Since november 2019 our material shop for the acquisition of sample materials from proficiency tests already carried out are available online. Suitable sample materials can be easily ordered after a personal registration. Due to the personal registration, new customer numbers are assigned for this purpose, also for existing customers - different customers from one company therefore have different customer numbers.
You can not register for our proficiency tests via this shop system.
Please note: our material shop is currently only available in german.
