The different criteria for achieving fire resistance in a building include preventing smoke leakage, providing insulation, increasing load bearing capacity for your construction material, and much more.

Yes it is, but they are slightly different. In order to standardize both fire curves, in 1975 the International Standards Organization issued the ISO 834 "Fire-Resistance Tests -- Elements of Building Construction", to became the worldwide standard fire curve.

Fire ratings are don't by Underwriters Laboratories (UL). They are and independent firm whose work is accepted by fire protection agencies.
The fire protection class for 70301 typically refers to the fire resistance rating of a specific building or structural element as defined by building codes. This rating assesses how well a material can withstand fire exposure and is often categorized into classes, with higher numbers indicating better fire resistance. The specific class can vary based on the materials used and the intended use of the structure. For accurate and detailed information, it's best to consult local building codes or fire safety regulations.
The highest fire resistance rating typically required by building codes is a 3-hour rating, which applies to certain structural elements in high-rise buildings, assembly occupancies, and other critical structures. This rating indicates that a component can withstand fire exposure for three hours while maintaining its structural integrity. Specific requirements may vary depending on local codes and building use, so it's essential to consult the applicable building regulations.
The fire rating of 2mm galvanized steel typically does not have a specific fire rating in terms of hours like building materials such as gypsum board. Instead, steel can withstand high temperatures, but it loses strength as it heats up. Generally, the fire resistance of steel structures is improved through insulation or fireproofing measures. For specific applications, it's advisable to consult relevant building codes or fire safety standards to determine the appropriate fire resistance requirements.
A firewall is a structural barrier designed to prevent the spread of fire between different sections of a building, providing a high level of fire resistance and often extending from the foundation to the roof. In contrast, a fire barrier smoke limiting wall primarily aims to limit the passage of smoke and hot gases, while still offering some level of fire resistance, but not to the same extent as a firewall. Fire barriers can be used to compartmentalize spaces for smoke control, whereas firewalls are meant to safeguard against fire propagation.
Fire retardant drywall offers several benefits in buildings, including increased fire resistance, improved safety for occupants, reduced spread of flames, and compliance with building codes and regulations.
The Standard temperature-time curve ISO 834, also known as the Cellulosic curve and/or the standard nominal fire curve, is used to test the fire resistance of materials subjected to a category "A" fire hazard i.e. with the fire hazard rating based on the burning rate of general combustible building materials and building contents. The ISO 834 is the least "intensive" of the fire curves.
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.
