FINE WIRE MESH FOR FILTER ELEMENTS
1989-05-30
HISTORICAL
AIR888A
This AIR discusses the terminology, types, method of manufacture and chemistry of the fine wire meshes used for filtration of hydraulic, lubrication, fuel systems and similar applications. Information contained herein may be used for quality assurance testing to insure that a high performance filter grade wire mesh is acceptable for use in an aerospace application.

RECOMMENDED STANDARD FOR AEROSPACE FILTER ELEMENT FINE WIRE MESH
2011-02-11
HISTORICAL
AIR888
This AIR discusses the nature, method of manufacture and chemistry of fine wire meshes of the type used for filtration and similar applications, and how this information may be utilized in setting up a quality control program to insure reliability of meshes used for such applications.

Aerospace-Particle Count Data Conversion and Extrapolation
2012-09-24
CURRENT
AIR877C
This SAE Aerospace Information Report (AIR) describes a mathematical model that can be used to analyze particle count data. Particle counts that fit the model can be graphically displayed, converted from one counting size-frequency range to another, and extrapolated to estimate counts beyond the measured range. Derivation, applications, and calculations are described.

Procedure for the Determination of Particulate Contamination of Air in Dust Controlled Spaces by the Manual Particle Count Method
2001-03-01
HISTORICAL
ARP743B
This SAE Aerospace Recommended Practice (ARP) describes two procedures for sampling particles in dust controlled spaces. One procedure covers airborne dust above 5 μm. The other (and newly added procedure) covers particles of 25 μm and larger that “fall out” of the environment onto surfaces. In each case the particles are sized in the longest dimension and counted. Airborne particles are reported as particles per cubic meter (cubic foot) whereas particles collected in fall out samples are reported as particles per 0.1 square meter (square foot). This document includes English units in parentheses as referenced information to the SI units where meaningful. These procedures may also be used for environmental analysis where the quality of the particles by visual or chemical analysis is intended.

PROCEDURE FOR THE DETERMINATION OF PARTICULATE CONTAMINATION OF AIR IN DUST CONTROLLED SPACES BY THE PARTICLE COUNT METHOD
1962-08-30
HISTORICAL
ARP743
This test describes a self-checking procedure for the determination of particulate contaminant five microns or greater in size in air by the particle count method. A maximum variation of two to one (±33% of the average of two runs) in results should be expected for replicate counts on the same sample, providing that the procedure is followed closely and the precautions presented regarding check samples and self-checking aspects are observed.

Importance of Physical and Chemical Properties of Aircraft Hydraulic Fluids
2011-02-08
HISTORICAL
AIR81C
This document discusses the relative merits of the physical and chemical properties of hydraulic fluids in relation to the aerospace hydraulic system design, and the related materials compatibility. The discussion in this report applies both to hydrocarbon and phosphate ester based aircraft hydraulic fluids. In some cases, numerical limits are suggested, but, in general, the significance and effect of a property is noted qualitatively.
