EN388:2016 Protective gloves against mechanical risks.
The EN388: 2003 standard is renamed EN388: 2016, the year of its revision. The reason for the modification is given by the discrepancies in the results between laboratories in the knife cut test, COUP TEST. Materials with high levels of cut produce a dulling effect on the circular blades, which undermines the result.

The new regulation was published in November 2016 and the previous one is from the year 2003. During these 13 years, there has been a great innovation in the materials for the manufacture of cutting gloves, they have forced to introduce changes in the tests to be able to measure with more rigorous levels of protection.

The EN374: 2003 standard is renamed ENISO374: 2016. The purpose of this standard is to classify gloves according to their behavior when exposed to chemical substances.

They are divided into the following parts:
EN ISO 374-1:2016 - Terminology and performance requirements for chemical risks.
EN 374-2:2014 - Determination of resistance to penetration.
EN 16523-1:2015 + A1:2018 - Permeation by liquid chemicals under continuous contact conditions.
EN ISO 374-4:2019 - Determination of resistance to chemical degradation.
EN ISO 374-5:2016 - Terminology and requirements demanded for risks of microorganisms.

Gloves classification according to ENISO374-1: 2016

Gloves are divided into three types:

Step time ≥ 30 min for at least 6 products

pictograma 374 tipo b TYPE B

Step time ≥ 30 min for at least 3 products

pictograma 374 tipo c TYPE C

Step time ≥ 10 min for at least 1 products

Gloves classification according to EN374-2:2014
It is the advance of chemical products through the material, seams of the glove at a non-molecular level. Air leak test: the glove is inflated with air and immersed in water. The appearance of air bubbles is controlled within 30 '. Water leak test: the glove is filled with water and the appearance of water droplets is controlled. If these tests are positive, the pictogram will be put on.

Gloves classification according to EN374-4: 2013
Detriment to some of the glove's properties due to contact with a chemical. Eg: discoloration, hardening, softening, etc.Permeation test EN 16523-1. It is the advancement of chemicals at the molecular level. The resistance of the glove material to permeation by a chemical is determined by measuring the time it passes through the material.

Modification of the ENISO374-5: 2016 standard
When the glove passes the test described for virus protection, the word “virus” will appear under the pictogram. If nothing appeared, protection would only be assured against bacteria.

VIRUS

Minimum requirements for workers in contact with pesticides.

Chemical protection all over the hand.
Relatively low potential risk.
Handling of diluted pesticides.
No mechanical hazards.
Disposable: minimum length 240 mm.

Chemical protection all over the hand. Increased potential risk
More protection than the G1.
Handling of concentrated or diluted pesticides.
Minimum length 290 mm.
Minimum mechanical protection: abrasion - level 2, cutting - level 1 or letter A and perforation - level 1.

Partial hand protection (fingers and palm):
Minimum mechanical protection for handling tasks: abrasion-level 2, cutting – level 1 or A, tearing – level 1 and perforation – level 1.
For users in contact with partially dried or dried pesticide residues existing on the plant after applying the pesticide.
They cannot be used to replace the G1 or G2 that protect the whole hand.
A breathable material on the back of the glove enhances comfort.
