True or False: ISO 9972:2015 only specifies a multi-point method for testing.

ISO 9972:2015 establishes a standard for measuring the air permeability of buildings and outlines various testing methods, including both single-point and multi-point methods. Therefore, stating that ISO 9972:2015 specifies only a multi-point method is inaccurate. A better understanding of this standard recognizes that it supports multiple approaches to ensure proper assessment of a building’s airtightness, making the assertion that it involves solely the multi-point method incorrect.
