    So it looks like job site inspections are now required to be performed by a 6020 or 6030 per NFPA 99, 2018.  The scope of work only includes witnessing the installer's soap test (initial leak test) and labeling. (which I'm calling the scope of work) allows the AHJ or designee to witness the initial leak test instead of an ASSE 6020 or 6030.  The labeling must be inspected only by a 6020 or 6030.  

    Is it also required to follow the scope of work from the ASSE 6020 in addition to this new NFPA code (i.e. documentation review, job site inspections, etc.)?  In the scope of work from ASSE 6000 the 6020 inspector must review the verifier's report and credentials.  That would imply that the inspector and verifier must be different entities?

    I'm not interested in being on a job site daily to watch the installer do his initial pressure test every day during a 6 month job.

    Reference:  NFPA 99, 2018

    and what of this question ?

    ? Is it a conflict for the persons or company, that install the low voltage wiring - to certify and test they our work ?


    From the information listed below, in my opinion, I believe it could.


    By definition the switch wiring, is part of the distribution system.

    Distribution system shall be Inspected (see and Verification


    Chapter 3 Definitions

    3.3.143  Piped Distribution System. A pipeline network assembly of equipment that starts at and includes the source valve,warning systems (master, area, local alarms), bulk gas system signal actuating switch wiring, interconnecting piping, and all other components up to and including the station outlets/inlets.
