Lenzing Wetback

Measuring rewet properties according to EDANA/INDA WSP 80.10 (former ERT 151) and WSP 70.8 (former ERT 154) – with reliable comparability of test conditions.


  • Best possible repeatability of the test procedure and therefore objectiveness
  • Comparability
  • Automated test routine without operator influence
  • Prepared for the use in combination with LISTER

In Detail

The rewet test is mostly used for diapers and sanitary goods. It measures the capacity of a nonwoven coverstock to hold back liquids even under the pressure of weight – just think of a wet diaper under the weight of a baby. This test is widely used but varies very much because of manual handling. The WETBACK offers reliable results by its automatic measurement procedure.







Lenzing Lister AC

Liquid strike through test according to EDANA/INDA WSP 70.3 (former ERT 150) and WSP 70.7 (former ERT 153) is automated measuring penetration properties.


  • Automated measurement – less mistakes
  • Standardized and used all over the world

In Detail

LISTER AC is an easy-to-use instrument providing reliable data on the time needed for a liquid to penetrate a non woven coverstock and is absorbed by a standardised filter paper.







Automatic Hydrostatic Head Tester


Measures the resistance of plastic foils, coated and uncoated fabrics and non-wovens to water penetration by means of the dynamic, static and program test method.
