The testing items for insulated gloves include the following aspects:
1. Appearance inspection: mainly check whether there are obvious damages, cracks, or scratches on the surface of the gloves, and also check whether the joints of the gloves are intact.
2. Size inspection: According to the usage requirements of the gloves, check whether the length, width, finger length, and finger circumference of the gloves meet the standard requirements.
3. Insulation resistance measurement: Use an integrated testing instrument to measure the insulation resistance of gloves, and the voltage and time of the test are determined according to the usage requirements of the gloves. The final measurement result should meet the corresponding standard requirements.
4. Bubble leakage test: Place the gloves in water and sequentially increase and decrease the pressure to detect any bubble leakage. If there are bubbles or leaks in the gloves, it indicates that the gloves are defective.
5. Tensile strength test: The tensile strength of gloves is tested by stretching them under specific conditions, and the test results should comply with relevant standards.
In summary, the inspection items of insulated gloves mainly include appearance inspection, size inspection, insulation resistance measurement, bubble leakage test, and tensile strength test.
