Nanotechnologies - Evaluation of the mean size of nano-objects in liquid dispersions by static multiple light scattering (SMLS) (ISO/TS 21357:2022)
.
This document provides guidance and requirements for the determination of the mean (spherical) equivalent diameter of nano-objects (i.e. particles, droplets or bubbles) dispersed in liquids using the static multiple light scattering (SMLS) technique. The technique is applicable to a wide range of materials and does not require dilution of concentrated samples.
Nanotechnologien - Ermittlung der mittleren Größe von Nanoobjekten in flüssigen Dispersionen mit Hilfe von statischer Mehrfachlichtstreuung (SMLS) (ISO/TS 21357:2022)
Dieses Dokument enthält einen Leitfaden und Anforderungen für die Bestimmung des mittleren Äquivalent(kugel)durchmessers von Nanoobjekten (d. h. Partikeln, Tröpfchen oder Blasen), die in Flüssigkeiten dispergiert sind, mittels statischer Mehrfachlichtstreuung (SMLS). Das Verfahren ist für eine Vielzahl von Werkstoffen anwendbar und erfordert keine Verdünnung konzentrierter Proben.

Nanotehnologije - Vrednotenje srednje velikosti nanoobjektov v tekočih disperzijah s statičnim večkratnim sipanjem svetlobe (SMLS) (ISO/TS 21357:2022)
Ta dokument vsebuje smernice in zahteve za določanje povprečnega (sferičnega) enakovrednega premera nanopredmetov (tj. delcev, kapljic ali mehurčkov), razpršenih v tekočino s tehniko statičnega mnogoternega razprševanja svetlobe (SMLS). Tehnika se uporablja za širok nabor materialov in ne zahteva redčenja koncentriranih vzorcev.

This Technical Specification (CEN/TS) was approved by CEN on 17 March 2023 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
