Jet fire testing

Jet-Fire Standard ISO 22899-1

The jet fire standard ISO 22899-1:2007 consists of simulating the thermal and mechanical loads resulting from high-pressure releases of flammable gas, pressurized liquefied gas or flashing liquid fuels. Jet fires give rise to high convective and radiative heat fluxes as well as high erosive forces.
This ISO standard was formulated on the basis of experience obtained by performing tests according to the Health & Safety Executive (“Offshore Technology Report OTI 95” 634: 1995).
According to the jet fire standard, in order to produce thermal and kinetic impact on a protected pipe, a 0.3 kg/s release of gas is injected into a shallow chamber, producing a fireball with an extended tail.

Hydrocarbon standard – UL 1709

The UL 1709 standard “Rapid Rise Fire Test of Protection Materials for Structural Steel” is one of the oldest and most frequently used furnace test standards for the Oil and Gas industry. The temperature rise of the UL1709 is more severe than the European hydrocarbon fire (HC). The temperature rises from ambient temperature to 1093°C close to the test specimen within 5 minutes and is 154°C above the HC temperature time curve at 5 minutes.
The tests will be realized under ISO 17025 accreditation, with or without witnessing from third party organizations (DNV, Lloyd’s…).
