Slip Resistance Measurement Equipment
Slipmeter Laboratory Testing and Field Slipperiness Surveys
Last updated December
William English, Inc.
has the most elaborate tribometry facilities and field test equipment for
evaluation of traction properties of various flooring materials and shoe
products under a wide range of real-world conditions. I do laboratory
testing here in my shop or field
surveys at your location. My testers have high validity on dry or wet
- Floor Testing
- The English
XL slipmeter, measures the slipperiness of any walking
surface and is recognized by ASTM/ANSI F1679, ANSI A1264.2,
and other specialized test standards
for its use by ASTM, NFPA and ANSI committees as well as OSHA and ADA
compliance. It is also the slipmeter of choice among US insurance companies,
and it is widly accepted in the courts.
Incidence Tribometer is engineered like no other slipmeter in
the world. Besides its unsurpassed validity, it is the lightest-weight
and most easily portable slip resistance tester available. With a weight
of less than four pounds and an overall length of about 12 inches, it can
even be carried aboard an airliner with ease. (For those of you on the
metric system, it is lighter than your laptop and will fit in a breadbox.)
Since dry surfaces are not normally slippery, the XL was
designed primarily for valid measurement on wet surfaces, incorporating
dynamics that mimic certain parameters of a pedestrian's gait. It is the
only slipmeter equipped with a stair fixture that enables the metering
of traction on step nosings parallel to the direction of pedestrian travel.
William English, Inc. also performs laboratory testing
of floor samples as well as conducting field surveys and consulting
with clients concerning remediation measures for slipperiness under foot.

The Real-World Shoe Traction Tester
- The English
XST shoe traction tester applies actual shoes to any
test surface under any contaminated condition, utilizing dynamics that
mimic certain parameters of the human foot's action in walking. The XST
can also be used in the field to test any shoe under prevailing
conditions on actual workplace floors. It has been the only whole-shoe
tester that can beat sticktion.
(before the SST). Laboratory services are available to rank any
number of shoe products in order of traction performance, thereby enabling
industrial safety managers to select the best-performing shoes for employees
in hazardous environments. The XST is for lab testing service
and field consulting only and is not for sale.
- Other Specialized Testing Equipment
is available for evaluating traction performance of specialized
sport shoes, crutch and cane tips in the presence of lubricating contaminants,
and other custom equipment can be developed for unusual applications,
or I can modify my standard equipment to meet your particular need.
The SST Specialized Shoe Traction
tester, a mobile device for applying realistic dynamic loads, thrust
vectors and velocities to specialized shoes on actual indoor or outdoor
surfaces, including turf, was designed and built here and was used for
laboratory testing of special-purpose shoes having traction performance
above 1.0, the prototype of this cutting edge tester has been sold to the
International Tennis Federation in England. An improved version has been
constructed and has been sold to eXceL
