10.2.2 The arithmetic mean in newto

10.2.2 The arithmetic mean in newtons for the test specimen is calculated using all peaks recorded according to 10.2.1.10.2.3 From the mean calculated for each test specimen (see 10.2.2) calculate the overall arithmetic mean of the tear force in newtons for each direction tested and round it to two significant figures.10.2.4 If required, calculate the coefficient of variation to the nearest 0,1%and the 95% confidence limits in newtons rounded to two significant figures, using the specimen mean values as calculated according to 1 0.2.2.11Test reportThe test report shall include the following information:11.1 General informationa) Reference to this part of EN ISO 13937 and the date of test;b) identification of test sample and if required, sampling procedure;c) number of test specimens and number of tests rejected and reasons for this;d) observations on unusual tear behaviour;e) whether mean values are calculated manually (see 10.1)or by electronic device (see 10.2).f) any deviation from the given procedure, specifically if a wide-width test specimen was used (see 8.2.2)11.2 Test resultsa) The overall mean tear force across-warp and across-weft, in newtons. If only 3 or 4 test specimens are torn correctly, state the results for the individual test specimens only;b) if required, the coefficient of variation, in percent;c) if required, the 95% confidence limits, in newtons;d) if required, in case of manual evaluation (see 10.1)，the mean of the highest peak force values for each test specimen (see 10.1.5), in newtons;e) if required, in case of manual evaluation (see 10.1)，the lowest and highest peak force value recorded for each test specimen (see 10.1.6), in newtons.
