21、laws, standards and internal rules dealing with the matters coming within the scope of EN 50110 and these practices have been taken as a basis for this work. EN 50110 consists of two parts: Part 1 of EN 50110 contains minimum requirements valid for all CENELEC countries and some additional informati
22、ve annexes dealing with safe working on, with, or near electrical installations; Part 2 of EN 50110 consists of a set of normative annexes (one per country) which either specify the present safety requirements or give the national supplements to these minimum requirements. This concept is still beli
23、eved to be a decisive step to the gradual alignment in Europe of the safety levels associated with the operation of, work activity on, with, or near electrical installations. This document acknowledges the present different national requirements for safety. The intention is, over the course of time,
24、 to create a common level of safety. Even the best rules and procedures are of no value unless all persons working on, with, or near electrical installations are thoroughly conversant with them and with all legal requirements and comply strictly with them. BS EN 50110-1:2013EN 50110-1:2013 6 1 Scope
25、 This European Standard is applicable to all operation of and work activity on, with, or near electrical installations. These are electrical installations operating at voltage levels from and including extra-low voltage up to and including high voltage. This latter term includes those levels referre
26、d to as medium and extra-high voltage. These electrical installations are designed for the generation, transmission, conversion, distribution and use of electrical power. Some of these electrical installations are permanent and fixed, such as a distribution installation in a factory or office comple
27、x, others are temporary, such as on construction sites and others are mobile or capable of being moved either whilst energised or whilst not energised nor charged. Examples are electrically driven excavating machines in quarries or open-cast coal sites. This European Standard sets out the requiremen
28、ts for the safe operation of and work activity on, with, or near these electrical installations. The requirements apply to all operational, working and maintenance procedures. They apply to all non-electrical work activities such as building work near to overhead lines or underground cables as well
29、as electrical work activities, when there is a risk of electrical danger. This European Standard does not apply to ordinary persons when using installations and equipment, provided that the installations and equipment comply with relevant standards and are designed and installed for use by ordinary
30、persons. This European Standard has not been developed specifically to apply to the electrical installations listed below. However, if there are no other rules or procedures, the principles of this European Standard could be applied to them on any aircraft and hovercraft moving under its own power,
31、(these are subject to International Aviation laws which take precedence over national laws in these situations); on any sea going ship moving under its own power, or under the direction of the master, (these are subject to International Marine laws which take precedence over national laws in these s
32、ituations); electronic telecommunications and information systems; electronic instrumentation, control and automation systems; at coal or other mines; on off-shore installations subject to International Marine laws; on vehicles; on electric traction systems; on experimental electrical research work.
