Plastics - Carbon and environmental footprint of biobased plastics - Part 2: Material carbon footprint, amount (mass) of CO2 removed from the air and incorporated into polymer molecule (ISO 22526-2:2020)

This document defines the material carbon footprint as the amount (mass) of CO2 removed from the air and incorporated into plastic, and specifies a determination method to quantify it.
This document is applicable to plastic products, plastic materials and polymer resins that are partly or wholly based on biobased constituents.

Polimerni materiali - Ogljični in okoljski odtis polimernih materialov na biološki osnovi - 2. del: Ogljični odtis materialov, količina (masa) CO2, odstranjena iz zraka in vključena v molekulo polimera (ISO 22526-2:2020)

Ta dokument opredeljuje ogljični odtis materiala kot količino (maso) CO2, odstranjeno iz zraka in dodano polimernemu materialu, ter določa metodo določanja za njegovo količinsko opredelitev.
Ta dokument se uporablja za izdelke iz polimernih materialov, polimerne materiale in polimerne smole, ki so delno ali v celoti osnovani na bioloških sestavinah.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
