The EN 4199 standard series describes bonding straps used for aircraft. The new edition of Part 003 defines the characteristics of bonding straps with flat braided copper conductors, tin or nickel plated, and terminal lugs, tin or nickel plated, crimped on both ends, for use on aircraft. This standard shall be used together with EN 4199-001.
