Deltflam and Dynaflam Safety Specifications

Safety requirements for belts to be used above ground

The following are the most commonly used safety standards for above ground applications:

Safety level according to DIN norm	DIN norm number	Required Properties	Norms which describe how the test is to be conducted	General description of the test ISO/DIN/NF
E	DIN 22102	Antistatic	ISO 284 DIN 22104 NF 47109	Measure of the electrical conductivity between two electrodes. The resistance has to be lower than 300 Megohm
K	DIN 22102	Antistatic	ISO 284 DIN 22104 NF 47109	Measure of the electrical conductivity between two electrodes. The resistance has to be lower than 300 Megohm
K	DIN 22102	Flame resistance test with the outer covers	ISO 340 DIN 22103 NF 47108	The belt is tested with its outer covers. Six samples are put in contact with a flame for 45 seconds. The fire has to die out within 15 seconds on each sample following the withdrawal of the flame. The total duration for the six samples together has to be less than 45 seconds
S	DIN 22102	Antistatic	ISO 284 DIN 22104 NF 47109	Measure of the electrical conductivity between two electrodes. The resistance has to be lower than 300 Megohm
S	DIN 22102	Flame resistance test done with and without the outer covers	ISO 340 DIN 22103 NF 47108	The belt is tested with and without its outer covers. Six samples are put in contact with a flame for 45 seconds. The fire has to die out within 15 seconds on each sample following the withdrawal of the flame. The total duration for the six samples together has to be less than 45 seconds
vt	DIN 22109 Part 4	Antistatic	ISO 284 DIN 22104 NF 47109	Measure of the electrical conductivity between two electrodes. The resistance has to be lower than 300 Megohm
vt	DIN 22109 Part 4	Self- extinguishing	DIN 22118	Flame resistance test in a miniature gallery. One end of a 1200 mm sample is set alight. When the fire dies down the length of the belt that was not burnt is measured. The remaining length for a "solid-woven" belt, for example, has to be greater then 600mm. For a plied belt the length left intact has to be greater than 400mm
Safety level "E": All Delta and DYNA abrasion resistant belts are antistatic and therefore comply with the "E" safety level.

Special cases:

Safety belts for underground mines

These belts have to comply with safety regulations in practice in the country in which they are to be used. If you want to know more about these belts, please refer to the special brochure for your country.

Safety belts for the food industry

Belts to be used in the food industry have to be compatible with food products, have to be white and in some cases to be antistatic and flame resistant. Such safety belts used in the transportation of food products are described in a special brochure on belts for the food industry.
