The legal requirements for the inspection and maintenance of aboveground tanks are laid down in directives. These directives may vary from country to country. In the Netherlands, each tank, and its maintenance, is required to be Kiwa-approved. In addition, the tanks must comply with VLG/ADR and UN standards.
