This document contains specific requirements for gaseous fire-extinguishing systems, with respect to FK-5-1-12 extinguishant. It includes details of physical properties, specifications, usage and safety aspects. This document is applicable only to systems operating at nominal pressures of 25 bar, 34,5 bar, 42 bar and 50 bar with nitrogen propellant. This does not preclude the use of other systems.

1 Domaine d’application 1.1 Cette norme s’applique aux réfrigérateurs-chambres et aux congélateurs-chambres (c.-à-d., un espace d’entreposage réfrigéré et fermé dans lequel il est possible d’entrer) ayant une zone totale d’entreposage réfrigérée de moins de 278,71 m2 (3000 pi2). 1.2 Cette norme ne s’applique pas aux appareils frigorifiques commerciaux traités dans CAN/CSA-C657. 1.3 L’…

1 Scope 1.1 This Standard applies to individual gas appliance pressure regulators, which are not a part of a combination control (see Clause 3, Definitions), constructed entirely of new, unused parts and materials, hereinafter referred to as regulators, intended for application on individual gas appliances. This Standard also applies to negative gas appliance pressure regulators (see Clause 3…

1 Scope 1.1 This Standard provides the minimum requirements, unless otherwise specified by the authority having jurisdiction, for the purity of compressed breathing air supplied to the service outlet and for breathing air systems required to produce, store, and distribute such air. 1.2 This Standard is limited to compressed breathing air and compressed breathing air systems used in the…

1.1 This Standard establishes the test method, criteria, and device to evaluate a hydrogen fueling station dispensing system (hereinafter referred to as a “dispenser”) as it relates to achieving the protocols specified in SAE J2601 and SAE J2799 with light duty vehicle hydrogen storage systems less than 248.6 L (10 kg H70). The testing evaluation applies to dispensers designed to fill vehicle…
