HYDROSTATIC TEST PRESSURE
REFERENCE: UG-99 STANDARD HYDROSTATIC TEST
LOWEST STRESS RATIO (LSR):
1 UG-99(b)
MINIMUM TEST PRESSURE = 1.5*MAWP*LSR = 263.00 psi
(PER NOTE 33, MAWP MAY BE ASSUMED TO BE THE SAME AS THE DESIGN PRESSURE)
IMPACT TESTING
The slab material, at 5.0 inches nominal thickness, is supplied in the normalized condition.
The slab material is thus classified by curve D in section UCS-66. The governing thickness for
determining whether impact testing is required is 5.0 / 4 = 1.25 inches [UCS-66(a)(3)].
Using 1.25 inches as the minimum thickness, table UCS-66 indicates that impact testing is
required for minimum temperatures less than -21.0 F. The tie bar material impact test exemption
temperature is -55.0 F. Therefore, no impact testing is required for this frame since the
minimum temperature is -20.0 F. (reference: UG-20, UG-84 & UCS-66)
