Draft
This document specifies a method of assessing the behaviour of protection sleeves or conduits subject to an external electric arc at 115 Vac, 400 Hz.
This document is used in conjunction 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 the surrounding external cables bundle which are adjacent from this protection, and 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 nominal current limit In to each sleeves or conduits construction.
Two levels of prospective fault current are specified for all protection sizes.
