Annex A (informative) A-deviations

This European Standard specifies the properties and the test methods of sealants used to reseal threaded joints of metallic gas pipework in buildings operated at a maximum allowed operating pressure of 100 mbar (such sealants hereafter are referred to as "sealants"). Note Gas pipework in buildings is in accord ance with EN 1775 the pipework between the point of delivery and the inlet connection to the gas appliance.
