 (1)  NT shall be rounded to the next higher integer number
        (2)  When there is only one vehicle emission type in a PEMS test family, the type approval authority shall decide whether the vehicle shall be tested in hot or cold start.

              6.5. Reporting for type approval

              6.5.1. The vehicle manufacturer shall provide a full description of the PEMS test family, which shall include the technical criteria described in paragraph 6.3.1.2. and submit it to the authority.

              6.5.2. The manufacturer attributes a unique identification number of the format PF-CP-nnnnnnnnn…-WMI to the PEMS test family and communicates it to the authority:

                     where:

                         PF denotes that this is a PEMS test Family

                         CP is the Contracting Party issuing the type approval according to this Regulation[2]

                         nnnnnnnnn… is a string with a maximum of twenty five characters, restricted to using the characters 0-9, A-Z and the underscore character '_'.

                         WMI (world manufacturer identifier) is a code that identifies the manufacturer in a unique manner defined in ISO 3780:2009.

              It is the responsibility of the owner of the WMI to ensure that the combination of the string nnnnnnnnn… and the WMI is unique to the family and that the string nnnnnnnnn… is unique within that WMI to the approval tests performed to obtain the approval.

              6.5.3. The granting approval authority and the vehicle manufacturer shall maintain a list of vehicle emission types being part of a given PEMS test family on the basis of emission type approval numbers.

              6.5.4. The granting approval authority and the vehicle manufacturer shall maintain a list of vehicle emission types selected for PEMS testing in order to validate a PEMS test family in accordance with paragraph 6.4., which also provides the necessary information on how the selection criteria of paragraph 6.4.3 are covered. This list shall also indicate whether the provisions of paragraph 6.4.1.3. were applied for a particular PEMS test.

              6.6. Rounding requirements:

Rounding of data in the data exchange file, as defined in paragraph 10. of Annex 7, is not permitted. In the pre-processing file, the data may be rounded to the same order of magnitude of the accuracy of the measurement of a respective parameter.
              The intermediate and final emission test results, as calculated in Annex 11, shall be rounded in one step to the number of places to the right of the decimal point indicated by the applicable emission standard plus one additional significant figure. Preceding steps in the calculations shall not be
