AND CONFORMITY: KRS 236.030 authorizes the commissioner, through the Board of
Boiler and Pressure Vessel Rules, to fix reasonable standards for the safe
construction, installation, inspection and repair of boilers, pressure vessels
and pressure piping. This administrative regulation sets forth the definitions
used in the boiler and pressure vessel safety rules. This amendment is necessary
to meet KRS Chapter 13A as determined by quadrennial review, as well as to
clarify how newer codes are utilized.
