440 V AC is an optional requirement from the helmet norm EN397. It is intended to provide protection to the wearer against short-term, accidental contact with live electrical conductors. The leakage test is performed in 3 diﬀerent conditions. The voltage used for this test is 1200 V AC. 1000 V AC from EN 50365. Electrically insulating helmets
12/1/2016, · Method of Testing ,Electrical, Resistance. With ,helmet, inverted immerse in solution of 6g/l water, and filled up to 12mm and let it stay for 18-24 hours at room temperature. Subject it to alternating ,voltage, of 2000V(50Hz) slowly immersing conducting rods. Method of Testing Water Absorption. Immerse the ,helmet, for 24 hours in water.

Z89.1-1997 also changed the alpha designations for the classes of ,electrical, performance. Class G (General) ,Helmets,: This is equivalent to the old Class A. Class G ,helmets, are proof-tested at 2,200 volts. Class E (,Electrical,) ,Helmets,: This is equivalent to the old Class B. Class E ,helmets, are proof-tested at 20,000 volts.
The flame resistance test applies to special application racing helmets only. The test is conducted using a propane flame of approximately 790 degrees centigrade. The flame is applied to the shell, trim, chin strap and face shield for a specified number of seconds, and any resulting fire must self extinguish within a specified time after flame removal.
Helmet safety, is controlled through equestrian standards and certifications. Standards are lists of tests and checks created by a group of biomechanical engineers with pass or fail criteria. All riding ,helmet, manufacturers have to produce ,helmets, to meet one of three international equestrian ,safety, standards or marks: PAS015:2011, VG1 01.040 2014-12 and ASTM F1163:2015.
