Air tightness test
Test à l'air
The air tightness test lets you control the tightness of a pipe
according to protocol L of norm NF EN 1610.
There are 4 protocols: LA, LB, LC and LD. They have been developed for France and Europe in order to standardize the results of air tests.
The air tightness test is the most common control used in rehabilitation
to verify the tightness of a pipe.
