Non-Road Mobile Machinery (NRMM)

This page was last updated on 20th February 2020

Regulation (EU) 2016/1628 of the European Parliament and of the Council of 14 September 2016 sets out the requirements relating to gaseous and particulate pollutant emission limits and type-approval for internal combustion engines for non-road mobile machinery, also amends Regulations (EU) No 1024/2012 and (EU) No 167/2013.

The Regulation requires that, in order to be first placed on the EU market, engines for use in non-road mobile machinery must be approved to demonstrate compliance with pollutant emission limits.  The Regulations apply to new engines to be installed in non-road mobile machinery, intended and suited to move, or to be moved on the ground, either on or off the road.

What counts as non-road mobile machinery?

‘Non-road mobile machinery’ means any mobile machine, transportable equipment or  vehicle with or  without bodywork or wheels which:

  • Is not intended for carrying passengers or goods on the road;
  • includes machinery installed on the chassis of vehicles intended for the transport of passengers or goods on roads;
  • installed with a combustion engine – either an internal spark ignition (SI) (“petrol”) engine, or a compression ignition (CI) (“diesel”) engine

Examples of non-road mobile machinery include, but are not limited to:

  • garden equipment, such as hedge trimmers and hand-held chainsaws
  • generators
  • bulldozers
  • pumps
  • construction machinery
  • industrial trucks
  • fork lift trucks
  • mobile cranes

Exclusions

The NRMM regulations do not apply to:

  • aircraft
  • certain specialist applications – military and recreational craft, road vehicles and ships for intended use at sea

If a replacement engine is fitted to NRMM, it must meet the emissions requirements that were in place on the date when the machinery first came into service.

Approval requirements engines for non-road mobile machinery

Engines for use in NRMM that will be sold in EU Member States need to have  type-approval to Stage V (unless they are covered by the provisions for Transition Engines). This applies whether the engines are already installed in NRMM or not.

Vehicle Certification Agency is the approval authority in the UK. However, you can apply for type approval to any authorised body in an EU member state. The information below assumes that you are applying to the VCA for type approval.

If your engine meets the relevant requirements, the VCA will issue a type approval certificate for all engines in the same series – i.e. those that conform to the data in the technical file. Any subsequent amendments or alterations to the engine must be approved by the VCA. This might involve further tests.

Engine marking requirements

Approved engines must bear the following markings:

  • trade mark or trade name of the engine manufacturer
  • the engine type, engine family (if applicable) and a unique ID number
  • the EC type approval number

The mark must be:

  • durable for the useful life of the engine
  • secured to an engine part necessary for normal engine operation and not normally requiring replacement during engine life

The engine must be supplied with a supplementary movable plate that can be positioned, if necessary, to make the marks visible when the engine is installed in a machine.

The engine must bear all the relevant markings before it leaves the production line.

Placing NRMM on the market

If you intend to place NRMM in a European Union (EU) member state or in the UK, the equipment must only use engines that have been type approved. The responsibility for obtaining type approval rests with the engine manufacturer, and not the manufacturer of the NRMM itself or the retailer. However, when an engine is manufactured outside the EU, the manufacturer of the NRMM needs to ensure that it has an appropriate type approval certificate from an accredited body in an EU member state. This can be done either by direct arrangement with the approval authority, or in collaboration with the engine manufacturer’s local representative.
