What is PD IEC/TR 62617 – Uncertainty reporting of measurements of laundry appliances about?
PD IEC/TR 62617 is a technical report on home laundry appliances that discusses uncertainty reporting of measurements to ensure efficient uncertainty reporting.
PD IEC/TR 62617 applies to uncertainty reporting of measurements of home laundry electrical appliances.
The provisions in PD IEC/TR 62617 can also be used to evaluate other kinds of products.
Who is PD IEC/TR 62617 – Uncertainty reporting of measurements of laundry appliances for?
PD IEC/TR 62617 on uncertainty reporting of measurements of laundry appliances are useful for:
- Laundry appliance manufacturers
- Installers of the electrical supply unit
- Product development teams/innovation teams
- Quality control personnel
Why should you use PD IEC/TR 62617 - Uncertainty reporting of measurements of laundry appliances?
To encourage the efficient use of energy and other resources, National governments and regional authorities have issued regulations, which mandate the provision of information to consumers regarding the energy and water consumption of household appliances and associated performance characteristics. This information is usually conveyed by labels attached to appliances at the point of sale and by brochures provided by manufacturers.
Methods for measuring declared values for energy and water consumption and performance characteristics need to be of sufficient accuracy to provide confidence to governments, consumers and manufacturers. PD IEC/TR 62617 assists in providing accuracy in measuring the values for energy and water consumption and performance by ensuring that the given data is interpreted correctly and accurately. The accuracy of a test method is expressed in terms of bias and precision. Precision, when evaluating test methods, is expressed in terms of two measurement concepts: repeatability and reproducibility.
PD IEC/TR 62617 allows you to estimate the uncertainty of a measured result and predict the range of values that may be measured when the same appliance is measured in another laboratory following the same measurement method. With compliance and obedience to PD IEC/TR 62617, you can efficiently measure the uncertainty of a measured result in the case of home laundry appliances.
