What is the typical range of test pressure specified by ISO 9972:2015?

• A. 1-5 Pa
• B. 10-50 Pa
• C. 50-100 Pa
• D. 100-150 Pa

Answer: (B)

The typical range of test pressure specified by ISO 9972:2015 is 10-50 Pa. This standard outlines the testing methods for measuring the airtightness of buildings, emphasizing the importance of maintaining a consistent test pressure to obtain accurate and reliable results. The pressure range of 10-50 Pa is considered optimal for assessing the tightness of a building envelope under realistic operating conditions, allowing for effective identification of air leakage paths. Utilizing pressures within this range helps ensure that the tests reflect how buildings will perform in real-world scenarios, making it critical for compliance with energy efficiency and building performance standards.
