Scope
Main technical content: This document specifies the calibration method for particulate matter concentration measuring instruments used for vehicle emissions. This document is applicable to the overall calibration of portable particulate number concentration measuring instruments based on the CPC method or the DC method (including heated sampling tubes, volatile particulate matter removers, and particulate counters) and the step-by-step calibration of bench-mounted particulate number concentration measuring instruments (including heated sampling tubes and volatile particulate matter removers, while calibrating the PCRF and VRE, and calibrating the particulate counter's flow rate and detection efficiency, etc.)
