EN1149 - Antistatic workwear
CE certified workwear for protection against electric arcs
Protective clothing certified according to EN 1149-5 provides the wearer with electrostatic dissipative clothing with reduced risk of sparking. The garment should be used as part of a total earthed system to avoid combustible discharges.
The article covers all other materials that do not provide protection against static electricity.
Thin attachments such as labels, reflectors and the like, must be attached permanently.
Conductive parts, such as buttons and zips, are permitted provided that they are covered completely by the protective material against discharges of electrostatic energy.
EN1149-1 measure of surface resistivity – treated material
EN1149-3 measure of charge decay – core conductor
of explosion e.g. in refineries.
Fabric Demands:than 10mm.
An electrostatic dissipative material shall meet at least one of the following:
• T50 < 4s ore s > 0,2, En 1149-3
• Surface resistance = 2,5 ×109 ohm, En 1149-1
• The distance between the conductive threads contained in the material must not be greater
• Thin additions, such as labels and reflectors, must be permanently sewn on. No loose-hanging parts are permitted.
• Elements that conduct electricity (zips, buttons, etc) are permitted if they are completely
When using these garments, the wearer must be properly earthed. The resistance between
Electrostatic dissipative protective clothing shall not be opened or removed in flammable or explosive atmospheres or while handling flammable or explosive substances. Wear and tear,laundering and any contamination can affect the electrostatic dissipative performance of the electrostatic dissipative protective clothing. The garment shall permanently cover all non-compliant material during normal use. The garment should only be used in rooms with increased oxygen content following approval from the relevant safety engineer. Do not make alterations to the garments. Minor embroidery or transfer is permitted on fabric certified to En 531/En ISO 11612 and shall be permanently attached to the garment so that separation is avoided.
