Prep

C2. PREPARATION

C2.1 Cleaning — Prior to being leak tested or inspected, the IBC shall be

1. thoroughly drained of all previous ladings;

2. interior washed to remove previous ladings;

3. interior rinsed to remove washing materials;

4. interior dried to remove liquids; and

5. exterior washed to remove previous ladings, foreign material, labels and adhesives from all exterior components

of the IBC.

C2.2 Vents — Vents or vented closures of the IBC shall be replaced by similar non-vented closures, fastened in the

closed position, or removed and their openings plugged during the leak test.

Leak Test

C3.1 General — A leak test shall be conducted on an IBC that is used to transport liquids, other than a mobile IBC.

C3.2 Pressure — An air or liquid pressure equal to or greater than 20 kPa shall be applied to the body or inner receptacle

of the IBC. The pressure shall be held for at least 10 min.

C3.3 Procedure — The IBC shall be observed for leakage during the test period by any effective means such as coating

the seams, joints and flange seals of the IBC with a soapy solution or by submersing the IBC in water and observing

for bubbles or by measuring a drop in air or liquid pressure. In the case of water submersion or hydraulic pressure,

the test pressure may be adjusted to take into account the hydrostatic pressure.

C3.4 Results — Testing of the IBC in accordance with par. C3.3 shall not result in the leakage of air or liquid from the

IBC.

Inspection

C4. INSPECTION

C4.1 General — An inspection shall be conducted on an IBC that is used to transport liquids.

CAN/CGSB-43.146-2002 C1

C4.2 Procedure

a. The inspection shall be conducted on the IBC, other than a mobile IBC, while pressure is being applied. In the

case of a composite IBC, the inner receptacle shall be removed from the outer casing and pressure applied while

the inspection is being conducted.

b. The fittings, closures, structural components, vents, valves, pumps, lids and gaskets of the IBC shall be visually

inspected for 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.

c. A metal IBC and the metal outer casing of a composite IBC shall be visually inspected internally and externally

for dents, defective welds, corrosion and loss of protective coating.

d. A rigid plastic IBC, and the inner receptacle and the plastic outer casing of a composite IBC, shall be visually

inspected internally and externally for excessive crazing, cracks, swelling, gouges, permanent deformation and

degradation from ultraviolet light.

C4.3 Results — Inspection of the IBC in accordance with par. C4.1 and C4.2 shall show no defects that could render the

IBC unsafe for transporting dangerous goods. An IBC having defects shall be repaired, re-inspected and, for an IBC

other than a mobile IBC, leak tested or have any specification marks removed or obliterated and the container

identified as unfit for use for dangerous goods service.

Refurbishing

C5.1 Original Specification — If a standardized IBC is repaired or replacement parts are installed on the IBC, the repairs

and replacement parts shall be of the same specification as the original unless otherwise permitted by the applicable

standard.

C5.2 Specification Mark — If the specification marking on an IBC is obliterated in the refurbishing process, the marking

shall be reproduced in permanent form on the IBC.

C5.3 Inner Receptacle of a Composite IBC — If the plastic inner receptacle of a compositestandardized IBC is

replaced, the replacement receptacle shall be an unused receptacle of the same specification as the original. If

unused receptacles of the same specification are no longer manufactured, an unused receptacle of a design that is

comparable to and has the same outer dimensions as the original receptacle shall be used.

C5.4 Non-standardized Composite IBC — The replacement for an inner receptacle of a non-standardized composite

IBC shall be unused, shall be of a comparable design and shall have the same outer dimensions as the original

receptacle. If the replacement inner receptacle for a non-standardized composite IBC displays a UN Standard IBC

Code, the code shall be removed or obliterated.

Marking

C6. MARKING

C6.1 General — An IBC that has been successfully leak tested and inspected shall be marked with the letter “R,”

followed by the month and year of the leak test and inspection, followed by the Transport Canada Certificate of

Registration Number of the leak test facility. The mark shall be durable and legible and should be placed on a

securely attached, corrosion-resistant plate on the body or, in the case of a composite IBC, on the outer casing. The

markings shall be readily accessible for inspection.

C6.2 Inner Receptacle of Composite IBC — The inner plastic receptacle of a composite IBC shall display the marking

in par. C6.1 that is permanent and readily accessible for inspection.

Records

C7. LEAK TEST AND INSPECTION RECORDS

C7.1 Retention and Content — Every successful leak test and inspection of an IBC shall be recorded, and a copy of the

record shall be retained by the person in charge of the leak test and inspection facility and by the owner of the IBC

until the next leak test and inspection. The minimum retention period for such records is thirty months. The record

shall include the type of container, the owner’s name and address, the date of the leak test and inspection, the serial

number of the IBC, the name, address and Certificate of Registration Number of the leak test and inspection facility,

and the results of the leak test and inspection.
