Rationale

Currently there is no ASTM standard for the practice of in-field hydrostatic testing of precast concrete liquid holding structures, typically water tanks composed of one or more assembled sections. References to hydrostatic test methods exist in specific sections of ASTM C969, ASTM C1227 and ASTM C1613, but those procedures are specific to products listed in the scopes of those standards and exclude precast concrete liquid holding structures. This standard establishes exfiltration acceptance testing criteria for all precast concrete structures regardless of shape or number of sections and is based on the criteria in ASTM C969 for circular manholes. This practice is only for structures that are in their final installed positions, precluding the use of this practice at the manufacturing facility prior to delivery.
