What are the three testing procedures defined per ASTM E3158 - 18?

• A. Multi-point, repeated two-point, and repeated single-point
• B. Single-point, continuous-point, and variable-point
• C. Multi-point, static-point, and dynamic-point
• D. Repeated zero-point, three-point, and control-point

Answer: (A)

The correct choice identifies the three testing procedures defined in ASTM E3158 - 18 as multi-point, repeated two-point, and repeated single-point. These procedures are crucial for assessing airflow rates and ensuring the building maintains its intended performance regarding airtightness. Multi-point testing involves taking measurements at multiple points across the building to provide a comprehensive analysis of airflow. This thorough approach helps to identify variations in air leakage that may not be evident through single-point measurements. Repeated two-point testing involves taking measurements at two different points and repeating this process to confirm the reliability and consistency of the results. This method helps to ensure that the data collected is not anomalous and reflects true performance. Repeated single-point testing, as the name suggests, involves measuring air leakage at a single location repeatedly to gather data over time. This can help to track changes in airtightness due to various conditions such as temperature and humidity, which could affect building performance. Understanding these testing procedures is essential for professionals involved in ensuring building performance and compliance with building standards.
