Full title and description
St UL 58 2018-01 — UL 58: Standard for Steel Underground Tanks for Flammable and Combustible Liquids (Edition 10). Requirements for the design, fabrication, inspection and leakage testing of horizontal atmospheric-type steel tanks intended for underground storage of flammable and combustible liquids, including single-wall and secondary-containment constructions and multiple-compartment tanks.
Abstract
This 2018 edition of UL 58 (edition 10, published January 31, 2018) establishes construction, inspection, and factory-testing requirements for cylindrical steel underground storage tanks used to store flammable and combustible liquids. It clarifies allowable tank types (single-wall, secondary-containment, and multi-compartment), fabrication and assembly expectations, and the factory leakage tests these tanks must pass prior to shipment. Corrosion protection systems are outside the scope and are addressed by separate UL requirements.
General information
- Status: Current (edition 10, published January 31, 2018).
- Publication date: January 31, 2018.
- Publisher: Underwriters Laboratories (UL).
- ICS / categories: 13.100 (Occupational safety; Industrial hygiene), 13.300 (Protection against dangerous goods).
- Edition / version: Edition 10 (2018-01-31).
- Number of pages: 35 pages.
Scope
UL 58 covers horizontal atmospheric-type cylindrical steel tanks fabricated and intended for underground installation to store flammable and combustible liquids. It applies to single-wall tanks, secondary-containment tanks, and multiple-compartment variants that are fabricated, inspected, and factory-tested for leakage before shipment as complete vessels. The standard does not apply to welded steel tanks covered by API 650, to tanks intended for chemical/petrochemical plant service, nor does it address corrosion protection systems (see UL 1746 for external corrosion protection).
Key topics and requirements
- Design and construction requirements for horizontal atmospheric-type steel underground tanks.
- Requirements for single-wall tanks, secondary-containment tanks, and multiple-compartment tanks.
- Fabrication and weld quality, dimensional and material requirements for cylindrical tank sections.
- Factory inspection procedures and acceptance criteria.
- Leakage and hydrostatic testing methods required prior to shipment.
- Installation references and coordination with applicable codes (e.g., NFPA and International Fire Code) but not installation practice details.
- Explicit exclusion of corrosion protection requirements; cross-reference to UL 1746 for external corrosion protection systems.
- Clarifications on items outside scope (API 650 tanks; tanks for certain industrial plant uses).
Typical use and users
Manufacturers of underground fuel and liquid storage tanks, tank fabricators, quality inspectors, third‑party testing bodies, installers and site contractors, facility owners/operators in petroleum and fuel distribution, fire marshals, code officials, and engineers specifying underground storage for flammable or combustible liquids.
Related standards
Commonly referenced standards and codes: UL 1746 (External Corrosion Protection Systems for Steel Underground Storage Tanks), API 650 (Welded Steel Tanks for Oil Storage) — excluded by scope, NFPA 30 (Flammable and Combustible Liquids Code), NFPA 31 (Installation of Oil‑Burning Equipment), NFPA 30A (Automotive and Marine Service Station Code), NFPA 37, NFPA 1 (Fire Code), and the International Fire Code. Local, state or federal regulations may impose additional corrosion protection or installation requirements.

FAQ
Q: What is this standard?
A: UL 58 is the Underwriters Laboratories standard that sets construction, inspection and factory-testing requirements for horizontal atmospheric-type steel underground tanks used to store flammable and combustible liquids. The edition referenced here is edition 10, published January 31, 2018.
Q: What does it cover?
A: It covers design and fabrication requirements for single-wall, secondary-containment, and multiple-compartment cylindrical steel underground storage tanks, plus factory inspection and leakage testing requirements. It does not cover corrosion protection systems or welded storage tanks covered by API 650.
Q: Who typically uses it?
A: Tank manufacturers, fabricators, inspectors, installers, petroleum facility operators, engineers, and code officials use UL 58 to ensure underground steel tanks meet recognized safety and testing requisitos prior to installation and service.
Q: Is it current or superseded?
A: The document supplied here is Edition 10, published January 31, 2018. Users should verify with Underwriters Laboratories for any revisions, corrigenda or later editions published after March 3, 2026 to confirm current status.
Q: Is it part of a series?
A: UL 58 is one UL safety standard addressing underground storage tanks and is commonly used together with related UL and industry standards (for example UL 1746 for corrosion protection). It is not a numbered series in itself but sits within UL’s family of product and safety standards for storage tanks and petroleum equipment.
Q: What are the key keywords?
A: Steel underground tanks, underground storage tank, flammable liquids, combustible liquids, secondary containment, leakage testing, UL 58, tank fabrication, UL 1746, NFPA 30.
