This standard gives requirements and corresponding testassessment methods applicable to leak detection kits, based upon volumetric loss from within the tank and\/or pipework system. The kits usually comprise: – Measuring Device – Evaluation Device – Alarm Device Intended use: Leak Detection kits are intended to be used inwith single or double skin underground tanks or single or double skin underground and\/or aboveground, pipework designed for flammable liquids having a flash point not exceeding 100 \u00b0C.<\/p>\n
