# Commission Delegated Regulation (EU) 2017/654 of 19 December 2016 supplementing Regulation (EU) 2016/1628 of the European Parliament and of the Council with regard to technical and general requirements relating to emission limits and type-approval for internal combustion engines for non-road mobile machinery, Division 3.1: Type: LPG

Extent: E+W+S+N.I.

Notes:
Balance shall be read as follows: balance = 100 – C3 – < C3 – > C4.
This method may not accurately determine the presence of corrosive materials if the sample contains corrosion inhibitors or other chemicals which diminish the corrosivity of the sample to the copper strip. Therefore, the addition of such compounds for the sole purpose of biasing the test method is prohibited.
At the request of the engine manufacturer, a higher MON could be used to perform the type approval tests.
