Clearly it's written that both the tests are to be documented and witnessed

by the AHJ or this Designee or a 6020 or 6030:

Yes the Installer Initial Pressure Test and the Final 24 Hour Standing Pressure Test. On the pressures gases and vacuum with NF Nitrogen for the Initial Test then for the 24 hour test the gases with NF Nitrogen and vacuum with a vacuum pump.

What is not clear is, did anyone understand the impact.

As I wrote in a earlier post.

What percent of the Verifiers receive the required written form indicating the 24 hour standing pressures was performed and in written, at the start of all the test required in # 5.1.1.12.3
