Document EN 1149-5:2018 Protective clothing - Electrostatic properties - Part 5: Material performance and design requirements is a normative document that specifies the material and construction requirements for electrostatic dissipative protective clothing. It is a harmonized standard since March 5, 2021, as stated in the Official Journal of the European Union OJ L 077 - March 5, 2021.
The presumption of conformity with the essential health and safety requirements set out in Union harmonization legislation for the previous version of the standard:
- EN 1149-5:2008
expires on September 5, 2022.
EN 1149-5:2018 specifies the material and construction requirements for protective clothing with electrostatic dissipative properties. This includes hoods and caps used as part of a uniform earthing system to prevent incendiary discharges with a minimum ignition energy of 0.016 mJ or higher.
In the context of EN 1149-5:2018, a uniform earthing system refers to connecting personnel and other conductive elements to the earth through a resistance of less than 108 Ω.
The material and construction requirements do not cover additional equipment, such as breathing apparatus, that may come into contact with the protective clothing. If such equipment requires grounding, other requirements outside the scope of EN 1149-5:2018 may be necessary.
The standard does not include static dissipative protective gloves or footwear, as they are separate components and not integral parts of the clothing.
It is important to note that the material and construction requirements may not provide sufficient protection in oxygen-enriched flammable atmospheres. Additional information on this topic can be found in CEN/CLC/TR 16832:2015.
The document does not cover protection against voltages in supply networks.
