Commissioning of electrical, instrumentation and control systems in the process industry - Specific ...
IEC 62337:2012 defines specific phases and milestones in the commissioning of electrical, instrumentation and control systems in the process industry. By way of example, it describes activities following the "completion-of-erection" milestone of the project and prior to the "acceptance-of-the-plant" phase by the owner. Such activities need to be adapted for each type of…
Tumble dryers for household use - Methods for measuring the performance
IEC 61121:2012 is applicable to household electric tumble dryers of the automatic and non-automatic type, with or without a cold water supply and incorporating a heating device. This excludes tumble dryers which use gas or other fuels as a heating source. The object is to state and define the principal performance characteristics of household electric tumble dryers of interest to users and to…

Information technology - Common Language Infrastructure (CLI)
ISO/IEC 23271:2012 defines the Common Language Infrastructure (CLI) in which applications written in multiple high-level languages can be executed in different system environments without the need to rewrite those applications to take into consideration the unique characteristics of those environments. It consists of six partitions.
Partition I describes the overall architecture of the CLI, and…
