A portable apparatus for testing the slip resistance of surfaces such as floors and bathtub surfaces operates by applying a load instantaneously to a pad of friction material resting on the surface at a selected angle of attack. An articulated linkage carrying the pad is set at a predetermined angle and the load is substantially instantaneously applied to determine whether the pad slips at the preset angle. Tests may be successivley conducted at different angles of the linkage or a single go, no-go test may be conducted at a datum angle. The articulated linkage is carried on a pivoted frame which moves across a segment plate to establish the predetermined angle. A pawl and tooth type latching system holds the frame relative to the plate at the preset angle.
