Standard Test Method for Measurement of Lubricant Generated Insoluble Color Bodies in In-Service Turbine Oils using Membrane Patch Colorimetry
N D7843
Annotation
This test method extracts insoluble contaminants from a sample of in-service turbine oil onto a patch and the color of the membrane patch is analyzed by a spectrophotometer. The results are reported as a ?E value, within the CIE LAB scale.
This test method is not appropriate for turbine oils with dyes.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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.
*A Summary of Changes section appears at the end of this standard

Стандартный Метод испытаний для Измерения Смазки Сгенерированные Нерастворимые Вещества, обусловливающие цветность в Штатных Турбинных маслах с помощью Мембранной Колориметрии Участка
Этот метод тестирования извлекает нерастворимые загрязнители из образца штатной турбинной нефти на патч, и цвет мембранного патча проанализирован спектрофотометром. О результатах сообщают, поскольку E оценивает в CIE масштаб LAB.
