EN 388 is a European Standard. Cut Level is determined by the number of cycles it takes a spinning circular blade, that is pulled across the material under a constant weight of 500 grams, to cut the fabric. As the number of cycles increase, so does the glove's ratings.
EN 407 is a general European standard designed to be used for any glove that is to be sold as providing protection against thermal hazards. All six tests are graded on a scale from 0 to 4, with 0 signifying that the glove failed the test, and 4 demonstrating it has achieved the maximum resistance in that specific area.
The EN 511 standard specifies the requirements and performance levels of work gloves against cold as low as -50°C. Protective devices against: convective cold, contact cold and water penetration. Convective and contact tests are graded on a scale from 0 to 4, with 0 signifying that the glove failed the test, and 4 demonstrating it has achieved the maximum resistance in that specific area. Water permeation is graded on a scale of 0 to 1 where 0 indicates “water penetration after 30 minutes” and 1 indicates “no water penetration after 30 minutes”.
