sum of measured CO, HCHO and HCOOH shall not exceed 0.2 µmol/mol
(d)  As a minimum, total sulphur compounds include H2S, COS, CS2 and mercaptans, which are typically found in natural gas.
(e)  Test method shall be documented. Test methods defined in ISO 21087 are preferable.
(f)  The analysis of specific contaminants depending on the production process shall be exempted. A vehicle manufacturer shall provide the responsible authority reasons for exempting specific contaminants.

     Annex B4

     Road load and dynamometer setting
              1. Scope
              This annex describes the determination of the road load of a test vehicle and the transfer of that road load to a chassis dynamometer.
              2. Terms and definitions
              2.1. For the purpose of this document, the terms and definitions given in paragraph 3. of this Regulation shall have primacy. Where definitions are not provided in paragraph 3. of this Regulation, definitions given in ISO 3833:1977 "Road vehicles -- Types -- Terms and definitions" shall apply.
              2.2. Reference speed points shall start at 20 km/h in incremental steps of 10 km/h and with the highest reference speed according to the following provisions:
                  (a) The highest reference speed point shall be 130 km/h or the reference speed point immediately above the maximum speed of the applicable test cycle if
