UL allows either a

calculated approach,

using formula known

as Roark OR Performance test, with

limitations,

Roark is a conservative

approach. Does notrely on backfill forsupport.

12 External Pressure Test

12.1 A tank shall be tested asdescribed in 12.2. The tank shall notimplode or otherwise be damaged.12.2 The empty tank is to be installedin a test pit using the specifiedanchoring system and the specifiedbackfill procedure. The pit is then to befilled with water to such a level that

the tank is submerged to its maximumspecified burial depth. The tank is toremain submerged for 24 hours. Whilethe tank is still submerged, it is to besubjected for 1 minute to a partialinternal vacuum so that the internalpressure on the tank is 5.3 inches of

mercury less than the externalpressure imposed by the hydrostatichead.13 Internal Pressure Test

A tank shall withstand without rupturefor 1 minute to an internal pressure asspecified:10 ft dia or less, 25 psi

Greater than 10 ft, 15 psi
