Hydrostatic pressure test: energy sources and direct controls

A hydrostatic test pressurises pipework with water to prove integrity before service.

High-energy check

Treat every pressure test as high energy. This tool does not calculate pressure energy. Stored energy remains until verified depressurised.

This task's main energy sources are not calculated by this tool. Use the trigger checks below and competent-person verification.

Trigger checks

Pressure
Compressed gas, liquid, hydraulic, pneumatic or vacuum energy.

Direct controls to verify

Ticks stay on this screen only. Nothing is saved or sent.

Test boundary is defined and physically verified.
Exclusion is in place during pressurisation and while under pressure.
Pressurisation is authorised and controlled by a named person.
Gauges are calibrated and visible from outside the exclusion.
Depressurisation is verified before any joint is broken.
Stop if pressure behaves unexpectedly or a leak appears.

For your SPA or pre-start

State the test pressure and boundary, the exclusion during pressurisation, who authorises pressure changes and how depressurisation is verified.

Limitations: This tool supports planning and verification only. It does not replace competent risk assessment, legal duties, employer procedures, client requirements or competent supervision.
