Accident Investigation Expert Witness On ASTM Standards

In Procedures for Evaluating Bathing Facility Slip and Fall Accidents, accident investigation expert witness Melvin M. Friedlander, P.E. writes:
The American Society for Testing and Materials (ASTM) standards for evaluating the slip resistance of walkway and bathing facility surfaces are accepted, almost universally, by experienced and reliable slip and fall experts in the United States. The protocol for testing bathing facility surfaces is contained in ASTM Designation F 462 that is entitled “Standard Consumer Safety Specification for Slip-Resistant Bathing Facilities” [1].

This standard was published in 1976 by ASTM Task Group 15.03 and was developed specifically for wet, soapy bathing surfaces consisting of either combined bathtub/shower or shower stalls alone and for a test material that resembles the texture of the bottom of the human foot as closely as possible. The standard is based on test results from 50 different bathtub and shower surfaces with such surface materials as porcelain enamel, acrylic, terrazzo, ceramic tile, synthetic castable marble, sheet molding compound, pressed steel, cast iron, and fiber glass reinforced plastic.
