The test method in ASTM E1155 covers a quantitative method of measuring ﬂoor surface proﬁles to obtain estimates of the ﬂoor’s characteristic FF Flatness and FL Levelness Face Floor Proﬁle numbers (F Numbers).
Table 188.8.131.52-ASTM E1155 method
|Floor surface classification||Specified overall flatness SOF F||Specified overall levelness SOFL|
The F Speed Reader is simply walked along the floor between the start and stop points and the data collected digitally. At the end of a survey run the data is downloaded to a handheld device and then the next run can start. When the whole of the chosen floor area is surveyed the handheld device is then connected to a laptop or PC and the survey data is downloaded to the F Speed Reader program. At the touch of a button the data is analysed, the overall and local F numbers are calculated and a results table produced.
The table illustrated is from ACI 117-10 showing different Ff and Fl classifications
By using the F-Speed Reader, Face Consultants can quickly test your floor to the ASTM E1155 F Number system.
