DIN ISO 16331-1:2018-10

Starting in 1993, several companies developed handheld laser distance meters and introduced them into the market. With a growing number of different manufacturers, it became obvious that a standard was needed to establish requirements for device specifications and to describe how to check compliance with the specified performance of accuracy and range. ISO 17123 specifies methods of checking specification compliance by the user of the instrument without any additional measurement equipment. In contrast, ISO 16331 specifies procedures to check specification compliance using additional laboratory equipment that is unavailable to the typical user.
