197 DIN EN 16350:2014 Safety gloves – Electrostatic characteristics The new standard Choosing the right personal protective equipment (PPE) is particularly important in working environments that are hazardous or harbour health risks. For workplaces at risk of fire and explosive atmospheres, “EN 16350:2014 – Protective gloves – electrostatic properties” is the first European standard to prescribe the test conditions and minimum requirements for electrostatic properties of safety gloves. vertical resistance must be less than 1.0×108 Ω (Rv < 1.0×108 Ω). test atmosphere: ambient temperature of 23 ± 1 °C, relative humidity of 25 ± 5%. Important notice: Electrostatic discharge safety gloves are only effective if the wearer is grounded with resistance of less than 108 Ω. What should users take into account? EN 16350:2014 is the first standard to define a limit value for vertical resistance for protective gloves; this value was not included in DIN EN 1149. Users must therefore check the suitability of the protective gloves in line with EN 16350:2014. References to EN 1149 are no longer sufficient, as this standard only describes the testing procedure and does not specify a limit value.

The insulation protection class of the insulating personal protective equipment (PPE) is determined according to the nominal voltage of the plant, with both the maximum permissible nominal AC voltage (AC) and the nominal DC voltage (DC) being calculated. DIN EN 61482-1-2:2015-08 Live working - Protective clothing against the thermal hazards of an electric arc Part 1–2: Test methods – Method 2: Determining the arc protection class of the material and the clothing using a directed test arc (box test) Hands are at the greatest risk of burns from short circuit electric arcs when working on electrical equipment. Unfortunately, there is no recognised standard for safety gloves in Germany for testing the potential dangers of a short circuit electric arc. Therefore, safety gloves for protection against the thermal discharge of a short circuit electric arc are generally tested in accordance with EN 61482-1-2 and classified accordingly.

G2 offers the highest level of protection. GR: Partially coated safety gloves provide protection against dried spray coatings during follow-up work. G1: Fully coated safety gloves for handling ready-to-use crop protection products. G2: Fully coated safety gloves for use with concentrated crop protection products. DIN EN 60903 Class 0 R
