In the reporting of Fuels Quality, EEA Report No 24/2017 for example, section 3.4 Exceedances of fuel quality limits, talks about tolerance limits. How are the tolerance limits determined? I've looked at EN14724:2013, and it mentions &quot;Limiting Values&quot; -<br />The limiting values are &quot;true values&quot; according to EN ISO 4259, but I don't see Tolerance Limits mentioned. Are they +/-0.59R depending on a max or min limit, or some other factor of R?<br />&nbsp;Very much appreciate your guidance.<br />&nbsp;<br />
