Rubber and rubber products — Determination of biobased content Part 2: Biobased carbon content Published (Edition 2, 2025)

Abstract

This document specifies measuring methods for the determination of biobased carbon contents in rubber and rubber products, including polyurethanes. The methods focus on carbon atoms in rubber or rubber products, and determine whether the carbon-containing component is biobased or not, judging from the concentration of ¹⁴C, radiocarbon isotope.

This document applies to rubber and rubber products such as raw materials, materials and final products.
