Non-destructive testing - Evaluation of vision acuity of NDT personnel (ISO 18490:2026)
Scope: This document specifies quality requirements for the chart, test procedure and acceptance level for near, far, and colour vision acuity of NDT personnel. Information for grey scale perception and low contrast can be found in the annexes. This document also specifies the qualification requirements for personnel permitted to carry out the test.
This document is only applicable to vision acuity under defined conditions similar to those encountered during routine NDT inspection. This document does not address an individual’s overall visual acuity and users are advised to consider the need for a general eye examination by specialist medical personnel to ensure general vision acuity.

Non-destructive testing — Equipment for eddy current examination — Part 1: Instrument characteristics and verification
Scope: This document specifies the characteristics of general-purpose eddy current instruments and provides methods for their evaluation and verification.
This document can be completed by an application document specifying acceptance criteria for the characteristics of the eddy current instrument.
Where accessories are used, these are characterized using the principles of this document (e.g. additional external amplifiers).

ISO 15548-1:2013
Non-destructive testing -- Equipment for eddy current examination -- Part 1: Instrument characteristics and verification
Scope: ISO 15548-1:2013 identifies the functional characteristics of a general-purpose eddy current instrument and provides methods for their measurement and verification.
The evaluation of these characteristics permits a well-defined description and comparability of eddy current equipment.
By careful choice of the characteristics, a consistent and effective eddy current examination system can be designed for a specific application.
Where accessories are used, these are characterized using the principles of ISO 15548-1:2013.
ISO 15548-1:2013 gives neither the extent of verification nor acceptance criteria for the characteristics. They are given in the application documents.

Non-destructive Testing - Evaluation of vision acuity of NDT personnel (ISO 18490:2015)
Scope: This document specifies the form of the optotype, the test procedure and the acceptance level for near vision acuity of NDT personnel. It also addresses the qualification requirements for personnel permitted to carry out the test.
This standard only addresses near vision acuity under defined conditions similar to those encountered during routine NDT inspection. It does not address an individual’s overall visual acuity and users are advised to consider the need for a general eye examination by specialist medical personnel to ensure general vision acuity is appropriate for job function.
This document does not address colour vision requirements.
