Hi Kevin! You didn't specify the measurement method, but if you use thermocouples, does your lab use use OD5012 (used to be called OP-108 and 109)? It is also from the IECEE but gives guidance on how to prepare and use thermocouples. You asked for guidance on acceptable tolerances, which this doesn't really provide, but maybe applying these OPs to your lab can help solve the problem. -Ken A
