Explanatory Note

This Equivalency Certificate authorizes the manufacture and use of aluminum-alloy gas cylinders based on specification TC-3ALM using aluminum alloy AA7032 as an alternative to AA6061. AA7032 is internationally recognized as being suitable for the manufacture of aluminum-alloy gas cylinders and the certificate holder has demonstrated by augmenting design qualification and production testing that the cylinders could be used with equivalent safety. This Equivalency Certificate also authorizes the use of cylinders with internal threads other than those in accordance with North American standards as prescribed in CSA B339. The alternative threads are internationally recognized as being suitable for use in gas cylinders of the designs specified herein. An equivalent level of safety is maintained in this respect by requiring that the thread identification be permanently marked on both the cylinder and the valve.

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 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 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).
