As of the publication of this article, the status of the 2018 edition is "International Standard under systematic review" (Stage code 90.20). This periodic systematic review is a standard part of the ISO process, and it does not necessarily mean a new revision is imminent. However, it is always prudent for users of any standard to stay informed of its status.
The defining feature of the ISO 5948 standard is its classification of defect severity. Detected echoes that exceed a predetermined recording threshold must be evaluated. Flaws are typically categorized and assessed based on: Unofficial copies may be outdated or incomplete, potentially
