Hilti heavy duty anchor HSL4
Annex C12
Table C14: Chracteristic tension resistance under fire exposure for Hilti metal
expansion anchor HSL4, HSL4-G, HSL4-B, HSL4-SK in cracked and
uncracked concrete
1)
Pull-out failure is not decisive for design.
2)
In absence of other national regulations the partial safety factor for resistance under fire exposure γM,fi = 1,0 is
recommended.
