Invited by the Henan Provincial Institute of Metrology to Participate in the Formulation of Local Standards

According to JJF 1071-2010 “Rules for Compilation of National Metrological Calibration Specifications”, JJF 1059.1-2012 “Assessment and Expression of Measurement Uncertainty”, HJ 93-2013 “Technical Requirements and Testing Methods for Environmental Air Particulate Matter (PM10 and PM2.5) Samplers”, WS/T 206-2001 “Determination of Inhalable Particles (PM10) in Ambient Air in Public Places – Light Scattering Method”, and combined with the current production, use, and calibration status of particulate matter sensors in our province, we formulated relevant standards accordingly.

In 2016, our technical director Yang Yongshen and our technical team were invited by the Henan Provincial Institute of Metrology to participate in the formulation of local standards and calibration specifications for Henan Province.
