The objective of this chapter is to demonstrate the extent to which quality standards affect revision practice among translation service providers (TSPs) in Austria. The introduction will offer an overview of different standards developed for TSPs, with a special focus on recommendations for reviewing translations and for other-revision, which has become an essential element of quality assurance in translation, especially since the publications of EN 15038 in 2006 and ISO 17100 in 2015. A second section will consider the possibilities of standard-based certification and registration and describe the difference between these two processes. The main part of the paper will present the results of an online survey conducted in 2015 and an interview-based study conducted in 2016 regarding the acceptance of certification and registration among TSPs in Austria. It will then examine whether, according to participants in the study, other-revision is compulsory in their practice and address the rate of acceptance and application of EN 15038/ISO 17100. The results show that two-thirds of the certified companies revise every translation whereas almost three-quarters of the uncertified companies that claim to work in line with EN 15038 do so. And a large majority of the certified companies works with revision parameters. Considering all the aspects investigated, EN 15038 and ISO 17100 seem to have an influence on the professional activities of TSPs.
