Heat transfer efficiency : based on tests with a speed of air of 1 m/sec, and a velocity of water in the tubes of 40 cm/sec.

Influence of surface treatment :

- painting :	-10%
- galvanisation :	+10%

Tolerances :

on outside diameter	=	± 1%
on thickness of tubes	=	± 10%
on the diameter of the fins	=	± 3%
on the thickness of the fins	=	± 20%
on the number of fins	=	8 p. M.
on the total length	=	± 3 mm
