The following definitions shall apply:

OJ L 252, 16.9.2016, p. 53 .

(1) In order to complete the framework established by Regulation (EU) 2016/1628, it is necessary to set out the technical and general requirements and test methods relating to emission limits, EU type-approval procedures for internal combustion engines for non-road mobile machinery, arrangements with regard to conformity of production and the requirements and procedures relating to technical services for those engines.

(2) By Council Decision 97/836/ECCouncil Decision of 27 November 1997 with a view to accession by the European Community to the Agreement of the United Nations Economic Commission for Europe concerning the adoption of uniform technical prescriptions for wheeled vehicles, equipment and parts which can be fitted to and/or be used on wheeled vehicles and the conditions for reciprocal recognition of approvals granted on the basis of these prescriptions (Revised 1958 Agreement) (OJ L 346, 17.12.1997, p. 78 ). , the Union has acceded to the Agreement of the United Nations Economic Commission for Europe (UNECE) concerning the adoption of uniform technical prescriptions for wheeled vehicles, equipment and parts which can be fitted to and/or be used on wheeled vehicles and the conditions for reciprocal recognition of approvals granted on the basis of these prescriptions.

(3) With the aim to ensure that the provisions on the construction of engines to be installed in non-road mobile machinery correspond to the technical progress, the latest versions of CEN/Cenelec or ISO standards which are accessible to the public should be made applicable as regards to certain requirements.

(4) Checks on the conformity of engines with the applicable technical requirements throughout the production process are an essential part of the EU type-approval process. Therefore, checks on the conformity of production procedures should be further improved and aligned with the stricter procedures applicable to road vehicles in order to increase the overall efficiency of the EU type-approval process.

(5) In order to ensure that technical services meet the same high level of performance standards in all Member States, this Regulation should set out the harmonised requirements with which technical services have to comply, as well as the procedure for the assessment of that compliance and for the accreditation of those services.

(6) For the sake of clarity, it is appropriate to align the numbering of test procedures in this Regulation with those in Global Technical Regulation No 11http://www.unece.org/trans/main/wp29/wp29wgs/wp29gen/wp29glob_registry.html and in UNECE Regulation 96OJ L 88, 22.3.2014, p. 1. ,

(10) auxiliary emission control strategy or AECS means an emission control strategy that is activated and temporarily modifies a base emission control strategy (BECS) for a specific purpose and in response to a specific set of ambient and/or operating conditions and only remains in operation as long as those conditions exist;
