perform a technical inspection at least annually,
consisting of, for example, inspection of the filter for
damage, air tightness of the machine and proper
function of the controlmechanism.
• In addition, on class H machines, the machine
filtration efficiency should be tested at least annually,
or more frequently as may be specified by national
requirements. The test method that can be used to
verify the machine’s filter efficiency is specified in
22.AA.201.2. If the test fails, it shall be repeated with
a newfilter.
