Aerospace series - Electrical cables, installation - Protection sleeves - Test methods - Part 502: Resistance to electrical arcs
This standard specifies a method of assessing the behaviour of protection sleeves or conduits subject to an external electric arc, either at 115 Vac or 230 Vac 400 Hz.
This Standard shall be used together with EN 6059-100.
The primary aim of this test is to produce, in a controlled fashion, electric arcs at the immediate vicinity of a protection sleeve or conduit and to examine possible consequences on cables inside this protection, which are supposed to be maintained in a safe condition. These electric arcs are representative of those, which may occur in service when a typical cable bundle is severely damaged.
In order to optimize thickness and mass of such protection, it is necessary to associate a current limit In to each sleeves or conduits construction.
Two levels of prospective fault current are specified for all protection sizes.

Aeronavtika - Električni kabli, namestitev - Zaščitne obojke - Preskusne metode - 502. del: Odpornost proti električnim oblokom
Ta standard določa metodo za preskušanje obnašanja zaščitnih obojk ali kanalov pri zunanjem električnem obloku, in sicer pri 115 Vac ali 230 Vac 400 Hz.
Ta standard je treba uporabljati s standardom EN 6059-100.
Glavni cilj tega preskusa je na nadzorovan način ustvariti električne obloke v neposredni bližini zaščitne obojke ali kanala ter preučiti morebitne posledice na kablih znotraj te obojke, ki naj bi bili ohranjeni v varnem stanju. Ti električni obloki so reprezentativni za tiste obloke, ki se lahko pojavijo med obratovanjem, ko je običajen snop kablov resno poškodovan.
Da bi se dosegli čim bolj ustrezno debelino in maso take obojke, je treba pri vsaki konstrukciji obojke ali kanala določiti mejo toka.
Določeni sta dve ravni pričakovanega okvarnega toka za vse velikosti obojk.

4 Definition and preparation of specimen
4.1 Protected bundle (bundle P)
Bundles P are made of arc tracking resistant cables, typically from EN 2267-010 product standard unless
otherwise specified in the concerned protection sleeves product standard, with bundle external protection to
be tested.
The cable bundle outer diameter shall be as closed as possible to the internal diameter of the protection to be
tested. This diameter is obtained:
with a full assembly of size 24 cables, or
with a central part in various cable types covered with a full and uniform layer of size 24 cables.
The sleeve shall be fitted in accordance with the manufacturer’s declared fitting instructions.
4.2 Aggressive bundle (bundle A)
4.2.1 Definition and constitution
Bundles A are made of 7 arc-tracking resistant cables, typically from EN 2267-010 product standard unless
otherwise specified in the concerned protection sleeves product standard, without bundle external protection.
The short circuit will be created on these bundles (see 4.3).
The cables gauge is chosen in Table 1, in accordance with the In limit specified for the protection sleeves.
