    WK43061

    1. Rationale

    Changes need to be made to correct the method issued last year, 2012. In paragraph 10.2.2 the decimal point was missing in the allowance for the pressure variation. The method was issued stating 7 kPa, whereas it should have been 0.7 kPa. In addition in paragraph 10.2.1 there is a reference to .the procedure specified in Section 12 and this is incorrect. It should state .. the procedure specified in Section 11 and the calculation specified in Section 12 . In addition there is a lack of clarity on the need in the manual method to make three individual determinations of the flame height with each measurement recorded to the nearest 0.5 mm and then averaged to give a single result. After the average value has been determined it is round to the nearest 0.1 mm then that value is used in the Calculation in Section 12 using the correction factor for the instrument determined by calibration against standard reference materials. The result from the Calculation in Section 12 is then rounded to the nearest 0.5 mm in the manual method. However, in the automatic method the flame height is measured automatically to the nearest 0.01 mm and the instrument takes three individual readings and calculates the average to the nearest 0.1 mm. It is this average reading by the automatic instrument that is then used in the equation 2 of the Calculation in Section 12 and reported to the nearest 0.1mm. There are 5 items of change in this ballot described individually below.
