ABSTRACT:
A test head (10) for breathing mask testing includes a hard head part (12) formed of a hard material and includes a face side (18) and a soft face front (14) of a defined thickness applied to the face side (18) of the hard head part (12). The soft face front (14) has a simulated human face surface defining a mask seal contact surface (22). A breathing mask testing system is also provided including the testing head (10) including a human face surface defining a mask seal contact surface (18) and a mouth opening connected to a respiration tube (50). A testing device (32) is provided with a test head adapter (30) protruding from the testing device (32). The hard head part (12) has a support portion (29) with an adapter interface for the adapter (30). The adapter interface includes a rotational position fixing mechanism for fixing the hard head part (10) to the adapter (30) in one of a plurality of rotational positions.
