  "Description": "The production of certified reference materials (CRMs)\nrequires various statistical tests depending on the task and\nrecorded data to ensure that reported values of CRMs are\nappropriate. Often these tests are performed according to the\nprocedures described in 'ISO GUIDE 35:2017'. The 'eCerto'\npackage contains a 'Shiny' app which provides functionality to\nload, process, report and backup data recorded during CRM\nproduction and facilitates following the recommended\nprocedures. It is described in Lisec et al (2023)\n<doi:10.1007/s00216-023-05099-3> and can also be accessed\nonline <https://apps.bam.de/shn00/eCerto/> without package\ninstallation.",
