Section 1330.4 - Testing, inspection and approvals(a) Testing.--(1) An antique boiler shall be subjected to nondestructive testing to determine the maximum allowable working pressure. The department may require additional nondestructive testing, based on an inspection or other evidence which indicates significant change in the condition of the boiler. This test shall be performed by an ASME "S" Code stamp holder, who shall stamp the boiler with the month and year the test was performed, the maximum allowable working pressure and the "S" Code stamp holder's ASME Certificate of Authorization number.(2) All antique boilers shall pass a hydrostatic test at one and one-quarter maximum allowable working pressure every five years, or more frequently if the department, based on an inspection or other evidence, so requires. Hydrostatic tests shall be conducted in the presence of an inspector.(b) Inspection.--An antique boiler must be inspected annually by an inspector. The inspection shall include the following: (2) The safety valve, which must be of an approved design and must be set at the maximum allowable working pressure. The safety valve shall be sealed in a manner that does not allow tampering with the valve setting without destroying the seal.(3) A visual examination for any evidence of corrosion.(4) A visual examination for any evidence of leakage.(5) The boiler power piping, up to and including the first valve.(6) Confirmation that the testing requirements of subsection (a) have been completed.(7) Any other requirements specified in the department's regulations.(c) Approvals.--(1) Upon successful completion of the inspection required in subsection (b) and payment of the fee required in section 6 , the department shall approve the operation of an antique boiler. The department shall issue an operating sticker signifying this approval. This operating sticker shall be valid for a period not to exceed 13 months. The sticker shall indicate the year and month the inspection was performed and the year and month of the most recent hydrostatic test. The operating sticker shall be prominently displayed on the antique boiler.(2) All welding performed on antique boilers shall be done in accordance with the National Board Inspection Code. The owner shall notify the department prior to commencing such alterations or repairs. The department's approval shall expire automatically if alteration or repair of the boiler which involves welding does not meet the requirements of this paragraph.(d) Alternate approval.--An operating sticker shall not be required for an antique boiler which has a valid license, certificate or other operating permit from a state or territory whose licensing requirements have been determined by the department to meet or exceed the requirements of this act. The department shall annually publish a list of the states whose licensing requirements meet or exceed the requirements of this act.1988, Oct. 21, P.L. 1046, No. 119, § 4, imd. effective.
