7.8.12.1 NO Working Standard Traced to NIST NO Standard
First, use the NIST-traceable NO standard and the GPT calibration procedure to calibrate the
NO, NO , and NO
x
Refer to the calibration procedure described in Section 7.8.4.2.
Then, generate several NO concentrations by diluting the NO working standard. Use the nominal
NO cylinder concentration, [NO]
NO response (in ppm) versus the nominal diluted NO concentration and determine the slope,
S . Calculate the NO concentration of the working standard [NO]
NOM
[NO] = [NO]

A procedure is presented in the TAD in Reference 2.
7.8.12.2 Other Methods of Establishing Traceability
They are:
1. NO working standard traced to NIST NO2 standard
2. NO working standard traced to NIST NO2 standard

For further information on calibration by GPT and NO
devices, refer to part 50 of Chapter 1, Title 40 CFR, Appendix F
(revised December 1, 1976) and Reference 13 of that Appendix.
