In-service Inspection Scheme.

Stay compliant with UK legal requirements, while improving the reliability and availability of your pressure system.


LRQA developed its In-Service Inspection Scheme with the Pressure Systems and Transportable Gas Containers Regulations SI1989 No.2169 in mind.

The comprehensive scope of the Scheme covers all foreseeable potential hazards to ensure compliance with all UK statutory requirements covering pressure systems. This scope has been regularly reviewed and updated and takes account of the Pressure Systems Safety Regulations SI2000 No. 128 (PSSR).
Finally, this is a UK scheme only used for the UK market only.
