Committee Scope and Responsibility
As defined by the Regulations Governing Committee Projects, the Technical Correlating Committee (TCC) is the consensus body responsible for the development and
revision of any document or documents emanating from a Technical Committee Project (such as the Uniform Plumbing, Mechanical, Solar, and Swimming Pool Codes). All
persons wishing to participate on the TCC must complete an application for Technical Committee Membership (see link below), including a resume of qualifications.
Once an application (and resume) has been received by IAPMO, it is forwarded to the Standards Council Secretary for consideration by the Standards Council.
An important function of the Standards Council is to maintain a balance of interest classifications on the TCC.
Those classifications are:
| Manufacturer | | Labor |
| Enforcing Authority | | Installer/Maintainer |
| Research/Standards/Testing Laboratory | | Special Expert |
| Consumer | | User |
Once appointed to the TCC, each member is subject to annual review and reappointment. It is the responsibility of each
member to participate and act in accordance with the Regulations Governing Committee Projects.
The roster (linked above) are divided into three columns: Name, Representation, and Classification. Committee members are
arranged by classification for ease of identification.
For a more detailed explanation of responsibilities of the Technical Correlating Committee, please refer
to Section 3 of the Regulations Governing Committee Projects.
