Not everyone seemed comfortable turning over NH3 Refrigeration Codes and Standards to the IIAR. In November, Wisconsin updated its State Code on Mechanical Refrigeration. One of the requirements that caught my eye is the INSTALLATION INSPECTION documentation the state will require before issuing the operating permit:
(2) INSTALLATION INSPECTION.
… the following documents shall be made available for review during inspections under this paragraph:
- Welding procedure specification.
- Procedure qualification record.
- Welder performance qualification.
- Welder continuity record.
- Design calculations.
- Design plans for the piping system.
- Material test reports.
- Certificates of compliance.
Here are the applicable sections of the code:
