ISO 6944 - FIRE RESISTANCE TESTS - VENTILATION DUCTS - FIRST EDITION Organization: ISO
Date: 1985-01-01
Description: The general purpose of this test is to measure the ability of a representative duct or duct assembly to resist the spread of fire from one fire compartment to another without the aid of fire dampers.
UL 2221 - UL STANDARD FOR SAFETY TESTS OF FIRE RESISTIVE GREASE DUCT ENCLOSURE ASSEMBLIES - SECOND EDITION Organization: UL
Date: 2010-08-13
Description: In addition, these requirements evaluate the effectiveness of the combination of the grease duct and the enclosure as a fire rated enclosure system and through penetration firestop system, as well as the enclosure's effect on the grease duct. The fire endurance ratings for grease duct enclosure assemblies are intended to register performance during the period of fire exposure and are not intended to be interpreted as having determined the acceptability of the grease duct assembly for use before or after fire exposure.
UL 2443 - UL STANDARD FOR SAFETY FLEXIBLE SPRINKLER HOSE WITH FITTINGS FOR FIRE PROTECTION SERVICE - THIRD EDITION; REPRINT WITH REVISIONS THROUGH AND INCLUDING NOVEMBER 23, 2016 Organization: UL
Date: 2015-08-05
Description: This standard covers flexible sprinkler hose with fittings intended for direct connection to fire sprinklers in installations requiring a flexible attachment to the sprinkler system piping such as clean rooms, suspended ceilings, and exhaust ducts.
UL 555 - UL STANDARD FOR SAFETY FIRE DAMPERS - SEVENTH EDITION; REPRINT WITH REVISIONS THROUGH AND INCLUDING OCTOBER 21, 2016 Organization: UL
Date: 2006-07-12
Description: Fire dampers for dynamic systems are intended for use where the airflow is operational at the time of fire, such as in a smoke control system, or from other situations in which the fan system is operational at the time of a fire. Where fire dampers are required in ducts that penetrate fire barriers and where the duct is also used as part of a smoke control system, the system designer shall ascertain which type of fire damper is appropriate for the application.
ULC CAN-S115 - STANDARD METHOD OF FIRE TESTS OF FIRESTOP SYSTEMS - FOURTH EDITION Organization: ULC
Date: 2011-06-01
Description: This method of test is applicable to firestop systems with or without penetrating items such as cables, cable trays, conduits, ducts and pipes. These firestop systems are intended for use in openings in fire resistive wall and floor assemblies and membranes forming part of an assembly required to have a fire resistance rating and linear openings between adjacent fire resistive floor assemblies, wall assemblies or both Tests conducted in conformance with this method will record firestop performance during the fire-test exposure under laboratory conditions; but such tests shall not be construed as determining suitability of the firestop system for use after exposure to fire.
