The design temperature is -70°C. It seems that this material isn’t covered in the amendment order number one. The local inspection authority requires us to submit a technical review – or is it sufficient to just conduct re-inspection of the material?

The manufacturer of this material provides it. .

Comply with Article 2.1.2 of the major specifications; the technical review is also carried out by the material manufacturing unit.
