Abstract
Suppose we consider the weighting of objects on a scale missing its spring. An object is placed on the scale and its weight is measured. The ”needle” indicated the correct weight but does not return to zero when the object is removed. If various objects are placed on the scale, only the weights greater than the previous can be recorded. These recorded weights are upper record value sequence. Let us consider a sequence of products that may fail under stress.
