What is ISO 23658 about?    ISO 23658 is an international standard on b uildings and civil engineering works which covers testing of adhesion properties using a bead peel test.   ISO 23658 specifies a method for evaluating the adhesion of sealants with a minimum elongation at a break of 25 % (according to ISO 8339, Method A or B) on various substrates. This test method can be used for one-component and multi-component sealants. This method is typically used for elastic sealants but can be also used for plastic sealants. For plastic sealants, the test can be more difficult and needs to be carried out by experienced technicians.   An adhesion test according to ISO 23658 can also be conducted for process monitoring and quality assurance accompanying production.
