IPX4IPX8

IPX4IPX8 is a designation that appears to combine two different Ingress Protection (IP) ratings. The Ingress Protection rating system, also known as IP ratings, is used to classify the degree of protection provided by mechanical casings and electrical enclosures against intrusion from solid objects and liquids. The first digit of an IP rating refers to protection against solid objects, while the second digit refers to protection against liquids.

An IPX4 rating indicates that the enclosure is protected against splashes of water from any direction. The "X" signifies that there is no specific rating for solid particle ingress, or that this aspect was not tested or is not relevant for the product's intended use.

An IPX8 rating indicates that the enclosure is protected against continuous immersion in water under conditions specified by the manufacturer. This generally implies a higher level of water resistance than IPX4, suggesting the ability to withstand submersion for extended periods and at specific depths. Again, the "X" indicates no specific rating for solid particle ingress.

The combined designation IPX4IPX8 is unusual. It is possible that a product might be certified to meet both standards independently, or it could be a misunderstanding or a non-standard labeling convention. A product might be tested and found to meet IPX4 for splash resistance and IPX8 for immersion resistance, and both ratings are communicated. However, typically, a product would be assigned a single, highest applicable IP rating. Without further context or specific product information, it is difficult to definitively explain the meaning of "IPX4IPX8." It is recommended to consult the product's official documentation for precise details on its ingress protection.
