I know that tow balls are rated but I have no idea what number translate to,
anyone know ?
e11 A50-X 00-0997 D12,6 S154
I've found that the e is the country code but that's about it.

If you don't get an answer before then, I'll look the standard up when
I'm back in the office on Friday.

OK, here goes with my best attempt. It's a bit technical
e11 - "e" is the conformity mark, "11" refers to the UK as the
certifying country.
A50-X - this is probably the manufacturer's part number.
00-0997 - this identifies the manufacturer in some fashion.
D12,6 - the ball is rated for a dynamic load of 12.6 kN (approx 1.28
tonnes force).
S154 - the ball is rated for a static load (noseweight) of 156 kg.
Now, "D" is a slightly artifical value calculated from the mass of the
towing car MT and of the towed load ML by the formula:
D = g x (MT x ML) / (MT + ML)
where g is the acceleration due to gravity.
If you've got a 3.5-tonne towcar and a potential 3.5-tonne load, you
need a D value of 17.2 -ish.
Any help?

And another from Tony Maris,
Hello Graham!
Good job I recognized the name, with a subject like that, you were
nearly deleted as Spam!
e11 means it was type approved in the UK.
A50-X is the class of coupling. This is a fairly application.
00-0997 is the type approval number.
D12.6 is the 'D' value in kiloNewtons. (I'll come back to that). S 154
is the maximum allowable static download in kilos, or noseweight.
D value is a bit complicated. In effect it is the capacity of the ball
to pull something, but it is actually a combination of the Gross Vehicle
Weight and the Gross Trailer Weight. As one goes up, the other must go
down.
A 'D' value of 17.4 is the highest normally tested to on a flange ball
using a 2 bolt fixing. This equates to a 3,500 kg gross vehicle pulling
a 3,500 kg gross trailer. If the same trailer were to be pulled by (for
instance) a 10 tonne truck, a 50mm ball should not be used but an eye
coupling. The 'D' values can go much higher on eye couplings.
To calculate 'D' value, the formula is GVW x GTW / GVW +GTW all times
by 9.81/1000. try it with 3,500 in both cases. It should be around
17.2kN.
For information the constant (9.81) is the acceleration due to gravity
expressed in metres per second. (or is it per second, per second?) Its
a long time since I did ONC physics!
I hope you and yours are keeping well.............
