For electrical elements (e.g. digital displays, heating systems, initiators) EN 60204-1:2018 shall be
applied.
NOTE For use in explosive atmosphere, see further information in 4.5.
4.3 Temperature
Protection against burns from contact with hot surfaces shall be ensured by thermal insulation of
touchable elements of the application equipment, which can be reached during normal operation.
Hand-held application equipment shall be designed to prevent the surface temperature of handle and

NOTE 1 The main source of noise are turbulences due to different speed of air and coating material needed for
the atomization process. Noise reduction is not possible without negative influence on the atomization process.
When designing application equipment for coating materials, the information and technical measures to
control noise at the source given in EN ISO 11688-1:2009 shall be taken into account (see 6.2.1. c)).
