Immerse the specimens in hydraulic f

13、luid (see 6.3) in a manner that the fluid completely surrounds the specimens and that no specimen touches any other specimen or the sides of the container.

15、 3.5 Particle count determination. A sample of new hydraulic fluid conforming to MIL-PRF-5606 shall be filtered through a 0.8 micrometer cellulose ester membrane filter, followed by filtration through a 0.45 micrometer cellulose ester membrane filter. The filtered hydraulic fluid shall then be place

16、d in a 1-liter container. The quantity of oil used shall be such that with the cloth immersed in it, the free space above the oil level shall be not less than 20 percent nor more than 30 percent of the container volume. The container shall be stoppered with a non-shedding plastic film and agitated f
