ACI318M-11, 10.6.7, Skin Reinforcement

[Nonlinearer]

In my ACI318m-11 (metric version), clause 10.6.7, the requirement of skin reinforcement arises if beam depth is more than 400mm. Can any body check? What I remember, it was 900mm (36") in previous codes. If this is a typo, is it covered in errata?

I have ACI 318-11. Section 10.6.7 - Where h of a beam or joist exceeds 36 in., longitudinal skin reinforcement.......... Seems there is an error in conversion.

Don't have it in front of me, but it's been 36 inches in ACI since I started a few years ago.
