This document addresses a blockchain-based traceability platform for cold chain food which realizes continuous and effective tracking of the cold chain food. The following aspects are included: —    it explores issues and considerations for cold chain food traceability, especially during the epidemic outbreak; —    it describes scenarios and stakeholders for effective tracking of the cold chain…

These international guidelines are based on the assumption that monitoring of environmental components (atmosphere, water, soil and biota) as well as food quality is performed to ensure the protection of human health[5][7][8][9][10][11][12]. The guidelines constitute a basis for the setting of national regulations, standards, and inter alia, for monitoring air, water and food in support of public…

IEC 62044-3:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62044-3:2023 specifies measuring methods for power loss and amplitude permeability of magnetic cores forming the…

IEC 60383-1:2023 applies to insulators of ceramic material or glass for use on AC overhead power lines and overhead traction lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It also applies to insulators for use on DC overhead electric traction lines. This document applies to string insulator units, rigid overhead line insulators and to insulators of…
