If a company does not test for dust protection, they replace the first digit with an "X" (e.g., IPX7 or IPX8).
An rating is an advanced, hybrid hardware standard used to confirm that a device possesses absolute waterproof and dustproof capabilities under extreme environmental stress. In modern industrial manufacturing, marine engineering, and rugged consumer electronics, hardware verification ensures that equipment can survive conditions where standard consumer tech would instantly fail.
In the world of rugged electronics and industrial equipment, we are all familiar with standard ratings like IP67 or IP68. However, a specific term has been surfacing in technical datasheets and specialized hardware circles: .
When a rating begins with , it means the manufacturer skipped testing the device for solid particle entry (dust) to focus entirely on water certification.
