EN 1149-5 

Electrostatically dissipative protective clothing

DIN EN 1149-5 is a standard that deals with electrostatically dissipative protective clothing. Electrostatic charges can pose considerable risks in certain working environments, especially when they affect flammable atmospheres or sensitive electronic components. In order to minimise such risks, the standard DIN EN 1149-5 was developed to define requirements and test methods for protective clothing that is capable of safely dissipating electrostatic charges. 

This standard plays a crucial role in various industries, including the chemical and electronics industries, where protection against electrostatic discharge is of great importance. In this introduction, we will take a closer look at the key aspects of DIN EN 1149-5 and understand why this standard plays an important role in the field of occupational safety and personal protection.

Description 

Protective clothing against electrostatic charge according to EN 1149 protects against ignitable discharges. Attention! This standard does not apply to protection against live parts. 
The standard specifies the requirements for electrically conductive garments. According to the standard, the protective clothing is part of a fully earthed system (e.g. in combination with conductive footwear). It is intended to prevent sparking and thus also explosions. 
 
The standard is a series of standards and is structured as follows: 
  • EN 1149-1 Part 1: Test method for the measurement of surface resistance 
  • EN 1149-2 Part 2: Test method for measuring contact resistance 
  • EN 1149-3 Part 3: Test method for measurement of charge decay 
  • EN1149-4: Test method for the garment (under development) 
  • EN 1149-5 Part 5: Performance requirements for material and construction requirements.  
  • EN 1149-5 is usually tested in combination with EN 1149-3. 

According to EN 1149-5, what are the most important requirements for protective clothing? 

  • All garments without electrostatic dissipative properties underneath the protective clothing must always be completely covered.
  • The wearer of electrostatically dissipative protective clothing must be properly earthed (dissipation resistance < 108 ohms). 
  • All chargeable materials (e.g. metal buttons) must be covered to the outside. 
  • Individual garments must be combined with conductive equipment (e.g. conductive shoes).

Protective effect

Protective clothing that has been certified according to this standard protects wearers from electrostatic charge and thus from an ignitable discharge.

Areas of application

Areas of application are industries or professions in which there is a risk of explosion and thus a risk of fire. These include:

  • Energy supplier
  • Public utility
  • Electrical installation
  • Electrical trade
  • Electroplating
  • Hazardous goods transport
  • Chemical industry
  • Plant construction
  • Solar plants
  • Wind turbines
  • Combined and grid assemblers
  • Transport 
  • Oil and gas production
