CEN/TC 352/WG 1 - Measurement, characterization and performance evaluation

This document specifies requirements and recommendations for the identification of measurands to characterize nano-objects and their agglomerates and aggregates, and to assess specific properties relevant to the performance of materials that contain them. It provides recommendations for relevant measurement.

This document specifies a method for measuring the scratch resistance and failure behaviour for advanced materials and coatings by means of nano- and micro- scale scratch experiments. The method provides data on both the physical damage to test-pieces and the friction generated between the probe and the test-piece under single pass and multiple pass conditions. The force range in these tests is from 1 μN up to 2 N.
The test method is not applicable to coatings as defined in EN ISO 4618 [18].

This Technical Specification provides a guidance for the responsible development of nanotechnologies taking into account:
-   Board Accountability;
-   Stakeholder Involvement;
-   Worker Health and Safety;
-   Benefits to and Risks for Public Health, Safety and the Environment;
-   Wider Social and Ethical Implications and Impacts;
-   Engagement with Business Partners;
-   Transparency and Disclosure.
NOTE 1   This Technical Specification contributes to social responsibility as defined in ISO 26000:2010.
NOTE 2   Nanotechnology activities include industrial production, R&D, services, and marketing of products.
This Technical Specification neither covers labelling and advertising aspects nor is it intended for certification purposes, nor does it imply any legally binding agreements.
This Technical Specification intends to cover nanotechnology activities involving manufactured nanomaterials, and where relevant incidental nanomaterials.

This Technical Specification provides guidelines for the identification of measurands to characterize nano-objects, and their agglomerates and aggregates and to assess specific properties relevant to the performance of materials that contain them. It provides guidance for relevant and reliable measurement.
