Abstract
Overview
ISO 4907-1:2023 - Plastics - Ion exchange resin - Part 1 specifies standardized laboratory methods for determining the . The standard defines procedures to quantify three functional-group capacities: , and of acrylic resins in their defined “standard form”. Methods rely on controlled chemical reactions and titrations and include requirements for reagents, apparatus, sampling, sample preparation, calculations and test reporting.
