The American Society of Mechanical Engineers (ASME), the American Society of SanitaryEngineering (ASSE) and CSA Standards have signed an agreement to harmonize five standardsconcerning automatic compensating valves, anti-siphon fill valves, trap seal primers, pressurizedflushing devices (flushometers), and water temperature limiting devices.

Standardshave signed an agreement to harmonize five standards

primers, pressurized flushing devices (flushometers) and water temperature
The harmonization agreement is designed
to help bring clarity to the plumbing community, especially to the
manufacturers of devices covered by the harmonized standards.
The agreement between the three
organizations states the purpose of the harmonized standards is to assist U.S.
and Canadian manufacturers by eliminating duplicate efforts of writing
standards for the same products in different countries, which will allow each
product to be designed, manufactured and tested to a common standard. This will
help provide assurance of consistent, high-quality products, help reduce costs
(for producers and consumers) and also help to provide a common basis for
The first harmonized standard, for
Performance Requirements for Automatic Compensating Valves for Individual
Showers and Tub/Shower Combinations, is expected to be completed and ready for
distribution later this year.
Each of the ASME/ASSE/CSA harmonized
standards will allow comparable testing of products for the U.S. and
Canadian markets. The harmonized standards have an ultimate goal of requiring
compliance to one standard and one test, providing a fair process for
assessment for manufacturers and buyers in different countries and helping
maintain or improve on the current level of product performance.
The harmonized standards will be
maintained on an ongoing basis to address new technologies, allow for regional or
regulatory differences and move toward performance-based requirements and
standards where it is practical and possible.
