ISO is a worldwide federation of national standards bodies (ISO member bodies). The development of international standards is generally carried out by ISO technical committees. Each member body has the right to participate in the development of the project committee. International organizations that are liaison members of ISO, governmental and non-governmental organizations, can also participate in this work. IS and the International Electrotechnical Commission (IEC) collaborate in all areas of electrotechnical standards. Draft international standards adopted by the technical committee are circulated to their member bodies for voting. As an international standard, it is required to vote for at least 5% of the member bodies.

This standard adopts the definitions specified in GB/T5263.1 and GB1B/T17125. 4 Test parts
4.1 The guard test fence should be taken from the batch production: the product drawings should be kept in accordance with the manufacturer's instructions for operation and maintenance. During the test period, the non-navigation or rotating guard should be fixed. The rotating guard should rotate. The guard should be connected with the transmission shaft with a length of 1 (GB/T17126). The test process card should use a protection rate. The test results of the sample are valid for the model of the device with a length of 100 mm or shorter.
4.2 The test cost is to be carried out at an ambient temperature of ~-35°C or at a temperature of 5V<:5°C. 4.3 The speed of the test for the rotating device should be 1 (((r/min. 5 Test equipment
5.1 The grinding arch test cover should be an integral body that can horizontally support the rotating or non-rotating device and can rotate the driving shaft at a speed of 1000rmi. The device is applicable to all transmission shafts specified in B/T1126. The National Quality and Technical Supervision Bureau approved 20C-C9-C1 on March 16, 2000 for implementation

The size and shape of the body should ensure that the salt water drop is zero or the powder is evenly distributed . Its shape should be such that the spray curtain drops collected on it will not drip on the shield.
5.2 The test water should be potable water.
5.3 The building blocks should be of equal quality to the whole building blocks and the building blocks of the machine. 5.3.1 The organic powder should be low-temperature powder with a maximum moisture content of 12% and a maximum particle size of ?mm. 5.3.2 The inorganic powder should be a pure fertilizer obtained by the production of iron ore by treating steel or fermented iron. Its main component is calcium sulfate. The minimum content of the following is

5.4 The test salt solution should be made by dissolving sodium chloride in water. The concentration is 50g/g/cm3. Sodium oxide becomes white, and its aqueous solution should be various, and there should be no zinc in the filter paper. The dry salt is calculated on the basis of the back, and the steel production should be In the test, the total impurity content is not more than 0.4%. Before the test, the solution should be filtered to remove the solids in it to avoid the tower clogging and damage to the spray device. During the test, the spray device installed on the transmission shaft is operated for 6 hours. 6.1 According to the test procedure specified in 6.2, when the transmission shaft rotates, the transmission shaft is stretched from the maximum length to the minimum length within 6 minutes.

Before starting the next test, the transmission shaft with the windshield is immersed in water (see 5.2: After taking it out of the water, the water on the windshield and the transmission shaft is removed under the condition of heavy weight: b) At the loss degree, the gas contains new particles that meet the requirements of 5.3. The micron degree is 0.5kg/ m*, run for 120h. c) At ambient temperature: spray the atomized water solution (see 5.4) at a speed of 72 (L/h)/m, run for 2h. After running for 2h, take out the drive shaft and the guard, 46!
d) At ambient temperature, run for 48:
6.3 Before and after the test specified in 6.2, measure the torque of the fixed guard sleeve when the drive shaft rotates at a speed of 100C+/min.
7 Radial and axial loading test
7.T After the wear test, the transmission shaft with expansion should be able to pass the normal initial load comparison test specified in 3.3 of GB/T5263.1200.
7.2 The transmission shaft with guard should also pass the normal temperature shaft series load test. The transmission shaft and the guard are stationary, and a 100N shaft load is added between the guard and the driving shaft. Or the load is added twice. After the loading tests of 7.3, 7.1 and 7.2, observe and record the expansion, deformation, plastic deformation and component disintegration.
