Windows and doors - Air permeability - Test method

This document specifies the test method to determine the air permeability of completely assembled windows and pedestrian door sets of any material, when exposed to positive or negative test pressures. This test method is designed to take account of conditions in use, when the window or door set is installed in accordance with the manufacturer’s specification and the requirements of relevant International Standards and codes of practice. This document does not apply to joints between the window or door frame and the building construction.

Overview

ISO 6613:2023 - "Windows and doors - Air permeability - Test method" is the international test method for measuring air permeability (air leakage) of completely assembled windows and pedestrian door sets of any material. It specifies laboratory procedures, equipment and reporting requirements for both positive and negative test pressures, and is intended to reflect in-use conditions when specimens are installed per manufacturer instructions and relevant codes. The standard does not cover the joint between the frame and the building construction.

Key topics and technical requirements

• Scope and terms: Defines key terms such as air permeability, test pressure, opening joint, length of opening joint and overall area (see ISO 22496 for vocabulary).
• Test apparatus: Requires a pressure-rated test chamber with one open side, controlled pressure application (including rapid pressure changes), and an airflow instrument with specified accuracy (±5% for flows >1 m3/h; ±0.05 m3/h for flows ≤1 m3/h).
• Specimen preparation: Specimens must be fixed as intended for use, fully operable, clean and dry. Ventilation devices are normally sealed unless their flow is being measured.
• Environmental conditioning: Test specimen conditioned at 10–30 °C and 25–75% RH for at least 4 hours before testing; temperature and humidity tolerances are specified.
• Pressure sequences: Apply pressure in steps of 50 Pa to 300 Pa, then 150 Pa increments above 300 Pa. Pulse tests (three pulses) are required prior to step measurements (external: pulses 10% above max or 500 Pa; internal doors: 10% above max or 150 Pa).
• Chamber correction: Procedures to measure and account for test chamber leakage. If chamber leakage is <5% of the classification limit it may be treated as zero; in no case shall chamber leakage exceed 30% of the combined specimen+chamber leakage.
• Results and normalization: Airflow results are adjusted to standard conditions (293 K, 101.3 kPa) and expressed per unit joint length (m3/(h·m)) or per unit area (m3/(h·m2)) as applicable. Reporting must include measurement accuracy and test conditions.

Applications and users

• Manufacturers of windows and pedestrian doors - to verify product performance and support product data sheets.
• Independent test laboratories - to perform standardized air leakage testing for certification and compliance.
• Certification bodies and regulatory authorities - to assess conformity with building codes and performance classes.
• Façade engineers, architects and specifiers - to select products that meet thermal comfort, energy efficiency and ventilation design requirements.
• Building owners and contractors - to interpret test reports and ensure installed units meet expected airtightness.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
