Sensor systems should be designed and engineered according to generally binding standards and guidelines. The use of the new fiber-optic sensor (FOS) technology requires recommendations on how to design and apply a sensor system to solve a specific measurement task. At present, corresponding national or international standards and guidelines are being developed. When customers are interested in the use of FOS technology, a multitude of reliability-related aspects have to be considered. Guidelines help give the users confidence in this new technology if they are strictly observed during manufacturing of sensor system components, when the measurement systems are designed and sensor components are selected to solve a specific measurement task, during application and later on during operation of the sensor system. The article provides a survey on important aspects that have to be considered for the use of reliable and long-term stable SHM systems, reflects upon state of the art of standards and guidelines activities, besides summarizing validation aspects that have to be described in FOS guidelines. Important technical aspects that influence sensor characteristics and the accuracy, efficiency, and long-term integrity of a sensor system are exemplified for fiber-optic strain sensors. One test method to characterize strain transfer for applied sensor fibers is discussed.
