Mechanical vibration — Measurement and evaluation of machine vibration — Part 3: Industrial machiner...
This document specifies the general requirements for evaluating the vibration of various coupled industrial machine types with a power above 15 kW and operating speeds between 120 r/min and 30 000 r/min when measurements are made in-situ. Guidelines for applying evaluation criteria are provided for measurements taken on non-rotating and rotating parts under normal operating conditions. The…
Systems and software engineering — Life cycle management — Part 8: Technical reviews and audits on d...
This document establishes the requirements for technical reviews and audits to be performed throughout the acquisition life cycle for the US Department of Defense (DoD) and other defense agencies. This document provides the definition, description, and intent, as well as the entry, exit and success criteria, for each technical review and audit. It is to be used to establish agreement between…
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…
Lasers and laser-related equipment — Test methods for laser-induced damage threshold — Part 1: Defin...
ISO 21254-1:2011 defines terms used in conjunction with, and the general principles of, test methods for determining the laser-induced damage threshold and for the assurance of optical laser components subjected to laser radiation.
Water quality — Estimation of measurement uncertainty based on validation and quality control data
This International Standard specifies methods for the estimation of measurement uncertainty of chemical and
physicochemical methods in single laboratories based on validation data and analytical quality control results
obtained within the field of water analysis.
NOTE 1 The principles of the estimation of uncertainty specified in this International Standard are consistent with the
principles…
