Scope:

1.1 The Standards for foam liquid concentrates are divided into three categories.

Category 1 - Primarily for use on general-purpose hydrocarbon fires               

Category 2 - Primarily for use on polar solvents, oxygenated fuels, and water-miscible fuels and all Category 1 applications               

Category 3 - Primarily for use on aircraft rescue firefighting and all Category 1 applications               

This Standard refers to Categories 1 and 2 foam liquid concentrates.

NOTE: The requirements for Category 3 Aqueous Film-Forming Foam (AFFF) Liquid Concentrates are contained in the Standard CAN/ULC-S560 and the requirements for Category 3 Film-Forming Fluoroprotein (FFFP) Foam Liquid Concentrates are contained in the Standard CAN/ULC-S563.

1.2 These requirements cover foam producing equipment and liquid concentrates employed for the production and discharge of foam that has an expansion ratio of 20:1 or less and is used for fire extinguishment. These requirements are based on the premise that foam equipment and specified types of foam liquid concentrates with which they are intended to be used are to be investigated for use with each other.

1.3 If foam equipment covered by these requirements incorporate sprinklers, the sprinklers shall comply with the requirements for Automatic Sprinklers for Fire-Protection Service, ULC/ORD-C199.

1.4 Requirements for the installation and use of foam equipment and foam liquid concentrates are included in the Standard for Low-, Medium-, and High-Expansion Foam, NFPA 11.

Project need:

The following proposals to ULC S564 are being made to align ULC S564 with UL 162: 1. Floor Level Nozzles - Trench/Grate Nozzles 2. Addition of Separation Test 3. Removal of maximum drain time requirement for foams with extended drain times 4. Rectify Safety Factor Inconsistencies 5. Editorial correction to Table 11.2
