Section 408.7060. Three-year inspection and test requirements.

Rule 60.  Section 8.6.5.15.3 is added to the ASME A17.1 code to read as follows: 8.6.5.15.3. (1) Cylinders shall be tested at intervals of not more than 36 months.

(2)     Three-year inspection and test requirements.

(a)     The relief valve setting shall be in compliance with section 3.19.4.2 of the ASME A17.1 code. The relief valve shall be resealed if the relief valve setting is altered or if the seal is broken.

(b)     Test the relief valve setting by first inching the empty car upward to engage the plunger stop ring or to engage other suitable blocking provided and then apply pressure from the pump to check the setting.

Procedures for set test are as follows:

(i)     Put rated load in the car and locate it at any convenient level.

(ii)     Open the disconnect switch and locate the elevation of the platform with respect to a convenient reference.

(iii)     For cylinders that are not completely exposed, after not less than 2 hours, note the position of the platform with respect to the chosen reference.  For cylinders that are completely exposed, after not less than 30 minutes, note the position of the platform with respect to the chosen reference. A change in the car position during a cylinder test that cannot be accounted for by visible oil leakage or temperature change of the oil indicates a failure of some type requiring further inspections, tests, or repairs.  An accessible written record of all oil levels and all oil added shall be maintained in the machine room.
