Full title and description

ISO 13348:2007 — Industrial fans — Tolerances, methods of conversion and technical data presentation. This International Standard specifies performance tolerances and conventions for presenting technical data for industrial fans of all types, and provides guidance for unit conversion and data-layout to support clear communication between manufacturers, test laboratories and users.

Abstract

Specifies tolerances on performance values and the methods to convert and present technical data for industrial fans. It applies to fans for industrial use and covers the four installation categories defined in ISO 5801 (A: free inlet/free outlet; B: free inlet/ducted outlet; C: ducted inlet/free outlet; D: ducted inlet/ducted outlet). The standard excludes fans designed solely for low‑volume household air circulation (for example, ceiling and table fans, small extractor fans).

Scope

ISO 13348:2007 sets out permitted tolerances for published fan performance data (such as airflow and pressure), gives standardized methods for converting between units, and defines how technical data should be presented so that fan performance and selection data are comparable and unambiguous across suppliers and users. It is intended for industrial fans and excludes small household fans. The standard addresses data presentation across the four installation categories used for fan performance assessment (ISO 5801 categories A–D).

Key topics and requirements

• Defined performance tolerances for published fan data (airflow, pressure, efficiency and related parameters).
• Standardized methods for unit conversion to ensure consistent reporting of values.
• Guidance on the presentation format of technical data (tables, characteristic curves, reference conditions).
• Classification of installation categories (A, B, C, D) and their influence on performance data.
• Requirements for reporting test conditions and reference states to allow fair comparison between products.

Typical use and users

Used by fan manufacturers, HVAC and process engineers, test laboratories, product specification writers, procurement teams and standards committees to ensure consistent presentation and comparison of fan performance data and to reduce ambiguity in product datasheets and technical communication.

Related standards

Commonly used alongside ISO 5801 (performance testing and installation categories for industrial fans). ISO 13348:2007 has subsequently been withdrawn and updated by a later edition (ISO 13348:2025). Earlier drafts/versions include ISO 13348:2006 and Amendment documents; ISO/TC 117 is the technical committee responsible for fan standards.

FAQ

Q: What is this standard?

A: ISO 13348:2007 is an International Standard that defines tolerances, unit‑conversion methods and conventions for presenting technical performance data for industrial fans to ensure consistency and comparability.

Q: What does it cover?

A: It covers permitted tolerances on published fan performance values, how to convert units reliably, and how to present technical data (tables, curves and reference conditions). It applies to industrial fans and addresses the four installation categories defined in ISO 5801; it does not apply to small household fans.

Q: Who typically uses it?

A: Fan manufacturers, HVAC/process engineers, test laboratories, procurement/specification authors and standards developers use this standard to publish, interpret and compare fan performance data.

Q: Is it current or superseded?

A: ISO 13348:2007 has been withdrawn and superseded by a more recent edition (ISO 13348:2025). Users requiring the current normative requirements and the latest technical content should consult the 2025 edition.

Q: Is it part of a series?

A: It is part of the body of standards addressing fans and ventilators maintained under ISO/TC 117 and is used together with ISO 5801 (fan performance test methods and installation categories) and related ISO documents covering fan testing and selection.

Q: What are the key keywords?

A: industrial fans, tolerances, performance data, unit conversion, technical data presentation, installation categories (A–D).
