As per NFPA 20, it stataes that
"22.214.171.124 Field Retest Results.
126.96.36.199.1 The field retest results shall be compared to the original pump performance as indicated by the fire pump
manufacturer’s original factory-certified test curve, whenever it is available.
188.8.131.52.2 The field retest results shall meet or exceed the performance characteristics as indicated on the pump nameplate, and the results shall be within the accuracy limits of field testing as stated elsewhere in this standard."
My query is regarding the bold line that is mentioning "elsewhere in this standard" but I could find the anywhere in NFPA 20 "the accuracy limits".
Please help me by mentioning the reference where it provides the accuracy limit.
