Standards

Norms and directives

With our scientific instruments and application laboratory, we provide the world's largest selection of different measuring methods for characterizing surfaces and interfaces. In doing so, we place great importance on the replicability and standardization of our measuring results. We therefore work in accordance with the following EU, ISO and DIN norms and ASTM standards:

  • ASTM D 1173 (Reapproved 2015) / Standard Test Method for Foaming Properties of Surface-Active Agents (Ross-Miles)
  • ASTM 5725 / Standard Test Method for Surface Wettability and Absorbency of Sheeted Materials Using an Automated Contact Angle Tester
  • ASTM 724 / Standard Method for Surface Wettability of Paper (Angle-of-Contact Method)
  • ASTM C 813 / Standard Test Method for Hydrophobic Contamination on Glass by Contact Angle Measurement
  • ASTM D 971 / Standard test method for interfacial tension of oil against water by the ring method
  • ASTM D 1331 / Standard test method for surface and interfacial tension of solutions of surface active agents
  • ASTM D 1417 / Standard method of testing rubber latices-synthetic
  • ASTM D 1590 / Standard test method for surface tension of water
