In order to implement Environmental Protection Law of the PEOPLE Republic of China, Water Pollution Prevention and Control Law of the PEOPLE Republic of China and Atmospheric Pollution Prevention Law of the PEOPLE Republic of China, standardize the monitoring of pollution source, and ensure the accuracy and reliability of monitoring data and information, hereby formulate this Standard.
This Standard specifies technical requirements for quality assurance and quality control of sampling and testing in the process of manually monitoring and comparison monitoring of waste water discharge and exhaust emission of stationary pollution source. This Standard is a directive standard.
This Standard is proposed by the Department of Science, Technology and Standards of State Environmental Protection Administration.
Drafting organizations of this Standard are. China National Environmental Monitoring Center, and Shenyang Municipal Environmental Monitoring Center.
This Standard was approved by State Environmental Protection Administration on November 12, 2007.
This Standard was implemented on January 1, 2008.
State Environmental Protection Administration shall be responsible for interpreting this Standard.

3 Terms and definitions
For the purpose of this Standard, the following terms and definitions shall apply. 3.1 Quality assurance
The total quality management during the process of environment monitoring includes all activities and measures to ensure the accuracy and reliability of environmental monitoring data.
3.2 Quality control
It refers to the operational techniques and activities adopted to meet the quality requirements of environmental monitoring.
3.3 Comparison monitoring
It refers that in order to verify the accuracy of results of water and gas online automatic monitor, manual monitoring method and online automatic monitor method are simultaneously adopted; manual monitoring results are the basis for verifying online automatic monitoring data. Of which the manual monitoring methods shall use national standard methods or other currently effective methods.
3.4 Field-laboratory quality control
It refers to the process of synchronous sampling and analysis of quality control samples and practical samples according to fixed routines. And its quality control results can be used to determine whether the error of the monitoring results derives from field sampling or laboratory analysis.
