The EN ISO 11611 standard sets out the basic safety requirements and testing methods for protective clothing used in welding and similar processes. This clothing is designed to shield the wearer from hazards such as small splashes of molten metal, brief exposure to flames or electric arcs during welding, and the risk of electric shock from inadvertent contact with conductors carrying up to 100 V. It's worth noting that the clothing's protective properties may be compromised by sweat, dirt, or other contaminants, which can reduce its ability to guard against short-term interactions with live electrical conductors at this voltage.
