AS/NZS1716:2003 is the Standard that dust masks must comply with in Australia and New Zealand. Each device must be tested to show that it provides effective respiratory protection against certain hazards. The respiratory device should be issued as part of a full respiratory protection program that covers: Hazard Control, Selection of PPE, Fit Testing, Maintenance and Storage Procedures.
Resistance to Flame Testing
This is where the respirator is assessed for its resistance to heat, for use in hot work environments.
Inward Leakage of Assembled Respirators
Quantitative sodium chloride test – A panel of people assess the performance of the respirator against sodium chloride (a gas which has much smaller particles than those found in the workplace). The test is for fit and does not indicate the performance of the respirator.
Breathing Simulator Test
This is where the respirator is tested on a breathing machine which simulates natural breathing in one of a number of environmental and test conditions such as carbon monoxide, temperature rises, carbon dioxide accumulation, resistance to breathing, positive pressure and exhaled air humidity.
Exhalation Valve Leakage Test
This is where the respirator is checked for potential leakages with a leakage meter apparatus.
Breathing Resistance Test
Breathing resistance is measured under continuous flow conditions at specified flow rates at a temperature of 23 +/- 3oC.
Simulated Rough Usage Test
This tests the respirators under conditions for rough usage and handling such as vibration and impact from falls.
Particulate Filters – Test for Filtering Efficiency
A test for initial filter penetration using an aerosol of sodium chloride.
Simulated Works Test
This test is designed to assess the suitability of self rescue and supply-air respirators for a variety of work situations.
Cylinder Valve Requirements
Valves are assessed for construction, materials, pressure rating, valve stem thread, valve outlet connection and manufacturer markings.
