DIN SPEC 91368:2017-12

This DIN SPEC has been drawn up by a temporary body ('Workshop') in accordance with the PAS procedure. This DIN SPEC has been developed and adopted by the authors named in the Foreword. This DIN SPEC describes and determines the quality criteria and documentation requirements that are to be observed in connection with samples when conducting scientific surveys in market, opinion and social research. It includes quality criteria and documentation requirements that can be used for any data acquisition mode and survey target group but also such criteria and requirements that are specific to certain acquisition modes and target groups. Additional quality criteria and documentation requirements relevant for specific areas of research should refer to and build on this DIN SPEC, but are not themselves the subject of the document.
