Fiberglass Storage Tanks

[Inchtain]

Dear Gents,

Could you possibly inform me whether in-service horizontal foam concentrate fiberglass storage tanks (2000liters) are subjected to periodic inspections? and whether they are considered pressure vessels and required to be certified by a third party?

I wonder what checks can be done to them? and which code/standard governs their inspection?

Thanks and best regards
