Non or slightly conductive materials and coatings such as 3 layer PE / PP can reliably be tested for pores or other damage. The same goes for foils and rubber coatings to which this non-destructive testing with a minimum of material stress applies as well by ISOTEST act 35.

All ISOTEST® holiday detectors have undergone extensive tests in the field of safety and EMC. They all carry the CE label and fulfil the requirements of all relevant standards and specifications (DIN EN / ISO / DVGW etc.)
