Full title and description

STB DIN ISO 16622:2003-03 — Meteorology — Sonic anemometers/thermometers — Acceptance test methods for mean wind measurements. This is the German adoption (DIN) of ISO 16622:2002, providing standardized acceptance test procedures for sonic (ultrasonic) anemometers and thermometers used to measure mean wind components and related quantities.

Abstract

Defines test methods to evaluate the performance of sonic anemometers/thermometers that use inverse-time measurement of the speed of sound along differently oriented paths. Applicable to 2‑component and 3‑component designs with full 360° azimuthal acceptance; includes procedures for assessing mean wind measurement performance and relevant accuracy/precision checks.

General information

• Status: Published / confirmed international standard (DIN adoption published).
• Publication date: ISO original: 26 September 2002; DIN adoption (German edition): March 2003.
• Publisher: International Organization for Standardization (ISO); German adoption published by Deutsches Institut für Normung (DIN).
• ICS / categories: 07.060 — Geology. Meteorology. Hydrology (meteorological instrumentation).
• Edition / version: Edition 1 (ISO 16622:2002); adopted as DIN ISO 16622 in 2003.
• Number of pages: ISO original: 21 pages; DIN (German-language publication) typically issued with additional national front matter (commonly 24 pages in the DIN edition).

Scope

The standard establishes acceptance test procedures for sonic anemometers/thermometers employing sonic time-of-flight (inverse-time) measurements of sound velocity along pre-defined path geometries. It specifies performance tests and acceptance criteria relevant to mean wind speed and direction measurements for instruments that measure two or three components of the wind vector across the full azimuthal range. The procedures are aimed at manufacturers, test houses and users performing type-acceptance or factory-acceptance testing.

Key topics and requirements

• Definitions and instrument classes: 2‑component and 3‑component sonic anemometer/thermometer designs.
• Test methods for mean wind measurement performance (procedures to measure trueness, repeatability and basic performance under defined conditions).
• Measurement geometry and alignment checks (path orientations, azimuthal acceptance).
• Acceptance criteria and reporting requirements for factory/type acceptance tests.
• References to general accuracy/precision methods and related metrology standards used in test evaluation.

Typical use and users

Used by meteorological instrument manufacturers, calibration and test laboratories, research institutions, national meteorological services, wind-energy developers and site assessors. Typical applications include factory acceptance testing, type approval, performance verification during procurement, and laboratory comparison tests for sonic anemometer/thermometer products.

Related standards

Normative and informative references commonly cited with ISO 16622 include standards on measurement accuracy and repeatability (for example ISO 5725 series), other meteorological instrument test methods, and comparative practices such as relevant ASTM standards for wind measurement characterization. Users should consult the normative references list in the standard for the complete set of linked documents.

FAQ

Q: What is this standard?

A: ISO 16622 establishes acceptance test methods for sonic (ultrasonic) anemometers and thermometers used to measure mean wind components; DIN ISO 16622 is the German-language adoption of ISO 16622:2002 (published in Germany in March 2003).

Q: What does it cover?

A: It covers test procedures, instrument geometry and alignment checks, performance measurement methods (trueness, repeatability) and reporting formats needed to perform acceptance testing of 2‑ and 3‑component sonic anemometers/thermometers.

Q: Who typically uses it?

A: Manufacturers, calibration/test laboratories, national meteorological services, research groups and wind‑resource analysts who need standardized acceptance testing and traceable performance verification of sonic anemometer/thermometer instruments.

Q: Is it current or superseded?

A: As published, ISO 16622:2002 is the authoritative edition and the DIN adoption was issued in March 2003. Users should check with their national standards body or the ISO catalogue for any subsequent revisions or confirmations; the ISO catalogue entry lists the 2002 edition as published and subject to periodic review.

Q: Is it part of a series?

A: It is a stand‑alone international standard produced by ISO/TC 146/SC 5 (meteorological instruments). It is one of several standards addressing meteorological measurement methods and instrument performance but is not formally a numbered multi‑part series.

Q: What are the key keywords?

A: Sonic anemometer, ultrasonic anemometer, sonic thermometer, mean wind, acceptance test, meteorology, wind instrumentation, DIN ISO 16622.
