7.6.3.2.11 to 7.6.3.2.10
Then 7.6.3.2.11 can be removed because it would be empty.
In 7.6.3.2.12: “Reset Reply timeouts statistics” should be replaced by “Reset Max Reply Timeouts” to be in line with IEC 62351-5:2013 table 30.

I agree that the first two proposed changes wouldn't change the behaviour.
Only the third proposed change is required: change the text "Reset Reply timeouts statistics" to "Reset Max Reply Timeouts" in test case 7.6.3.2.12.
Similar issues are also in other test cases. E.g. in 7.6.3.2.18 "Reset Reply Timeout statistic" should also be replaced by "Reset Max Reply Timeouts" or in 7.6.3.2.6 where "Reset the Authentication Failures statistic" should be replaced by "Reset Max Authentication Failures".

The proposed change in the first two statements does not modify the behaviour of the DUT since, as stated in the test case 7.6.3.2.11 the Reply Timeout Statistic is incremented only if it's value is lower or equal (<=) to the Max Reply Timeouts. This ensure that the Reply Timeout Statistic is able to be greather than the Max Replay Timeouts.
If the Reply Timeout Statistic is strictly greather than Max Reply Timeouts then the operation indicated in test case 7.6.3.2.12 shall be executed.
In test case 7.6.3.2.11 the first statement "If Reply Timeouts <= Max Reply Timeouts:" shall be changed to "If Reply Timeout Statistic <= Max Reply Timeouts:".
Agreed to change the text "Reset Reply timeouts statistics" to "Reset Max Reply Timeouts" in test case 7.6.3.2.12.
