X3. SOLVENT CEMENT JOINTS
X3.1 TubeCutting—Cutthetubesquarewiththeaxis,using
a fine-tooth handsaw and a miter box. A rotary cutter may be
used if the cutting blades are specifically designed for cutting
plastic tube in such a way as not to raise a burr or ridge (flare)
at the cut end (see Fig. X3.1). Remove all burrs with a
deburring tool, knife, file, or abrasive paper.
X3.2 Dry Fit Test—The solvent cement joint is designed so
that there will generally be interference of the tube wall with
the fitting socket before the tube is fully inserted. Insert the
