Full title and description

ISO 10302-2:2011 — Acoustics — Measurement of airborne noise emitted and structure-borne vibration induced by small air-moving devices — Part 2: Structure-borne vibration measurements. This part of ISO 10302 specifies laboratory methods for measuring the structure-borne vibration that small air-moving devices (AMDs) induce in typical information-technology and telecommunications equipment structures; it complements the airborne-noise methods given in Part 1.

Abstract

ISO 10302-2:2011 covers vibration levels from small air‑moving devices with defined maximum mounting footprints for the full‑size and half‑size test plenums. It specifies procedures to determine the vibration levels an individual AMD would induce in an average structure used in information technology and telecommunications equipment and provides measurement and statistical procedures to characterise individual units and production series.

Scope

Specifies laboratory measurement methods for structure‑borne vibration induced by small air‑moving devices (AMDs) mounted on the inlet or discharge plane of a test plenum as defined in ISO 10302‑1. Applicable footprint limits for tested AMDs are given for full‑size and half‑size plenums; the standard is intended to provide reproducible, comparable data that can be used for engineering design, equipment specification and statistical characterisation of production series.

Key topics and requirements

• Definition of applicable AMD types and maximum mounting footprints for full‑size and half‑size test plenums.
• Test‑plenum mounting arrangements and mounting plane definitions consistent with ISO 10302‑1.
• Measurement instrumentation and sensor placement for structure‑borne vibration (accelerometers, mounting, calibration).
• Procedures for measuring induced vibration levels in a representative receiving structure and for reporting results.
• Data analysis and statistical treatment to characterise individual units and production batches.

Typical use and users

Used by acoustics and vibration test laboratories, AMD (fan and blower) manufacturers, equipment designers for IT and telecommunications enclosures, and procurement/specification engineers who require comparable, reproducible vibration data for product selection, design validation and supplier acceptance testing.

Related standards

ISO 10302 is a multi‑part standard. Part 1 (ISO 10302‑1:2011) covers airborne noise measurements for small AMDs and specifies the test plenum and airborne measurement methods that Part 2 references; Part 1 has since been revised and a newer edition is available. Earlier work includes ISO 10302:1996 (withdrawn) which was superseded by the 2011 split into Parts 1 and 2.

FAQ

Q: What is this standard?

A: ISO 10302‑2:2011 is the Part 2 component of the ISO 10302 series specifying laboratory methods for measuring structure‑borne vibration induced by small air‑moving devices.

Q: What does it cover?

A: It covers measurement procedures, mounting and test‑plenum definitions, instrumentation and data analysis needed to determine the vibration an AMD would induce in a typical IT/telecom structure, and gives guidance for statistical characterisation of units and production series.

Q: Who typically uses it?

A: Acoustics and vibration test laboratories, AMD manufacturers, enclosure and equipment designers, and procurement/specification engineers.

Q: Is it current or superseded?

A: As published in June 2011, ISO 10302‑2:2011 is listed as a published International Standard and was confirmed through review; users should verify the ISO catalogue for any subsequent revisions or confirmations before relying on it for regulatory or contractual requirements.

Q: Is it part of a series?

A: Yes — ISO 10302 is a series. Part 1 addresses airborne‑noise measurement (ISO 10302‑1) and Part 2 addresses structure‑borne vibration; the series replaced the earlier ISO 10302:1996.
