Office Chair Destructive Testing

Office chair destructive testing mainly includes seat impact testing, chair base rotational life destructive testing, and related destructive testing in the Australian office chair impact testing AS/NZS standard, as detailed below:

Seat Impact Testing: An office chair seat impact tester is used, with a 57kg sandbag placed on the seat and dropped from a height of 30mm for 100,000 round-trip impacts. This test aims to check whether the seat will show signs of damage, collapse, or structural loosening after long-term exposure to impact forces, ensuring the stability and durability of the seat during daily use.

Chair Base Rotational Life Destructive Testing: The rotational mechanism of the chair base is a core component, and its durability directly affects the user experience and safety. Testing is conducted using a rotational life tester, which consists of a loading system, a rotational drive system, a counting and recording system, and a safety protection system. During testing, a continuous load is applied, and the base is rotated repeatedly to observe whether the base structure shows signs of deformation, cracking, abnormal noise, or functional failure. Testing methods include constant load testing, alternating load testing, environmental simulation testing, and combined stress testing, among others. Common failure modes include bearing failure, structural fracture, loosening of connecting parts, material deformation, and surface wear.

Destructive Testing in the Australian Office Chair Impact Testing AS/NZS Standard: This includes strength testing of the base and five-star feet, simulating multiple free-fall impacts from a specified height with a specified weight at different positions on the seat, and applying static pressure to the five-star feet; strength and durability testing of the chair back, with durability testing conducted for tens of thousands of cycles and strength testing applying forces much greater than normal use; downward pressure and lateral torsion testing of the armrests, simulating vertical and lateral forces; and durability testing of the casters and chair legs, with the chair simulating daily movements such as moving and turning on a test platform for tens of thousands of cycles.
