ISO 26362:2009 specifies the terms and definitions, as well as the service requirements, for organizations and professionals who own and/or use access panels for market, opinion and social research. It develops the criteria against which access panel providers can be evaluated and against which the quality of access panels can be assessed. ISO 26362:2009 is applicable to all types of access panels, whether recruited and used online (e.g. via internet) or offline (e.g. via telephone, post or face-to-face interaction).
