PERIODIC LEAK TEST AND INSPECTION FOR ROAD VAULT TANK
(IBC)
IMPORTANT: The tank owner / user(s) are fully responsible for the testing and re-certification
of these tanks.
As per Transport Canada Regulations and CGSB-43.146 code guidelines,
all code 31A IBCs intended for the shipment of
liquid dangerous goods must be leak tested and inspected by a facility holding a ‘Certificate of Registration to Leak Test and
Inspect Intermediate Bulk Containers’ within 60 months of the original date of manufacture, and every 60 months
or less thereafter.
Exception: IBC’s <= 450L may be exempt from periodic leak testing provided they meet the requirements of
exemption 1.33. See link below for additional info. It is the responsibility of the tank owner / user to ensure
compliance with any TDG regulations.

Procedure for Leak Test
Leak test shall be conducted on each container by applying air at a gauge pressure of not less than 20 kPa (3 PSI; 0.20 bar)
for at least ten minutes. Do not exceed 25 kPa (3.5 PSI; 0.30 bar). The leak-tightness of the container shall be
determined by a suitable method such as coating the seams and joints with a soapy solution, air pressure differential or
immersion of the container in water. In the latter case, a correction factor shall be applied for the hydrostatic pressure.
Vented closures shall either be replaced by similar non-vented closures or the vent shall be sealed during testing.
While under the test pressure, each container shall be visually inspected for leakage, defective fittings, welds or closures,
structural components, significant gouges or other defects. Non-integral gaskets for threaded closures shall be replaced with
new gaskets equivalent in performance to the original and suitable for the intended use.
Criteria for Passing Leak Test and Inspection
There shall be no leakage of air from any IBC. Any container displaying leakage or defects listed above that could render the
container unsafe for the transportation of dangerous goods shall not qualify for dangerous goods service. Such containers
shall have any specification marks removed or obliterated and the container identified as unfit for the use of dangerous
goods service, unless the container is repaired or refurbished and passes the leak test and inspection.
Marking
On each IBC tank, Westeel provides a location and/or decal where inspection marking is to be recorded. The letter "R", the
date [MM/YY] of the latest successful leak test / inspection, and the Transport Canada Certificate number of the leak tester
shall be permanently and clearly marked within this allocated area or decal.
Leak Test and Inspection Records
A record of all containers leak tested and inspected shall be kept by the test facility
and the owner of the container until
the next leak test / inspection or for at least 60 months from the date of the last test. The record shall include the type of
container, owner's name and address, test date, tank serial number, and the test facility's address and certificate number.
