Assembly tools for screws and nuts — Hand torque tools — Part 2: Requirements for calibration and de...
This document specifies the method for the calibration of hand torque tools and describes the method of calculation of measurement uncertainties for the calibration.
It also specifies the minimum requirements for a certificate of calibration to this standard for hand torque tools.
The Annex C of this document specifies the minimum requirements for the calibration of the torque measurement device…
Biotechnology — Cell counting — Part 1: General guidance on cell counting methods
ISO 20391-1:2018 defines terms related to cell counting for biotechnology. It describes counting of cells in suspension (generally cell concentration) and cells adhered to a substrate (generally area density of cells). It provides key considerations for general counting methods (including total and differential counting, and direct and indirect counting) as well as for method selection,…
Road vehicles — Vehicle to grid communication interface — Part 21: Common 2nd generation network lay...
The document specifies all common test cases to be applied to and correctly handled by EVs (EVCC) and EVSEs (SECC) implementing ISO 15118-20 that are independent of a particular charging type (AC, DC, ACD, WPT charging). The document considers the use cases defined in ISO 15118-1:2019
The test system will comprise:
- A simulated SECC to verify the correct behaviour of a real EVCC
- A simulated…
