Engulfing fire test Sample Clauses

The Engulfing Fire Test clause defines the criteria and procedures for evaluating how a material or structure responds when completely surrounded by fire. In practice, this clause outlines the specific testing conditions, such as temperature thresholds and exposure durations, that must be met to simulate a real-world fire scenario. By establishing standardized testing methods, the clause ensures that products or constructions meet safety requirements, thereby reducing the risk of catastrophic failure during an actual fire event.
Engulfing fire test. The test unit is the compressed hydrogen storage system. The storage system is filled with compressed hydrogen gas at 100 per cent NWP (+2/-0 MPa). The container is positioned horizontally with the container bottom approximately 100 mm above the fire source. Metallic shielding is used to prevent direct flame impingement on container valves, fittings, and/or pressure relief devices. The metallic shielding is not in direct contact with the specified fire protection system (pressure relief devices or container valve). A uniform fire source of 1.65 m length provides direct flame impingement on the container surface across its entire diameter. The test shall continue until the container fully vents (until the container pressure falls below 0.7 MPa). Any failure or inconsistency of the fire source during a test shall invalidate the result. Flame temperatures shall be monitored by at least three thermocouples suspended in the flame approximately 25 mm below the bottom of the container. Thermocouples may be attached to steel cubes up to 25 mm on a side. Thermocouple temperature and the container pressure shall be recorded every 30 seconds during the test. Within five minutes after the fire is ignited, an average flame temperature of not less than 590 °C (as determined by the average of the two thermocouples recording the highest temperatures over a 60 second interval) is attained and maintained for the duration of the test. If the container is less than 1.65 m in length, the centre of the container shall be positioned over the centre of the fire source. If the container is greater than

If the container is less than 1.65 m in length, the centre of the container shall be positioned over the centre of the fire source. If the container is greater than 1.65 m in length, then if the container is fitted with a pressure relief device at one end, the fire source shall commence at the opposite end of the container. If the container is greater than 1.65 m in length and is fitted with pressure relief devices at both ends, or at more than one location along the length of the container, the centre of the fire source shall be centred midway between the pressure relief devices that are separated by the greatest horizontal distance. The container shall vent through a pressure relief device without bursting. 1. TPRD Qualification Performance Tests Testing is performed with hydrogen gas having gas quality compliant with ISO 14687-2/SAE J2719. All tests are performed at ambient temperature 20 (±5) °C unless otherwise specified. The TPRD qualification performance tests are specified as follows (see also Appendix 1):

Engulfing fire test. The container may be subjected to engulfing fire without any shielding components. The test unit is the compressed hydrogen storage system. The storage system is filled with compressed hydrogen gas at 100 % of NWP. The container is positioned horizontally with the container bottom approximately 100 mm above the fire source. Metallic shielding is used to prevent direct flame impingement on container valves, fittings, and/or pressure relief devices. The metallic shielding is not in direct contact with the specified fire protection system (pressure relief devices or container valve).

The container shall vent through a pressure relief device without bursting [5].
