• AC-Proof Voltage: The AC-proof voltage of these mats is 5 kV.
• Thickness: The standard thickness of Class 0 IEC 61111 mats ranges from 2 mm to 6 mm.

Class 1 IEC 61111 Electrical Safety Matting Guide

• Working Voltage: These dielectric rubber matting are used for working voltages up to 7.5 kV.
• Dielectric Strength: They do not have a dielectric breakdown up to voltages of 20 kV.
• AC-Proof Voltage: The electrical rubber matting safety guide suggests that its AC-proof voltage is 10 kV.
• Thickness: The standard thickness of class 1 mats is the same as that of Class 0 insulating mats.

Class 2 IEC 61111 Electrical Safety Matting Guide

• Working Voltage: As per the electrical safety matting guide, these mats are applicable for working voltages of 17 kV.
• Dielectric Strength: The dielectric strength of these mats is 30 kV.
• AC-Proof Voltage: This electrical rubber matting safety class has an AC-proof voltage value of 20 kV.
• Thickness: These insulating mats have thicknesses between 3 mm and 8 mm.

Class 3 IEC 61111 Electrical Safety Matting Guide

• Working Voltage: Class 3 dielectric rubber matting of the IEC 61111 standard is applicable for working voltages up to 26.5 kV.
• Dielectric Strength: This electrical rubber matting safety class has a specification of 40 kV dielectric strength.
• AC-Proof Voltage: These insulating mats have 30 kV AC-proof voltage.
• Thickness: The Class 3 IEC 61111 mats have thicknesses that range from 4 mm to 11 mm.

Class 4 IEC 61111 Electrical Safety Matting Guide

• Working Voltage: The class 4 of IEC 61111 electrical rubber matting safety standard is suitable for working voltages up to 36 kV.
• Dielectric Strength: This electrical rubber matting safety class has a dielectric strength of 50 kV.
• AC-Proof Voltage: The AC-proof voltage of these insulating mats is 40 kV.
• Thickness: The Class 4 mats are thickest. Their thicknesses range from 5 mm to 14 mm.

Other Features

• As per the electrical rubber matting safety guide, all the classes of IEC 61111:2009 standard have good mechanical strength. Besides, they are resistant to UV rays, ozone, puncture, mild to moderate acid, oil, and physical stress.
• However, they also have good resistance against a wide array of temperatures. They do not disintegrate in temperatures ranging from -25 degrees to 55 degrees centigrade.
• All the classes of IEC 61111 insulating mats come with anti-skid properties. They have a ribbed surface texture, which increases the friction of the feet to The dielectric rubber matting uses include reducing physical accidents such as slipping and falling.
• Suppliers might also provide you with the option of customization. As a result, you can custom-make your IEC 61111 mats of any class as per your requirements (according to your application dimensions).

To sum up, 

The IEC 61111:2009 standard, among all the rubber mat insulation standards, is quite renowned in the international market. Starting from power industries to manufacturing units, different classes of mats are used. Each class has a different set of specifications. Hence, make sure to be thorough with each of them before purchasing!

How about some interesting FAQs?

What are the disadvantages of getting a mat at a cheap rubber mat insulation price?

Ans: Cheap safety rubber matting electrical is usually from a non-branded source. They may lack certification due to a lack of proper quality control. Besides, they might not be compliant with the industrial safety standards and regulations. These factors make them unreliable as protective equipment.

How does an anti-slip electrical mat reduce physical accidents?

Ans: An electrical switchboard rubber mat may come with a corrugated surface. The corrugated surface enhances the grip of the mat to the ground. The increased traction reduces the chances of slipping and falling. As a result, workers who are moving are not prone to getting injured due to physical accidents.

Where are high voltage insulating mats installed?

Ans: Dielectric rubber matting uses include installation in high-voltage risk areas of the industries. They are common in major industries, including the power, manufacturing, automotive, and others. However, people install them near electrical panels, transformers, generators, machines, switchgears, and others.
