Standard Test Method for Visual Evaluation of Gloss Differences Between Surfaces of Similar Appearance
N D4449
Annotation
This test method covers the visual evaluation of gloss differences of coating surfaces, using special types of lamps for illumination. It identifies six aspects or types of gloss that one may look for when using the lamp to assess gloss differences between surfaces. It describes the conditions for using the lamps to best identify small differences in each of the six types of gloss. Four levels of visual gloss differences are distinguished.
While this technique is useful for both weathered and unweathered specimens, it has not been applied to metallics.
The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Метод стандартной пробы для визуальной оценки различий в блеске между поверхностями подобного появления
Этот метод тестирования покрывает визуальную оценку различий в блеске поверхностей покрытия, с помощью специальных типов ламп для освещения. Это идентифицирует шесть аспектов или типы блеска, который можно искать при использовании лампы для оценки различий в блеске между поверхностями. Это описывает условия для использования ламп для лучшей идентификации небольших различий в каждом из шести типов блеска. Отличают четыре уровня визуальных различий в блеске.
