IEC 60529 is the internationally recognized standard used to classify the degree of protection provided by enclosures against the ingress of solid objects and water. It defines the Ingress Protection (IP) rating system, covering protection against dust and solid particle ingress from IP1X to IP6X, as well as protection against water ingress from IPX1 to IPX8.

Compliance with IEC 60529 helps manufacturers demonstrate the durability, reliability, and environmental resistance of their products in various operating conditions.
