6.4.2 The overall mass of the sightseeing vehicle is measured as follows. a) The sightseeing vehicle is in a no-load state, it shall be driven from the one direction to the weighing platform and stop at the center of the
weighing platform. During the measurement, the sightseeing vehicle stops and the engine or motor is turned off. Then the sightseeing vehicle is
turned 180??, to measure the average value again.
b) The method for determining the mass of compartment is the same as
above.
6.4.3 The mass of front- and rear-axles of sightseeing vehicles is measured as follows.
Sightseeing vehicles are in no-load condition and fully-loaded condition respectively. They are first driven from one direction to the weighing platform, to weight the front-axle and rear-axle in turn. During measurement, only the wheels of the axles under test are allowed to stop on the weighing platform. The prototype remains horizontal. Let is stop stably and the engine goes out (or the motor is turned off). Then the sightseeing vehicle is turned 180??, to measure the average value again.
Axle mass distribution correction is as shown in formula (1) ~ formula (5). 6.19.2 The intensive test procedure consists of several identical cycles. The procedure for the first cycle in the test is as follows.

The sightseeing vehicle continues running forward, turns left at 90?? to enter the straight line runway section, and continues running forward, turns left at 90?? to reach the starting point.
6.19.3 The test process shall meet the following requirements.
a) Operating speed. The prototype shall be subject to a reliability-
strengthened test operation at the maximum safe speed. The sightseeing
vehicle shall run at a 90?? turn and shall make a turn with the minimum
turning radius.
b) Daily workload. The daily continuous operation volume shall be not less than 8 h; the sightseeing vehicle with the operating speed greater than 27 km/h shall circulate at least 75 cycles per hour; the sightseeing vehicle with the operating speed of 18 km/h ~ 27 km/h shall circulate at least 50 cycles per hour; the sightseeing vehicles with a speed of less than 18 km/h shall circulate at least 25 cycles per hour.
c) Prototype maintenance. The prototype can be routinely maintained as
specified in the instruction manual.
d) After the test is carried out for 100 hours, change to the reversed direction. 6.19.4 Calculation of reliability index MTBF is as shown in the formula (10). Where.
Tz - Pure operating time, in hours (h);
r - Number of fault equivalents (see Appendix A).
Effectiveness A is as shown in formula (11).
7.2 Type inspection
7.2.1 Type inspection shall be carried out in any of the following situations. a) When a new product or an old product is subject to trial production
finalization after transferring to another plant;
b) When the product production is restored after suspension for a year; c) When the higher quality inspection agency proposes a type inspection; d) After the formal production, if there are major changes in structure, materials and processes affecting the product performance and quality;
e) When there is a significant difference between the exit-factory inspection result and the last type test.
