BS EN 1591-4 on personnel competency in bolted connection assembly is useful for:

ISO 12858-2 is the second part of the ISO 12858 series of documents that specifies the most important requirements of telescopic tripods for surveying instruments and the connection between instrument and tripod

and so on)

Some provisions in Annex C are for national determination - so an amendment to the UK National Annex to BS EN 1993-1-1 is now published that provides the necessary national rules

Founding. Ausferritic spheroidal graphite cast irons Ingestion-build-135476 BS EN 1591-4 on personnel1 Scope This European Standard defines the grades and the corresponding requirements for ausferritic spheroidal graphite cast irons. This European Standard specifies five grades of ausferritic spheroidal graphite cast iron by a classification based on mechanical properties measured on machined test pieces prepared from cast samples. This European Standard also specifies two grades by a classification as a function of hardness. This European Standard
