4.2.6 Axles axle

The axle shall be free of loosening, shedding, deformation or damage during use, and the wheels shall not be loosened and shall meet all the tests of clause 5.


4.2.7 Wheels wheels


The wheel should be made of non-slip material, according to 5.3 test when the anti-slip coefficient is greater than 0.3.

After the test of the terms, the wheels shall not be cracked, loosened or deformed.


After 5.7 tests, the front and rear wheel size consistent, not serious wear and tear.


4.2.8 Self-locking fixings Self-locking devices

The supplier shall specify the correct use and failure of the self-locking device in the specification.


4.2.9 Mechanism to reduce the speed


It can not be loosened after testing by clause 5.

Brake device should be smooth deceleration, can not make the scooter stop.


Strength strength


All parts can not be damaged or damaged after the test of clause 5, should meet the corresponding requirements in the standard.

Test method


General requirements


The test sample should be properly assembled and commissioned according to the instructions provided by the supplier

The same two samples were tested in the order of 5.2


5.2 Order of tests


5.2.1 Specimen A Model A

Pattern A is tested in the following order


  1. A) test of external finish (see 5.8) Visual inspection (5.8)


  1. B) wheel adhesion test (see 5.3) Wheel slip test (5.3)
  2. C) endurance test (see 5.7) Durability test (5.7)


5.2.2 Specimen B Model B


Sample B is tested in the following order:

  1. A) static load test of the deck (see 5. 4.1) Pedal static load test


  1. B) static load test of the steering column (see 5.4.2) joystick static load test


  1. C) drop test (see 5.5) drop test
  2. D) impact test against front wheel (see 5.6) front wheel impact test


5.3 Wheel adhesion test


The wheels will be pulled through a surface with a surface roughness of 1.5-2.00 μm to the oil-free disc.

Apply 100 N (F1) vertically above the wheel and pull the wheel horizontally at the center of the wheel to glide at the metal surface at a speed of 1 mm / s to calculate the magnitude of the tension (F2).

5.5 Drop test drop test


Cylindrical weight impact pedal center

Test Equipment:


  1. A) cylindrical weight (20kg) diameter of 100 mm


  1. B) rubber washer with a thickness of 17 mm, a hardness of 70 (shore A), and a cylinder size
  2. C) guide tube


Heavy weight free fall off the impact pedal center 3 times, fixed scooter to prevent overturned.


The weight falls from the 300mm height to the center of the impact pedal.

If the pedal or joystick is a plastic material, keep the scooter at least ± 6 hours at -5 ± 1 ° C and take 1 minute after the test and complete the test within 5 minutes.


Impact test on front wheel


The scooter can withstand 135J (J = 1 / 2mv2 {v = s / t}) or hit the front wheel at a rate of 4.5 ± 0.5m / s

This test is designed to ensure the strength of the front wheel group.


Endurance test


Durability test must be a complete scooter, the scooter placed in the test drum shown in Figure 5, to 0.5m / s speed 12Km (400min), pedal center load 90kg, handle load 10kg,

The scooter wheel passes through two ramp blocks for 1.5 s / time
