ISO/NP 6502-4 Rubber — Measurement of vulcanization characteristics using curemeters — Part 4: Part 4: Evaluation of reaction kinetics of crosslinking at isothermal and non-isothermal conditions

Scope

This document provides requirements for the determination of the vulcanization process of rubber mixes using curemeters and for the evaluation of cross-linking isotherms in terms of reaction kinetics.

Purpose

It is a tool for manufacturers to evaluate and control the curing process in rubber production as well as to reduce trial-and-error in determining optimal vulcanization times and temperatures and therefore it allows manufacturers to lower energy consumption by optimizing heating cycles. The proposed standard is based on German standard DIN 53529-2:1983-03 “Testing of rubber and elastomers; measurement of vulcanization characteristics (curometry); evaluation of cross-linking isotherms in terms of reaction kinetics” that has been further developped in order to present a generalized approach for kinetic calculations (Kamal-Sourour approach).
