Testing jointing seams of sealing tapes e.g. for roofing - by filling space between parallel seams with pressure medium detectable by naked eye and/or sensor

摘要

A method of testing the joint seams of sealing tapes with two parallel seams at a small distance apart in the overlapping region of the sealing tapes involves filling the space between the seams with a pressure medium. A medium other than air is used. It can be detected with the naked eye and/or with the aid of a detector. The medium used can be helium. USE/ADVANTAGE - Sealing tapes for roofs and deposits. Costs are reduced where pressure drop is necessary for testing.
