Affiliated Engineering Laboratories, Inc. has developed special equipment for use in field testing of surfaces to determine the coefficient of friction between a given fixed field surface and appropriate applied surfaces, such as rubber tires, leather shoes, etc. Tests are made to determine adequacy and safety of surfaces for activities such as pedestrian foot traffic or automotive accident reconstruction evaluations dependent upon coefficient of friction measurements. These techniques may be applied to numerous other applications where quantitative evaluation of the frictional nature of a surface is required.

Typical field surfaces requiring coefficient of friction evaluation include
parking lots, sidewalks, road pavements, dance floors, vestibules, stair
treads, bathtubs, shower rooms and other synthetic surfaces.

In addition, other special testing can be conducted using a James Tester or
Brun apparatus in accordance with accepted American Society for Testing and Materials standard tests when necessary for particular applications.

Laboratory equipment has also been developed for evaluating the
effectiveness of non-slip tile, mats, waxes and other protective coatings.

Typical laboratory tests for slipperiness would include footwear, wax
samples, paints and painted surfaces in various stages of dryness. Tipping
angles of objects prone to sliding such as tabletop appliances are also
analytically determined.
