When I would get new gloves I would always roll up the cuffs to pressurize the hand and finger sections. Found one with the webbing between two fingers trashed once with that little test.
Haven't tried it with the low voltage gloves with the short cuffs though.
Don't know if people still do it or not, but I sure would.
It is an OSHA requirement that they are properly inspected before each use
1910.137 (b) "In-service care and use."
(b)(1) Electrical protective equipment shall be maintained in a safe, reliable condition.
(b)(2) The following specific requirements apply to insulating blankets, covers, line hose,
gloves, and sleeves made of rubber:
(b)(2)(i) Maximum use voltages shall conform to those listed in Table I-5.
(b)(2)(ii)
Insulating equipment shall be inspected for damage before each day's use and
immediately following any incident that can reasonably be suspected of having
caused damage. Insulating gloves shall be given an air test, along with the
inspection.
(b)(2)(iii) Insulating equipment with any of the following defects may not be used:
(b)(2)(iii)(A) A hole, tear, puncture, or cut;
(b)(2)(iii)(B) Ozone cutting or ozone checking (the cutting action produced by ozone on rubber
under mechanical stress into a series of interlacing cracks);
(b)(2)(iii)(C) An embedded foreign object;
(b)(2)(iii)(D) Any of the following texture changes: swelling, softening, hardening, or becoming
sticky or inelastic.
(b)(2)(iii)(E) Any other defect that damages the insulating properties.
(b)(2)(iv) Insulating equipment found to have other defects that might affect its insulating
properties shall be removed from service and returned for testing under
paragraphs (b)(2)(viii) and (b)(2)(ix) of this section.
(b)(2)(v) Insulating equipment shall be cleaned as needed to remove foreign substances.
(b)(2)(vi) Insulating equipment shall be stored in such a location and in such a manner as to
protect it from light, temperature extremes, excessive humidity, ozone, and other
injurious substances and conditions.
For the air test it is best to use a glove inflator because rolling them up does not check the cuff where for failures occur, the cuff is not protected by the leather outers.
Visually inspect each glove by gently stretching the rubber, working around the glove. Check for foreign material, cuts, scrapes, scratches, snags, holes, or discoloration. Very few failures will be found from an air test alone.
Most people don't know what ozone damage looks like, and it is the most common failure of gloves, it looks like dry rot when you pull on the rubber, you would only see this by doing the inspection properly.
