Thus SQS supports and motivates its railway and rolling stock owner customers, or entities in charge of the maintenance of freight wagons (ECM), in the continuous improvement of their services and offerings while taking into account the economic aspects.


The SQS ECM certificate promotes acceptance by supervisory authorities and operators responsible for traffic on marked-out routes.

Maximum 3 years - in the context of continuous development, annually a maintenance audit and prior to expiration a re-certification audit is held.


The SQS certificate of conformity with ECM has international recognition.


The ECM certification system may be combined with ISO 9001 (Quality Management) and IRIS.
