Comparative Analysis of Slip Resistance Test Methods for Granite Floors.

Area of Science:

• Materials Science
• Civil Engineering
• Building Safety

Background:

• Assessing floor slip resistance is critical for preventing accidents.
• Standardized testing methods are essential for reliable product classification.
• Variability in testing can lead to inaccurate safety assessments.

Purpose of the Study:

• To compare three distinct methods for testing floor slip resistance.
• To evaluate the correlation and precision of different slip resistance indices.
• To analyze how testing methodology influences the final slip resistance classification.

Main Methods:

• Comparison of the shod ramp test (acceptance angle, αob), slip resistance value (SRV), and sliding friction coefficient (μ).
• Testing on granite slabs with varying surface finishes (polished, flamed, brushed, grained).
• Analysis of inter-method correlation, precision, and classification outcomes.

Main Results:

• Slip resistance classification is highly dependent on the chosen test method.
• Low-roughness surfaces showed the most significant variation in classification based on the test.
• Discrepancies between methods can lead to inadequate risk assessment.

Conclusions:

• The selection of a slip resistance test method directly influences product classification.
• Inconsistent classifications pose risks to the safe use of building facilities.
• Further research may be needed to harmonize slip resistance testing standards.
