Schedule Import test clearance for UNRTDG cylinders

r 5A

1 Purpose of import test clearance

The purpose of an import test clearance is to verify that a cylinder has foreign test markings indicating that the cylinder has been tested in accordance with clause 6.2.2.7 of UNRTDG (and is therefore safe to be filled in New Zealand).

2 Verifying foreign design and construction certification

If the first interval following manufacture specified in regulation 52(1) has not yet passed, a test certifier may issue an import test clearance for the cylinder if the cylinder is marked in accordance with clauses 6.2.2.7.1 to 6.2.2.7.5 of Chapter 6.2 of UNRTDG—

(a)

by or on behalf of the government of a country other than New Zealand; and

(b)

certifying that the cylinder has been designed and constructed, and passed initial inspections and tests, in accordance with Chapter 6.2 of UNRTDG.

3 Verifying foreign periodic testing

If the first interval following manufacture specified in regulation 52(1) has passed, a test certifier may issue an import test clearance for a cylinder if the cylinder is marked in accordance with clause 6.2.2.7 of chapter 6.2 of UNRTDG—

(a)

by or on behalf of the government of a country other than New Zealand; and

(b)

with current periodic inspection and test markings that certify that the cylinder complies with the periodic inspection and testing requirements of clause 6.2.2.4 and 6.2.2.6 of chapter 6.2 of UNRTDG.

4 Issue of import test clearance

If the test certifier issues an import test clearance for a cylinder, he or she must provide the Authority with a copy of the import test clearance.

5 Exception

Despite clauses 2 and 3, a test certifier must not issue an import test clearance for a cylinder if he or she has reasonable grounds to believe that the cylinder—

(a)

is unsafe; or

(b)

despite its markings, does not comply with Chapter 6.2 of UNRTDG.

Clerk of the Executive Council.
