General 1 Scope This standard is applicable to aerial devices (mobile elevating work platforms MEWP), with or without the possibility of an additional jib, as a minimum with an insulating upper boom (
41、extending structure), used for live working on the nominal voltage, which is between 1 kV r.m.s. and 800 kV r.m.s., at power frequency. The application of some parts of this standard to d.c. systems is still under consideration. This standard specifies: the specialized technical characteristics, tes
42、ts and checks of the insulating parts (boom, extending structure, transmission of controls along the boom, work platform, bucket, accessories, jibs, etc.) required for live working; the technical characteristics, tests and checks of conducting parts, the conductive properties which are essential for
43、 positioning near to, or at, the potential of the live element (part) to be worked on; the special characteristics which are not necessarily subjected to test, but which are fundamental for ensuring the safety and precision essential to safe working on live parts. Excluded from this standard, but to
44、 be observed: specifications applicable to all kinds of aerial devices (mobile elevated work platforms) which are covered by applicable International Standards or national regulations, for example design, calculations, stability requirements, roadway code, employment regulations, etc.; specification
45、s for those parts of the aerial device (carrier, etc.) not specific to live working; specifications for personnel electrostatic shielding equipment (the user should provide adequate shielding equipment in accordance with national regulations). 2 Definitions 2.1 Definitions according to IEV Flashover
46、 An arc by-passing an insulating body (IEV 121-03-14). Puncture A disruptive breakdown through a solid insulant (IEV 121-03-13). Sparkover A disruptive discharge: passage of an arc following dielectric breakdown. NOTEThe term “ sparkover” is used when a disruptive discharge occurs in a gaseous or li
47、quid dielectric. The term “ flashover” is used when a disruptive discharge occurs over the surface of a solid dielectric in a gaseous or liquid medium. The term “ puncture” is used when a disruptive discharge occurs through a solid dielectric. Type test A test of one or more devices made to a certai
48、n design to show that the design meets certain specifications (IEV 151-04-15). Routine test A test to which each individual device is subjected during or after manufacture to ascertain whether it complies with certain criteria (IEV 151-04-16). Sampling test A test on a number of devices taken at ran
49、dom from a batch (IEV 151-04-17). Acceptance test A contractual test to prove to the customer that the device meets certain conditions of its specification (IEV 151-04-20).
