This document provides key principles for the analysis of microplastics in drinking water and water with low content of natural suspended solids using thermo-analytical methods. This document is applicable for the determination of types of polymers and mass of microplastics in the sample. This document is not applicable for the determination of particle size, particle shape and particle numbers. This document is applicable for the detection of microplastics in drinking water and waters with low content of natural total suspended solids (TSS)1 1 ISO 6107 (1-100 mg/l) or lower if they interfere with determination; in future a reference to ISO 5667-27 is desirable, which is still under development.. This standard describes the detection of different sort of polymers, which are the main ones (most used in industry and most abundant in the environment) being: polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and polystyrene (PS). These types of polymers can be analysed by all thermo-analytical methods. Depending on the used thermo-analytic methods, additional further polymer can be detected, such as polyvinylchloride (PVC), polycarbonate (PC), poly-methylmethacrylate (PMMA) polyamides (PA), polyurethanes (PU) and as well as signals from PS-co-polymers2 2 Signals from PS-co-polymers can be derivate from tire wear and can be detect with the methods as well, but elastomers are outside the scope of this document..
