| Summary: | NBR gloves are considered to be one of the most extensively used safety goods worldwide Disposable gloves can be broadly divided into two many areas namely medical-health and non-medical. The gloves provide the necessary barrier protection against bacteria, viruses and chemical penetration. In the midst of the Covid-19 pandemic, it is even more important to wear appropriate gloves to increase protection for frontlines working to control the spread of the Covid-19 virus and resulting diseases. NBR gloves are required in places such as workshops, scientific laboratories, hospitals, farms and factories, gardens and electrical installations. In the current work, three different test methods for the detection of defects namely pinhole, thin spot and thin area in gloves are studied and compared. The test methods are tensile test, water-leak test, and electrical insulation test. Mechanical and dielectric integrities of 4-gram (0.07 mm thickness) nitrile-examination gloves with defects such as sub-mm pinhole and a thin spot in the obscured finger region, as well as a relatively large thin area, are measured and compared. Mechanical test methods were the water-leak test in accordance with the ASTM standard and the tensile test accordance to EN455 standard, normal glove is required to pass the force-at-break of 6 N in the tensile test, but this was significantly reduced (100 V was required to detect glove pinhole defects while in motion. |
