This standard is based on the durability test part of 15):3191:993 Wheel Durability Test Method (First Edition), and is based on GB/T42-9842 Light Vehicle Tire Durability Test Method. The main technical contents are consistent with the international standard.
The main differences between this standard and the original standard are as follows:
The main technical six changes require the original cup violation light cross wheel look forward to the two tires of the slow test method, with the first line tire as the second point. The private inflammation tire test gas is described in the form of "note",! 2! The road craftsman has tested the gas flow jade girl, the test negative rate is small, the original non-test time is guaranteed, the technical requirements (3) the test temperature is selected, the measurement unit of the five gas is collected,
? Not standard and international standard! The main difference (1: According to the technical requirements of the national youth reserved for the car bias tire (2) According to the existing test equipment, the international indication note is selected when the diameter groove 170m three 1Ym test machine, 3) The increase in the time of the reverse rotation specified by the starter should be within 5min. (1) The following are the test conditions for the replacement of light tires: This standard is implemented from the date of 5B/T4502-1984. The standard was issued by the Ministry of Industry and Information Technology of the People's Republic of China. The six standards are the technical requirements for the international standardization of tires. The drafting unit of the standard is: Beijing Institute of Technology, ... , the development of international work, is carried out through the IS) technical exchange of the six professional bodies have the right to participate in the professional technical committee. With the IS) related to the international organizations (including official and unofficial), the world can coordinate this work in the technical standardization of all parties, and work closely with the International Electrical Products Association, the technical committee formally implemented by the State Grid standard proposal, when the member of the system to send the vote, the publication of the international standard proposal of at least 75 members of the medical vote.
International Standard 3) 1019 "is the tire and valve injection technology of the wheel manufacturing technology of TS0/1C31/SG3 only 2 wheel lubrication technical specification committee.

3 Requirements
After the durability test is carried out under the conditions specified in this standard, the tire pressure should not be lower than the specified initial pressure; the wheel appearance inspection (tread, grease, core, airtight lip, belt, tire) should not have any defects such as detachment, cracks, wire breakage, wire fracture, flower, joint cracking, and replacement.

5.2. will be released after the tire pressure is more close to the words to love! You will park on the in. Now the mother light sound to 5.2.? According to the above recording prepared for the tire wheel red The test shall be carried out on the test stand, so that it is close to the outer surface, and the test shall be carried out according to the specified dosage plan.
5.2.3 The test period is 38+5, and the fiber source drift measurement shall be 150-10000m from the wheel. The test process shall not be artificially cooled.
5.2.4 The test procedure shall be carried out continuously and shall not be interrupted for a long time. The air pressure shall not be readjusted. The test shall not be repeated. 5.2.5 The tires shall be tested according to the regulations or 3 tests. After the tires are cooled, the tire pressure and size shall be measured immediately. After that, the tires shall be properly inflated and the appearance shall be inspected.
6 Test records
The wheel test shall record and record the following items: a) factory inspection, brand, structure, specification, grade, production number; 6) light rim specifications;
air pressure changes:
d! External theory, section changes:
+) test duration, test load and test mileage; at the end of the test, the tire pressure, current situation and photography phenomena! ) Theory: "passed the test" or "not passed the test": h) test month:
In addition to the allowable deviations specified in the current tire standards, the allowable deviations of other test conditions are listed in the table? 3. The allowable deviation of the test trend is -hPa. The test results are as follows: tt|| The gas is -hPa. The test results are as follows: tt| ...
