b) the relative hydrocarbon response (whereby there is a different response to the same sample hydrocarbon concentrations expressed as equivalent ppmC, dependent on the class or admixture of classes of hydrocarbon compounds). The magnitude of the effects noted above shall be determined as follows and limited accordingly. Oxygen response: measure the response with two blends of propane, at approximately 500 ppmC concentration known to a relative accuracy of ±1 per cent, as follows: 1) propane in 10 ± 1 per cent O2, balance N2 2) propane in 21 ± 1 per cent O2, balance N2 If R1 and R2 are the respective normalized responses then (R1 – R2) shall be less than 3 per cent of R1. Differential hydrocarbon response: measure the response with four blends of different hydrocarbons in air, at concentrations of approximately 500 ppmC, known to a relative accuracy of ±1 per cent, as follows:
