Introduction

Background of Standard Revision and Technological Evolution

As the first revision of HJT 194-2005, HJ 194-2017 reflects the continuous improvement of my country's environmental monitoring technology system. The standard drafting units include five institutions including China National Environmental Monitoring Center. The main revisions include:

Revision dimensions	2005 edition	2017 edition
Scope of application	Basic requirements	Expanded pollutant types
Technical details	Simple framework	New chapters such as Data processing and Transportation and Storage
Number of appendices	3	Increased to 5 (new D/E appendix)

Analysis of core technical requirements

4.1 Principles for the layout of monitoring points

The standard clearly requires that sampling points must meet the following requirements:

Collection space above 270° on the horizontal plane
Distance twice the height difference of obstacles
Sampling port height range 1.5-15m

Case: A PM_2.5 monitoring point in a certain city had abnormal data due to its location in a blind spot of a building. After adjustment, the data was abnormal due to the 180° free space required by the standard, and the monitoring value returned to a reasonable range.

Implementation Suggestions

Connection between the old and new standards: The new standard will be fully implemented from April 1, 2018, and the sampling record form needs to be updated (refer to Appendix D)
Quality control focus: Calibrate the soap film flowmeter at least once a month (Appendix C)
Special weather treatment: Sampling should be suspended when the wind speed is greater than 8m/s or in dusty weather
