Slip resistance testing was conducted on your supplied samples using the
English XL Variable Incidence Tribometer on July 23-24, 2015.

The samples had a textured surface with small, rounded asperities.

Introduction


Slip resistance is defined in ASTM F1637.95, Practice for Safe Walking Surfaces,
as "The relative force which resists the tendency of the shoe or foot to slide along
the walkway surface. Slip resistance is related to a combination of factors
including the walkway surface, the footwear bottom, and the presence of foreign
material between them."

Based on human ambulation traces from various studies, the required slip
resistance for normal, straight-line, unloaded, human ambulation is in the range
of 0.25 to 0.35. The threshold for safety, commonly accepted at a value of 0.50,
is derived by applying a factor of safety to account for variations in the physiology
and gait dynamics of humans, and footwear. Loaded activities and sloped
walking surfaces increase the required slip resistance and are task-specific.

The English XL Variable Incidence Tribometer mimics certain parameters of
human ambulation to measure slip resistance in a meaningful manner. The
slipmeter uses an actuation cylinder similar to a leg with an ankle joint. The
velocity of contact is similar to that of a walking human. The test foot surface
area is similar to that of a worn heel, and is constructed of Neolite®, which has
similar traction performance to rubber-heeled shoes. The test foot contacts the
surface with the edge and rotates toward flat, squeezing any contaminant film,
and is then free to accelerate, all as in a heel-slip in human ambulation.

Test Procedure

Prior to all testing, the samples were washed with mild dish washing detergent,
thoroughly rinsed, paper-towel-dried, and allowed to air dry completely before
commencing dry testing. Since testing will be in four directions per sample,
North was marked by taping a corner of the sample, (East, South, and West are
inferred).

The English XL VIT and test foot to be used for testing was calibrated according
to ASTM F1679, and the latest manufacturer’s requirements and instructions. All
equipment was paper-towel-dried and allowed to air dry completely.

The test foot used for all testing is the standard Neolite® foot, prepared with 180
grit wet/dry silicon carbide sand paper on a standardized test foot preparation
device (Sander). Test actuation pressure was maintained at 25 psi ± 2 psi. The
environmental and materials temperature was approximately 75 ± 2 degrees
Fahrenheit, and the relative humidity was 50 ± 2 percent.

Dry testing was conducted in all four (4) directions in the 2 inch diameter center
of the sample. The test foot pad was re-prepared after each full dry slip, and all
test foot preparation was conducted off the machine using a standardized test
foot preparation device (Sander). The rear of the English XL VIT was supported
with a tile of similar thickness to the test sample.

Prior to wet testing, the test foot was again calibrated according to ASTM F1679,
and the manufacturer’s requirements and instructions. Wet testing was
conducted in four (4) directions in the 2 inch diameter center of each of the six (6)
samples. An unbroken film of distilled water was maintained on the test surface
between each stroke of the tribometer. The test foot pad was re-prepared after
each set of eight (8) measurements per test location.

Discussion

NFPA 1901 15.7.4 requires 16 tests in 90 degree increments for uniformly
patterned materials.

The dry testing produced consistently high results for all of the samples. Wet
testing produced similarly high results for the samples, with the lowest average of
0.70.

The relative wet slip resistance value of the subject samples for safety of persons
should be approximated by the average of the 16 readings.


Conclusions

NFPA 1901 states that the 16 readings for each ‘uniformly patterned’ sample
should be averaged and reported as the slip resistance of the material. To meet
the NFA 1901 requirements, materials for exterior surfaces and all interior steps
must have a minimum slip resistance of 0.68 when tested with the English XL
VIT. For interior floors, that minimum value is 0.58 when tested with the English
XL VIT.

The slip resistance of the supplied XS-650 samples was characterized as ≥0.77
dry and as ≥0.70 wet, which satisfies the slip resistance requirements of NFPA
1901 15.7.4. When compared to the generally accepted 0.50 threshold value of
slip resistance accepted as safe for normal, straight-line unloaded, human
ambulation on level surfaces, the subject samples would be considered safe
when clean and dry and when wet with water, and are considerably more slip
resistant than wet hard smooth surfaces like polished marble or ice, which are
characterized by slip resistance values of 0.10 to 0.25.

The surface of the subject samples were textured with rounded asperities. The
surface texture clearly enhances the slip resistance of the sample when wet with
water or other contaminants. The extent of slip resistance enhancement is
related to the surface asperities, which must be of sufficient height and
sharpness to penetrate the hydrodynamic squeeze film or other contaminant to
engage the test foot. For example, fresh broom-finished concrete surfaces with
noticeable texture and sharp peaks frequently produce slip resistance values in
excess of 0.75 when wet with water.

One of our most popular exhibits is our reptile building. But being a small zoo, we also have
a small budget so necessary remodeling is very costly. After have a LINE-X bedliner installed

in my truck, I asked to have a quote to spray the floor of our reptile house. The existing epoxy
cannot withstand the 170,000 year visitors the reptile house receives. LINE-X pricing was
competitive and the crew went above and beyond to make sure that everything was properly
prepped and finished to the highest level. I would recommend LINE-X to anyone.
