of section 6.1.7.1 of this Annex.

          6.5.5.6.         The torque limiter shall be deactivated when the engine speed is at idle if the conditions for its activation have ceased to exist. The torque limiter shall not be automatically deactivated without the reason for its activation being remedied.

          6.5.5.7.         Demonstration of torque limiter

          6.5.5.7.1.    As part of the application for type-approval provided for in section 3 of this Annex, the manufacturer shall demonstrate the opera- tion of the torque limiter either by tests on an engine dynamometer or by a vehicle test.

          6.5.5.7.2.    If an engine dynamometer test is to be carried out the manufacturer shall run consecutive ETC test cycles in order to demonstrate that the torque limiter will operate, including its activation, in accordance with the requirements of section 6.5, and in particular with those of section 6.5.5.2 and 6.5.5.3.

          6.5.5.7.3.    If a vehicle test is to be carried out, the vehicle shall be driven over the road or test track to demonstrate that the torque limiter will operate, including its activation, in accordance with the requirements of section 6.5, and in particular with those of section 6.5.5.2 and 6.5.5.3.

     (o)     Section 8.1 is replaced by the following:

'8.1. Parameters defining the engine family

    The engine family, as determined by the engine manufacturer must comply with the provisions of ISO 16185.'

     (p)    The following section 8.3 is added:

'8.3. Parameters for defining an OBD-engine family

         The OBD-engine family may be defined by basic design parameters that must be common to engine systems within the family.

         In order that engine systems may be considered to belong to the same OBD-engine family, the following list of basic parameters must be common,

                -          the methods of OBD monitoring,

                -          the methods of malfunction detection.

         unless these methods have been shown as equivalent by the manufacturer by means of relevant engineering demonstration or other appro- priate procedures.

         Note: engines that do not belong to the same engine family may still belong to the same OBD-engine family provided the above mentioned criteria are satisfied.'

     (q)     Section 9.1 is replaced by the following:

         '9.1. Measures to ensure production conformity must be taken in accordance with the provisions of Article 10 of Directive 70/156/EEC. Pro- duction conformity is checked on the basis of the description in the type-approval certificates set out in Annex VI to this Directive. In applying Appendices 1, 2 or 3, the measured emission of the gaseous and particulate pollutants from engines subject to checking for con- formity of production shall be adjusted by application of the appropriate deterioration factors
