Overview
The ICC Dynamic Friction Tester (ICC DFT™, formerly known as NAC DFT) is an aerodynamic tow-behind continuous friction measurement device (CFME), approved by the FAA for use on airport runways. Built in the United States and used by airport authorities worldwide, the latest ICC DFT design updates focus on what matters most in real-world runway operations: stable tracking and long, uninterrupted testing. Our updated design features a widened body to improve stability during turns and transitions, and increased water capacity to extend continuous wet testing—helping crews cover more runway and taxiway with fewer stops. The result is steadier towing, smoother tracking during collection and transport, and fewer refill interruptions so teams can stay focused on consistent data collection and safe operations.
Benefits
Aerodynamic Design
The ICC-DFT™ features an aerodynamic tow-behind design, ensuring accurate and consistent measurements during operation.
FAA Approval
Approved by the Federal Aviation Administration (FAA), the ICC-DFT™ complies with rigorous standards, attesting to its reliability and suitability for use on airport runways.
ASTM E2340 Compliance
The device adheres to the ASTM E2340 standard, a recognized method for measuring the skid resistance of pavements using a continuous reading, fixed-slip technique.
Year-Round Functionality
Designed to operate effectively in both summer and winter conditions, the ICC-DFT™ provides comprehensive friction data, crucial for maintaining safe runway conditions.
Contaminant Identification
The device helps identify and assess various contaminants, including rubber deposits, dust particles, jet fuel, oil spillage, water, snow, ice, and slush, which can impact runway friction.
Continuous and Real-Time Data
The ICC-DFT™ continuously collects reliable friction values and displays the results graphically in real-time, offering immediate insights into runway conditions.
Data Transmission
The collected data is transmitted via direct serial cable to a tow vehicle laptop or tablet, ensuring efficient and timely data transfer.
Comprehensive Friction Parameters
The device calculates key friction parameters such as Mu or RCR values, and data can be displayed in an easy-to-read bar chart for specific runway sections.
Portable and Self-Contained
With its self-contained design, the ICC-DFT™ is portable and can be easily moved to different locations for friction measurements, contributing to its versatility and ease of use.
Built-to-Last Design
Engineered with state-of-the-art precision, the ICC-DFT™ features a durable and environmentally friendly design that significantly reduces maintenance and operating expenses.
