EN 61111 Working Under Voltage - Electrical Insulation Coating

The EN 61111 standard, a European standard, is applied to electrical insulation felt made of elastomer for use as a floor covering for electrical protection of workers in electrical installations. In the last update of this standard, significant technical changes were introduced compared to the previous standard. For example,

• Requirements and test provisions are generally reviewed.
• The test procedure for slip resistance has been changed.
• Elements for the assessment of defects have been designed and the general application of the IEC 61318 standard has been adopted.
• Existing annexes have been revised.
• Annexes (Annex D and Annex F) that are not valid according to the IEC 61318 standard have been deleted.
• A new annex (Annex F) has arrived on the classification of defects.

In the EN 61111 standard, the physical requirements are organized under the following headings:

• Composition
• Figure
• Dimensions and tolerances
• Workmanship and finish
• Mechanical, climatic and environmental requirements
• Dielectric requirements
• Marking
• Packaging
• Instructions for use

The tests in the EN 61111 standard are organized under the following headings:

• General
• Visual inspection and measurements (overall, classification, composition, dimensions, workmanship and finish, thickness)
• Marking (visual inspection and measurement, durability of marking)
• Packaging and usage instructions
• Mechanical tests (general, mechanical puncture resistance, slip resistance test)
• Dielectric tests (general, electrodes, test equipment, electrical test procedure)
• Aging tests
• Thermal tests (flame retardant test, low-temperature folding test - extremely low-temperature folding test for category C coatings only, excluding coating in category C)
• acid resistance
• oil resistance

The product covered by this standard has an environmental impact at some or all stages of its life cycle. These impacts range from minor to significant, can be short-term or long-term, and can occur at a global, regional, or local level. Aside from a disposal statement included in the instructions for use, this standard does not contain requirements for manufacturers, testing provisions, or recommendations for environmental remediation for product users. However, everyone involved in the design, manufacture, packaging, distribution, use, maintenance, repair, reuse, recovery, and disposal of the product must consider environmental considerations.
