Explanatory Note

This Equivalency Certificate authorizes the manufacture and use of welded steel cylinders based on the requirements for Specification TC-4BAM cylinders set out in CSA B339-08, with reduced wall thickness. The certificate holder has demonstrated that by restricting design parameters, augmenting testing at time of design qualification and at time of production, and by limiting the types of gases contained therein, the cylinders could be used with equivalent safety.

NOTE

Under Canadian Law, a foreign manufacturer of non-specification cylinders cannot be charged with an offence under the Transportation of Dangerous Goods Act, 1992 for failure to comply with the conditions of a 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. 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 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).

APPENDIX A

The specified impact energy and striking velocity must be achieved by striking the representative cylinder with a moving striker or by dropping the cylinder from an appropriate height.

The impact energy, F, must be determined by:

F = 30M

where:

F = energy, in Joules,

M = maximum gross mass of cylinder (tare of cylinder plus maximum permitted mass of the intended lading), in kg

The striking velocity must be between 7 m/s and 8 m/s.

On completion of both impacts, the cylinders must be visually examined for signs of damage and assessed against the condemnation criteria specified in Table 1 of Appendix B of this certificate. If both cylinders show damage exceeding the condemnation limit, then on completion of both impacts, both cylinders must be subjected to a burst test in accordance with Clause 4.14.5 of CSA B339-08. If the cylinders withstand any of the impacts with visible damage equal to or below the condemnation limit, then on completion of both impacts, one cylinder must be subjected to the burst test in accordance with Clause 4.14.5 of CSA B339-08 and the other must be subjected to the pressure-cycling test in accordance with Clause 4.14.4 of CSA B339-08, except that pressurization must be performed for 12,000 cycles.

The tests must be repeated with two additional cylinders, which have been pressurised to at least 1.5 x service pressure. After each impact, the pressurised cylinders must not leak.

2. EDGE IMPACT TEST

Two representative unpressurised cylinders must each be impacted with an angle iron with the edge parallel to the cylinder axis (see Figure 2).

3 DROP TEST ON FLAT SURFACE

Two representative cylinders must be filled with water or an inert solid material, or both, to a mass equivalent to the maximum gross mass (tare of cylinder plus maximum permitted mass of the intended lading) and pressurised to the test pressure/1.2.

The cylinders must then each be dropped twice onto a flat surface from 1.2 m, in each of the five different orientations illustrated in Figure 5, i.e. ten drops per cylinder.

FIGURE 5 - Orientations for 1.2 m drop onto flat surface

The surface must consist of a steel plate, 10 mm thick, sufficiently flat so that the difference between any two points on the surface is no more than 2 mm. It must be replaced if the surface no longer meets this requirement. The plate must rest on a flat, smooth concrete bed, at least 100 mm thick. The plate must be in full contact with the concrete so that it is fully supported.

After completion of all ten drops, one cylinder must be subjected to a pressure-cycling test in accordance with Clause 4.14.4 of CSA B339-08, except that pressurization must be performed for 12,000 cycles, and the other must be subjected to the burst test in accordance with Clause 4.14.5 of CSA B339-08.

4. DROP TEST ON ANGLE IRON

Two representative cylinders must be filled with water or an inert solid material, or both, to a mass equivalent to the maximum gross mass (tare of cylinder plus maximum permitted mass of the intended lading) and pressurised to the test pressure/1.2.

The cylinders must then each be dropped twice onto an angle iron as shown in Figure 3 from 1.2 m, in each of the five different orientations illustrated in Figure 5, i.e. ten drops per cylinder.
