17.6 Does each real-time text communication web application that can interact with other real-time text communication applications comply with the interoperability rules in force?

Test 1 (17.6.1)

This criterion is very complex to assess and requires a certain mastery of all interoperability concepts and standards.

We recommend asking the application publisher to check that all the requirements described in criterion 6.2.3 Interoperability of European standard EN 301 549 are met.
