# Commission Regulation (EU) 2017/1151 of 1 June 2017 supplementing Regulation (EC) No 715/2007 of the European Parliament and of the Council on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information, amending Directive 2007/46/EC of the European Parliament and of the Council, Commission Regulation (EC) No 692/2008 and Commission Regulation (EU) No 1230/2012 and repealing Commission Regulation (EC) No 692/2008 (Text with EEA relevance), Division 3.4: Calculation of available power


The available power for each possible gear i and each vehicle speed value of the cycle trace vi shall be calculated using the following equation:
Pavailable_i,j = Pwot (ni,j) × (1 – (SM + ASM))
where:
Pratedis the rated power, kW;
Pwotis the power available at ni,j at full load condition from the full load power curve;
SMis a safety margin accounting for the difference between the stationary full load condition power curve and the power available during transition conditions. SM is set to 10 per cent;
ASMis an additional power safety margin which may be applied at the request of the manufacturer.
When requested, the manufacturer shall provide the ASM values (in per cent reduction of the wot power) together with data sets for Pwot(n) as shown by the example in Table A2/1. Linear interpolation shall be used between consecutive data points. ASM is limited to 50 per cent.
The application of an ASM requires the approval of the approval authority.
