The proper installation and compliance of the gas system must be confirmed by two tests. One is the one-off gas system installation test (GSP) and the recurring gas test (GWP).

What is a GSP? The definition is: gas system installation test. Engineers from recognized testing organizations test the gas system once after installation. The basis for this is the European regulation ECE-R115 and can be recognized by the approval number, e.g. R115-000001. Gas systems that have not been tested immediately after installation must undergo an individual assessment. We will be happy to inform you about this.
