The IP64 rating tells you exactly what an industrial enclosure can handle: complete dust protection and resistance to splashing water from any angle. For equipment operating in processing plants, chemical facilities, or outdoor installations, this combination matters. Dust infiltration causes failures. Water causes corrosion and shorts. IP64 addresses both.
What IP64 Actually Means in Industrial Settings
The Ingress Protection rating system, defined by IEC 60559, classifies how well mechanical casings and electrical enclosures resist solids and liquids. An IP64 rating breaks down into two components. The first digit, ‘6’, represents the highest level of solid particle protection—no dust enters the enclosure. The second digit, ‘4’, indicates resistance to splashing water from any direction.
This dual protection serves manufacturing plants, chemical processing facilities, and mining operations where fine particulates and water exposure occur regularly. Fine dust can cause equipment malfunction or create hazardous conditions. Splashing water from rain, washdowns, or accidental spills leads to short circuits and corrosion. In projects like Tilenga, where WAROM supplied explosion-proof lighting and electrical systems, this level of dust and water resistance proved essential for operational integrity and safety.
Understanding these specific components helps engineers and project managers select appropriate equipment for their operational needs. Proper selection prevents premature equipment failure and reduces maintenance costs.
| IP Code Digit | Protection Against Solids | Protection Against Liquids |
|---|---|---|
| 0 | No protection | No protection |
| 1 | >50 mm | Dripping water |
| 2 | >12.5 mm | Dripping water (15° tilt) |
| 3 | >2.5 mm | Spraying water |
| 4 | >1.0 mm | Splashing water |
| 5 | Dust protected | Water jets |
| 6 | Dust tight | Powerful water jets |
How IP64 Testing Actually Works
Achieving an IP64 rating requires adherence to stringent testing protocols. These tests validate the environmental sealing capabilities of industrial enclosures. WAROM’s commitment to quality shows in our explosion-proof systems, as demonstrated in projects like the General Paint safety upgrade, where rigorous testing ensures reliable device protection.
The testing process involves two distinct phases: dust ingress protection and water spray protection. Both methodologies are standardized under IEC 60529, providing a consistent framework for evaluation. Manufacturers must prove their equipment can withstand these conditions without compromising functionality or safety.
For dust protection, enclosures undergo an IP6X dust protection test. The device sits in a sealed chamber filled with fine talcum powder. A vacuum pump creates negative pressure within the enclosure, simulating operational conditions that might draw dust inward. The device remains in this environment for a specified duration, typically eight hours, or until a certain volume of air has passed through. After the test, inspectors examine the enclosure’s interior for any dust penetration. No dust means the ‘6’ rating holds.
The water resistance aspect gets verified through an IPX4 water spray test. This test exposes the enclosure to splashing water from all directions. Specialized spray nozzles deliver water at a specified flow rate and pressure, ensuring uniform coverage. The device rotates to expose all surfaces to the spray for at least 10 minutes. Following this, the enclosure gets inspected for any water ingress that could affect internal components. Successful completion confirms the ‘4’ rating. These testing procedures are critical for certifying equipment used in demanding industrial settings.
What specific tests determine an IP64 rating for industrial devices?
An IP64 rating for industrial devices comes from two primary tests: the IP6X dust ingress test and the IPX4 water spray test. The dust test exposes the device to a fine talcum powder atmosphere under negative pressure for several hours. This verifies that no dust can penetrate the enclosure. The water test subjects the device to splashing water from all directions for a minimum of 10 minutes. This confirms protection against water spray, safeguarding internal components. Both tests are required for industrial device certification and IP rating verification, confirming the device’s ability to withstand harsh environmental conditions.

Why IP64 Matters for Equipment Lifespan and Safety
The IP64 rating extends beyond compliance. It directly impacts device longevity and operational safety in harsh industrial environments. Equipment with this rating withstands continuous exposure to dust and splashing water—common culprits for premature wear and failure. This robust protection translates into reduced maintenance costs and fewer unplanned downtimes.
In the Fushilai Pharmaceutical CM/CDMO construction project, WAROM supplied explosion-proof equipment, including distribution boxes for critical areas. These devices required high levels of ingress protection to ensure reliable operation in a pharmaceutical environment where cleanliness and protection against contaminants are paramount. The IP66 rating on many of our products, such as the BHD91 Series Explosion-proof Junction Boxes and the BXJ8050 Series Terminal Boxes, ensures superior protection, contributing to extended device lifespan and consistent performance. This commitment to robust design minimizes the need for frequent repairs or replacements.
IP64 compliance also enhances operational safety standards significantly. Preventing dust and water ingress reduces the risk of electrical faults, short circuits, and potential explosions in hazardous areas. This proves especially critical in industries dealing with flammable materials or explosive atmospheres. The explosion-proof certification benefits from such ratings are undeniable, as they ensure equipment functions safely even under adverse conditions.
By investing in IP64-rated equipment, companies safeguard their assets and protect their personnel. This proactive approach to industrial equipment reliability mitigates risks and ensures continuous, safe operation. The long-term benefits include financial savings from reduced maintenance, improved safety records, and compliance with stringent regulatory requirements.
How does an IP64 rating compare to other common IP ratings for harsh environments?
An IP64 rating offers strong protection against dust and splashing water, making it suitable for many industrial settings. It provides less liquid protection than higher ratings like IP65 or IP66. An IP65 rating adds protection against water jets, while IP66 safeguards against powerful water jets. For environments requiring submersion protection, IP67 or IP68 are necessary. Compared to IP54, IP64 offers superior dust protection (dust-tight vs. dust-protected). Understanding these distinctions helps when selecting appropriate industrial protection levels and environmental resistance ratings for specific applications.
