The testing standards for the anti-static and insulation resistance testing machine of finished shoes are mainly based on the relevant regulations on the anti-static and insulation resistance performance of shoes. Common testing standards include international standards, national standards, and industry standards. Here are some commonly used testing standards and methods:
1. Anti static performance test
The main function of anti-static shoes is to prevent static electricity from being generated by the human body, avoiding damage to electronic devices or harm to the human body caused by static electricity. The anti-static performance test usually includes the following contents:
Static resistance value test: The anti-static performance of the shoe is tested based on the resistance of the sole, usually requiring the shoe's resistance to be within a certain range.
The testing method is to measure the resistance value of shoes in a standard environment using specific testing equipment, such as an anti-static tester.
Sole durability test: Test whether anti-static shoes still maintain effective anti-static performance after long-term use.
2. Insulation resistance test
The testing of insulation resistant shoes usually requires the shoes to effectively isolate the current and prevent it from being transmitted to the human body through the shoes. The insulation resistance test standards usually include:
Electrical insulation testing: High voltage power is usually used to test the electrical insulation performance of shoe soles. The standard requires that the sole of the shoe should not break down at a specific voltage and maintain insulation.
Insulation resistance value: Test the insulation resistance of the shoe sole when high voltage is applied. During the testing process, the resistance value of the shoes should be higher than the minimum required value, usually above 100M Ω.
3. Standardized testing environment and methods
The testing environment usually needs to meet certain standards, such as temperature, humidity, etc., which must be within the specified range to ensure the accuracy of the test results.
Temperature and humidity control: Testing is typically conducted at room temperature (20-25 ° C) and relative humidity (40-60%).
Applying voltage and current: During testing, a certain voltage (such as 500V, 1000V, etc.) needs to be applied, and the current passing through the sole of the shoe needs to be measured.
4. Testing equipment
Anti static tester: used to measure the static resistance of shoes.
High voltage testing equipment: used to test the insulation resistance of shoes, usually requiring the testing equipment to generate a certain voltage and conduct safety testing.
5. Inspection report and qualification standards
After testing, a testing report will be issued, which will include data such as the testing equipment, methods, and measured resistance values. If the shoes meet the corresponding standard requirements, they can be judged as qualified anti-static and insulated shoes that comply with safety protection standards.
These standards and testing methods are mainly used to ensure that finished shoes can effectively prevent static electricity accumulation and provide electrical insulation protection, and are widely used in the electronics industry, medical industry, and high-risk electrical environments.
