Uniform Mechanical Code

src: backflowpreventionjournal.org

Designated as the United States National Standard, Uniform Mechanical Code (UMC) is a model code developed by the International Association of Pipelines and Mechanical Officers (IAPMO) to manage the installation, inspection and maintenance of HVAC ( Heating, Ventilating and Air-conditioning) and cooling system.

UMC was developed using the American National Standards Institute (ANSI) consensus development procedure. This process brings together volunteers representing different perspectives and interests to reach consensus on mechanical issues.

UMC is designed to provide consumers with secure mechanical systems while, at the same time, allow room for innovation and new technologies. The wider community is encouraged to provide input for the development process. This code is updated every three years.

History

In 1926, a group of Los Angeles pipeline inspectors admitted that there were no uniform requirements for the installation and maintenance of the pipeline system. At that time, the heating is done by a boiler that distributes heat to the radiator. Efficient air conditioning is not available. Very different practices and the use of many different compaction codes, often contradictory, by local jurisdictions lead to inappropriate and potentially harmful pipeline systems. This underscores the need to develop code models that can be applied uniformly across jurisdictions.

Two years later, the city adopted the first version of uniform piping and mechanical code developed by the Los Angeles City Pipeline Inspection Association (LACPIA) and based on input from the pipeline inspectors committee, master plumber and waitresses, and mechanical engineers, assisted by public utility companies and pipe industry.

The final product of this effort, the first Uniform Mechanical Code, published by IAPMO, a new name for LACPIA, was adopted in 1966 when the mechanical scope of work grew out of the pipeline and became more readily available in residential applications.) In 1967 For fifty years lastly, this voluntary code has been adapted by jurisdiction not only throughout the United States, but also internationally. The consensus development process was first implemented in the 2003 edition.

The 2012 edition is the fourth edition developed under the ANSI consensus process. Contribution to the contents of the code is made by each segment of the building industry, including various interests such as consumers, law enforcement authorities, installers/maintainers, insurance, labor, factories, research laboratories/standards/testing, specialists, and users. The Uniform Mechanical Code of the Year 2012 is supported by the American Society of Sanitary Engineering (ASSE), the Association of Mechanical Contractors of America (MCAA), the Association of Heating-Cooling-Pipe-Cooling (PHCC-NA) Contractors, the Unity Association (UA) and the World Plumbing Council (WPC ).
