You probably reached this page by following the link in the Appendix at the end of ASTM F2575, either the 2023 or 2025 edition, seeking further information about Grades (see section 5.3) or Labels (see section 10.2). In case you got here some other way, here is that link:

The term “translation grades” never really caught on after the publication of the 2023 edition of F2575, and the translation labels BRT (Bilingually Reviewed Translation) and UMT (Unedited Machine Translation), also introduced in the 2023 edition, were found to be less than optimal. However, the labels Professionally Verified Translation and Unverified Translation in section 10.2 of the 2025 edition are gathering some momentum. Several presentations have been made about them in various corners of the translation world.
The 2025 text of section 10.2 of F2575, which introduces these labels, reads as follows (omitting the final sentences, which are not relevant):
As a matter of transparency and consumer protection, stakeholders should label translation output as either “unverified translation” or “professionally verified translation.” The word “professionally” emphasizes that a professional – a qualified translator who has all the competencies mentioned in subsection 7.4 above (cf. ISO 17100:2015 subsection 3.1) – has produced and self-checked, edited, or revised (that is, verified) the translation, confirming that it meets the agreed-on specifications and is thus a quality translation. Any translation that is not professionally verified is considered unverified. After labeling, the translations are released for use.
The connection between the grades in section 5.3 and the labels in section 10.2 is not obvious. A high-grade translation could merit the label Professionally Verified Translation, but grades are only about levels of correspondence and fluency. There is no requirement that a human, let alone a qualified professional, be involved in producing a high-grade translation. Also, a grade is selected during pre-production, but labels are assigned during the post-production phase. Grades will likely be refined or removed from the next major edition of F2575 if they have not found traction within the translation industry by then.
