2. Testing and Certification

Phase 2 confirms that the project has a credible testing and certification pathway for AS/NZS 4234 modelling, AS/NZS 2712 certification, and scheme applications.

Residential SWH projects usually require evidence across potable water, electrical safety, collector performance, tank heat loss, annual simulation, and certification. EnergyAE completes the AS/NZS 4234 modelling, but the client, test lab, and certification body usually provide the other evidence.

In this section

• Potable Water and Plumbing
• Electrical Safety
• Collector Performance (AS/NZS 2535.1)
• Tank Heat Loss (AS/NZS 4692)
• AS/NZS 4234
• Certification

Phase sub-tasks

1. Confirm what testing has already been completed.
2. Confirm the lab and certification body for any testing/certification still underway.
3. Sanity-check collector performance (AS/NZS 2535.1) and tank heat loss (AS/NZS 4692) reports before modelling.
4. Confirm AS/NZS 2712, Electrical Certification & EESS registration status.
5. Record missing evidence in the project checklist and client follow-up list.

Testing overview

Test	Standard	Purpose
Potable water	AS 3498, AS 4020	Confirms materials and potable water safety evidence for certification and scheme files
Electrical safety	AS/NZS 60335 series, CISPR, IEC 61000 series	Confirms electrical safety and EMC evidence
Collector performance	AS/NZS 2535.1 or EN 12975	Supports solar collector efficiency inputs for AS/NZS 4234 modelling
Tank heat loss	AS/NZS 4692.1 Appendix C	Supports tank heat loss inputs and certification
Annual simulation	AS/NZS 4234	Calculates annual energy performance and certificate values
Certification	AS/NZS 2712, EESS	Supports product certification and scheme eligibility

Exit gate

Phase 2 exits when required test reports and certification evidence are received or tracked with clear owners, due dates, and project risk notes.

The next phase is Phase 3 - Documentation Review.
