What is NFSI Certification?

The NFSI performs slip-resistance testing that takes wet, real-world conditions into account. The rigorous certification process includes tests that demonstrate:

Slip resistance when the flooring is wet.
Slip resistance when a person is standing still and walking.
Slip resistance not only on a sample in a laboratory, but also on an actual installation in the field.
