A new independent study published through the Kyungnam University, in the Republic of Korea, confirms that the “safety criteria” for the B101.1 standard.  The objective of the study was to determine whether subjective measurement of slipperiness could be used as a subsidiary mean which made up for the demerit of indicators (roughness and coefficient of friction) of slipperiness.

The study offered the following conclusion:

This study was to determine whether subjective measurement of slipperiness could be used as subsidiary means which made up for the demerit of indicators (roughness and coefficient of friction) of slipperiness. This study showed that perceived slipperiness had a potential to assess floor slip risk. The major findings of this study are as follows:

  1. The perception rating obtained with the AHP exhibited a high correlation with the Friedman test (r = 0.96).
  2. The perception rating obtained with the Friedman test exhibited a high correlation with the SCOF obtained by the BOT-3000 (r = 0.96), except for the polished tile floor.
  3. The perception rating obtained with the Friedman test exhibited a high correlation with the COF obtained by the Ramp test (r = 0.99), except for the ground steel plate
  4. The safety criteria obtained in this study were similar to those of ANSI/NFSI B101.1 and much higher than HSL UKSRG Ramp test.
