e) calculate, for each pollutant Dp = 6 (EIn) (Wfn) (t) where: t time in LTO mode (minutes) Wfn fuel mass flow rate (kg/min) is the summation for the set of modes comprising the reference LTO cycle. 7.2.4 While the methodology described above is the recommended method, the certificating authority may accept equivalent mathematical procedures which utilize mathematical expressions representing the curves illustrated if the expression have been derived using an accepted curve fitting technique. 7.3 Exceptions to the proposed procedures In those cases where the configuration of the engine or other extenuating conditions exist which would prohibit the use of this procedure, the certificating authority, after receiving satisfactory technical evidence of equivalent results obtained by an alternative procedure, may approve an alternative procedure. 24/11/05 No. 5 2007/70/II. szám ANNEX 16 — VOLUME II 20/3/97 No. 3 ATTACHMENT A TO APPENDIX 3. SPECIFICATION FOR HC ANALYSER Note 1.— As outlined in 5.2 of Appendix 3, the measuring element in this analyser is the flame ionization detector (FID) in which the whole or a representative portion of the sample flow is admitted into a hydrogen-fuelled flame. With suitably positioned electrodes an ionization current can be established which is a function of the mass rate of hydrocarbon entering the flame. It is this current which, referred to an appropriate zero, is amplified and ranged to provide the output response as a measure of the hydrocarbon concentration expressed as ppmC equivalent. Note 2.— See Attachment D for information on calibration and test gases. 1. GENERAL Precautions: The performance specifications indicated are generally for analyser full scale. Errors at part scale may be a significantly greater percentage of reading. The relevance and importance of such increases shall be considered when preparing to make measurements. If better performance is necessary, then appropriate precautions shall be taken. The instrument to be used shall be such as to maintain the temperature of the detector and sample-handling components at a set point temperature within the range 155°C to 165°C to a stability of ±2°C. The leading specification points shall be as follows, the detector response having been optimized and the instrument generally having stabilized:
