Overall Methodology
Durability and Product Lifetime
The main objective of WP 3 in the project PROMPT is to analyse scientifically an approach to reliability testing that can be addressed from an end users perspective when the product is put on the market. For example a smartphone will need to survive a range of different drops on the floor. In this case a tumble drop test can mimic this situation. In order to be relevant, such a test needs a detailed scope and specification. The approach to develop such test specifications is focussed around four product groups (washing machines, vacuum cleaners, smartphones, TVs) and explained in the reports given in this section.

This report gives an overview on the methodology to develop tests for reliability and durability. It focusses on the considerations to be done in the set-up of a test program from the perspective of a consumer organization or market surveillance authority. In this situation, reliability is to be assessed, when the product is placed on the market. Relevant results from the PROMPT project are summarized, which are focused around the analysed product groups. In order to enable the transfer of results to other relevant product groups and aspects a generalization is being discussed. Finally a generalized procedure for test and mission profile development is suggested.
Please note, that this is a preliminary version of the deliverable and might be subject to changes after the periodical review as part of the H2020 review process.

Four consumer product groups (Vacuum cleaners, washing machines, mobile phones and television sets) have been analysed in regard to the current state of durability assessment. The dominant failures have been determined and compared to the current test programs. Gaps in current tests as well as requirements for tests to close these gaps have been identified.
