Draw a 38mm diameter, 19mm radius, circle and cut into four equal pieces,
Radius is measured by a quadrant.

get a bit of wood, drill a 38 mill hole. Throw the middle bit you've just drilled away. Cut the wood you're left with (which has the hole
in it) into 4 equal parts. See if the radius of the bit matches the 1/4 you've got.

How far does the 19mm radius have to go round the bottom edge of the instrument/dash panel?
Is it checked going forward or is it also checked coming back towards the driver?

I believe it needs to have a "deformable" (i.e. covered foam) covering for IVA as well

19mm radius if solid
and 5mm if it foamed (not quite sure its 5mm but some will correct me)
the dash in the pic does seam to have all the correct radii to get through the IVA but the prof is in the eating
i mean testing

You're quite right; 19 if solid, 5 if foamy 
"7. The instrument panel lower edge within the “specified zone” must have a radius of curvature not less than 19mm or 5mm and covered with a
non-rigid material. Except where an adaptation for a disabled person makes it impossible to comply. (see note 7) "
