Values for fire-resisting walls are provided in ACI 216.1-07 ratings in between 1 to 4 hours. Please go through it for details.
ACI 216.1 -07 describes rating for 1hour, 1.5 hours, 2 hours, 4 hours.
You can also refer IS 3089:1979 for values of fire-resisting for a different structure and dimensions.

Making of 1hr and 2hr firing wall:
This is one of the most popular questions.
Basically, building codes typically require that the structure is wall roof floor, the roof is fire-resistant.
The standards set forth by the International Building Code (IBC). fire resistant Wallis designed for a definite time period.
According to ‘Commercial drafting and detailing book’, a one of our fire rated wall consists 2 x 4 studs spaced 16 inches from the centre of one stud to the centre of the next.
