Reaching long-term stability in cp-φotdr
WebLong-term drift, and the required tests connected with it, are specified in the EN 61298 standard. The long-term stability is defined in DIN 16086. How do long-term drift and long-term stability differ? With long-term drift, in accordance with EN 61298-2, chapter 7.2, a pressure value of 90 % of the measuring span must be maintained for 30 days. WebSince the catalysts used commercially need work for long-time stability at the same voltage or current density, the CA and CP curves are mainly referred to in the following details of the HER catalyst stability progress. 1, 61, 62 Meanwhile, new methodologies are now emerging to assess the stability of catalysts, such as flow cell–inductively ...
