Foreword
In order to implement Environmental Protection Law of the People’s Republic of China,
Water Pollution Prevention and Control Law of the People’s Republic of China and
Atmospheric Pollution Prevention Law of the People’s 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.
Technical specifications of quality assurance
and qualify control for monitoring of stationary
pollution source (on trial)
1 Scope of application
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 applies to the environmental monitoring of waste water discharge and
exhaust emission of stationary pollution sources.

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.
4 The technical requirements of quality assurance and quality control for waste
water monitoring
4.1 Monitoring personnel
When water is deeper than 1 m, sampling shall be conducted at 1/4 depth of water under
surface layer; when depth of water is not more than 1 m, sampling shall be conducted at
1/2 depth of water; the sampling location shall be close to the center of sampling section
and comply with the requirements of 6.3.2 in HJ/T92-2002.
