Pre-Commissioning Tests Every Building Owner Should Demand

An elevator can appear to be in perfect condition yet may not function properly. The light works, the doors slide well, and the ride is pleasant, but the elevator’s braking system has not been tested. The elevator pre-commissioning tests prior to its commissioning are just the proof. As an owner, you have every right to ask for such proof, given that these tests are essential. In case you are still in the planning stage, start with our elevator planning checklist for new construction projects. In half of the cases, the completion tests can be successful only when the shaft and the machine room are properly arranged.

Demand the Test Reports, Not Just the Licence

Legal documents certify that an inspection was done on a specific day. The reports of the tests specify what was being done by the elevator. It is necessary to ask for the original elevator commissioning test reports containing the results, and while using tick boxes in your report you commented that the task was completed, the number and every test were carried out successfully and recorded as well.

Elevator Safety Device Testing Comes Before Everything Else

Elevator safety device testing proves the components that act when something goes wrong, which is exactly why these tests cannot be simulated on paper. Insist on witnessing, or at least receiving records for, each of these:

• The testing of safety equipment, where the equipment grips the rails of the guide and brings the lift to a halt
• Checking the emergency stop of the governor at the rated tripping speed
• Every floor of the building is tested for interlock malfunctioning
• The buffer is tested in a pit
• The operation of the emergency signal device, intercom and rescue equipment is checked in the event of power failure

It is our firm belief at Jet Lifts that carrying out the interlock check at each landing is an absolute must. A lifting machine which can travel when an entrance door is open has the most hazardous defect in the industry.

Elevator Load Testing Proves the Brake, Not the Brochure

Elevator load testing places 125 per cent of the rated load in the car to prove the brake can hold and stop an overloaded lift. The machine carries the load through full travel, and the brake must hold the car stationary with that same load. This is the test building owners skip most often because arranging test weights takes effort. Do not skip it.

Elevator performance testing rides on the same loaded runs: speed against the rated figure, levelling accuracy at every floor, and ride comfort through the full travel. Levelling matters more than most owners realise. A car that stops even slightly proud of the floor is a trip hazard for elderly users and a barrier for wheelchair users, which is why we treat it as a core check on lifts installed for enabling mobility.

Elevator Electrical Testing and Functional Testing Round Out the Machine

Elevator electrical testing checks what no ride can reveal: insulation resistance of the wiring, earth continuity to every metal part a passenger might touch, phase sequence, and protection settings on the main supply. These readings go into the report as numbers. Keep them, because your maintenance contractor will compare against them for years.

Elevator functional testing then runs the lift as passengers will use it. Every call button, every door reversal device, the overload warning, the fan and light, the fireman’s switch where fitted. On hydraulic units, this stage adds a pressure check and a drift test, which reveals whether the cylinder holds the car steady overnight. If your building uses a hydraulic system, ask specifically for the drift test record, because a leaking cylinder shows up there long before it shows up as a breakdown.

Elevator Compliance Testing Ties the Machine to the Law

Elevator compliance testing confirms that the elevator has been installed as per the approved drawings and the relevant Indian Standard, which is IS 17900 in case of new installations. In Gujarat and other states embracing the Lift Act, the record substantiates the Form B application, while the Inspector of Lifts completes the prerequisite elevator safety testing prior to issuance of the operating permit.

Elevator acceptance testing is your side of the same process. You or your consultant watch the commissioning run against an agreed elevator inspection checklist and only sign it after everything in it is passed. Never take a word for “all done” for it. The checklist signed upon acceptance is the document to be used if a dispute arises.

Conclusion

The pattern across all of these checks is simple: demand readings, witness the dangerous-failure tests, and sign an elevator inspection checklist rather than a handshake. An owner who asks for the safety gear, load and interlock records by name changes how seriously the installer treats the commissioning stage.

If you want elevator pre-commissioning tests run and documented properly, talk to Jet Lifts. We test with the owner present and hand over every reading on paper.

Frequently Asked Questions

1. What Are Elevator Pre-Commissioning Tests?

Elevator pre-commissioning tests are the documented checks carried out after installation and before the lift carries passengers. They cover safety devices, load and brake performance, electrical safety and functional operation, and they produce the records used for statutory inspection and licensing.

2. How Much Load Is Used in Elevator Load Testing?

The purpose of elevator load testing is to confirm that brakes are capable of controlling an overloaded car by applying 125% of the rated load. Then various performance checks such as speed and levelling are conducted, keeping the rated load in the elevator.

3. Is Elevator Acceptance Testing Mandatory in India?

The statutory inspection takes place in states where the Lift Act is enacted: the Inspector of Lifts carries out the inspection before the working license is given. Elevator acceptance testing is not necessary to be carried out by an owner according to the law. However, to keep yourself safe, consider that this procedure is necessary for your project.

4. What Does Elevator Electrical Testing Check?

What the elevator electrical testing procedure does is measure insulation, earth continuity, phase sequence, and supply protection settings. All results obtained are presented as readings, which are then recorded for the purpose of future comparison by the maintenance team in the course of elevator operation.
