What is the newest air testing standard expected to be published by 2024?

The selection of ASTM E3158 - 18 as the expected newest air testing standard by 2024 is rooted in its relevance and potential updates to emerging practices in the field of airtightness testing. ASTM E3158 outlines guidelines for air leakage testing specifically for buildings, which is a critical aspect in assessing energy efficiency and overall building performance.

With the evolution of building codes and standards emphasizing enhanced energy performance and sustainability, newer standards like ASTM E3158 are designed to reflect contemporary methodologies and technologies for testing airtightness. This makes it a relevant choice for those focused on aligning with best practices in energy management and building science.

While other options represent existing standards, they may not have the same level of recent updates or anticipated relevance moving forward in the context of airtightness testing. The implication of selecting ASTM E3158 suggests an awareness of ongoing developments and a proactive approach to incorporating newer standards into building practices, ensuring compliance with the latest requirements in the industry.
