EEMUA 159 Inspection Interval Calculator

Tank inspection frequencies by product service group and climate, with adjustments for heating/insulation and internal coating (EEMUA Publication 159, Appendix B, Table B-1)

◉ EEMUA PUBLICATION 159 APPENDIX B, TABLE B-1 STYLE CHECK · NOT A REGULATORY SUBMISSION TOOL

⚠ Indicative tool only. These intervals are guidance, applicable only when tanks are properly repaired after each interval — a fit-for-purpose analysis should verify primary containment remains safeguarded through the next interval. Process systems, products not covered in Table B-1, foundation conditions, and local climate can all vary from site to site; local authorities or national legislation may require different intervals. After each detailed inspection, the Tank Integrity Assessor should set the next inspection date so that rejection limits stated elsewhere in EEMUA 159 aren't exceeded.
