Ask X3What does 49 CFR 178.813 (Leakproofness test) require?
Generated guidance. Confirm the source and its applicability before you act. How we check sources.
Based on 49 CFR 178.813, here are the practical requirements for motor-carrier owners:
* When it is required: The leakproofness test must be performed to qualify all Intermediate Bulk Container (IBC) design types, as well as on all production units that are either:
* Intended to contain liquids, or
* Intended to contain solids loaded or discharged under pressure.
* Preparation:
* You must replace vented closures with similar non-vented closures, or seal the vents.
* For metal IBCs, the initial test must be done before you fit any thermal insulation equipment.
* The inner receptacle of a composite IBC can be tested without its outer packaging, as long as the test results are not affected.
* Test Method and Pressure:
* Use air at a gauge pressure of at least 20 kPa (2.9 psig) for a suitable length of time.
* Detect leaks by coating the seams and joints with a soap solution and water, heavy oil, or another suitable method. (Equally effective methods from appendix B or approved by the Associate Administrator may also be used).
* Passing Criterion: There must be zero air leakage from the IBC.
