- Prevalence of visible foam degradation (EU and JPN): None of the assessed devices from Europe or Japan showed significant visible degradation.
- Volatile Organic Compounds (VOCs): VOC emissions are below established limits based on ISO 18562-3
- New devices and used devices (including used devices with visible foam degradation) were tested and were all found to be compliant with ISO 18562-2 allowable limits for PM emissions.
- Philips have provided a list of devices already fully tested and those at various stages of testing which can be found via the link (web site)
- Philips are continuing with the device recall, repair and replacement program at this time.
