Standard Test Method for Insoluble Contamination of Hydraulic Fluids by Gravimetric Analysis
 N D4898

Annotation

This test method covers the determination of insoluble contamination in hydraulic fluids by gravimetric analysis. The contamination determined includes both particulate and gellike matter, organic and inorganic, which is retained on a membrane filter disk of pore diameter as required by applicable specifications (usually 0.45 ?m or 0.80 ?m).

To indicate the nature and distribution of the particulate contamination, the gravimetric method should be supplemented by occasional particle counts of typical samples in accordance with Test Method F312.

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. For a specific warning statement, see 6.1.

Стандартный метод испытаний для нерастворимого загрязнения гидравлических жидкостей весовым анализом

Этот метод тестирования покрывает определение нерастворимого загрязнения в гидравлических жидкостях гравиметрическим анализом. Определенное загрязнение включает и макрочастицу и подобный гелю вопрос, органический и неорганический, который сохраняется на мембранном диске фильтра диаметра поры как требуется применимыми спецификациями (обычно 0.45 m или 0.80 m).
