* The specifications above with a Sieve Opening number in the far left column are not the recommended test sieve specifications regarding the wire diameter although the screen opening does comply with the specified Sieve opening according to tolerances permitted for the average openings.
These specifications should be considered for enhanced production purposes as the open areas are larger than the standard ISO Sieve specifications.
