(Three Step Process)
BUILDING TRUE CONSENSUS
IAPMO gathers the largest assembly of plumbing and mechanical experts in the world at its annual education and business conference, where anyone — members and non-members alike — can have a voice on proposed changes to the code.
The purpose of the IAPMO code development process is to ensure the continued development and maintenance of the Uniform Codes with the following goals in the forefront:
- Effectiveness in preserving the public health, safety, and welfare.
- The timely evaluation and recognition of technological developments pertaining to construction regulations.
- A consensus process, which provides for the open discussion of proposals by all parties who wish to participate.
IAPMO urges its members and other interested parties to get involved in the code development process to ensure that these goals are maintained. Installers, plumbing and mechanical officials, the construction industry, engineers, and manufacturers all benefit from a cooperative effort in developing codes.
