Performances of Comasec gloves are assessed according to the European standards. They are symbolised by pictograms sometimes with figures representing their levels of performances. These standards are regularly updated, hereafter the lastest edition:
EN 420: 2003 General requirements for protective gloves

This pictogram indicates that the user has to consult the instructions for use.
EN420 lays out the general requirements of most types of protective gloves including:
- Ergonomy, construction (neutrality of pH, amount of dectectable CrVI and no allergenic incorporated substances), innocuousness and comfort (size), dexterity, water vapour transmission and absorption.
- If requested electrostatic properties must be measured according to the tests of the EN 1149-1-2 OR 3. Pictograms shall not be used and specific information on lab test conditions must be added.
- Indication of the levels of performances: 1 : minimum, 2 : good, 3 : very good, 4 and more : excellent, 0 : does not offer protection, X : performance not measured.
- Information on using instructions and levels of performance according to the standards described hereafter
Selection of the glove’s size according to the hand length and circumference.
| Glove´s size | 6 | 7 | 8 | 9 | 10 | 11 |
| Minimal length (mm) | 220 | 230 | 240 | 250 | 260 | 270 |
| Hand circonference (mm) | 152 | 178 | 203 | 229 | 254 | 279 |
| Hand length(mm) | 160 | 171 | 182 | 192 | 204 | 215 |
A glove for special applications may not conform to these values, in which case, these applications must be clearly explained in the instructions for use.
