1) IEC (International Electrotechnical Commission) is an international organization for standardization that includes all national electrotechnical committees (IEC National Committees). The purpose of IEC is to promote international cooperation on all issues related to standardization in the electrical and electrical fields. To this end, IEC, in addition to other activities, publishes international standards. These international standards are entrusted to various technical committees. Any IEC National Committee that is particularly interested in the project can participate in the formulation work. National standards that collaborate with IEC. Governmental and non-governmental organizations can participate in this formulation work. IEC and the International Organization for Standardization (ISO) work closely together under the terms of the agreement between the two organizations. 2) IEC's correct resolutions or agreements on any technical issue are proposed by the technical committees on behalf of all national committees that are particularly interested in the issue. These resolutions and agreements try their best to express the practical consensus on the issues involved. 3) These resolutions and agreements published in the form of standards, technical reports or guidelines are available for international use in the form of recommendations and are accepted by the national committees of various countries in this sense. 4) In order to promote the unification of international standards, IEC National Committees are responsible for explicitly adopting IEC International Standards as their national and regional standards to the greatest extent possible. Any differences between IEC standards and corresponding national or regional standards should be clearly indicated in the national and regional standards.
International Standard IEC1133 was developed by IFC Technical Committee 9, the Technical Committee for Traction Electrical Equipment. This first edition made a technical revision to IEC165 published in 1973 and IEC49G published in 1974, and replaced them.

3Test classification and implementation methods
3. 1 Test classification
3.［.1 Factory test
Rules for electronic equipment for railway locomotives and rolling stock Part 1: General requirements and tests for electrical equipment General requirements for explosion-proof electrical equipment for explosive atmospheres Explosion-proof electrical equipment for explosive atmospheres
Explosion-proof electrical equipment for explosive atmospheres "ad\(ncgIEC79--1) Explosion-proof electrical equipment for explosive atmospheres Increased safety electrical equipment\" Explosion-proof electrical equipment for explosive atmospheres Intrinsically safe circuits Electrical equipment "Electrical terminology Explosion-proof electrical equipment for explosive atmospheres Measurement of internal noise of locomotives and rolling stock (nenIS033B1: 1976) Weight measurement method for industrial and mining electric locomotives (neJISE4011: 1979) Manufacturers should conduct tests on each electric locomotive according to the items specified in the factory test, and only leave the factory after passing the test. 3. 1. 2 Type test
Type test is a comprehensive assessment of whether the basic parameters, structure and performance of the electric locomotive meet the requirements of the technical standards. The electric locomotive for type test should be selected from the first batch of manufacturing or batch production after passing the factory test. The electric locomotive should be tested with load or light load before the type test, and adjustments to the electric locomotive are allowed during the test run. The number of single-trip test runs is generally stipulated as follows:
For electric locomotives of 75t and above: rated hourly speed × 100h. For electric locomotives of 75t and above: rated hourly speed × (50~100)h mileage. 3.1. 3 Research test
If the manufacturer has special requirements for the product according to needs or users, they can be used as research test items after consultation and agreement. The results of research tests are usually not used as the basis for assessment and acceptance of electric locomotives. 3.2 Test methods
3. . 1 Test conditions
The test site for the static test or on-road test of electric locomotives shall comply with the requirements specified in the relevant electric locomotive technical standards. 3.2.2 Test items
The test items shall be selected in accordance with the test contents specified in Appendix A Test Guide and the technical standards for various electric locomotives. The flame retardant performance test of explosion-proof and special battery electric locomotives shall be carried out in accordance with the relevant provisions of GB3836.1~3836.4. 1997-12-07

4 Static test
4.1 Clearance inspection
JB/T31141997
The purpose of the clearance inspection is to ensure that the outer dimensions of the assembled electric locomotive meet the requirements of the relevant electric locomotive technical standards. The parts that need to be adjusted according to the degree of wear of the flange (such as the obstacle remover, the sand pipe should be properly adjusted. 4.2 Weighing test
Measure the static total weight, axle weight and wheel weight of the locomotive in the ready state, and the accuracy of the measuring equipment should be stated. The measurement method shall be carried out in accordance with GBT10762.

The operating handle of the air brake should be flexible and easy to rotate when in the middle support position. Check that the pressure change, action time and warning sound of the operating handle when changing positions are in compliance with the requirements of the corresponding locomotive technical standards. 4 Comprehensive air tightness and operation test of compressed air equipment 4.4.! Air pipeline system air tightness test a) When the door leading to the pipeline part is closed, start each air compressor separately. When the motor voltage is rated, the time for the main air pressure to rise to the "north fixed air pressure" value should comply with the requirements! 6) Inflate the main air cylinder to the specified maximum working pressure, stop the compressor and close the valve, conduct an exposure test on each storage circuit of the electric locomotive (main air cylinder and main air cylinder pipeline, train pipeline, brake cylinder pipeline, control circuit, overturning sound circuit, etc.), and measure the pressure drop of the main air cylinder and each part of the pipeline within the specified time, which should comply with the technical standards of the electric locomotive. 44.2 Compressed air equipment action test control

4.5.1 Operation and emergency brake test
The purpose of the test is to determine whether the operation of the brake system and the force applied to the brake pads meet the design requirements together with the line brake. Check whether the brake lever transmission device meets the requirements, check the air supply, air cylinder and brake valve at the maximum pressure: check whether the air supply system has been adjusted to be able to supply air to the pipeline and the national air supply at a certain pressure and rate. Perform an operation brake test when it is stationary, and check whether the brake can be operated and carried out under different operating conditions. c) For the middle position of emergency braking and running, the brake cylinder pressure and the working time should be measured: d. The sum of the braking forces applied to the brake shoe should be measured to calculate the static braking rate, that is: the sum of the brushing forces applied to the brake shoe × 100% of the actual braking force of the locomotive
For locomotives equipped with brake devices and only manual brushing: a certain force can be applied to the brake device with a torque wrench: the force acting on the shoe can be measured to calculate the braking rate. This test should be carried out within the adjustable travel of the brake chamber for locomotives equipped with a brake adjuster. For locomotives without a brake adjuster, run within the maximum and minimum range,
In the above case, the sum of the braking forces acting on the brake shoe should not be less than the design specified value. 2

Each circuit shall be subjected to a voltage withstand test to ground, while other circuit sources shall be grounded. If necessary, the contactor and switch shall be closed or short-circuited to ensure that all parts of the circuit are connected. Measures shall be taken to avoid abnormal voltages that may appear at certain points due to the influence of capacitance or inductance.
