on the fourth actuation of the service brake 'Control', after 3 actuations with vehicle stationary, either to full stroke or to the application of a 'Pedal Effort 35/00' not less than 685 N, whichever occurs first.
35.2.5.7.                    An energy generating device producing energy at negative pressure shall be capable of achieving the volume-pressure relationship required to satisfy the conditions specified in clause 35.2.5.6 within a time not exceeding 3 minutes with:
35.2.5.7.1.              the engine operating at not greater than 65 per cent of speed corresponding to either maximum power output or governed speed where the energy generating device is a vacuum pump; or
35.2.5.7.2.              the engine operating at idle speed with the gear selector in "neutral" position where the engine itself is the energy generating device.
35.2.5.8.                    In the case of a service brake system with a single 'Brake Power Unit 35/00', the design shall be such that the 'Stored Energy' device shall preferentially service the braking system if it also services other systems. In the case of a service brake system with 2 or more independent 'Brake Power Units 35/00', the design shall be such that at least one 'Brake Power Unit 35/00' shall preferentially service the brake system.
35.3.                                PERFORMANCE REQUIREMENTS
35.3.1.                          The vehicle shall be capable of meeting the range of performance tests set out in Table 1 of clause 35.3.3, subject to the general test conditions of Section 35.4 and the particular test conditions of Section 35.5. The sequence of testing may be in the order to set out in the Table. Where the sequence of testing is not in the order set out in the Table, the sequence shall satisfy the following requirements: Items 1 & 2, if conducted, must precede all other items; Items 3-10 must be in sequence; Items 11-13, if applicable, must be in sequence; Items 14-15 must be in sequence; and Items 16-17 may be conducted at any time between or after the above sequences, except that in the case where service brake fade testing is carried out in accordance with clause 35.5.9.2, Item 9 is not subject to the above sequence requirements.
35.3.2.                          Not used.
