Standard Hydrogen Test Protocols for the NREL Sensor Testing Laboratory (Brochure)

PDF Version Also Available for Download.

Description

This brochure summarizes the test protocols used in the NREL Hydrogen Sensor Test Laboratory for the quantitative assessment of critical analytical performance specifications for hydrogen sensors. Researchers at the NREL Hydrogen Safety Sensor Test Laboratory developed a variety of test protocols to quantitatively assess critical analytical performance specifications for hydrogen sensors. Many are similar to, but typically more rigorous than, the test procedures mandated by ISO Standard 26142 (Hydrogen Detector for Stationary Applications). Specific protocols were developed for linear range, short-term stability, and the impact of fluctuations in temperature (T), pressure (P), relative humidity (RH), and chemical environment. Specialized tests ... continued below

Description

This brochure summarizes the test protocols used in the NREL Hydrogen Sensor Test Laboratory for the quantitative assessment of critical analytical performance specifications for hydrogen sensors. Researchers at the NREL Hydrogen Safety Sensor Test Laboratory developed a variety of test protocols to quantitatively assess critical analytical performance specifications for hydrogen sensors. Many are similar to, but typically more rigorous than, the test procedures mandated by ISO Standard 26142 (Hydrogen Detector for Stationary Applications). Specific protocols were developed for linear range, short-term stability, and the impact of fluctuations in temperature (T), pressure (P), relative humidity (RH), and chemical environment. Specialized tests (e.g., oxygen requirement) may also be performed. Hydrogen safety sensors selected for evaluation are subjected to a thorough regimen of test protocols, as described. Sensor testing is performed at NREL on custom-built sensor test fixtures. Environmental parameters such as T, P, RH, and gas composition are rigorously controlled and monitored. The NREL evaluations are performed on commercial hydrogen detectors, on emerging sensing technologies, and for end users to validate sensor performance for specific application needs. Test results and data are shared with the manufacturer or client via summary reports, teleconference phone calls, and, when appropriate, site visits to manufacturer facilities. Client representatives may also monitor NREL's operation while their technologies are being tested. Manufacturers may use test data to illustrate the analytical capability of their technologies and, more importantly, to guide future developments. NREL uses the data to assess technology gaps and deployment considerations. Per NREL Sensor Testing Laboratory policy, test results are treated as proprietary and are not shared with other manufacturers or other entities without permission. The data may be used by NREL in open publications (journal articles, presentations, outreach support, and other reports), but will not be attributed to a specific vendor.
