EN10216-5 Hydraulic Steel Tube Delivery Condition:

Tubes are delivered in the solution-annealed condition.

Symbol b	Type of delivery condition	Surface condition
HFD	Hot finished heat treated, descaled	Metallically clean
CFD	Cold finished heat treated, descaled	Metallically clean
CFA	Cold finished bright annealed	Metallically bright
CFG	Cold finished heat treated, ground	Metallically bright-ground, the type and degree of roughness shall be agreed at the time of enquiry and order c
CFP	Cold finished heat treated, polished	Metallically bright-polished, the type and degree of roughness shall be agreed at the time of enquiry and order c
a Combinations of the different conditions may be agreed at the time of enquiry and order. b The symbols are abbreviations for type of condition. Example: CFD = Cold Finished Descaled. c The enquiry and the order shall indicate whether the roughness requirement applies on the internal or external tube surface, or internal and external.
