Abstract
A method and a device for acquiring performance quantities of a product, in particular until its technical failure, and for determining the remaining service life of the product are described. The determination of the remaining service life of the product, acquisition of service lives of the products and determination of service life threshold values are performed on the basis of performance quantities subdivided into classes (classified). Weighting factors are determined first and then these weighting factors are used to determine weighted, cumulative service lives and service life threshold values. The reliability of products is monitored in mass production.
