Revised ASSE Standard for Chemical Dispensing Systems Now Available

ASSE 1055-2016, Performance Requirements for Chemical Dispensing Systems, has been designated as an American National Standard by the American National Standards Institute (ANSI), and is now available for purchase.

The 2016 edition of ASSE 1055 provides performance standards and compliance testing procedures for chemical dispensing systems with integral backflow protection. In industrial and institutional cleaning operations, it is convenient and economical to dispense cleaning solutions derived from potable water and concentrated products. Dispensing devices providing this function often have features intended to prevent cross-connection contamination. ASSE 1055 identifies accepted methods of backflow protection, as well as test methods for evaluating backflow systems incorporated into a chemical dispensing system.

“ASSE International, as a leading voice in the backflow prevention industry, gathered experts in the dispensing equipment industry to address concerns about the backflow of chemicals and high-hazard materials into the potable water system,” said Jamison Kortas, ASSE 1055 working group chairperson, Senior Manager of Global Regulatory Affairs at Ecolab, and Executive Steering Committee member of the Dispensing Equipment Alliance (DEA). “While meeting the chemical dispensing system’s goal of diluting a concentrated solution so the right amount of mixed solution is dispensed with minimal waste and footprint, ASSE 1055’s performance requirements protect against having high-hazard substances enter the potable water system.”

ASSE 1055 performance requirements include compliance testing for stability, temperature, pressure, endurance, backpressure, and backsiphonage, and detailed requirements for markings and manufacturers’ instructions.
