Case Study: a major sports stadium identifies escalator failure cause with Envista Forensics FTIR analysis

a major sports stadium identifies escalator failure cause in just a few years with Envista Forensics

The customer, a major sports stadium, faced premature cracking and failure of its escalator stairs just a few years after construction. They engaged the vendor, Envista Forensics, whose experts in the Materials Lab used Fourier-transform infrared (FTIR) spectroscopy analysis to investigate the cause.

Envista Forensics determined that the failures were caused by Environmental Stress Cracking, which was exacerbated by a chemical used to clean the escalators. The FTIR analysis proved that the cleaning agent initiated the stress relief, leading to the premature cracking. This finding identified the root cause of the failure for the customer.
