ISO/TC 256/WG 2 develops ISO standards in the area of Information technology. Currently, there are 2 published standards from this working group.

The International Organization for Standardization (ISO) is an independent, non-governmental international organization that develops and publishes international standards. Founded in 1947 and headquartered in Geneva, Switzerland, ISO brings together experts from 170+ member countries to share knowledge and develop voluntary, consensus-based standards that support innovation and provide solutions to global challenges.

A Working Group in ISO is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.

Pigments and extenders - Determination of experimentally simulated nano-object release from paints, varnishes and pigmented plastics

This document specifies a method for experimental determination of the release of nanoscale pigments and extenders into the environment following a mechanical stress of paints, varnishes and pigmented plastics. The method is used to evaluate if and how many particles of defined size and distribution under stress (type and height of applied energy) are released from surfaces and emitted into the environment. The samples are aged, weathered or otherwise conditioned to simulate the whole lifecycle.
