Welcome to our impact testing episode of The Lab!
I’m your host Amanda and today I’ll be showing you exactly how Superior Glove tests our impact-resistant gloves to be sure we’re giving you the best information possible to protect your hands.
ANSI/ISEA 138 is the new impact standard that was recently released. Here’s a quick overview of the new standard and what’s changed:
- ANSI/ISEA 138 is unlike any other standard the industrial glove market has ever seen
- Results must come from a third party using an accredited lab, not from the manufacturers
- Standard offers three levels of classification with Level 1 indicating the lowest level of impact protection and Level 3 the highest
- Both the knuckles and fingers are tested and the overall rating of the glove is the lower of the two
When it comes to testing impact-resistant gloves, there is one very important step before turning on any machine or pulling any levers. Find someone whose hand fits the glove perfectly and have them clutch a rod of defined diameter, then note the points on the outside of the glove where their knuckles are – these are the points that will be tested.
At Superior Glove we use a Cadex Impact Tester. The way it works is that a two-and-a-half kilogram weight is attached to the carriage. The carriage is then lifted up to a pre-determined height and the weight is released. The weight drops onto the pre-measured impact points on the glove.
The force transmitted by the impact is recorded by the computer. The impact is recorded in kilonewtons (kN), measuring the force of the impact. The lower the kilonewtons, the lower the force transmitted through the glove to your hand on impact and the better those gloves will protect your hands.
Let’s look at some examples!
Clutch Gear Impact Protection Mechanics Gloves Lined with Punkban (MXVSBPB)
The first glove we’re going to test is our MXVSBPB. This glove is designed to provide a base level of protection and allows about 6.6 kN of force to transfer through to the fingers and knuckles.
Endura Impact Resistant Goatskin Driver Gloves with Oilbloc (378GKVSB)
The next glove we’re going to test is our 378GKVSB, which is a great choice for those exposed to average impact hazards. It typically allows about 5.9 kN of force through to the fingers and knuckles.
Finally, for the highest level of impact protection, we’re going to test our MXD3O. These gloves only allow about 3.9 kN of force to pass through to your fingers and knuckles and are the best choice for those facing serious impact hazards.
