1) Object with 90% remission (based on standard white, DIN 5033).

2) Average service life: 50,000 h at TU = +25 °C.

3) Difference between standard/washdown and hygiene: The essential difference between a standard/washdown product and a hygiene product is that where the process and contact with the medium (activity in the vicinity of the food) are concerned, a hygiene product is designed in accordance with the latest standards and hygiene design guidelines, and materials are selected accordingly.
