In short, No - in the UK "Class 1" is a form of performance that indicates how easily something burns ('Class 4" being the worst).
Fire resistance on the other hand is a term that relates to a construction's ability to resist the passage of fire (e.g. a wall, floor, door etc).
The fact that a material is "Class 1" doesn't necessarily have any bearing on its fire resistance performance. For example, PVC cladding can be obtained to a 'Class 1' rating, but it wouldn't contribute much to the wall's fire resistance performance at all.

Is class 1 fire rating the same as 1 hour fire resistance?

What is class b and c fire code for doors?
Class B and Class C fire codes for doors refer to their fire-resistance ratings as defined by the National Fire Protection Association (NFPA). Class B doors typically have a fire-resistance rating of 1 hour, suitable for use in areas requiring moderate fire protection, while Class C doors have a lower rating, often around 30 minutes, used in less critical applications. These classifications help ensure safety by determining how long a door can withstand fire exposure before failing. Compliance with these codes is essential for building safety and insurance requirements.
Does a 1 hour fire resistant door really only last 20 minutes before it burns up in fire?
No. A fire resistance rating is determined by the amount of time a partition will prevent the spread of fire, so a one-hour door (and its wall and supports) would have to hold back a typical fire growing for at least one hour. For example, a 20-minute fire rating requires a fire door to withstand an intense fire on one side, rising to over 1,400 degrees F during twenty minutes, and then being hit by a pressurized fire stream, without causing any openings.

What is the fire rating of 5/8 type x gypsum board?

Why can a 90 minute fire door be installed in a 2 hour rated wall?
A 90-minute fire door can be installed in a 2-hour rated wall because it provides a level of protection that is still acceptable within the overall fire-resistance rating of the wall. The wall itself is designed to withstand fire for a longer duration, and the door's rating complements this by offering a significant barrier to fire and smoke for a shorter period. Building codes allow for this combination to ensure safety while also accommodating practical considerations such as accessibility and cost. However, it is essential that the installation adheres to specific guidelines and standards to maintain overall fire safety.
When are 90 minute fire rated doors required?
90 minute doors are required when building code requires a 90 minute or 2 hour assembly rating. For example, with IBC '06, 715.4, if a 2 hour wall is required, you can have a 90 minute door. The fire resistance rating depends on the type of building occupancy and component. For example, for fire barrier assemblies or horizontal assemblies, for occupancy of type A (Assembly), B (Business), E, F-2, H-4, H-5, I, M (Merchantile), R, S-2, the fire rating is 2 hours. For other types, say U (Utility) the rating is 1 hour and for H-1 and H-2 (High Hazard) its 4 hours. Since the issue is complex, consult an architect to determine a specific application.
What is considered a 1 hour rated dwelling separation for apartments?
A 1-hour rated dwelling separation for apartments refers to a fire-resistance rating that ensures walls, floors, or ceilings can withstand fire exposure for at least one hour. This separation is designed to limit the spread of fire between units, providing occupants with additional time to escape and allowing firefighters to manage the situation more effectively. Typically, this involves the use of fire-rated materials and construction methods in the building design. Compliance with local building codes and standards is essential to meet these fire safety requirements.

What is the fire rating of concrete?
12" is a good rule of thumb for 2-hour rating....but the 2006 IBC will give you a more accurate indication, plus industry web sites for concrete vendors will give you more accurate info.....
