  "text": "1.\nThis Appendix describes the procedure to be used to verify the production conformity requirements for the Type 1 test for pollutants/CO 2 , including conformity requirements for PEVs and OVC-HEVs, and to monitor the OBFCM device accuracy.\n2.\nMeasurements of the pollutants specified in Table 2 of Annex I to Regulation (EC) No 715/2007, and the emission of CO 2 shall be carried out on a minimum number of 3 vehicles, and consecutively increase until a pass or fail decision is reached. The OBFCM device accuracy shall be determined for each of the N tests.\nFrom the number of N tests: x1, x2, … xN, the average Xtests and the variance VAR are to be determined from all N measurements:\nXtests=x1+ x2+ x3+ …+ xN∕N\nand\nVAR=x1− Xtests2+x2− Xtests2+ …+xN− Xtests2∕N− 1\n3.\nFor each number of tests, one of the three following decisions (see (i) to ((iii) below) can be reached for pollutants based on the limit value L for each pollutant, the average of all N tests: Xtests, the variance of the test results VAR and the number of tests N:\n(i)Pass the family if Xtests<A× L− VAR∕L\n(ii)Fail the family if Xtests>A× L−N− 3∕13× VAR∕L\n(iii)Take another measurement if:\nA × L − VAR∕L≤Xtests≤A × L −N − 3∕13× VAR ∕ L\nFor the measurement of pollutants the factor A is set at 1,05 in order to take into account inaccuracies in the measurements.\n4.\nFor CO2 and EC the normalised values for CO2 and EC shall be used:\nxi=CO2test− i∕CO2declared.\nxi=ECtest− i∕ECDC, COP\nIn the case of CO2 and EC the factor A is set at 1.01 and the value for L is set at 1. So in the case of CO2 and EC the criteria are simplified to:\n(i)Pass the family if Xtests<A− VAR\n(ii)Fail the family if Xtests>A−N− 3∕13× VAR\n(iii)Take another measurement if:\nA − VAR≤Xtests≤A −N − 3∕13× VAR\n. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .\n5.\nFor vehicles referred to in Article 4a, the accuracy of the OBFCM device shall be calculated as follows:\nx i,OBFCM accuracy of the OBFCM device determined for each single test i in accordance with the formulae point 4.2 of Annex XXII.\nThe Type Approval authority shall keep a record of the determined accuracies for each COP family tested.",
