Test Results


First-rate anti-slip protection is required for a successful safety program. Fortunately, anti-slip effectiveness is not left to chance, but verified by independent laboratories. Review our performance on a variety of parameters below.

Independent Testing Results

Coefficient of Friction (COF) is the measure of a product’s ability to provide safe traction and thereby prevent slips-and-falls.

Prior to 2006, ASTM International published standards for testing COF. Those standards were withdrawn because they referenced specific devices, the Brungraber Mark II and the English XL VIT. Although these are the most well-known and reliable devices for measuring COF, ASTM standards are meant to be neutral in regard to brand names. ASTM International now publishes F2508-11, the Standard Practice for Validation and Calibration of Walkway Tribometers Using Reference Surfaces, which contains evaluation criteria used to certify reliable testing devices. Both the Brungraber and the English devices have attained this certification.

We Exceed OSHA and ADA Standards

When SAFEGUARD® products were tested for Coefficient of Friction using the Brungraber Mark II testing device, the results showed a COF value nearly double OSHA’s 0.5 guideline and far exceeding the ADA’s recommended value of 0.6. Even when angled as an ADA access ramp, and in wet or oily conditions, our anti-slip surface greatly exceeds these guidelines.

Safeguard’s covers more than double the coefficient of friction requirement for OSHA and ADA
Results from Safeguard® Hi-Traction and HiGlo-Traction Covers tested on the Brungraber Mark II. Similar results were obtained using the English XL VIT.

Testing was performed on samples of both SAFEGUARD® Hi-Traction and SAFEGUARD® HiGlo-Traction samples.

Test Procedure

ASTM D4587 – Conducting Tests on Paint and Related Coatings and Materials Using a Fluorescent UV-Condensation Light- and Water-Exposure Apparatus

The method is a cyclic test comprised of 4 hours of exposure to ultraviolet light with the test specimens at 60°C followed by 4 hours of water condensation on the test specimens at 50°C. The fluorescent lamps closely simulate noon summer sunlight.

Test Results

The test period totaled 200 hours, approximately equivalent to 5 years normal exposure. The following changes took place:

Measurement of lightness/darkness (L*) small change
Tendency towards decreasing redness and increasing greenness (a*) small decrease
Tendency towards increasing yellowness (b*) slightly larger increase
Luminescence Retention (HiGlo-Traction Cover) 100% after 158 hours
90% after 200 hours
(slight yellowing of the epoxy)
Photoluminescent Test Conditions
Product Excitation 4500K Fluorescent Light
Excitation Duration 2 Hours
Illuminance on Surface 2 Footcandles (21.6 lux)
Minimum Brightness Rating Required
30.0 mcd/m2 at 10 minutes
7.0 mcd/m2 at 60 minutes
5.0 mcd/m2 at 90 minutes

mcd/m2 = millicandelas per square meter
