NOTE Connecting components which are not standardized at pre

21、sent may be used, this being subject to agreement. It should, however, be noted, that the loadability of such components does not necessarily comply with that of the turnbuckle. 11 Assembly and loadability Turnbuckles complying with this standard shall be assembled with welding studs as specified in

22、 DIN 34828 which are made of the same steel (S235JR). The loadability of such assemblies is higher than that of the welding studs. When using turnbuckles with connecting components made of other materials, in particular materials of higher strength, the loadability of the assembly shall be determined separately.
