AFGC professional technical code 152-02, revision D of November 2019, covers double walled vessels used in the production or storage of liquefied gases at low temperature, together with atmospheric cryogenic vaporisers of the high pressure and bath types.
Revision D followed a change in the regulations. Earlier revisions tracked successive French administrative decisions, which is a reminder that this is a living document tied to national rules rather than a one time publication.
What the document covers
- Applies to double walled vessels used to produce or store low temperature liquefied gases.
- Also covers atmospheric cryogenic vaporisers of the HP and bath types.
- Prepared with participation from Bureau Veritas, the French regional authorities and the major industrial gas companies.
- Revision history tracks successive French regulatory decisions up to November 2019.
- Freely available from AFGC.
What it means for equipment
This document sits directly under two of our equipment families: vacuum insulated cryogenic storage tanks and ambient air vaporisers. For a French installation it defines how that equipment is kept legal once it is in service.
The practical consequence is on documentation. Design records, material certificates and the inspection history are what make the in-service regime workable, so they should be part of the supply scope rather than an afterthought.
