Heubach Test
The Heubach tests required in ESTA/SeedGuard may only be carried out by qualified/certified laboratories according to ESA's standardized method "Assessment of free floating dust and abrasion particles of treated seeds as a parameter of the quality of treated seeds". Laboratories that carry out Heubach tests are obliged to provide proof of compliance with the above-mentioned reference method. On the one hand, successful participation in a laboratory competence test (ring test) or successful CoP certification by the certification body SGS Germany GmbH serves this purpose.
