ASTM F2421-19a

4.1 The combination of both dimensional properties and squareness of resilient floor plank is an important consideration because installed flooring may exhibit an objectionable appearance when either or both characteristics deviate from established tolerances. This test method provides a means of determining length and width dimensions along with squareness, by using a single apparatus and procedure.

1.1 This test method establishes the procedures for determination of both dimension (length and width) and squareness of a rectangular resilient floor plank.
