For years, designers have been specifying an f'm equal to 1500 psi with Type S mortar using the unit strength method. According to the Code this would require a block compressive strength of 1900 psi. Recently on projects, some designers are now specifying a higher f'm, i.e., 2000 psi, 2500 psi and 3000 psi with Type S mortar.
