Importance of IEC 61111:2009 for Electrical Insulation on Rubber Mats
Overview of IEC 61111:2009 IEC 61111:2009 is the international standard that specifies requirements and test methods for electrical insulating matting made of elastomer. It updates the original 1992 edition and 2002 amendment, ensuring live-working protection is assessed consistently across manufacturers and applications.
1. Key Requirements and Testing Procedures
Defines approved elastomer materials, minimum width, and thickness to guarantee uniform insulation under load.
Includes slip-resistance tests to verify stability in oily, wet, or contaminated environments.
Adopts defect evaluation criteria (per IEC 61318) to identify cuts, blisters or inclusions that could reduce dielectric strength.
2. Classes of Electrical Insulating Mats Table: Voltage classes, test voltages and dielectric performance
Class
Test Voltage
Working Voltage
Dielectric Strength
0
5 kV
1 000 V
10 kV
1
10 kV
7 500 V
20 kV
2
20 kV
17 000 V
30 kV
3
30 kV
26 500 V

36 000 V
50 kV
Selecting the correct class prevents mat breakdown during unexpected voltage surges and guarantees user safety.
3. Why Compliance Matters
Protection against electric shock
Certified mats form a non-conductive barrier, minimizing the chance of current passing through a worker’s body.
Legal and regulatory adherence
OSHA, HSE and many other authorities reference IEC 61111:2009. Non-compliant installations can incur fines, work stoppages or liability risk.
Durability and performance
Mats tested under this standard resist moisture, oils, ozone, and UV exposure—ensuring long-term insulation integrity.
4. Practical Considerations for Usage
Inspect mats daily for cuts, tears, hardening or embedded debris; retire any with visible damage.
Clean only with mild detergent and water; avoid solvents or abrasive cleaners that degrade elastomer.
Store rolled or flat in a dry area, shielded from direct sunlight, heat sources and sharp objects.
5. Holistic Safety System To maximize protection, pair IEC 61111:2009-compliant matting with:
Insulating gloves and sleeves rated to the same voltage class
Face shields or goggles to guard against arc-flash events
Lockout/tagout procedures and live-line tools for controlled maintenance
