Scope:

1.1 This Standard sets forth minimum requirements for sacrificial magnesium and

zinc anodes and zinc reference electrodes which are intended for use in the cathodic protection

of steel underground tanks which have been coated and installed in accordance with the

requirements contained in CAN/ULC-S603.1, Standard for External Corrosion Protection

Systems for Steel Underground Tanks for Flammable and Combustible Liquids.

1.2 Requirements contained in this Standard apply to cored anodes of the following

types:

A High and standard potential magnesium anodes;

B Zinc anodes;

C Zinc reference electrodes; and

D Copper/copper sulphate reference electrodes.

NOTE: High potential magnesium anodes are intended for retrofit applications only and shall be

sized according to the specifications of the corrosion specialist in charge of the retrofit

application.

Project need:

**Please refer to the posting on CAN/ULC-S603.1; During the Preliminary review of ULC-S618 and ULC-S631, the ULC Standards Committee on Stationary Steel Storage Containers for Flammable and Combustible Liquids has decided to integrate both standards into CAN/ULC-S603.1. Therefore, ULC-S618 and ULC-S631 will be superseded by CAN/ULC-S603.1, once the new edition is published.
