RESISTANCE TO CHEMICALS Since the aggressive agents in liquid or gas form can destroy the plastic parts of the lighting fixtures, increased attention must be paid to the selection of the proper materials. The following table will help in this selection. It contains the most frequently used chemicals. More information can be found on our website (www.ibv.hu).

Before selecting the product, please check the chemical environment for the lighting application. The above table re- fers to an ambient temperature of 25°C±10°C. The chemical resistance is only valid if there are no mechanical effects which may cause surface deformation, elongation or evolution of capillary cracks. Legend: +++ resistant ++ limited resistance O not resistant
* Occupational Exposure Limit - . EC (2000)
It is recommended to consult the manufacturer before any product is selected for potentially chemically aggressive applications.
