Explanatory Note

This Equivalency Certificate authorizes the handling, offering for transport and transport of tubes in a manner that does not comply with Part 5 of the Transportation of Dangerous Goods Regulations. The tubes are interconnected by a manifold and assembled within a framework. Such an assembly of tubes is typically known as a multiple-element gas container. The certificate holder has demonstrated that when used and tested under the stipulated conditions, the tubes could be used with an equivalent level of safety.

An extension of the tube service life up to a maximum of 20 years might be considered upon the submission by the certificate holder, (i.e. the cylinder manufacturer) of supporting data and test reports pertaining to these tubes from the time of manufacture and from the time in service.

NOTE

Under Canadian Law, a foreign manufacturer of non-specification means of containment cannot be charged with an offence under the Transportation of Dangerous Goods Act, 1992 for failure to comply with the conditions of an Equivalency Certificate. However, certain remedies under the Act are available to Transport Canada in this eventuality.

These include:

1. detention of dangerous goods and consequently the means of containment containing them (subsection 17(1));

2. detention of the means of containment whether full or empty (subsection 17(1));

3. directions not to import the means of containment or to return them to origin
(subsection 17(3));

4. inspectors' directions (section 19);

5. directions to importers of the means of containment to issue notices of defective construction or recall (subsection 9(2)); and

6. revocation of the equivalency certificate, thereby making any use of the means of containment an offence (subsection 31(6)).

If none of the foregoing are adequate, Protective Directions may be issued to prohibit or to control the use of the means of containment (section 32).

The bonfire test shall be designed to demonstrate that finished tubes while mounted within their transport framework, and complete with the fire protection system (tube valves, pressure relief devices and/or integral thermal insulation) specified in the design, will prevent the rupture of the tubes when tested under the specified fire conditions.

Precautions shall be taken during fire testing in the event that tube rupture occurs.

1.2 Tube set-up

One representative container consisting of a quantity of tubes containing the maximum quantity of gas to be vented per single pressure-relief manifold within the container design shall be placed on a support structure approximately 300 mm above the fire source.

Metallic shielding shall be used to prevent direct flame impingement on tube valves, fittings, and/or pressure relief devices. The metallic shielding shall not be in direct contact with the specified fire protection system (pressure relief devices or tube valves).

Any failure during the test of a valve, fitting or tubing that is not part of the intended protection system for the design shall invalidate the result.

1.3 Fire source

A uniform fire source of at least 0.6 m in length shall provide direct flame impingement on the tube or transport container surface.

Any fuel may be used for the fire source provided it supplies uniform heat sufficient to maintain the specified tube temperatures until the tubes are vented. The selection of a fuel should take into consideration air pollution concerns. The arrangement of the fire shall be recorded in sufficient detail to ensure that the rate of heat input to the tubes is reproducible.

Any failure or inconsistency of the fire source during a test shall invalidate the result.

d) the pressure shall be released, the fluid shall be drained, and the interior of the tube shall be dried,

e) the pressure in the tube shall be cycled for 5 cycles, between 10% of service pressure and service pressure, with air, nitrogen, or the intended lading. During each cycle, the pressure shall be held at the upper cyclic pressure for at least 2 hours,

f) following the high pressure hold of the final cycle, the gas shall be released freely to the atmosphere, and

g) the cylinder shall then be subjected to a leak test.

3.2 Acceptable results

Following the above test sequence, the tube shall be sectioned and the liner and liner/end boss interface shall be inspected and not show evidence of any deterioration, such as fatigue cracking or electrostatic discharge.

4. Environmental Fluids Test

4.1 Container Set-Up and Preparation

A shorter tube with smaller diameter may be used as an alternative to a full-scale tube. The shorter tube shall be manufactured with the same process, materials, general wrapping pattern, shall have the same stress level as the full-scale production tube at test pressure, and shall have a length-to-diameter ratio not less than 2.5.

One tube shall be tested, including coating if applicable.The upper section of the tube shall be divided into five distinct areas and marked for pendulum impact preconditioning and fluid exposure. The areas shall be nominally 100 mm (4 in.) in diameter. The areas may not be oriented along a single line, but shall not overlap. Although preconditioning and other fluid exposure is performed on the cylindrical section of the tube, all of the tube, including the domed sections, shall be as resistant to the exposure environments as the exposed areas.

4.2 Pendulum Impact Preconditioning

The impact body shall be of steel and have the shape of a pyramid with equilateral triangle faces and a square base, the summit and the edges being rounded to a radius of 3 mm (0.12 in.). The center of percussion of the pendulum shall coincide with the center of gravity of the pyramid; its distance from the axis of rotation of the pendulum shall be 1000 mm (39.37 in.). The total mass of the pendulum referred to its center of percussion shall be 15 kg (33 lbs.). The energy of the pendulum at the moment of impact shall be not less than 30 Nm (22.1 ft‑lb) and as close to that value as possible. During pendulum impact, the tube shall be held in position by the end bosses. Each of the five areas shall be preconditioned by impact of the pendulum body summit at the center of the area. The tube shall be unpressurized during preconditioning.

4.3 Environmental Fluids for Exposure

Each marked area shall be exposed to one of five solutions.

The five solutions are:

Sulfuric acid - 19 percent solution by volume in water.

A pad of glass wool approximately 0.5 mm (1/64 in.) thick and between 90 and 100 mm (3.5 and 4.0 in.) in diameter shall be placed on the exposure area. A sufficient amount of the test fluid shall be applied to the glass wool to ensure that the pad is wetted evenly across its surface and through its thickness for the duration of the test, and to ensure that the concentration of the fluid is not changed significantly during the duration of the test.

4.4 Pressure Cycle and Pressure Hold

The tube shall be hydraulically pressure cycled between less than or equal to

10 percent of service pressure and 130 percent of service pressure for a total of 3000 cycles. The maximum pressurization rate shall be 27.5 bar (400 psi) per second. After pressure cycling, the tube shall be pressurized to 130 percent of service pressure, and held at that pressure a minimum of 24 hours and until the elapsed exposure time (pressure cycling and pressure hold) to the environmental fluids equals 48 hours.

Notes

1. For a new design of a cylinder with water volume larger than 450 L, a minimum of 1 cylinder may be used for each design change. For a change of boss-liner interface column, a leak check of the liner interface would be accepted. The pneumatic cycle test is not required if the boss-liner interface does not change.

a. Where the design variant's burst pressure to test pressure ratio is over 20% greater than the same ratio for the approved design.

b. When length increases up to 50% and/or diameter increases up to 20%, Bonfire test may not be required if the volume stays the same or decreases and the same PRD system is used.

2. Test to be conducted for reduction in diameter only.
