This document provides a measurement method to assess the reliability of washing machines for household use. This document defines the functional analysis, limiting events/states, environmental conditions and test conditions of washing machines. It also elaborates on the level of confidence on the measurement results. NOTE 1 The method is based on EN 45552 (General method for the assessment of the durability of energy-related products) and takes into account EN 45554 (General methods for the assessment of the ability to repair, reuse and upgrade energy-related products). This document provides information about the interrelations of reliability, repairability and upgradeability with consideration towards a durability assessment for washing machines for household use. This document provides input/results about the investigation on the assessment of repairability and upgradeability for washing machines for household use. This document is not intended to be used to assess the reliability of: - washing machines, intended for commercial or industrial use; - washer-dryers. NOTE 2 A testing method for washing machines unable to provide heated washing programmes have a low market relevance and will be considered in a future edition of this standard. This document does not address the ability of washing machines to be reused. Product functions related to the safety of washing machines are out of the scope of this document. NOTE 3 EN 60335-2-7 addresses safety requirements for household appliances. It includes aging tests that are relevant to safety. This document is intended to be used for the validation of a reliability declaration.
