Abstract
A test accessory for testing a variety respirators. The accessory is designed to compliment existing equipment to provide a robust assessment of respirator performance. The accessory may include a head form having an inflatable bladder capable of fitting a variety of sizes of respirator masks. In some embodiments, the inflatable bladder does not rely on adhesives to effect a seal, thereby eliminating manufacturing and quality assurance steps. The test accessory may also include a detachable instrumentation module that may be removed from the accessory, enabling calibration and maintenance at a remote facility without need for transporting the entire unit. The module may also house a memory device that may be upgraded with calibration data and firmware during the calibration process.
