Electrical Glove Testing Services
JM Test System’s is fully accredited for testing high voltage rubber protective goods. Our rubber testing lab provides electrical glove testing services to ASTM D120 & ANSI F496 standards. Rubber sleeves are tested to ASTM D1051 & ANSI F496 standards.
High voltage gloves testing requirements
OSHA requires electrical glove testing to be performed at least every 6 months after first issuance of a set of gloves. JM provides this testing service to help customers stay compliant. We also provide an avenue for qualitatively trained technicians to visually inspect the end users equipment for any damage. OSHA also requires that a date of test be affixed to the equipment, proving that it has undergone testing within this specified time period. JM provides this through our stamping practice to help customers stay compliant.
Our qualified staff, with 20 years of experience, serves customers on a daily bases to help them stay compliant; and above all, help keep their employees safe. Our dedicated staff is here to help our customers understand the importance of what we do, how to use their equipment properly, and help educate on the best care/maintenance practices.
Rubber Glove Testing Lab’s Process
Our process of handling customers equipment follows the best suggested process, set forth by ASTM, the governing body over testing materials. Our process is as follows:
- Glove Receiving
- Washing the Gloves
- Dielectric Test
- Visual Inspection
- Glove Testing Fails
- Stamping & Record Keeping
Gloves start in our receiving department, and are entered into our system by pairs to accurately detail the quantity and characteristics of each glove. They are brought into the washroom to start the cleaning process.
Gloves are washed in our commercial washers with detergents that disinfect and remove contaminants. These detergents are proven safe for industry use on rubber protective equipment. The gloves are then dried for testing to prevent flashover.
Electrical Glove Testing
JM is capable of testing all gloves as classified by ASTM. All testing is performed in accordance with ASTM testing standards, which are nationally recognized by OSHA to be the industry standard.
Our technicians prep the dielectric gloves testing machine to ensure all settings meet these standards. The machines grounding rods act as a ground reference if the electricity punctures through the glove. Gloves are hung individually from the rack of the tester by pins. As testing begins, the gloves are filled with water and the tester closes to safeguard our employees from electric shock potential. The water in the tank is energized to the appropriate test voltage. Voltage is applied for at least one minute for retest gloves and three minutes for new gloves. Electrical current levels are monitored during this time to ensure current leakage is not in excess. The gloves are then dried a second time.
Gloves that have passed dielectric testing are then moved to our inflation area where visual inspection is performed. Compressed air is used and regulated to ensure that gloves are inflated to ASTM specifications and not overinflated. Extra bright lighting is located at this station to ensure that no defects are missed. Our technicians inspect the entire surface area inside and out, paying special attention to the palms and fingers. All types of mechanical damage are caught at this stage; even those that pass dielectric testing. This is the most important stage in our process seeing as this is the last step where failures can be caught. Only our most experienced, well qualified, technicians perform this task.
Electrical failures occur due to a breakdown in the insulating properties of the rubber. Any glove that fails during dielectric testing is removed from the tester. The electricity punctures through the rubber, introducing electrified water into the grounded water, thus, causing what’s known as a “dead short”. The glove is, defaced to ensure no future field use, and the remaining gloves are cycled through testing again to ensure the full duration of testing time is achieved. All electrical and visual failures are logged and turned into our administration personnel to inform the customer of the failures. New gloves are kept in stock and customers are given the option to replace any failures. All new gloves are run through appropriate testing and visual inspection.
To stay compliant with OSHA, all passing electrical glove testing pieces are stamped with the necessary information along with personalized or informative details requested by our customers. A unique JM stamp detailing the voltage applied during test, along with the maximum field use voltage are applied. The gloves are then stamped according to the date they are tested, this allows customers to easily identify gloves that are in and out of compliance. Personalized information for tracking such as employee ID #’s, employee names, rotation numbers/letters, and date due back for testing can be requested to be placed on the gloves. For customers that do not have a unique identifying system for their equipment, an identifying number is applied to the inside of each glove.
The beginning of our quality assurance begins when a lead technicians is called to inspect all technicians’ stamps for accuracy. All stamps are checked against any paperwork submitted by our customers to ensure special requests are being met; and, all information has been logged correctly by our Receiving Dept.
For easy identification each pair of gloves are packaged in clear bags and heat sealed. The heat seal allows customers to know when a pair of gloves have been issued out for service. Labels are applied to boxes to help our customers to easily identify contents without our customers having to open each box. This makes for easy distribution back to their employees and storage. Qualified Technicians generate a test report and send with each order for record keeping purposes.
Once all equipment has been tested and inspected it is sent back to you ready for use! Need new gloves? JM Test Systems also sells new gloves which are tested prior to being shipped to you.
JM Test Systems’s electrical safety lab provides testing on a wide range of products. Services include gloves (lineman’s / arc flash glove testing), blankets, covers, sleeves, sticks, grounds, and more. Our glove testing labs are located in Baton Rouge Louisiana, Mattoon Illinois, Clute and San Angelo Texas.
