7、gnificance and Use3.1 Installations of resilient floor tile require tight joints ifsatisfactory appearance is to result.The quality of cut ofresilient tile is determined by this test method.4.Apparatus4.1 Shadow Box,consisting of a backlighted poly(methylmethacrylate)(PMMA)plate measuring 28 by 28 b
8、y38in.(710 by 710 by 9.5 mm).One metal strip,28 in.long by34in.(19 mm)wide by18in.(3.2 mm)thick,and one metal strip,2714in.(692 mm)long by34in.wide by18in.thick,arepermanently attached to the PMMA plate to form an included90 6 10-sec angle at the lower left-hand corner of the PMMAplate.This is suita
9、ble for tiles up to 12 by 12 in.(305 by 305mm).For larger tiles,longer metal strips will have to be used,such that the length of each strip is greater than twice thelongest dimension of the tiles to be measured.4.2 Optical Comparator3Power illuminated magnifier,equipped to measure to the nearest 0.0
