Subject: Simulated vision test and distance Добрый день!Речь идёт о проверке зрения дефектоскопистов. Прошу помочь с переводом выделенной фразы. Do the records provide evidence that the near vision examinations meet one of the following? • Jaeger No 1 at not less than 12 inches (30.48 cm)* *With at least one eye, either natural or corrected. For NAS410 Rev 5, Simulated vision test and distance is not permitted. |

Non-destructive testing (NDT) is a critical commodity for military and commercial aviation and other industries for detection of potential defects, cracks and other irregularities of virtually every part of the aircraft from the outer structures to the core airframe and propulsion systems. NAS410 is a global, cornerstone standard for necessary qualification and certification of NDT personnel developed by AIA. A complete revision of NAS410 will be published on September 30th, 2020 and is available exclusively from IHS Markit. Subscription customers are alerted and automatically receive revision 5. Я так понимаю "симуляция теста и расстояния". |

TABLE V: VISION REQUIREMENTS EXAMINATION REQUIREMENTS Near vision (Select one) - TUMBLING E as per ISO 18490 - or SNELLEN 20/25 at a distance of 41 cm +2/-3 cm* - or JAEGER No. 1 at a distance of at least 30.5 cm* Colour perception Personnel must be able to distinguish and differentiate between the colours used in the applicable process. Tests advised: Full ISHIHARA or FARNSWORTH D15 *In at least one eye, natural or corrected. Simulated vision test and distance is not permitted. IMHO я бы сформулировал как-нибудь так — неврачебная проверка и нарушение указанных расстояний не допускаются |
