Code Development Process - USEHC/USPSHTC 


IAPMO’s code development process is an open consensus process accredited by the American National Standards Institute (ANSI).  The process invites the participation of the IAPMO members and the general public.  Anyone may participate by attending committee meetings, proposing changes to the Uniform Swimming Pool, Spa and Hot Tub Code and Uniform Solar Energy & Hydronics Code. The procedures which govern the code development process are known as the Regulations Governing Consensus Development.

The USPSHTC and USEHC are developed under a three-year cycle.  The first major step in the process is the Call for Proposals. During this period, anyone may submit a proposed code change to the current edition of the Uniform Swimming Pool, Spa and Hot Tub Code and Uniform Solar Energy & Hydronics Code.  During the first meeting scheduled in year two of the cycle, the Swimming Pool Technical Committee and Solar Energy & Hydronics Technical Committee reviews all proposed changes to the codes.  Shortly after their meeting, the committees are balloted on whether to accept, amend or reject the proposed code changes.  Such actions are printed and made available to the public in the Report on Proposals.

Following the publication of the Report on Proposals, IAPMO members and other interested parties have the opportunity to appeal to the IAPMO Executive Committee with regard to procedural or substantive matters.

Thereafter, the Comments are submitted to the Technical Committees along with all other public comments during the Call for Comments period. At their meeting in year three of the code development cycle, the Technical Committees review and act on all comments. The committee’s actions are published in the Report on Comments.

The IAPMO consensus code development process is open to anyone who has an interest in Swimming Pool, Spa & Hot Tub and Solar Energy & Hydronics systems.  IAPMO members have a voice and a vote throughout the entire process.
