Sample Passports MOMENTUM2.0 Test Materials
Abstract
As part of the MOMENTUM project (see Momentum | Universiteit Utrecht | Homepage (momentummicroplastics.nl)), sample passports were created with characterisation data of the produced test materials. In this publication the deliverable documents (sample passports) are published and made accessible for the public.
