10.1.3.RECOMMENDED STANDARDS FOR ESTABLISHING TRACEABILITY

To assure data of desired quality, two considerations are essential:

∙The measurement process must be in statistical control at the time of the measurement.

∙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 in Table 3-7.

Cylinders of working gas traceable to NIST-SRMs (called EPA Protocol Calibration Gas) are also commercially available (from sources such as Scott Specialty Gases, etc.). See Table 3-7for a list of appropriate SRMs.
