Standard Test Method for Measuring the Night Vision Goggle-Weighted Transmissivity of Transparent Parts
 N F1863

Annotation

This test method covers apparatuses and procedures that are suitable for measuring the NVG-weighted transmissivity of transparent parts including those that are large, thick, curved, or already installed. This test method is sensitive to transparencies that vary in transmissivity as a function of wavelength.

Since the transmissivity (or transmission coefficient) is a ratio of two radiance values, it has no units. The units of radiance recorded in the intermediate steps of this test method are not critical; any recognized units of radiance (for example, watts/m2-str) may be used, as long as it is consistent.2

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Стандартный метод испытаний для измерения ночного видения взвешенная изумленным взглядом проницаемость прозрачных частей

Этот метод тестирования покрывает аппараты и процедуры, которые подходят для измерения NVG-взвешенной проницаемости прозрачных частей включая тех, которые являются большими, толстыми, изогнуты, или уже установленные. Этот метод тестирования чувствителен к диапозитивам, которые варьируются по проницаемости как функция длины волны.
