For these reasons, this European Standard, in several instances, leaves a choice to the contracting parties between two alternatives. These alternatives consist either in the provision
25、of operating rules, regulations and procedures, or in the application of technical measures such as mechanical or electrical interlocking devices. A list of the cases for which the contracting parties (e.g. user and manufacturer) should reach agreement before signing the contract is included in anne
26、x B. 1Scope This European Standard offers a set of rules that are applied in the design and manufacture of electrical installations and equipment to be used on rolling stock so as to protect the persons from electric shocks. The methods used to satisfy the rules may differ, in accordance with the pr
27、ocedures and practices of the operating organization. This European Standard is applicable to vehicles of rail transport systems, road vehicles powered by an external supply (e.g. trolley buses), magnetic levitated vehicles and to the electrical equipment installed in these vehicles. This European S
