Full title and description

ISO 13347-1:2004/Amd 1:2010 — Industrial fans — Determination of fan sound power levels under standardized laboratory conditions — Part 1: General overview — Amendment 1. This one-page amendment updates and clarifies aspects of the Part 1 general overview for acoustic measurement of industrial fans under laboratory conditions.

Abstract

This amendment (Amd 1:2010) to ISO 13347-1:2004 provides limited technical and/or editorial changes to the Part 1 general overview of the ISO 13347 series, which addresses methods for determining fan sound power levels under standardized laboratory conditions. The underlying Part 1 and the ISO 13347 series set out measurement principles used when assessing the acoustic performance of industrial fans and fan-plus-ancillary-device combinations.

Scope

This document is a narrow amendment to ISO 13347-1:2004 (Part 1 — General overview) and does not constitute a standalone measurement method. Its scope is limited to clarifications and corrections that modify or explain aspects of the Part 1 overview used by laboratories and test houses when following the ISO 13347 series procedures for determining fan sound power levels in standardized laboratory conditions. The amendment is intended to be read in conjunction with ISO 13347-1:2004 (and the other parts of the series).

Key topics and requirements

• Clarifications to the Part 1 general overview and terminology used across the ISO 13347 series.
• Editorial or technical updates intended to improve consistency with other parts of ISO 13347 (measurement principles and reporting basics).
• Instructions to be applied alongside the full measurement procedures given in the numbered parts of ISO 13347.
• No standalone measurement procedures are introduced by the amendment; it modifies or explains existing Part 1 content.

Typical use and users

Used by acoustics laboratories, fan manufacturers, test houses, certification bodies, and product engineers who perform or interpret laboratory sound power measurements on industrial fans and fan-plus-ancillary-device combinations. Users consult this amendment together with ISO 13347-1:2004 and the other parts of ISO 13347 to ensure correct application of terminology and overview-level requirements.

Related standards

This amendment is part of the ISO 13347 series (Part 1 — general overview; Parts 2, 3, etc., cover specific measurement methods such as microphone arrays and enveloping surface methods). ISO 13347-1:2004 and its amendment Amd 1:2010 have been withdrawn and the series was revised; the Part 1 content has been superseded by ISO 13347-1:2025. Users should refer to the 2025 revision for the current consolidated requirements.

FAQ

Q: What is this standard?

A: It is Amendment 1 (2010) to ISO 13347-1:2004, which provides limited updates to the Part 1 general overview of the ISO 13347 series on determining fan sound power levels under standardized laboratory conditions.

Q: What does it cover?

A: The amendment covers clarifications and corrections to the general overview (Part 1) used when applying the ISO 13347 measurement series; it does not introduce standalone measurement procedures and must be used together with the main Part 1 document and other numbered parts of ISO 13347.

Q: Who typically uses it?

A: Acoustical test laboratories, fan manufacturers, product engineers, certification bodies and anyone performing or interpreting laboratory fan sound power measurements under the ISO 13347 framework.

Q: Is it current or superseded?

A: ISO 13347-1:2004/Amd 1:2010 is withdrawn. The Part 1 content has been superseded by a later consolidated revision (ISO 13347-1:2025); users should consult the 2025 edition for the current requirements.

Q: Is it part of a series?

A: Yes. It is an amendment to Part 1 of the ISO 13347 series (industrial fans — determination of fan sound power levels under standardized laboratory conditions), which includes multiple parts addressing different measurement techniques and reporting.

Q: What are the key keywords?

A: Industrial fans, fan sound power, acoustics, laboratory measurement, ISO 13347, amendment, ISO/TC 117.
