(Specification)Standard Specification for Residential Central-Vacuum Tube and Fittings
Standard Specification for Residential Central-Vacuum Tube and Fittings
ABSTRACT
This specification establishes requirements and test methods for materials, dimensions and tolerances, flattening resistance and impact resistance of plastic tubing and fittings for use in central-vacuum systems for residential buildings. The tube and fittings shall be homogeneous throughout and free of visible cracks, holes, foreign inclusions, or other defects. The tube flattening, tube impact strength, tube dimensions, tube length, and fitting dimensions shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers the establishment of requirements and test methods for materials, dimensions and tolerances, flattening resistance and impact resistance of plastic tubing for use in central-vacuum systems for residential buildings.
1.2 All notes and footnotes shall be considered as nonmandatory requirements of the specification.
1.3 This specification does not apply to: inlet valve mounting plates of fittings directly connected to these plates, reducer fittings, mufflers exhaust vents, or flex tubing attached at the power unit location.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.

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)

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
