Ventilation with outdoor air containing elevated ozone concentrations may complicate remediation attempts. [69] The WHO standard for ozone concentration is 60 μg/m 3 for long-term exposure and 100 μg/m 3 as the maximum average over an 8-hour period. [29] The EPA standard for ozone concentration is 0.07 ppm average over an 8-hour period. [70]
One can use upholstery twist pins (a flat-headed corkscrew-like pin) to effect a temporary repair, but repairs usually involve tacking or replacing the entire headliner. Heat, humidity, and time rapidly degrade the bond that the polyurethane foam has with the face fabric. As the foam oxidizes and yellows, the fabric-foam bond fails.

Everflex is a British fabric used as a roof covering on cars, and is a type of vinyl roof. Everflex was used on both hardtops and convertibles. Its usage was popular from the 1960s to the 1980s [1] on luxury cars. [2] Though its popularity has greatly decreased for new vehicles, it is still manufactured as a material used to restore vehicles.
Ozone attack will occur at the most sensitive zones in a seal, especially sharp corners where the strain is greatest when the seal is flexing in use. The corners represent stress concentrations, so the tension is at a maximum when the diaphragm of the seal is bent under air pressure. Close-up of ozone crack (using ESEM) in NBR diaphragm seal
