CHAPTER 402-H.F.No. 2679 An act relating to boilers and engines; modifying provisions relating to hobby boilers and show engines; amending Minnesota Statutes 1992, section 183.411, subdivision 2; repealing Minnesota Statutes 1992, section 183.411, subdivision 1a. BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF MINNESOTA: Section 1. Minnesota Statutes 1992, section 183.411, subdivision 2, is amended to read: Subd. 2. [INSPECTION.] When used only for display and demonstration purposes, steam farm traction engines, portable and stationary show engines and portable and stationary show boilers shall be inspected every two years according to law. (a) Boilers or show engines of lap seam construction not certified in Minnesota or previously certified in Minnesota but that have been repaired or altered after certification, may be certified in Minnesota if: (1) all alterations have been done in accordance with American National Standard ANSI/NB23 R-404 or R-505; or (2) form R-1, report of alteration, has been prepared by a registered professional engineer with verification by the authorized inspection agency responsible for the in-service inspection of the object in accordance with American National Standard ANSI/NB23 R-502; or (3) the engine has received a certificate allowing operation, or repairs have been authorized under American National Standard ANSI/NB23 R-404.1, R-404.2, or R-404.3 in Minnesota or another jurisdiction that accepts the provisions of American National Standard ANSI/NB23 and an inspection has been completed by an inspector certified in Minnesota according to the standards set in paragraph (b). (b) A hobby boiler or show engine, not certified in Minnesota or any other jurisdiction must successfully complete, at the owner's expense, inspection by: (1) full radiographic examinationof the long orlongitudinal seamor ultrasonic examination or dye-penetrant examination or none of the above, at the discretion of the boiler inspector, of the long or longitudinal seam of lap-seam construction; and (2) ultrasonic examination for metal thickness (for purposes of calculating the maximum allowable working pressure the thinnest reading shall be used - see also American National Standard ANSI/NB23 I-303.8 and a safety factor of six shall be used in calculating maximum allowable working pressure on all non-ASME-code hobby and show boilers); and (3) magnetic particle or radiographic examination of areas where dye penetrant testing shows possible cracks; and (4) hydrostatic testing at 1-1/2 maximum allowable working pressure. (c) Further each such object shall successfully complete an inspection of: (1) the fusible plug; (2) the safety valve, which must be of American Society of Mechanical Engineer's approved design and set at the maximum allowable working pressure and sealed in an appropriate manner not allowing tampering with the valve setting without destroying the seal; and (3) the boiler power piping. Any longitudinal cracks found in riveted longitudinal seams requires that the vessel be sealed and not approved for use in Minnesota. If the boiler or show engine is jacketed, the jacket must be removed prior to inspection. Sec. 2. [REPEALER.] Minnesota Statutes 1992, section 183.411, subdivision 1a, is repealed.
