Cleaning process for a test device, computer program product for performing such a process, and test device

A cleaning apparatus (3) for a test apparatus (1), comprising:

• at least one fluid connection (57a) for a container (61a) for a cleaning fluid (63), wherein the fluid connection (57a) is fluidically coupled with a complementary connection (75) via a fluid supply line (73, 73a), wherein the complementary connection (75) can be fluidically coupled with an external connection (23, 25, 27, 29) of the test apparatus (1), and
• at least one fluid connection (57b) for a container (61b) for a flushing fluid (65), wherein the fluid connection (57b) is fluidically connected with the complementary connection (75) via a fluid supply line (73, 73b);
• at least one apparatus for delivering a cleaning fluid (63) and/or a flushing fluid (65) from one of the containers (61a, 61b) to the complementary connection (75);
• at least one connection (87a, 87b, 87c) for a collecting apparatus (89) for collecting the cleaning fluid (63) and/or flushing fluid (65) exiting the test apparatus (1), wherein the collecting apparatus (89) can be coupled with at least one external connection (23, 25, 27, 29) of the test apparatus (1) by means of at least one fluid discharge line (95a, 95b, 95c, 95d);
• an apparatus for providing a vaporous or gaseous cleaning fluid (63), that can be coupled with an external connection (23, 25, 27, 29) of the test apparatus (1) by means of a cleaning fluid supply line (73);
• a separating apparatus, being coupled to the cleaning apparatus (3);
• and
• at least one connection (87a, 87b, 87c) for the separating apparatus for separating the cleaning fluid (63) exiting the test apparatus (1) into a liquid phase and a gaseous phase,
• wherein the separating apparatus can be coupled with at least one external connection (23, 25, 27, 29) of the test apparatus (1) by means of a fluid discharge line (95a, 95b, 95c, 95d), and
• wherein the liquid phase arising in the separating apparatus is collectable in a collecting container (89), and the gaseous phase arising in the separating apparatus escapes into the environment.
