FIELD: mining industry. SUBSTANCE: in compliance with process sample is dropped from determined height on to rusted plate. Its surface is moistened and area of trace formed as a result of collision with sample is measured. Area of trace is used to judge about spark safety. EFFECT: ensured authenticity of testing.
