EUROPEAN STANDARDS FOR HAND PROTECTION - PROTECTIVE GLOVES: GENERAL REQUIREMENTS
EN 21420 General requirements and test methods - Protective gloves
Protection for: light and superficial mechanical work, handling of thinly diluted detergent solutions, handling of small components that are slightly hot (max 50°C), winter outdoor activity with medium temperatures (max 0°C).
EN 420 2003 + A1:2009
This standard defines the requirements for gloves in terms of design, construction, cleaning, instructions, electrostatic properties, sizing, dexterity, water vapor transmission and absorption with markings and information.
PROTECTIVE GLOVES AGAINST MECHANICAL RISKS - EN 388
In recent years, changes in the manufacturing process of protective gloves have meant that the well-proven method of hand protection testing (EN388:2003), and in particular the test to evaluate cut protection, is no longer suitable. While the old EN388:2003 system with the 1 to 5 numbering system was easily understood, the development of new cut resistant materials combined with a push from industry to provide the highest level of protection possible has made it necessary to review the method for test hand protection.
EN388:2016+A1:2018 requires updating the standard and, in doing so, 2 tests have been revised (abrasion and cut) and 2 new tests have been included (TDM cut resistance and impact resistance). The EN388:2003 standards specify physical and mechanical aggression caused by abrasion, blade cutting, tearing and puncturing. EN388:2016+A1:2018 updates the existing standard with this new test method for abrasion, TDM shear and impact resistance. EN ISO 13997:1999 (TDM test) records cut results as a Newton value - the force of the blade on the glove material required to cut 20mm material. Results are represented on an A-F scale.

EN 16350:2014 Protective gloves: electrostatic properties
This European standard specifies a test method for properties electrostatics of the gloves. The test improves on EN1149 by requiring a vertical resistance of less than 1.0x108 ohm. Gloves tested to EN16350:2014 can be used in areas where there may be an increased risk of explosion, such as in a refinery.
CE Foodsafe (MOCA)
The Framework Regulation (EC) 1935/2004 provides that materials or objects intended to come into contact with food must not:
- constitute a danger to human health;
- lead to an unacceptable change in the composition of food products;
- lead to a deterioration of their organoleptic characteristics.
All these materials or objects must be marked with the specific symbol which certifies their suitability for contact with food.
IEC 61340-5-1:2016
Protection of electronic devices from electrostatic phenomena:
general requirements
Questa norma europea specifica un metodo di prova per le proprietà elettrostatiche dei guanti. Il test migliora la EN1149 in quanto richiede una resistenza verticale inferiore a 1,0x108 ohm. I guanti testati secondo la norma EN16350:2014 possono essere utilizzati in aree in cui potrebbe esserci un maggiore rischio di esplosione, come in una raffineria.
EN 511:206 Anti-cold gloves
The European standard specifies the requirements and test methods for gloves that protect from cold up to -50°C. This type of cold can be due to climatic conditions or industrial activity. REQUIREMENTS:
