Full title and description

Ventilation for buildings - Performance testing of components/products for residential ventilation - Part 2: Exhaust and supply air terminal devices. This European Standard specifies laboratory methods for determining aerodynamic, acoustic and related performance characteristics of exhaust and supply air terminal devices intended for residential ventilation systems; it is intended to produce reproducible, comparable data for manufacturers, test laboratories and specifiers.

Abstract

EN 13141-2:2010 defines test installations, procedures and measurement uncertainty limits to determine volume flow versus static pressure characteristics, pressure drop, acoustic emission (sound power and insertion loss), air diffusion characteristics (for supply devices) and other relevant performance parameters for residential exhaust and supply terminals. The standard provides stepwise test methods (multiple pressure bands / setpoints), environmental recording requirements and reporting formats so that products can be compared on a consistent basis.

General information

• Status: European Standard published as EN 13141-2:2010; national adoptions exist (for example BS EN 13141-2:2010). The 2010 edition superseded the earlier 2004 edition.
• Publication date: 2010 (CEN approval recorded 22 April 2010; published mid‑2010 / July 2010).
• Publisher: CEN (European Committee for Standardization); national standards bodies adopt the EN (e.g., BSI for the UK as BS EN 13141-2:2010).
• ICS / categories: 91.140.30 (Ventilation and air-conditioning systems).
• Edition / version: EN 13141-2:2010 (edition replacing EN 13141-2:2004).
• Number of pages: Typically published as a short technical specification (around 20–25 pages; commonly listed as 23 pages in public catalogues).

Scope

This part of EN 13141 applies to exhaust and supply air terminal devices used in residential ventilation systems. It covers laboratory methods for measuring aerodynamic performance (volume flow versus pressure characteristics, pressure drop), acoustic performance (sound power in reverberation rooms, insertion loss, sound insulation where applicable), diffusion characteristics for supply terminals, and requirements for test rig arrangement, instrumentation and measurement uncertainty. The procedures are intended for devices with fixed openings, manually adjustable openings or pressure-difference controlled operation, and are aimed at producing consistent test data for product development, certification and specification.

Key topics and requirements

• Measurement of flow rate versus static pressure to produce characteristic curves across defined pressure bands (multiple setpoints covering the manufacturer’s declared operating range).
• Defined test installations (test duct, flow straightener, fan and flow metering) and mounting arrangements to avoid leakage and narrow‑band noise.
• Acoustic tests: sound power level determination (reverberation room methods), insertion loss measurement and, where relevant, sound insulation tests using established EN/ISO acoustics methods.
• Specification of environmental conditions and recording (air temperature, barometric pressure) and measurement uncertainty limits so combined test accuracy is typically within a few percent.
• Reporting requirements: presentation of flow/pressure curves, selected test points, acoustic results and declared uncertainty so data are comparable between products and laboratories.

Typical use and users

Manufacturers of air terminal devices, independent and accredited test laboratories, HVAC design engineers and specifiers, acoustic consultants and certification bodies use EN 13141-2 to characterise product performance, produce datasheets and support compliance or tender documentation. The standard is also used in R&D and quality control to verify that products meet declared performance.

Related standards

EN 13141-2 is part of the EN 13141 series "Ventilation for buildings — Performance testing of components/products for residential ventilation" (other parts cover air transfer devices, range hoods, fans, cowls/roof outlets, packaged systems, whole‑dwelling units including heat recovery, humidity‑controlled devices, etc.). Part 1 (air transfer devices) was revised independently (EN 13141-1:2019); users should check the status of other parts in the series for the latest editions and cross‑references for test and acoustic methods (EN 12238, EN ISO 3744/3741, EN ISO 9614, EN ISO 10140‑2, ISO 5801 and related documents).

FAQ

Q: What is this standard?

A: EN 13141-2:2010 is a European Standard that specifies laboratory test methods for determining the aerodynamic and acoustic performance of exhaust and supply air terminal devices used in residential ventilation systems.

Q: What does it cover?

A: It covers test installations and procedures for measuring volume flow versus static pressure (flow/pressure curves), pressure drop, acoustic emission (sound power and insertion loss), air diffusion (supply devices), environmental recording and measurement uncertainty; it sets out how to present results to ensure comparability.

Q: Who typically uses it?

A: Product manufacturers, accredited test laboratories, HVAC and building services engineers, acoustic consultants and certification bodies use the standard for product development, certification, selection and specification in residential ventilation projects.

Q: Is it current or superseded?

A: EN 13141-2:2010 replaced the 2004 edition (EN 13141-2:2004). As of the publication information available for the EN 13141 series, the 2010 edition is the recorded EN version for part 2; users should verify with their national standards body or the CEN catalogue for any amendments or later revisions that may have been published after 2010. (Note: other parts of the EN 13141 series have been revised at later dates — for example EN 13141-1 was revised in 2019 — so checking the current status of each part is recommended.)

Q: Is it part of a series?

A: Yes — EN 13141-2 is Part 2 of the EN 13141 series "Ventilation for buildings — Performance testing of components/products for residential ventilation." The series contains multiple parts covering different component types and packaged units; cross‑referenced standards for acoustics and fan testing apply.

Q: What are the key keywords?
