Improving reliability in experiments

Witryna7 lip 2024 · There are two suggested ways to measure rate of reaction when changing concentration. The first is to measure how quickly a precipitate is formed by observing the ‘cloudiness’ of a liquid. The second is to measure the volume of gas produced using a gas syringe or a measuring cylinder over water. WitrynaReliability can be deflned as quality over time [4], and therefore in reliability improvement experiments we need to study the performance of the product over time as opposed to just measuring the quality at a flxed point of time. Two types of data are usually gathered in reliability experiments: lifetime data, and degradation data.
