5-Year Elevator Load Test Requirements

Every five years, ASME A17.1 Section 8.11 requires a comprehensive Category 5 inspection and test for every elevator. This is significantly more involved than the annual Category 1 test -- it physically verifies that safety devices work under real-world loading conditions. Building owners who have never been through a Category 5 test are often surprised by the cost, duration, and coordination required.

What the Category 5 Test Involves

The Category 5 test includes everything in an annual Category 1 inspection (visual examination, functional testing, documentation review) plus a series of load tests and safety device tests that can only be performed under loaded conditions.

The inspector brings calibrated test weights or uses a water-weight system to load the elevator car. Your maintenance contractor must be present with tools and the ability to make adjustments if needed. The inspector, not the maintenance technician, directs all testing.

Full Load and Overload Testing

100% rated load test: The elevator car is loaded to its full rated capacity (the weight shown on the data plate in the cab). The elevator is run at full speed in both directions, stopping at multiple floors. The inspector measures car speed, leveling accuracy, and brake performance. The elevator must stop smoothly and level accurately with the full load.

125% rated load test (traction elevators): The car is loaded to 125% of rated capacity. The elevator is not run at full speed with this overload -- instead, the brake is tested to confirm it can hold the car stationary with 125% load. This verifies the brake has adequate margin above normal operating conditions. The car may also be lowered at slow speed to test the governor and safety devices.

Hydraulic elevator pressure test: For hydraulic elevators, the system is pressurized to 150% of working pressure with the car at the top floor. Relief valve operation is verified. The cylinder and piping are inspected for leaks under this elevated pressure.

Safety Devices Tested

Typical Duration

A Category 5 test takes 4 to 8 hours per elevator, depending on the elevator type, speed, number of floors served, and the age and condition of the equipment. Older elevators with outdated components typically take longer because inspectors need more time to evaluate worn parts and may need to run tests multiple times.

For buildings with multiple elevators, plan on one elevator per day. The elevator being tested is completely out of service for the entire duration. In buildings that rely on a single elevator, coordinate with tenants well in advance about the planned outage.

Cost

These costs cover the inspector's time and test equipment. Your maintenance contractor will charge separately for their time on site (typically 4 to 8 hours of technician labor). If the test reveals violations requiring repairs, those repair costs are additional.

Scheduling Tips

Book early: Start coordinating the Category 5 test at least 90 days before your 5-year cycle date. Qualified inspectors with load-testing equipment are in high demand, and scheduling backlogs of 30 to 60 days are common.

Coordinate with your maintenance contractor: Your maintenance contractor must be present during the test. Schedule the test date with both the inspector and the contractor simultaneously. The inspector may refuse to proceed without a qualified technician on site.

Pre-test maintenance: Have your maintenance contractor perform a thorough service visit one to two weeks before the Category 5 test. Address any known issues, check oil levels, adjust brakes, and verify that all safety devices are functioning. Discovering problems during the Category 5 test wastes expensive inspector time and can force a re-test.

Notify tenants and building occupants: The elevator will be unavailable for an entire working day. Provide written notice at least two weeks in advance, with reminders one week and one day before the test. For buildings with a single elevator, consider scheduling the test on a weekend or after business hours.

What Happens If the Elevator Fails

If the elevator fails any portion of the Category 5 test, the inspector documents the specific failures and may issue a violation notice depending on the severity. Minor issues (slightly out-of-specification leveling, marginal oil levels) typically result in a conditional pass with a requirement to correct the items within 30 to 90 days and have the inspector verify the corrections.

Serious failures -- a car safety device that does not engage, a governor that does not trip at the correct speed, or a brake that cannot hold 125% load -- will result in the elevator being taken out of service immediately. It cannot be returned to service until the problem is corrected and the failed test is successfully re-run. Re-testing costs are borne by the building owner, typically at the inspector's standard hourly rate.

The most expensive outcome is discovering during the Category 5 test that major components (car safeties, governor, or ropes) need replacement. These repairs can cost $5,000 to $30,000 or more, and the elevator may be out of service for weeks while parts are ordered and installed. Pre-test maintenance dramatically reduces the likelihood of this scenario.
