If you are a manufacturer of diffusers, grilles, registers, or unit ventilators, Standard 70-2006 (or the updated 2023 version) defines the exact protocol you must follow to legally claim compliance or generate catalog performance data.
: Defines updated test facility and installation procedures to more accurately reflect how devices perform in their intended applications. Calculation Clarity : Updates test facility and installation definitions to
Remember that Standard 70 data is under ideal conditions. Do not expect to perfectly replicate Standard 70 results in a field test due to ductwork losses and installation variables. Use the standard as a benchmark for product comparison, not as a field acceptance test.
ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) Standard 70-2006 is a widely recognized standard that provides guidelines for the thermal performance of buildings. The standard, titled "Method of Testing the Performance of Air-to-Air Heat Recovery Ventilators," outlines the testing and rating procedures for air-to-air heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs). : Defines updated test facility and installation procedures
In spaces like schools, theaters, and hospitals, maintaining strict NC levels is mandatory. Standard 70 data prevents unexpected, noisy system behavior after installation.
Defines standard laboratory methods to measure air outlet/inlet performance.
Determining airflow capacity and pressure drop.
