The purpose of this document is to specify the ISO/IEC 29197 testing methodology for European ABC systems. This specification will cover the following aspects:-environmental conditions which influence biometric modalities used for European ABC systems, i.e. temperature, humidity, illumination and noise;-different tests that can be defined regarding European ABC systems and the procedures for defining of the evaluation conditions to analyse per each test;-particular characteristics of European ABC systems in accordance to best practice recommendations and privacy and data protection regulations for this kind of systems in case of European deployments.As a consequence, the proposed document will include the following aspects:-specific requirements for planning and executing environmental testing evaluations for European ABC systems based on ISO/IEC 29197 project and the best practices recommendations provided by CEN/TS 16634 Personal identification — Recommendations for using biometrics in European Automated Border Control document;-recommendations for the selection of the possible tests according to the specific system that is going to be evaluated;-specific requirements to establish and measure such evaluation conditions as well as to establish the baseline performance;-a specification of the biometric performance evaluation including requirements for test population, test protocols, data to record and test results consistent with operational deployments of European ABC systems.
