UNE-EN 1149-5:2018

This European Standard specifies material and design requirements for electrostatic dissipative protective clothing, including hoods and caps, used as part of a total earthed system, to avoid incendiary discharges. In the context of this European Standard, a total earthed system is one in which personnel and other conductors are connected to earth via a resistance of less than 108 ©.

The requirements of this European Standard apply to electrostatic dissipative protective clothing intended to be worn in potentially explosive atmospheres where the minimum ignition energy is not less than 0,016 mJ.

The material and design requirements do not presume adequate earthing of additional equipment worn or carried in contact with clothing, e.g. breathing apparatus, etc. If such additional equipment is required to be earthed, other requirements beyond the scope of this European Standard may be necessary.

The scope of this standard does not include electrostatic dissipative protective gloves or footwear that are separate and not integral parts of garments.

The material and design requirements may not be sufficient in oxygen enriched flammable atmospheres. This European Standard is not applicable for protection against mains voltages.
