Full title and description

Fans — Vocabulary and definitions of categories — Part 2: Categories. This international standard defines the classification (categories) used for fans for all purposes and provides standardized category names and descriptions to be used in specifications, documentation and industry communication. It is explicitly not applicable to electrical safety.

Abstract

Part 2 of ISO 13349 establishes the set of fan categories (for example by pressure capability, construction and transmission arrangement, inlet/outlet conditions, control method and characteristic dimensions) and clarifies how those categories are named and applied across the industry to harmonize terminology and classification. The document complements Part 1 (vocabulary).

• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 23.120 (Ventilators. Fans. Air‑conditioners); also referenced with general vocabulary ICS 01.040.23 in related catalogues.
• Edition / version: Edition 1 (ISO 13349‑2:2022).
• Number of pages: 26 pages (ISO published version).

Scope

Defines categories in the field of fans used for all purposes and provides standardized categorical names and descriptions for use in specifications and documentation. The standard does not address electrical safety requirements or electrical testing of fans. It is intended to be used alongside ISO 13349‑1 (vocabulary) and other dimensional and performance test standards.

Key topics and requirements

• Standardized fan category definitions (e.g., axial, centrifugal, mixed‑flow and subcategories by blade/shroud geometry and pressure class).
• Classification by performance capability such as low/medium/high pressure types and characteristic dimensions.
• Definitions for constructional and installation-related categories (transmission arrangement, inlet/outlet conditions, mounting/part position).
• Reference to vocabulary and symbols/units established in Part 1 to ensure consistent use of terms (e.g., qV, pF, P, N, ρ).
• Intended use as a normative classification reference for specifications, procurement, technical documentation and standards alignment (not a test method).

Typical use and users

Manufacturers, specification writers, consulting engineers, HVAC designers, procurement teams, test laboratories and standards committees use this standard to ensure consistent category names and classifications in product literature, tender documents, technical reports and cross‑border trade. It is particularly useful where clear category-based requirements are needed across suppliers and projects.

Related standards

ISO 13349‑1:2022 (Part 1 — Vocabulary) is the companion document that defines the terms used by Part 2. ISO 13349:2010 was withdrawn and superseded by the 2022 two‑part publication. Regional/adopted versions exist (for example EN/BS/National adoptions of EN ISO 13349‑2:2022).

FAQ

Q: What is this standard?

A: ISO 13349‑2:2022 is Part 2 of the ISO 13349 series and provides the standardized set of categories (classifications) for fans used across industries. It complements Part 1 (vocabulary).

Q: What does it cover?

A: It covers the names, definitions and scope of fan categories (by construction, performance class, installation and other classification criteria). It is a classification and terminology standard, not a test method or electrical safety standard.

Q: Who typically uses it?

A: Manufacturers, specifiers, HVAC and mechanical engineers, testing and certification bodies, procurement teams and standards committees use it to harmonize product classification and documentation.

Q: Is it current or superseded?

A: ISO 13349‑2:2022 is the current published Part 2 (published 22 September 2022). It and ISO 13349‑1:2022 supersede the earlier consolidated ISO 13349:2010, which has been withdrawn.

Q: Is it part of a series?

A: Yes — it is Part 2 of the ISO 13349 series; Part 1 (ISO 13349‑1:2022) defines the vocabulary and is intended to be used together with Part 2.

Q: What are the key keywords?

A: Fan categories, classification, terminology, axial fan, centrifugal fan, mixed‑flow fan, pressure class, installation, ISO 13349.
