Hi all.
Could someone please tell me the maximum length of undercut allowed within UW-51.
Iíve had many contradictions regarding length allowed, seems a bit of a grey area.
Thanks in advance

Mark,
Not easy to find.
No maximum length given.
It either complies with below or not.

UW-35
(2) The reduction in thickness shall not exceed
1/32 in. (1 mm) or 10% of the nominal thickness of the adjoining
surface, whichever is less.

Hope that helps,
BB
