Porté:

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 fire fighting 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.

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.

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.

4. Requirements for the installation and use of foam equipment and liquid concentrates are included in the following Standards of the National Fire Protection Association:

A       Standard for Low Expansion Foam, NFPA 11;

B       Standard for the Installation of Deluge Foam-Water Sprinkler and Foam-Water Spray Systems, NFPA 16; and

C       Standard for the Installation of Closed-Head Foam-Water Sprinkler Systems, NFPA 16A.

Raison d’être du projet

The following proposals to ULC S564 are being made to align ULC S564 with NFPA 11 consistent with the Scope of ULC S564. 1. Deletion of reference to NFPA 16 and update of NFPA 11 title. 2. Addition of a definition for Synthetic Fluorine Free Foam (SFFF).  3. Addition of Combustion Ion Chromatography test. 4. Revision to Table 4 to allow higher application densities and addition of clarifying content. 5. Revision to Table 5 to allow higher application densities and addition of clarifying content.

Note : L’information ci-dessus a été recueillie et est diffusée par le Conseil canadien des normes (CCN) pour les besoins de son système de notification centralisé et transparent pour l’élaboration de nouvelles normes. Le système permet aux organismes d’élaboration de normes (OEN) accrédités par le CCN et aux membres du public d’être informés des nouveaux travaux d’élaboration de normes au Canada. Il donne aussi aux OEN accrédités la possibilité de repérer et de résoudre les cas de doubles emplois éventuels dans les normes et les travaux de normalisation.
