Let’s dive into the important aspects of measuring Dynamic Coefficient of Friction (DCOF) accurately. DCOF is a crucial measure of the resistance between two surfaces in relative motion, quantifying the frictional force that opposes the motion of an object. Understanding DCOF is essential as it provides valuable information about slip resistance under dynamic conditions. In this article, we will explore the do’s and don’ts of measuring DCOF and highlight the significance of using standardized testing methods and equipment.

DCOF and Its Importance

DCOF serves as the primary measurement for slip resistance in the United States, recognized by prominent standards development organizations like ANSI (American National Standards Institute) and ASTM (American Society for Testing and Materials). Here’s why DCOF is crucial:

1. DCOF provides a realistic representation of slip resistance:
   • The DCOF accurately measures the friction between a moving foot and a surface, making it a reliable indicator of slip resistance during dynamic activities such as walking or running.
2. DCOF is practical and easy to measure:
   • Portable standardized testing equipment like the BOT-3000E and approved test methods such as ANSI A137.1 for laboratory settings or A326.3 for field testing make DCOF measurement practical and straightforward.
3. DCOF ensures consistency and comparability:
   • Utilizing DCOF as a standard enables consistent and comparable measurements across various surfaces and locations. This establishes a baseline for slip resistance, facilitating meaningful comparisons between different flooring materials, coatings, or surface treatments.
4. DCOF aligns with industry research and testing methods:
   • By using DCOF as a standard, the aim is to ensure that surfaces offer sufficient friction to minimize the risk of slips and falls, particularly in areas prone to wet or contaminated surfaces.

Proper Measurement of DCOF

To measure DCOF accurately, it is crucial to use a device specifically designed for this purpose, such as the BOT-3000E Tribometer. Other tribometers like the pendulum tester are not suitable for measuring DCOF, as they were primarily designed for determining breaking distances on roads and calculating Pendulum Test Values (PTVs) rather than measuring dynamic coefficient of friction.

Here are some essential considerations when measuring DCOF using the BOT-3000E Tribometer:

1. Device calibration:
   • Ensure that the device is properly calibrated to maintain accurate measurements.
2. Trained and certified operators:
   • The operator of the BOT-3000E should be trained in using the device and hold professional certification in slip testing.
3. Standard test methods:
   • The operator must follow a standard test method for measuring slip resistance to ensure consistency and accuracy.
4. Wet conditions and SLS Solution:
   • Testing under wet conditions using SLS (Sodium Lauryl Sulfate) Solution is essential for comprehensive slip resistance assessment.
5. SBR Rubber sensor:
   • The operator should use an SBR Rubber sensor that is appropriately reconditioned according to standard requirements.
6. Approved ANSI reference surface:
   • It is important to use an approved ANSI reference surface during testing.

Common Mistakes and Examples

To avoid common pitfalls in slip testing, here are a few examples of what not to do when using the BOT-3000E Tribometer:

1. Improper distribution of SLS Solution:
   • Avoid using a spray bottle to distribute SLS Solution onto a substrate. Standard test methods require even distribution using a brush.
2. Incorrect positioning of the BOT-3000E:
   • Ensure that enough SLS Solution is distributed evenly, and the BOT-3000E is correctly positioned to measure the contaminated surface. Incorrect starting positions will yield inaccurate DCOF measurements.
