3.6 After passing the wheels verification, the lead seals for stationary verification shall still be remained, and a wheels verification compliance marks shall be attached to the face of the taximeter. If the instrument has no stationary verification compliance mark and lead seals or the lead seals is damaged, an application for wheels verification shall be rejected.
3.7 After a taximeter is installed, the front end of the joint connecting it to the car body shall be lead sealed by the installation firm, and the tail end lead sealed by the verification body after it passes the wheels verification. Neither of the aforesaid lead seals should be enveloped.
3.8 When the seals are removed for repair, the repair firm shall attach lead seals at two points on the left and on the right and remove the original wheels verification tag. The taxi operator shall apply for re-verification within 3 days commencing from the removal of the seals. If the taximeter passes the verification, lead seals shall be attached again onto the original places in accordance with the requirements of Section 3.7.
4. Verification, Inspection and Maximum Permissible Errors
4.1 Verification and inspection equipment: certificates of traceability shall be provided.
4.2 Stationary verification items are as follows:
4.2.1 Taximeters are checked in compliance with the provisions set forth in Sections 3.1,
3.2, and 3.5 of this Specification.
4.2.2 Differences between the actual measures and the set values of distance count, time
count and night surcharge of a taximeter are within the specified maximum
4.2.3 A taximeter shall work normally when the power voltage varies between 9V and 16V.
Original values shall be displayed when the voltage declines to 6V and then return to
12V within 10 seconds. The displayed fare shall not be changed after the power is
switched 5 times continuously under an ordinary working voltage.
4.2.4 Speed measured when a taximeter converts to time-based pricing does not exceed the specified maximum permissible errors.
4.3 Items of wheels verification (including running verification) are as follows:

3.4, 3.6, 3.7 and 3.8 of this Specification.
4.3.2 Differences between the actual measures and the set values of distance count of a
taximeter are within the specified maximum permissible errors.
4.4 Maximum permissible errors of verification are prescribed as follows:
4.4.1 Stationary verification:
(1) The maximum permissible errors of speed for converting time-based pricing of a taximeter are 10 %.
(2) The maximum permissible errors of time for stationary verification of a taxi-meter are 2 %.
(3) The maximum permissible error of distance for stationary verification of a taximeter is +2 %, with no negative maximum permissible errors.
