when tested according to the provisions specified in ANSI B175.1-2012.

Kickback and guide bar nose radius
For sprocket nose bars the nose radius is defined by the number of teeth (e.g. 10T). For solid bars the nose radius is
defined by the size of the nose radius. For a given guide bar length, you may use a guide bar with smaller nose radius
than listed.
