applications shall be made when the initial temperature is below 100 °C. The temperature shall be measured in accordance with the provisions of paragraph 2.1.4.4. of this annex.
4.3.2.  Brake applications shall be made from an initial rotational speed equivalent to that given in row (A) of the table under paragraph 2.1.1. of Annex 3 to this Regulation, and the brake shall be applied to achieve a mean torque equivalent to the deceleration prescribed in that paragraph. In addition, tests shall also be carried out at several rotational speeds, the lowest being equivalent to 30 per cent of the maximum speed of the vehicle and the highest being equivalent to 80 per cent of that speed.
4.3.3.  The mean braking torque recorded during the above cold performance tests on the linings being tested for the purpose of comparison shall, for the same input measurement, be within the test limits 15 per cent of the mean braking torque recorded with the brake linings conforming to the component identified in the relevant application for vehicle type approval.
4.4.  Type-I test (fade test)
4.4.1.  Heating procedure
4.4.1.1.  Brake linings shall be tested according to the procedure given in paragraph 1.5.1. of Annex 3 to this Regulation.
4.4.2.  Hot performance
4.4.2.1.  On completion of the tests required under paragraph 4.4.1. of this annex, the hot braking performance test specified in paragraph 1.5.2. of Annex 3 to this Regulation shall be carried out.
4.4.2.2.  The mean braking torque recorded during the above hot performance tests on the linings being tested for the purpose of comparison shall, for the same input measurement, be within the test limits 15 per cent of the mean braking torque recorded with the brake linings conforming to the component identified in the relevant application for vehicle type approval.
5.  Inspection of brake linings
 Brake linings shall be visually inspected on completion of the above tests to check that they are in satisfactory condition for continued use in normal service.

Annex 8
  Special requirements to be applied to the safety aspects
of complex electronic vehicle control systems
1. General
 This annex defines the special requirements for documentation, fault strategy and verification with respect to the safety aspects of Complex Electronic Vehicle Control Systems (definition 2.3. below) as far as this Regulation is concerned.
 This annex may also be called, by special paragraphs in this Regulation, for safety related functions which are controlled by electronic system(s).
 This annex does not specify the performance criteria for "The System" but covers the methodology applied to the design process and the information which shall be disclosed to the Technical Service, for type approval purposes.
 This information shall show that "The System" respects, under normal and fault
