Frequently Asked Questions

What does the IP69K rating signify?

IP69K is the highest standard on the Ingress Protection (IP) rating scale, designed for products regularly exposed to high-pressure and high-temperature washdowns.

What are IP69K products designed for?

IP69K products are designed for applications requiring sanitation and cleanliness, where products are regularly exposed to high-pressure and high-temperature washdowns.

What are common applications for IP69K products?

IP69K products are ideal for food and beverage, wastewater, pharmaceutical, marine, medical facilities, and medical equipment manufacturing applications.

What testing is performed for IP69K certification?

Products are dust-tight tested in an Arizona A2 Dust chamber. They also undergo high-pressure steam jet cleaning with water sprays of 1160–1450 psi at 176°F (80°C).

What other certifications do Federal Signal products have?

Federal Signal products meet or exceed standards from UL, CSA, CSFM, IECEx, and other global certifications, in addition to IP69K.

Does Federal Signal offer a wide range of IP69K products?

Yes, Federal Signal offers over 700 models of IP69K products. These are available for safe area, hazardous, and explosion-proof applications.

What are the benefits of using IP69K products?

IP69K products reduce failures from water/dust ingress. This increases productivity and decreases production downtime.

How does IP69K differ from NEMA Type 4?

IP69K protects from close-range, powerful, high-temperature water jets and is dust-tight. NEMA Type 4 involves high volume, low pressure water from a long distance.
