FAQ’s

Which pressure equipment requires certification in New Zealand?

Pressure equipment that operates under elevated pressure and falls within applicable regulatory or workplace safety requirements may require engineering assessment, certification, or compliance verification before use. Requirements can vary depending on equipment type, pressure rating, and intended application.

What is included in Pressure Vessel Certification?

Certification may include engineering design review, documentation assessment, compliance verification, engineering calculations, technical reporting, and supporting recommendations for safe operation.

Do imported pressure vessels require compliance assessment?

Yes. Imported pressure vessels often require engineering review to verify that their design, construction, and supporting documentation satisfy applicable New Zealand requirements before installation and operation.

What is Pressure Equipment Compliance Testing?

Pressure equipment compliance testing involves evaluating equipment performance, design information, operational parameters, and engineering documentation to confirm that systems are suitable for their intended use and comply with applicable standards.

How long does the certification process take?

Timeframes depend on project complexity, equipment type, documentation availability, and the scope of engineering review required. Simple assessments may be completed relatively quickly, while larger projects typically require more detailed evaluation.
