Significant changes were made to the UPC and UMC, IAPMO says.
The 2009 editions of the
Uniform Plumbing Code (UPC) and
Uniform
Mechanical Code (UMC), published by the International
Association of Plumbing and Mechanical Officials, have been tentatively
scheduled for release March 1, 2009, completing a three-year consensus development
cycle accredited by the American National Standards Institute.
Significant
changes to the UPC
include:
- New
requirements for the installation of nonwater urinals
- Specific
prescriptive requirements for the installation of temperature limiting devices
for various fixtures
- New requirements for the distribution
of hot water for bathing, washing, laundry, cooking, dishwashing, etc.
- Updates
and revises the identification of potable and nonpotable water systems
- New
requirements for sizing Hydromechanical grease interceptors and gravity grease
interceptors
- Complete modification and new requirements for
greywater and reclaimed water systems
- Three new tables for
ease of use, including approved materials, devices and their respective
referenced standards for water supply and distribution piping and drain, waste
and vent piping and backflow prevention devices, assemblies and methods
Significant
changes to the UMC
include:
- New
requirements for outdoor air ventilation updated in accordance with ASHRAE
62.1-2007
- New requirements for the protection of mechanical
equipment against flood damage
- 69 new refrigerants added to
Table 11-1, Refrigerants Groups, Properties and Allowable Quantities
- For
hydronic systems, three approved referenced standards for piping materials and
installation
- New joining method for fuel gas tubing
utilizing press-connect fittings in accordance with CSA LC-4
- New
prescriptive and performance-based requirements for listed and unlisted open
flame decorative appliances
The Uniform Codes
are developed using the American National Standard Institute's consensus
development procedures. This process brings together volunteers representing a
variety of viewpoints and interests to achieve consensus on plumbing and
mechanical practices.
The codes are
designed to provide consumers with safe and sanitary plumbing and mechanical
systems while, at the same time, allowing latitude for innovation and new technologies.
The public at large is encouraged and invited to participate in IAPMO’s open
consensus code development process. A code development timeline and other
relevant information are available at IAPMO’s Website,
www.iapmo.org.
