Non-destructive Testing - Evaluation of vision acuity of NDT personnel (ISO 18490:2015)
ISO 18490:2015 specifies the form of the optotype, the quality requirements for the chart, 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.
ISO 18490:2015 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.
ISO 18490:2015 does not address colour vision requirements.
Zerstörungsfreie Prüfung - Bestimmung der Sehfähigkeit von ZfP-Personal (ISO 18490:2015)
In dieser Internationalen Norm werden die Gestalt der Sehzeichen (Optotypen), Qualitätsanforderungen an die Sehprobentafel, das Prüfverfahren und die Kriterien für die akzeptierbare Nahsehschärfe des Personals für die ZfP festgelegt. Ebenfalls erfasst werden Anforderungen an die Qualifikation des Personals, das zur Durchführung der Prüfung befugt ist.
Diese Internationale Norm behandelt lediglich die Nahsehschärfe unter festgelegten Bedingungen, die den Bedingungen bei einer routinemäßigen zerstörungsfreien Prüfung entsprechen. Nicht behandelt wird die Gesamt-sehschärfe einer bestimmten Person; den Anwendern wird empfohlen zu überlegen, ob eine allgemeine Augenuntersuchung durch spezialisiertes medizinisches Personal notwendig ist um sicherzustellen, dass die allgemeine Sehschärfe für die Arbeitsaufgabe ausreichend ist.
In dieser Internationalen Norm werden keine Anforderungen an das Farbsehvermögen behandelt.

Neporušitvene preiskave - Vrednotenje ostrine vida za osebje, ki izvaja neporušitvene preiskave (NDT) (ISO 18490:2015)
Ta dokument določa obliko optotipa, preskusnega postopka in ravni sprejemljivosti za vrednotenje ostrine vida za osebje, ki izvaja neporušitveno preskušanje (NDT). Obravnava tudi zahteve glede usposobljenosti za osebje, ki lahko izvaja preskus. Ta standard obravnava samo vrednotenje ostrine vida pri določenih pogojih, ki so podobni tistim med rutinskim vrednotenjem osebja NDT. Standard ne obravnava celovite ostrine vida in uporabnikom se svetuje, naj razmislijo o potrebi po splošnem pregledu oči pri specializiranem zdravniškem osebju za zagotovitev splošne ostrine vida, ki je ustrezna za funkcijo delovnega mesta. Ta dokument ne obravnava zahtev za razlikovanje barv.

Introduction
Standards for NDT Personnel qualification and certification require that the visual acuity of inspection
personnel is verified as being appropriate to their function. By meeting the near vision acuity level
defined in this International Standard, such requirements of ISO 9712 and EN 4179 will be met. The
purpose of this International Standard is to provide a detailed, standardised procedure for the evaluation
of near vision acuity for such personnel under defined lighting conditions.
The test is not medical in nature and is intended to objectively ensure adequate near vision perception
without reliance on reading ability or text identification. Because it is extremely difficult to demonstrate
any equivalency in near vision tests, this International Standard has been prepared in order that an
international system may be used without any need to demonstrate equivalence and is the recommended
method of determining near vision acuity for NDT Personnel.
