ANSI/CAN/UL/ULC 79A:2024 STANDARD FOR SAFETY Power-Operated Pumps for Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations up to 85 Percent (E0 – E85)
Preface
This is the Second Edition of ANSI/CAN/UL/ULC 79A, Standard for Power-Operated Pumps for Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations up to 85 Percent (E0 – E85).
ULSE is accredited by the American National Standards Institute (ANSI) and the Standards Council of Canada (SCC) as a Standards Development Organization (SDO). ULC Standards is accredited by the Standards Council of Canada (SCC) as a Standards Development Organization (SDO).
This Standard has been developed in compliance with the requirements of ANSI and SCC for accreditation of a Standards Development Organization.
This ANSI/CAN/UL/ULC 79A Standard is under continuous maintenance, whereby each revision is approved in compliance with the requirements of ANSI and SCC for accreditation of a Standards Development Organization. In the event that no revisions are issued for a period of four years from the date of publication, action to revise, reaffirm, or withdraw the standard shall be initiated.
Annex A, identified as Normative, forms a mandatory part of this Standard.
In Canada, there are two official languages, English and French. All safety warnings must be in French and English. Attention is drawn to the possibility that some Canadian authorities may require additional markings and/or installation instructions to be in both official languages.
This Second Edition joint American National Standard and National Standard of Canada is based on, and now supersedes, the First Edition of UL 79A.
Requests for interpretation of this Standard should be sent to ULC Standards. The requests should be worded in such a manner as to permit a “yes” or “no” answer based on the literal text of the requirement concerned.
Comments or proposals for revisions on any part of the Standard may be submitted at any time. Proposals should be submitted via a Proposal Request in the Collaborative Standards Development System (CSDS) at https://csds.ul.com.
Our Standards for Safety are copyrighted by ULSE Inc. Neither a printed nor electronic copy of a Standard should be altered in any way. All of our Standards and all copyrights, ownerships, and rights regarding those Standards shall remain the sole and exclusive property of ULSE Inc.
This Edition of the Standard has been formally approved by the Technical Committee (TC) on Power[1]Operated Pumps for Petroleum Dispensing Products, TC 79.
This list represents the TC 79 membership when the final text in this standard was balloted. Since that time, changes in the membership may have occurred.

1 Scope
1.1 These requirements cover products described in 1.3 when used with one or more of the fuels described in 1.4.
1.2 Pumps for gasoline/ethanol blends with nominal ethanol concentrations up to 85 % (E0 – E85) shall be constructed to comply with the following:
a) The requirements defined in the Standard for Power-Operated Pumps for Petroleum Dispensing Products, UL/ULC 79; and
b) The requirements in this Standard.
1.3 This Standard sets forth minimum requirements for electrically-, hydraulically-, or pneumatically[1]driven power-operated pumps for use with petroleum products in the following applications:
a) Self-contained dispensing devices and submerged pumps used in storage tanks that provide the fuel to remote control dispensing devices. They are intended for operation at discharge pressures of 345 kPa (50 (psig) , or the marked maximum discharge pressure rating, when less, with the ambient and liquid temperature within the range of –29 °C (–20 °F) to 52 °C (125 °F).
b) Dispensing systems to transfer the fuel from a tank or container to a vehicle or another container. They are intended for operation at the marked maximum discharge pressure, or less, with the ambient and liquid temperature within the range of –29 °C (–20 °F) to 52 °C (125 °F).
c) Vapor recovery applications for dispensing devices. They are intended to operate under a vacuum at the inlet and a maximum discharge pressure of 345 kPa (50 psig), or marked discharge pressure, whichever is less.
1.4 Pumps covered by these requirements are intended for use with one or more of the following:
a) Gasoline formulated in accordance with the Standard Specification for Automotive Spark-Ignition Fuel, ASTM D4814;
b) Gasoline/ethanol blends with nominal ethanol concentrations up to 25 % ethanol (E25), consisting of gasoline formulated in accordance with the Standard Specification for Automotive Spark-Ignition Fuel, ASTM D4814, when blended with denatured fuel ethanol formulated to be consistent with the Standard Specification for Denatured Fuel Ethanol for Blending with Gasolines for Use as Automotive Spark-Ignition Engine Fuel, ASTM D4806; or
c) Gasoline/ethanol blends with nominal ethanol concentrations above 25 % formulated in accordance with the Standard Specifications in (b) or formulated in accordance with the Standard Specification for Ethanol Fuel Blends for Flexible-Fuel Automotive Spark-Ignition Engines, ASTM D5798, as applicable.
