1. A slip meter for measurement of surface slip resistance between a test specimen and a test surface, comprising: self-energized magnetic means for generating a linear force; positioning means on which the magnetic means is mounted for establishing contact of the test specimen with the test surface at an angle of incidence while said linear force is transmitted from the magnetic means to the test surface through the test specimen; and load sensing means connected to the test specimen for collecting and recording measurement data in response to said contact established between the test specimen and the test surface corresponding to said surface slip resistance. |
