SPECIFICATION FOR RUBBER MATS FOR ELECTRICAL PURPOSE
(Bureau if Indian Standard : 5424 - 1969)
The Electrical Resistance Rubber Mats are used as a floor covering, around electrical apparatus, whose voltage rating is 3000 volts. It is not intended to imply that rubber mats should afford the sole means of protection for those working on electrical circuits. Wherever possible, further adequate precautions should be taken against the risk of shock and short circuit.
| Design of electrical Resistance Rubber Mat |
The upper surface of the rubber mat, Resistance Rubber Mat will Rubber Chequered Patteren.
The lower surface of the rubber mat, may have plain smooth finish |
| Colour if the Electrical Rubber Mat |
Available in Black, Red and other colour as per customer choice |
| Dimension of Electrical Rubber Mat | Standard Size 2 Meter Long x 1 Meter Width 6 Feet Long x 3 Feet Width |
| Special Sizes 1 Meter Width x in Long Length for Chequred and Plain Rubber Mat |
|
| Thickness of the Electrical Mat | From 6.0 mm to 75.0 mm any thickness |
| Workmanship and Finish | The material will be free from blisters, pin holes, cracks, embedded foreign matters, and other defects, which may impair its serviceability, when visually examined |
| Voltage Test | The mat will withstand 15000 volts for one minute when tested. The mat will neither puncture, nor become appreciably warm at any spot or show any other evidence of weakness. The leakage current will not exceed 10 A/ sq. mtr, for any position of electrodes. |
| Break down strength | The mat will not fail at less than 40 KV, when tested in air between electrodes |
| Tensile Strength at break | 50 kg/ sq. cm minimum |
| Elongation at break | 250% minimum |
| Compression Set | will not exceed 10% |
| Water absorption | will not absorb more than 4 mg/sq. cm |
