2.four This conventional doesn't handle these types of non-thermal environmental things as air high-quality, acoustics and illumination; or other Actual physical, chemical or biological space contaminants that may have an affect on consolation or overall health.
2. SCOPE: This doc provides assistance to the treatments to follow when measuring gas-phase concentrations of contaminants in business buildings. The subject measurements are These utilised to ascertain existing, baseline or transformed conditions to be a perform on the building programs or interior environments.
one. Intent: This typical establishes a uniform means of laboratory tests for score packaged and component immediate evaporative air coolers.
This Common would not implement to walk-in coolers, or refrigerators and freezers where by the refrigerated air is in conversation with stroll-in coolers.
b. modifications which includes alternative of parts or parts if they aren't equivalent in functionality and ability; and
Air conditioning models use mostly for convenience cooling for which screening approaches are provided in other expectations
2.four Although the normal may very well be applied to both new and present structures, the provisions of this typical usually are not intended to be utilized retroactively if the conventional is used as a compulsory regulation or code.
