Thephrase Air Moving Device (or Air Mover ) refers toequipment such as, fans, blowers and other forced airmovement technologies. This specification sets require-ments for design, manufacture, and test application of AirMoving Devices, and is intended for use by the term end user as used in this document refers to theOEM or design/materials entity responsible for specifyingthe function and reliability of an Air Moving Device in afinal product DescriptionAir Moving Devices addressed in thisdocument are used in the electronics industry for the cool-ing of heat-producing components, and range from smalldevices mounted directly to hot components such as micro-processor air moving devices, to larger devices used toforce air through a chassis containing many heat dissipat-ing Parametersare comprised ofMechanical, electrical .

5 Environmental , include bearing design andgrease, rotor balancing, self induced vibration, general air-flow configuration, form factor (size, shape and wiringcolor), device orientation, air movement characteristics,acoustics, and materials used in fabrication of the define the electrical interface,including type of power (AC, DC, or Pulse Width Modula-tion), voltage, frequency and current needs, speed controland, where used, tachometer signal and any other electricalinterfaces provided by the air moving entail both shipping andoperating temperatures, humidity, shock and vibration Assurancerequirements include defi-nitions and requirements for testing the reliability of AirMoving PurposeThe purpose of this document is to create aset of consistent specifications of Air Moving Devices forthe electronics industry.

6 These specifications will apply tosuppliers of air moving devices, including their design andtesting, and will provide guidelines for the end user toensure adequate specifications for use in their products. Allof the specifications and requirements defined in this docu-ment are intended to be part of suppliers Air MovingDevices Certifications outlined by the customers and willship with first article and any design changes to the airmoving Terms and DefinitionsThe definition of all termsused hereinshallbe as specified in IPC-T-50 and asdefined (As an Acronym):As Agreed Between User and Supplier.(As a Term):Indicates additional or alternate requirementsto be decided between the user and the supplier in the pro-curement documentation.
