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.

What is the maximum decibel rating humans can hear at?
1654 decibels an hour
How much energy can a nuclear power plant can produce in an hour?
It depends upon the rating of the plant. A typical plant will produce around 1100 megawatts per hour.
How do you write a sentence with kilowatt?
We pay for the electricity by the kilowatt hour. An energy-efficient lightbulb has a low kilowatt usage rating.
What is the maximum velocity of a falling person?
The maximum velocity of a falling person is about 200 miles per hour; at that point the air resistance does not allow further acceleration.
How fast are the winds of a fire tornado?
It is difficult to determine because, for understandable reasons, nobody has tried to measure them. Winds on a fire whirl can potentially exceed 100 miles per hour.
Is Class 1 fire rating the same as 1 hour fire resistance rating?
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).

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.
What is the fire resistance rating for one-inch thick plate carbon steel?
1 hour
What is Clay brick fire rating?
1 hour for single wythe
Does a 1 hour fire resistant door really only last 20 minutes before it burns up in fire?
No, a 1-hour fire-resistant door is designed to withstand fire for up to 1 hour before failing. The rating indicates the door's ability to resist fire penetration for a specific length of time, not that it will fail after 20 minutes.
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.
Safety issue of chemical anchor bolt?
Epcon chemical anchors have a 4 hour fire rating unlike others.
Is it an eight hour class or a eight hour class?
It is an eight hour class
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.....
How do you build a fire rated wall?
A fire rated wall is rated as such because of the material used in construction. There is specific drywall board and rated doors to obtain a fire rating. The standards are 2 and 4 hour ratings unless referring to electrical equipment.
Builtin cabinet from family room into garage what is the best fire rated 2-4 door to use to seal off cabinet?
A hollow metal exterior door should give you a one hour fire rating.
Is there such thing as ice resistance?
yes Ice contain a lot of friction, enough to even set something on fire if a car is rubbing on it at 85,000 miles per hour.
Define each ISO building class 1 through 6?
ISO 1 - Frame Construction (Wood walls & Roof, foundation construction does not matter) Masonry Veneer or accents still count as ISO 1. ISO 2 - Joisted Masonry - Free standing Masonry shell with wood floors and joists, flammable roof. (If structure burns, masonry walls remain) ISO 3 - Light noncombustible - Structure does not add to fire (fuel) load of building, but does not resist fire well. Light steel construction. ISO 4 - Masonry Noncombustible - Free standing masonry walls with noncombustible floors and roof. ISO 5 - Modified Fire resistive - Walls between fire devisions in structure have 1 hour fire rating. Noncombustible structure. ISO 6 - Fire Resistive - Walls between fire devisions have 2 hour fire rating, otherwise noncombustible structure.
