ISO 14848:1998 PDF

Overview

ISO 14848:1998 is an international standard published by ISO that specifies a standardized method for determining the reactivity of unsaturated-polyester resins at 130 °C. These resins, widely used in thermosetting plastics, bulk moulding compounds (BMC), and sheet moulding compounds (SMC), require precise control of their polymerization behavior for effective processing and quality assurance.

This standard outlines the procedure to measure the temperature increase of a resin and catalyst mixture heated in a controlled bath, focusing on the . By defining exact test conditions-including resin sample size, heating rate, and catalyst type- enables consistent and reproducible comparisons of resin reactivity across different laboratories and manufacturers.
