				Serial Number. The State serial number on boilers shall be not less than 
				5/16" in height
				and shall be preceded by the letter "B". The State serial number on pressure
				vessels shall be not less than

				Certificate of Internal Inspection for Power Boilers. The Chief Inspector is
				authorized to extend, for a period not exceeding one year, or 2 years for power
				boilers having an output rated at or above 450,000 lbs/hr, the time within
				which power boilers are required to be internally inspected, subject to the
				following conditions and qualifications:
1)
				The analysis and treatment of feedwater for power boilers shall be under the
				supervision of a person qualified in the field of water chemistry.

				feedwater shall be for the purpose of controlling and limiting serious
				deteriorating, encrusting and sludging factors affecting the safety of the
				boiler.
3) The owner or user of
				power boilers must maintain, for examination by the inspector, accurate records
				of chemical and physical laboratory analyses of samples of the boiler water
				taken at regular intervals of not more than 24 hours operation and of the

				whom analyzed, and the treatment applied at that time, and should be certified

				of the water and any constituents or characteristics that are capable of
				producing corrosion or other deterioration of the boiler or its
				parts.

				450,000 lbs/hr.

				the period between internal inspections for boilers having an output rated at

7) Application for extension shall be by
				letter setting forth facts establishing compliance with the requirements of
				subsections (c)(1) through (c)(7) and shall be accompanied by the report of
