This standard states Approval requirements for rexplosion venting systems including fasteners and latches for damage limiting construction.
Accidental explosions in confined areas generally result in over-pressure situations where the actual pressures far exceed the design strength of the enclosure. This condition will result in significant damage to the enclosure which may be a room in a larger building or a separate stand alone building. To mitigate the potential damage caused by accidental explosions, some form of damage limiting construction (DLC) is needed. Explosion venting panels are used as an element of damage limiting construction. A common DLC design would combine venting panels with reinforced walls.
One of the most common methods of securing the pressure relieving panels to an enclosure is with explosion venting fasteners. Under normal conditions, the explosion venting fasteners secure the wall panels to the structure and are able to withstand typical loadings such as wind. these fasteners allow the panels to remain in place but are designed to fail when a specific force per fastener is exceeded such as would be the case during an explosion.
