REVISE THE LIFT LUG REQUIREMENTS RATIONALE During the past couple of years, a UUULC Subject 1746 Technical Harmonization Committee has been comparing the UL and Underwriters Laboratories of Canada (ULC) external corrosion protection
25、requirements and recommending the adoption of one set of requirements for both safety organizations. For requirements that appear in multiple UL standards (.e. UL 58 and UL 1746) their recommendation would apply to both UL standards. Recently, the Technical Harmonization Committee made a recommendat
26、ion regarding the lift lug requirements. The committee requested that ULC adopt the lift lug requirements published in UL 58 and UL 1746. The harmonization of the requirements in ULC S603-92, the Standard for Steel Underground Tanks for Flammable and Combustible Liquids, UL 58 and UL 1746 would redu
27、ce the cost and time for tank investigations. UL is proposing to have the following requirements for lift lugs: (1) Use lift lugs with the design and location requirements published in ULC S603-92 and not perform a Lift Lug Test, (2) Perform the Lift Lug Test, or (3) Use structural analysis by calcu
28、lations and not perform a Lift Lug Test. The proposed requirements also indicate that all tanks are to be provided with a lift lug). Copyright Underwriters Laboratories Inc.

CLARIFICATION TO THE MINIMUM STEEL SHELL THICKNESS REQUIREMENTS RATIONALE After reviewing comments received from industry in response to the ANSI canvass of UL 58, UL is proposing to clarify the shell thickness, length, and diameter requirements for
32、underground tanks. Please note that the revised requirements clarify that when the External Pressure Test is conducted, the tank that is evaluated has the reduced shell thickness. UL has already clarified the shell thickness, length, and diameter requirements in the Safety Standard for External Corr
33、osion Protection Systems for Steel Underground Storage Tanks, UL 1746. See the UL 1746 revision pages dated May 16, 2000. IMPACT Since this proposed revision will not necessitate a review or additional testing of currently Listed or Recognized products, UL proposes that the new requirements become e
34、ffective immediately upon publication. PROPOSALS Paragraphs 5.1.1, 5.1.2, 5.1.4, 5.2.2, and 5.3.1 3. REVISE THE MAXIMUM CAPACITY REQUIREMENT AND PROPOSE TO ADD A MAXIMUM DIAMETER REQUIREMENT RATIONALE Based on requests received from industry during the ANSI canvass of UL 58, UL is proposing to revis
35、e the tank capacity requirement to be at least equal to rated capacity, but not more than 110 percent of the nominal rated capacity. The revised capacity requirement would provide consistent capacity requirements in UL 142, the Standard for Steel Aboveground Tanks for Flammable and Combustible Liqui
36、ds, and UL 58. UL is proposing to add a 144 inch maximum tank diameter requirement to clarify current practice. Copyright Underwriters Laboratories Inc.

PROVIDE CONSISTENT REQUIREMENTS IN SECTIONS 9 AND 15 RATIONALE To maintain consistency with paragraph 15.4 in the Subject standard and UL 142, UL is proposing to revise and clarify that the inside knuckle radius shall be 1.5 times the head plate thickness in parag
39、raph 9.3. In addition, UL is proposing to revise paragraph 15.1 to state that a head of a secondary containment tank shall be constructed of not more than three pieces for diameters ranging from 49 to 96 inches. The revision will provide consistency with paragraph 9.1. IMPACT Since this proposed rev
