HighNCT-R-INS-001
The calibrated range ends at 100 barg; NCT-INS-SP-0002 Rev 1 §3.1 requires at least 165 barg (1.1 x design pressure).
MediumNCT-R-INS-002
Ingress protection is IP65, below the minimum IP66 required by NCT-INS-SP-0002 Rev 1 §3.2.

HighNCT-R-INS-003
'Ex d IIA T3 Gb, Zone 1' is not an allowed value; NCT-INS-SP-0002 Rev 1 §3.3 allows only: gas group IIB or IIC with temperature class T4, T5 or T6.

HighNCT-R-AFP-003
The document specifies unfiltered seawater as the test medium, which directly contradicts the requirement that the test medium shall be filtered fresh water (50 µm or finer) with a corrosion inhibitor and that seawater is not allowed.
HighNCT-R-PRC-007
The procedure specifies seawater as test medium for a dense-phase CO2 line. Seawater contains dissolved salts and impurities; after drying, residual salt deposits and moisture can remain in the pipe, contradicting the requirement that free water shall never be present in operation and water content shall be max 50 ppmv.
