The third section of the revision survey switched to focusing on the perceived quality of a revision and satisfaction with a reviser’s job. But it kicked off with asking respondents whether they were aware of the definitions of reviser and revision in the standard ISO 17100:2015, and two thirds are apparently not.
It’s quite simple, really. A revision is the comparison of the source text and the target text (i.e the translation) by a second person, the reviser (and, therefore, revision does not refer to the check the translator makes of his/her own work).
