Circular economy — Review of existing value networks
This document reviews the characteristics and structures of some existing value networks as examples in accelerating a circular economy transition process.
ISO 59010 gives guidance on a critical aspect in transitioning an organization’s business model and processes from linear to circular and transforming an organization’s business ecosystem into a value network. This document complements ISO…

Superconductivity - Part 23: Residual resistance ratio measurement - Residual resistance ratio of ca...
IEC 61788-23:2024 addresses a test method for the determination of the residual resistance ratio (RRR), rRRR, of cavity-grade niobium. This method is intended for high-purity niobium grades with 150 < rRRR < 600. The test method is valid for specimens with rectangular or round cross-section, cross-sectional area greater than 1 mm2 but less than 20 mm2, and a length not less than 10 nor more…

L'IEC 61788-23:2024 spécifie une méthode d'essai pour la détermination du rapport de résistance résiduelle (RRR), rRRR, du niobium à cavités. Cette méthode est destinée aux nuances de niobium de grande pureté de 150 < rRRR < 600. La méthode d'essai est valide pour des éprouvettes à sections rectangulaires ou circulaires, de surface de section supérieure à 1 mm2, mais…
