EN 388 CUT VS. ANSI

Legend:
N = g × 0.00981
force = mass × 0.00981

EN 388: measures
FORCE using Newton

ANSI/ISEA 105: measures
MASS using grams

The new global cut standards

EN 388:2016 (ISO 13997)

15 Newton = 1529 Grams to Cut

Medium Cut Hazards

  • Uses Coup Test as well as the TDM-100 cut machine (ISO 13997) to test cut level to accommodate limitations (dulling of the blade) in the Coup Test when testing strong cut-resistant fabrics
  • Coup Test measures number of cycles required to cut through the glove
    > Reporting is 1 – 5
  • TDM-100 measures NEWTON of force up to 30+N
    > Reporting is A – F

ANSI/ISEA 105-16 (ASTM F2992-15)

15 Newton = 1529 Grams to Cut

Medium Cut Hazards

  • Uses TDM-100 cut machine to test cut level
  • Measures in GRAMS of force up to 6000g (previously 3500 g)
  • Reporting is in 9 levels instead of previously 5 to accommodate stronger cut-protective fibres
  • Tests under the new standard have an “A” before the cut level

Cold protection

Cold protection A

Resistance to convective cold (performance level 0 to 4)

This is based on the thermal insulation oproperties of the glove which are obtained by measuring the transfer of cold via convection

Cold protection B

Resistance to contact cold (performance level 0 to 4)

This is based on the thermal resistance of the globe material when exposed to contact with a cold object

Cold protection C

Penetration by water (0 or 1)

0 = water penetration
1 = no water penetration

Heat protection

Note: S = seconds g = gram

Heat protection

Bacteriostatic

  • Our Kyorene® fibres have inherent bacteriostatic properties. Kyorene® Graphene oxide is polymerized inside the fibre, acting as a primary inhibitor for the growth of new bacteria.
  • Some other products on the market use a chemical treatment such as silver. These treatments, while effective at the beginning, can be washed out and become ineffective. After 50 wash cycles, Kyorene® keeps its bacteriostatic properties intact.

Heat dissipation

Thermal transmittance is measured using test method GB/T 11048-2008 Method B. Thermal transmittance (Watts per square meter Kelvin) is defined as the rate of transfer of heat through one square meter of a structure divided by the temperature across the structure. The higher the value, the more transmittance or heat dissipation is occurring. Testing according to this well established method for textiles has shown that the addition of Kyorene® to the fabric has 1.5 times more thermal transmittance than the fabric without. In plain English, the data shows Kyorene® and Kyorene® Pro to provide for a cooler and less sweaty hand inside a glove.
