For over 30 years, IAPMO’s standards-developing efforts have primarily focused on plumbing product standards. This concentration was primarily due to IAPMO members’ expertise from over 50 years of writing and updating the Uniform Plumbing Code.

Recently, IAPMO’s efforts have broadened to include standards for mechanical products. Drawing on their years of experience, many IAPMO members have also contributed to the development of the Uniform Mechanical Code. Mechanical product standards cover heating, ventilation, cooling and refrigeration system products.

IAPMO also publishes standards covering products used in the Recreational Vehicle and Manufactured Housing Industry called IAPMO Trailer Standards.

The International Association of Plumbing and Mechanical Officials (IAPMO) has a strong cooperative presence in the nation of India and partnered with the Indian Plumbing Association (IPA) to develop a Uniform Plumbing Code for the nation.

The Government of India approved the establishment of IAPMO Plumbing Codes and Standards India Private Limited, to be known as IAPMO-India. IAPMO and the IPA, both members of the World Plumbing Council (WPC), agreed upon a comprehensive plan to work together to establish a model code of plumbing installation and maintenance for all of India, the Uniform Plumbing Code – India. The IPA Code Committee worked with IAPMO staff in creating a document that recognized and utilized proven international concepts, always taking into consideration the proven plumbing practices and customs within India.

IAPMO, the IPA and the Indian Institute of Plumbing (IIP) formed a partnership agreement to provide plumbing training and education throughout India. The agreement identifies four distinct target markets: existing and emerging Engineers, Plumbing Project Managers/Supervisors, basic Plumbing Apprenticeship and task training certification of labor skills. A joint committee of the organizations has been appointed and is already working on the curriculum for each of the four components of the project and development of the training and educational materials.
