||New Specification Provides Guidance on Installation and Materials
for Central-Vacuum Tubes and Fittings
Embedded in house walls, central-vacuum tubes and fittings connect
wall receptacles to a remote power unit in the home. Users attach
a portable hose to the wall to access high-powered cleaning in
ASTM F 2158, Standard Specification for Residential Central-Vacuum Tube and
Fittings offers an installation guide and material specification
for tubes and fittings used in central-vacuum systems.
The tubing goes through the walls the same way as a plumbing
system, said ASTM member Ralph Guinn, an air-electronics technologist
who helped develop F 2158. There are a lot of central-vacuum
products out there that can be made to any specific standard and
may, in fact, fail in the field because of substandard material
being used, he averred.
ASTM approved the standard on Dec. 10, 2001. At the moment, there
is no marking on this product to show that its made to any accepted
standard, said Guinn, manager of Quality Assurance for Canplas
Industries, Ltd., Barrie, Ontario, Canada. The specification,
of course, will allow that to happen. The vacuum-cleaning industry
also wants to standardize the tube and fittings to be assured
that they are getting a consistent quality, he added.
Subcommittee F17.25 on Vinyl Based Pipe will maintain Standard
F 2158, which was initiated by ASTM Committee F11 on Vacuum Cleaners. Manufacturers, engineers, users, installers,
consultants, and retailers in both groups collaborated on its
development. What we have done is develop this standard so that
it can be recognized in national and international uniform mechanical
codes, he explained.
According to Guinn, homeowners can reference F 2158 for installation
of central vacuum systems. Building and mechanical inspectors
can use it to determine if tube and fitting installations meet
the ASTM standard.
