DuPont™ Arc-Man® located in Geneva
This equipment developed by DuPont measures the ATPV value of protective fabrics
and garments in simulated open electric arc incidents. It exposes the materials to energy levels of up to 70 cal/cm² (for information, continuous exposure to 1.2 cal/cm² may be enough to cause a 2nd degree burn on human skin generated by an open arc).
Incident energy is calculated based on several parameters influencing an electric arc, such as current, duration of the arc, electrode material, the gap between the electrodes and the distance of the tested fabrics or garments to the arc. Arc-Man® performs the tests according to the current valid standard parameters in IEC 61482-1.
Arc-Man® can test fabrics on panels, measuring the ATPV value of the fabric system (in cal/cm²) so that it can be compared with the incident energy calculated in the end user’s risk assessment. Arc-Man® can also perform complementary garment tests on a torso to show the effect of a garment’s design and integrity of manufacture, allowing an assessment of the garment’s behaviour (e.g. of the closure system, the pockets, etc.).
The box test according to IEC 61482-1-2 (equivalent to EN 61482-1-2) can also be performed on the DuPont™ Arc-Man® testing facility.
