SIR #: 336
Section: V1M4, Section 220.127.116.11
Section 18.104.22.168 of V1M4 states that the laboratory must determine the acceptance limits for precision and recovery prior to analysis if 4 routine laboratory control samples are used for continuing DOC. Does this allow for the use of marginal exceedance criteria?
TNI FINAL RESPONSE:
The use of marginal exceedance limits are allowed for ODOC as long as the upper and lower marginal exceedance limits have been established for LCS acceptance criteria per V1M4 22.214.171.124 b before the analysis of any of the four LCSs. Note that the use of marginal exceedance may be disallowed by method, regulation or project due to more stringent requirements as specified in V1M2 1.2.
