IEC 63237-1:2022(Main)
Household and similar electrical appliances - Product information properties - Part 1: Fundamentals

IEC 63237-1:2022 provides a method for standardizing the descriptions of household electrical appliances.
The aims of this document are to:
- define a common language for customers and suppliers through the publication of classes, represented by properties and their attributes;
- enable electronic data exchange by machines (including information technology systems, see machine-to-machine communication [M2M]);
- optimize workflows between customers and suppliers, as well as in processes, such as engineering, development and purchasing within their own organizations;
- offer also a dictionary to legislators; and
- reduce transaction costs.
This document describes household electrical appliances using properties and makes the associated properties available in the IEC Common Data Dictionary (IEC CDD).
Furthermore, this document provides rules, methods and the generic data structure for product specific classification standards and on how to produce a reference dictionary based on the IEC 61360 series. This in turn creates a descriptive basis of company internal and external descriptions of household electrical appliances based on structured classes and lists of properties.

IEC 62301:2011(Main)
Household electrical appliances - Measurement of standby power

IEC 62301:2011 specifies methods of measurement of electrical power consumption in standby mode(s) and other low power modes (off mode and network mode), as applicable. It is applicable to electrical products with a rated input voltage or voltage range that lies wholly or partly in the range 100 V a.c. to 250 V a.c. for single phase products and 130 V a.c. to 480 V a.c. for other products. The objective of this standard is to provide a method of test to determine the power consumption of a range of products in relevant low power modes (see 3.4), generally where the product is not in active mode (i.e. not performing a primary function). This standard does not specify safety requirements. It does not specify minimum performance requirements nor does it set maximum limits on power or energy consumption. This second edition cancels and replaces the first edition published in 2005 and constitutes a technical revision. The main changes from the previous edition are as follows:
- greater detail in set-up procedures and introduction of stability requirements for all measurement methods to ensure that results are as representative as possible;
- refinement of measurement uncertainty requirements for power measuring instruments, especially for more difficult loads with high crest factor and/or low power factor;
- updated guidance on product configuration, instrumentation and calculation of measurement uncertainty;
- inclusion of definitions for low power modes as requested by TC59 and use of these new definitions and more rigorous terminology throughout the standard;
- inclusion of specific test conditions where power consumption is affected by ambient illumination.
