The foam did not carry a fire-resistance rating required by state law.

Motor control centers usually sit on floors, which are often required to have a fire-resistance rating.

An independent ceiling, however, can be constructed such that it has a stand-alone fire-resistance rating.

Different occupancies within one building are separated by a fire barrier with a defined fire-resistance rating.

It is a form of fire-resistance rating.

If critical environmental conditions are not satisfied, an assembly may not be eligible for a fire-resistance rating.

All examples above are also typically required to be bounded by walls and floors that have a fire-resistance rating.

When the installed configuration does not comply with the appropriate certification listing, the fire-resistance rating may be lower than expected.

Applying a certification listed fireproofing system to certain structures allows these to have a fire-resistance rating.

Type X is typically the material chosen to construct walls and ceilings that are required to have a fire-resistance rating.

Increasing by one hour the fire-resistance rating of structural components and assemblies in buildings 420 feet and higher.

The most common ceiling that contributes to fire-resistance ratings in commercial and residential construction is the dropped ceiling.

A fire-resistance rating typically means the duration for which a passive fire protection system can withstand a standard fire resistance test.

Fire testing involves live fire exposures upwards of 1100 C, depending on the fire-resistance rating and duration one is after.

One remedy, that is utilized in industrial settings, is to equip such containers with a measure to provide a fire-resistance rating.

If the building design drawings do not indicate wall fire-resistance ratings, the door schedule may indicate fire door requirements .

Firestop pillows are passive fire protection items, used for firestopping holes in wall or floor assemblies required to have a fire-resistance rating.

Concrete building structures often meet code required fire-resistance ratings, as the concrete thickness over the steel rebar provides sufficient fire resistance.

In ordinary building fires, concrete typically achieves excellent fire-resistance ratings, unless it is too wet, which can cause it to crack and explode.

In this case, an occupancy separation with a two-hour fire-resistance rating may not be able to de-rate its closures, such fire doors or firestops.

The firestop at the perimeter slab edge is considered a continuation of the fire-resistance rating of the floor slab.

The time it takes for the steel element that is being tested to reach the temperature set by the test standard determines the duration of the fire-resistance rating.

Whether or not the building elements forming the joint have a fire-resistance rating, the joint design must still consider the anticipated operational movement of each joint.

Firestop mortars are mortars most typically used to firestop large openings in walls and floors required to have a fire-resistance rating.

These organisations each publish in codes and standards, wall and floor assembly details that can be used with generic, standardised components, to achieve quantified fire-resistance ratings.
