B05 SPRAYING OR ATOMISING IN GENERAL; APPLYING FLUENT MATERIALS TO SURFACES, IN GENERAL
Description
IPC Class B05 covers the fundamental technologies and apparatus for spraying, atomising, and applying liquid or other fluent materials onto surfaces. This encompasses spray guns, atomisers, nozzles, and complete spraying systems used across diverse industries including painting, coating, pesticide application, and industrial finishing. The class includes both the mechanical devices that generate spray patterns and the process methods for controlling fluid delivery and atomisation. Adjacent classes address specific applications (such as agricultural spraying in A01M) or narrower technical aspects covered in subclasses B05B through B05D.
IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
3 shared codes have differing titles between IPC and CPC.
