Related Standard 610
Standard 610 Scope
This standard applies to electrically operated Central System Humidifiers that depend on the air stream of a central air system for moisture evaporation and distribution. Central System Humidifiers are intended for installation in central air systems. This standard does not apply to self-contained humidifiers, portable humidifiers, and humidifiers for commercial and industrial applications.

Standard 611 Scope
This standard applies to electrically operated Central System Humidifiers that depend on the air stream of a central air system for moisture evaporation and distribution. Central System Humidifiers are intended for installation in central air systems. This standard does not apply to self-contained humidifiers, portable humidifiers, and humidifiers for commercial and industrial applications.

Related Standard 620
Standard 620 Scope
This standard establishes a single set of requirements for the testing and rating of humidification capacity, power input, and energy input of supplementary heat (where used) for self-contained humidifiers for residential applications. Self-contained humidifiers are defined as humidifiers intended to be installed with a water make-up line and/or drain and electrical services — it may or may not be installed within the humidified space.

Related Standard 621
Standard 621 Scope
This standard establishes a single set of requirements for the testing and rating of humidification capacity, power input, and energy input of supplementary heat (where used) for self-contained humidifiers for residential applications. Self-contained humidifiers are defined as humidifiers intended to be installed with a water make-up line and/or drain and electrical services — it may or may not be installed within the humidified space.

Related Standard 640
Standard 640 Scope
This standard establishes a single set of requirements for the testing and rating of humidification capacity, power input, and energy input of supplementary heat (where used) for humidifiers used in commercial and industrial applications. Devices of the following types are included: atomizing, electric resistance steam generators, electrode steam generators, heat exchangers, infrared, steam injection, and wetted media.

 


 

 


Section Scope

 

Devices designed to add moisture to the air, including:

1. Central humidifiers, designed to add moisture to air circulated through ducts.

2. Central system humidifiers, designed to add moisture directly into a room or duct system but dependent upon associated outside generating source such as:

a. Steam grid duct.
b. Steam room humidifiers.
c. Pneumatic atomizing.

3. Fixed humidifiers, designed to add moisture directly to the space where the humidifier is located, excluding portable.

4. Self contained humidifiers, designed to add moisture directly into a room or duct system independent of associated outside generating source such as:

a. Electrode steam generators.
b. Electric evaporative.
c. Centrifugal atomizing.
