3.2
specified minimum failure load
SMFL
minimum load, specified by the purchaser or declared by the supplier, at which mechanical failure will not
take place
Note 1 to entry: From the probabilistic point of view, the specified minimum failure load corresponds to the value
having the probability of e % in the distribution function of the strength of the fitting. The exclusion limit e % is usually
taken within 2 % to 5 % with 10 % being the upper limit (see IEC 60826).
3.3
slippage factor
X-value
ratio between the tensile force on the covering of the conductor when a certain slippage starts to occur and
the RTS of the conductor
Note 1 to entry: See EN 50397-1:2006, Annex D.
Note 2 to entry: An X-value of e.g. 100 % means that at a force up to RTS no relative slippage between the covering
and the conductor occurs.
