It is also important for the protection of parts and equipment due to controlled dissipation. The first aspect is covered by the requirement for antistatic footwear. Product protection also requires the ESD capability by safety shoes. The defined ESD range simply sets limits to the anti-static range of the safety shoe standard EN ISO 20345. Shoes are designated as ESD shoes if the electrical resistance of the person-shoe-floor system as defined in EN 61340-5-1 is less than 3.5 x 107 0 i.e. 35 MO. Here the lower limit of the electrical resistance is 0.1 MO and the upper limit is 35 MO (3.5 x 107 0). An ESD-capable shoe is thus always also an anti-static shoe. Warning: ESD shoes are unsuitable for use by electricians and for working on live electrical equipment. Resistance ranges to EN ISO 20345 / EN 61340 Electrical resistance ofa shoe 1 x 105 0 (0.1 MO) 3.5 x 107 0 (35 MO) 3.5 x 108 O (100 MO) 1 x 109 O (1000 MO) conductive Anti-static to EN ISO 20345 Electrostatically conductive to EN 61340-4-3 ESD to DIN EN 61340-5-1 insulating Sole types essentially single-layer (mono) and double-layer (duo) soles. The latter has the great advantage that it allows the use of two different materials with different properties. For instance the sole tread may be of rubber but the intermediate sole of polyurethane. The sole thus combines the advantages of both materials: The excellent heat resistance of rubber, and the comfortable shock absorption characteristics of polyurethane. The special advantage of the single-layer sole is that a single material with a lower density can be sprayed on. This creates a lightweight sole which can easily adapt to the floor characteristics. Rubber Extremely hard-wearing, heat resistant for short periods up to 300°C; good resistance to cuts and abrasion. Resistant to fuel, oil, microbes and a wide variety of chemicals. Heavier than PU and TPU and also somewhat less flexible when cold. Nitrile rubber (Perbunan) Very hard-wearing. Heat resistant up to 220°C. Very good non-slip characteristics and excellent resistance to acids and alkalis. Polyurethane (PU) Heat resistant up to 130°C and flexible in cold down to -30°C. Resistant to oil and fuel, a wide variety of chemicals, and microbes. Lighter than rubber soles. Good shock absorption characteristics and pleasant to wear. Thermoplastic polyurethane (TPU) Similar to PU soles, but overall significantly better performance. Less abrasion means the soles last longer, and also increases the non-slip properties. In addition they offer even greater flexibility and optimised resistance to cold. 321
