STANDARDISATION. 



MESH OF WIRE CLOTH. 



The following table of " I.M.M. Standard Laboratory Screens " is intended for use in making grading tests 

 and for the correlation of screens used in commercial or other work. 



When screens other than the I.M.M. Standards are employed, the diameters of apertures should be given 

 in any published results, so that comparisons may be made. 



When screens are described simply by the number of meshes per linear inch, it will be understood that the 

 I M.M. Standard is referred to.
