legible for at least four years from delivery subject to weather, marine atmosphere and

handling. Such marking materials shall not be injurious to the items being marked and in

particular, the marking ink used should be low-chloride or chloride free and shall contain

no metal or metal salts such as zinc, lead, copper or tin, which could be harmful on
