Bending and compression tests are done on extended poles to make sure they remain effective and can withstand stresses when the user has to lean on them heavily. Tests are also carried out to assess how the tightening systems cope with pulling, tightening and repeated stress, and pull tests on the tips and handles simulate poles getting stuck when in use.
Store poles in a dry place.
