WHY PURCHASE FROM US?

Have a question you don’t see answered here? Feel free to give us a call at 800-353-3411, ext 4052 or use the contact form below.

JM Test Systems has a large inventory of gloves covering Class 00 (500 volts) to Class 4 (36,000 volts). We offer gloves from the industry leaders including Salisbury, Chance, PIP, and OEL.

JM Test has inventory at multiple locations. This allows us to fill your order quickly and save you transit time and cost.

All electrical gloves purchased from JM Test Systems are tested to ASTM D120 and ASTM F496 Standards. These are the same standards that we test gloves at that have been in service. Many suppliers do not perform this testing on new gloves prior to the shipment of the order. Our priority is keeping you safe. We can also stamp your gloves with a unique ID number to help with tracking and we auto-enroll you in our retest program that is designed to help you manage your glove rotations and keep you compliant. All gloves come complete with current date stamps.

JM test keeps inventory on leather protectors, glove bags, and glove dust to go with your electrical gloves. All of these items are available in our custom glove kits.

RUBBER GLOVE TESTING LAB 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:

STEP 1

RECEIVING

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.
STEP 2

WASHING

Gloves are washed in our commercial washers with detergents that disinfect and remove contaminants. These detergents are specifically designed for the use on rubber insulative equipment. The gloves are then dried for testing
to prevent flashover.

STEP 3

ELECTRICAL GLOVE TESTING

JM is capable of testing all gloves as classified by ASTM. All testing is performed using AC current 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.
STEP 4

VISUAL INSPECTION

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, looking for any defect that may compromise the integrity of the glove. 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.
STEP 5

FAILS

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.
STEP 6

STAMPING

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 the test, along with the maximum field use voltage is 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
STEP 7

FINAL INSPECTION

Final Inspection 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.
STEP 8

PACKAGING

The inside of each glove is powdered to help keep the end users hands dry for the initial use. For easy identification, each pair of gloves is packaged in a clear bag and heat sealed. The heat seal allows customers to know when a pair of gloves has 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.
STEP 9

FINAL

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. Read more in our GLOVE TESTING FAQ

Safety Glove Size Charts

Taking the time to accurately measure and select the correct glove size is crucial. Without correct-fitting gloves, employees have a higher risk of being unprotected, which can lead to unwanted hand injuries.

MEASURING WIDTH

Measure the width of the dominant hand with a soft cloth tape measure. The dominant hand measurement is preferred (right if you’re right-handed and left if you’re left-handed) because it’s the largest hand.
US Sizes EU Sizes
6 - 7 Inches XS 152 - 178 Milimeters EU - 6
7 - 8 Inches S 178 - 203 Milimeters EU - 7
8 - 9 Inches M 203 - 229 Milimeters EU - 8
9 - 10 Inches L 229 - 254 Milimeters EU - 9
10 - 11 Inches XL 254 - 279 Milimeters EU - 10
11 + Inches XXL 279 + Milimeters EU - 11

MEASURING LENGTH

Another method to determine glove size is measuring the length of your hand. This is done by measuring from the bottom edge of the palm to the tip of the middle finger as pictured in the graphic.
US Sizes EU Sizes
6 5/16Inches XS 160 Milimeters EU - 6
6 3/4Inches S 171 Milimeters EU - 7
