适用范围

  Full Description ADOPTED_FROM:EN ISO 18490:2015 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.
