However the newer OSHA Fast Fit Protocols for CNC methods, and introduction of newer instruments, have made all quantitative fit test devices equivalent in price and time required for testing. The CNP method has at present about 15% of the fit test market in industry. [25] The Current CNC instruments are the PortaCount 8040 and the AccuFIT 9000.
Generates signals for testing purposes Spectrum analyser: Displays frequency spectrum Sweep generator: Creates constant-amplitude variable frequency sine waves to test frequency response Transistor tester: Tests transistors Tube tester: Tests vacuum tubes (triode, tetrode etc.) Wattmeter: Measures power in a circuit Vectorscope
A trend towards recommending HPD fit-testing as a best practice is emerging in the European Union and the USA. [18] [19] On January 2025 NIOSH published a Science Policy Update recommending employers use individual, quantitative fit testing to evaluate the attenuation received by workers from their hearing protection devices.
