7.8.9.2 Precision Check
A periodic check is used to assess the data for precision. A one-point precision check must be
carried out at least once every 2 weeks on each analyzer at an SO
2
concentration between 0.08 and
0.10 ppm. The analyzer must be operated in its normal sampling mode, and the precision test gas
must pass through all filters, scrubbers, conditioners, and other components used during normal
ambient sampling. The standards from which precision check test concentrations are obtained must
be traceable to NIST-SRM. Those standards used for calibration or auditing may be used.
7.8.9.3 Precision Check Procedure
1. Connect the analyzer to a precision gas that has an SO
2
concentration between 0.08 and 0.10
ppm. An SO
2
precision gas may be generated by either the SO
2
gas cylinder or a SO
2
permeation tube. If a precision check is made in conjunction with a zero/span check, it must
be made prior to any zero or span adjustments.
2. Allow the analyzer to sample the precision gas until a stable trace is obtained.
3. Record this value. Information from the check procedure is used to assess the precision of the
monitoring data; see 40 CFR 58 for procedures for calculating and reporting precision.
7.8.10 Recommended Standards for Establishing Traceability
To assure data of desired quality, two considerations are essential: (1) the measurement process
must be in statistical control at the time of the measurement and (2) the systematic errors, when
combined with the random variation in the measurement process, must result in a suitably small
uncertainty.
Evidence of good quality data includes documentation of the quality control checks and the
independent audits of the measurement process by recording data on specific forms or on a
quality control chart and by using materials, instruments, and measurement procedures that can
be traced to appropriate standards of reference. To establish traceability, data must be obtained
routinely by repeat measurements of standard reference samples (primary, secondary, and/or
working standards). More specifically, working calibration standards must be traceable to
standards of higher accuracy, such as those listed below in Table 7-15.
