ULC CAN/ULC 652:2024 Standard for Tank Assemblies for the Collection, Storage and Removal of Used Oil

PREFACE

This is the Third Edition of the Standard for Tank Assemblies for the Collection, Storage and Removal of Used Oil, CAN/ULC 652.

This Edition of the Standard has been formally approved by the ULC Standards Committee on Stationary Steel Storage Containers for Flammable and Combustible Liquids.

This Standard has been developed in compliance with the requirements of Standards Council of Canada (SCC) for accreditation of a Standards Development Organization.

Only metric SI units of measurement are used in this Standard. If a value for measurement is followed by a value in other units in parentheses, the second value may be approximate. The first stated value is the requirement.

Appendix A, identified as Normative, forms a mandatory part of this Standard.

Appendices B and C, identified as Informative, are for guidance and information purposes only.

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 Third Edition National Standard of Canada is based on, and now supersedes, the Second Edition.

Attention is drawn to the possibility that some of the elements of this Canadian standard may be the subject of patent rights. ULC Standards shall not be held responsible for identifying any or all such patent rights.

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.

This CAN/ULC 652 Standard is under continuous maintenance, whereby each revision is approved in compliance with the requirements of 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.

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 thei Collaborative Standards Development System (CSDS) at https://csds.ul.comi.

This Standard is intended to be used for conformity assessment.

SCOPE

1.1 This Standard sets forth the minimum requirements for the adaptation of tanks or tank assemblies for the collection, storage and removal of used oil.

1.2 The stationary installation and use of used oil tank assemblies, may be covered by the requirements of the authority having jurisdiction and may include by reference, but not limited to the following:

A National Fire Code of Canada, Part 4;

B CSA B139, Installation code for oil-burning equipment; and

C CCME PN 1326, Environmental Code of Practice for Aboveground and Underground Storage Tank Systems Containing Petroleum and Allied Petroleum Products.

1.3 Standards for the tanks or tank assemblies covered by this Standard are identified in Section 4, Construction. As a result of revisions to those Standards published in 2019, in addition to traditional safety requirements for tanks that primarily evaluate functional operation, structural integrity, and mitigate fire & environmental hazards from loss of liquid containment under expected normal conditions; optional construction and/or performance requirements, and associated ratings, intended to address more severe conditions associated with the effects of Climate Change are now specified in an optional Climate Change Adaptation Appendix in each of those Standards.
