The IEC webstore often provides a free "Preview" document containing the table of contents, scope, and introductory text, which can help confirm if the document fits your needs before purchase. Summary of Recent Revisions
To ensure engineering accuracy and regulatory compliance, organizations should acquire the standard through authorized channels. Legitimate options include:
Organizations such as ANSI (USA), BSI (UK), or DIN (Germany) sell IEC standards often adapted as national standards (e.g., BS EN 60034-9).
An electric motor generates noise through three primary mechanisms, all of which are governed by the limits in IEC 60034-9:
By adhering to this standard, manufacturers ensure that their products do not exceed safe noise thresholds. This compliance helps factory operators design safer workspaces, minimize acoustic pollution, and avoid regulatory penalties related to environmental noise.

It differentiates noise limits based on whether a machine operates on a regular alternating current (AC) grid or via variable-frequency drives (VFDs). Scope and Applications
IEC 60034-9 is the international standard that specifies noise limits
Operating conditions during testing (e.g., no-load or rated load). Key Technical Specifications
Organizations like BSI (UK), ANSI (USA), or DIN (Germany) sell localized versions (e.g., BS EN IEC 60034-9) which match the core IEC text. The IEC webstore often provides a free "Preview"
The document's main objectives are to:
To ensure you have the correct, legal version for industrial compliance, consider these sources:
The official source for the most recent version (currently IEC 60034-9:2021 ).
It dictates the ceiling for airborne noise emitted by machines under specified test conditions. An electric motor generates noise through three primary
However, it's equally important to note what the standard . It does not provide noise limits for:
Investing in legitimate standards guarantees that your testing, manufacturing, and procurement processes are built on accurate, legally sound foundation.
The international standard sets the official limits for noise made by rotating electrical machines. If you are looking for a free PDF download of this document, you need to know how to find official copies and understand what the standard covers. What is IEC 60034-9?
The standard provides a uniform method for measuring and evaluating airborne noise emitted by standard-design machines, including: : Both AC and DC rotating electrical machines.
The standard categorizes machines based on their power output (kW), speed (RPM), and cooling method. Generally, as the size and speed of a motor increase, the allowable noise level also increases.
If your company is audited for ISO 9001 or safety standards, using an unauthorized or outdated document can lead to non-compliance. How to Access IEC 60034-9 Legally
