IEC 60230:2018 defines the procedure for carrying out withstand lightning and switching impulse tests and withstand superimposed impulse test on cables and their accessories.<br />
This document applies solely to the methods of carrying out the tests as such, independently of the problem of selecting the test levels to be specified. The voltages pertaining to the system on which cables and…
Anodizing of aluminium and its alloys — Method for specifying decorative and protective anodic oxida...
ISO 7599:2018 specifies a method for specifying decorative and protective anodic oxidation coatings on aluminium (including aluminium-based alloys). It defines the characteristic properties of anodic oxidation coatings, lists methods of test for checking the characteristic properties, provides minimum performance requirements, and gives information on the grades of aluminium suitable for…
Function blocks (FB) for process control and electronic device description language (EDDL) - Part 2:...
IEC 61804-2:2018 specifies FB (function blocks) by using the result of a harmonization work as regards several elements.
a) The device model which defines the components of an IEC 61804-2 conformant device.
b) Conceptual specifications of FBs for measurement, actuation and processing. This includes general rules for the essential features to support control, whilst avoiding details which stop…
Nuclear medicine instrumentation - Routine tests - Part 3: Positron emission tomographs
IEC TR 61948-3:2018(E) describes test methods for Positron Emission Tomographs (PET). As part of quality control, this document is defining routine tests to be performed by the user of Positron Emission Tomographs to maintain proper operation conditions. The results of these routine tests are compared to the reference data determined during or after acceptance test. Methods used for acceptance…
