I don't think so. Even if the AC says so! It "should be tested" for sure.
But don't count on it! Sometimes they don't even clean it out after

Can't speak for all shops.  I know for a fact that some of the higher
production shops did sample testing.  I am not sure if the FAA requires 100%
testing.

I will definatly Test and clean my own hoses.  A test rig would simple to
put together.

Cheap peice of mind.

Don't forget firesleeve on all hoses in the engine compartment.
