IAPMO Standards is currently seeking Canadian representation in Plumbing Standards Committee in the “Enforcing Authority,” “Consumer,” and “User” interest categories.

Enforcing Authority and Consumers are defined as follows:

Enforcing Authority: a representative or an agency or an organization that promulgates and/or enforces standards (e.g., regulatory agency, inspectors and enforcers).

Consumer: a person who is, or represents, the ultimate purchaser of a product, system, or service (e.g., end user of a product and distributor).

User: a representative of an entity that is subject to the provisions of the standard or that voluntarily uses the standard (e.g., educator, skill-trade trainer, skill trades person and academia).

If you wish to serve on the technical committee, please submit your application online at IAPMO Technical Committee Application or contact standards@IAPMOstandards.org.

When a new and novel product comes to the market, the industry must have confidence that the product will function as intended, but most importantly, it is safe for public use.

The IAPMO Industry Standards undergo a rigorous development and revision procedure with the input from interested stakeholders including manufacturers, city officials, building and plumbing inspectors, and product distributors through our open consensus standards development process. This includes a 20-day public review period, where the draft standard is published on our public review webpage.

Through our industry standards, IAPMO provides manufacturers and product developers a vehicle for introducing new products to the marketplace in timely manner.

Under Public Review:

None
