Testing and Inspection Services Offered

  • Rubber gloves (Class 00 through Class 4)
  • Rubber sleeves
  • Rubber blankets
  • Insulated "hot sticks"
  • Insulated line hose
  • Fiberglass bucket liners

Dielectric testing with AC (up to 100kv AC) current is also available for insulated aerial lifts (bucket trucks and digger trucks) at our facility or your fleet headquarters.


Testing Process

Testing of gloves, sleeves and blankets begins with installation of a non-conductive label that identifies a particular item. This label is used for tracking and documentation and also allows the protective equipment to be assigned to specific user-employees by a personal number and a customer code.

Gloves and sleeves are first washed in a mild soap solution and dried. The items are then inflated and carefully inspected for cuts, tears, punctures, scratches, abrasions or any other conditions that could adversely affect the dielectric integrity of the item. If any of these conditions are present, the item fails the visual inspection and is rejected and immediately rendered unusable to prevent accidental reuse.

Gloves, sleeves and blankets then undergo an electrical test as specified by the "class rating" of the item and the ASTM and OSHA Standards (maximum 40kv A.C.). Again, any item that fails the electrical test is rejected and immediately rendered unusable.



A complete record of the testing is documented on a test result sheet. One copy of the results is returned with the test order and a copy is kept at the Test Lab in a file maintained for each customer.


Equipment Disposal and Replacement

Any item that is rejected can be returned to the customer or disposed of by us depending on the individual customer's needs. For the convenience of our customers, you may choose to replace rejected gloves or sleeves from our inventory and avoid lengthy factory lead times.

OSHA requirements in 29CFR 1910.137(b) cover the "in-service care and use" of rubber insulating equipment. This section lists testing criteria and establishes minimum test intervals in Table I-6.

Type of Equipment When to Test
Rubber insulating line hose Upon indication that insulating value is suspect
Rubber insulating covers Upon indication that insulating value is suspect
Rubber insulating blankets Before first issue and every 12 months thereafter*
Rubber insulating gloves Before first issue and every 6 months thereafter*
Rubber insulating sleeves Before first issue and every 12 months thereafter*

*If the insulating equipment has been electrically tested but not issued for service, it may not be placed into service unless it has been tested within the previous twelve months.

Note: ASTM F496-91 Section 7.3 permits gloves that are used in industries such as telecommunications, where the gloves are used as protection against unintentional contact, to be retested at up to nine-month intervals.
