True or False: GCSB 149.10 requires 7 baseline measurements at 75 Pa before and after testing.

The statement is false because GCSB 149.10 does not require 7 baseline measurements at 75 Pa before and after testing. Instead, the standard may specify a different number of baseline measurements or a specific procedure that does not include this particular requirement. Understanding the exact criteria outlined in GCSB 149.10 is essential for accurate compliance and testing methods. It’s important to consider that baseline measurements are crucial for establishing the airtightness of a building, and while multiple measurements may enhance accuracy, the specific requirement in this standard does not explicitly state seven measurements in both phases of testing.
