Proposed ASTM International Standard Helps Evaluate Air Quality Sensors
ASTM International’s air quality committee (D22) is developing a standard that will help test and set assessment criteria for the performance of air quality sensors installed around cities, communities, and industrial sites.
Specifically, the proposed standard (WK64899) will outline laboratory and field tests that provide information on instrument repeatability, sensitivity, linearity, cross-interferences, temperature impacts, drift and measurement uncertainty, and more.
“People everywhere have a greater awareness of the impact of air quality on their health,” says Dr. Geoff Henshaw, CTO and founder of Aeroqual, and ASTM International member. “They want to know about the quality of the air where they live and work and they want that information in real-time. This test method will provide independent evidence for the performance of these devices and reliability of the air quality data they generate.”
Air quality agencies, first responders, “smart city” project leaders, environmental consultants, industrial site operations, and community groups would find this standard most useful, he says.
ASTM welcomes participation in the development of its standards. Become a member at www.astm.org/JOIN. The next meeting of the committee will be Oct. 21-24 in Washington, D.C. (USA).
