Scope

The scope of this standard includes all electric motor driven fan systems that utilize a specific
combination of components as defined below:
1) Fan airflow performance tested in accordance with ISO/Standard 5801, Industrial fans --
Performance Testing Using Standardized Airways.
2) Polyphase induction motors within the scope of the US Energy Independence and Security Act of
2007, IEC 60034-30, Rotating electrical machines – Part 30-1: Efficiency classes of line operated AC
motors, or GB 18613, Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades
for Small and Medium Three-Phase Asynchronous Motors. Other types of motors are explicitly
excluded.
3) Pulse-width modulated variable frequency drives (VFD) for use with single motors. Single VFDs
that service multiple, parallel fan motors are excluded.
4) Mechanical power transmissions that utilize V-belts, flat belts, cog belts, or couplings.
