Category 1 (annual)
Yearly functional tests of safety devices, such as limit switches, door devices, emergency operation and, for hydraulics, relief valve and pressure checks. Combined with the routine inspection, it is the basis for annual certificate renewal.
Category 3 (three-year, hydraulic)
A three-year test that applies to certain hydraulic elevators, such as systems with cylinders that cannot be visually inspected. It verifies the hydraulic system holds pressure without leaking.
Category 5 (five-year, traction)
A full-load test of car and counterweight safeties, governors and buffers on traction elevators, performed with certified test weights. It takes longer than an annual test, so it is usually scheduled together with the annual inspection.
Who does what on test day
- Elevator company technician: performs the tests
- Certified elevator inspector: inspects, witnesses and records results, then files the report
- Fire alarm vendor: activates detectors for firefighters' recall tests
- Generator vendor: transfers to emergency power for standby power tests, where applicable
Frequently asked questions
Do hydraulic elevators need a five-year test?
No. The Category 5 full-load test applies to traction (electric) elevators. Hydraulic elevators have annual Category 1 tests and, for certain systems, a three-year Category 3 test.
