A Review of Literature on the Relationship Between Gas Turbine Engine Lubricants and Aircraft Cabin Air Quality
2016-09-12
CURRENT
AIR5784
There has been a recent upsurge in interest from the media concerning the quality of the environment within aircraft cabins and cockpits especially in the commercial world1-4. This has included (although by no means been limited to) the air quality, with particular reference to the alleged effects of contamination from the aircraft turbine lubricant. Possible exposure to ‘organophosphates’ (OPs) from the oil has raised special concerns from cabin crew. Such is the concern that government organisations around the world, including Australia, USA and UK, have set up committees to investigate the cabin air quality issue. Concern was also voiced in the aviation lubricants world at the way in which OP additives in turbine lubricants were being blamed in some reports for the symptoms being experienced by air crew and passengers. SAE Committee E-34 therefore decided that it should gather as much available information on the subject as possible.

A/C Compressor Oil Separator Effectiveness Test Standard
2019-07-15
CURRENT
J3112_201907
This SAE Standard establishes the test conditions and reporting method for quantifying refrigerant circuit oil circulation rate (OCR) reduction effectiveness of mobile air conditioning compressors using R-134a and R-1234yf refrigerants that include oil separators and/or other design features for the purpose of reducing the OCR in the refrigerant circuit. This standard and the OCR values it produces are not intended to make judgement on suitability of OCR values with regard to compressor durability.

ACOUSTICAL AND THERMAL MATERIALS TEST PROCEDURE
1989-10-01
HISTORICAL
J1324_198910
This SAE Recommended Practice provides test methods for determining the characteristics of acoustical and thermal materials. Where applicable, methods of test developed by SAE and ASTM have been referenced.

AEROSPACE - DYNAMIC TEST METHOD FOR DETERMINING THE RELATIVE DEGREE OF CLEANLINESS OF THE DOWNSTREAM SIDE OF FILTER ELEMENTS
1996-05-01
HISTORICAL
ARP599B
This SAE Aerospace Recommended Practice (ARP) describes a procedure for determining the insoluble contamination level of the downstream side of filter elements. Results of this procedure represent the particulate released from the tested filter element under the prevailing conditions of the test. The results may be used for comparative evaluation of the effectiveness of various cleaning methods or the cleanliness of elements after cleaning or as received from manufacturers.

AEROSPACE - HYDRAULIC SYSTEM FLUID CONTAMINATION - LOCATION OF SAMPLING POINTS
1989-10-01
HISTORICAL
ARP4268
The scope of this Aerospace Recommended Practice (ARP) covers where, when, and how often to sample hydraulic system fluid on aerospace vehicles for particulate contamination measurements. The measurement of hydraulic fluid particulate contamination is of concern to the aerospace community because of the critical importance of hydraulic equipment reliability. Contamination is always present in the system fluid, even in new unused fluid. Contamination must be below a level that will not adversely affect system operation. This ARP draws from aerospace industry experience and practice to establish criteria for fluid contamination sampling recommendations in aerospace vehicle hydraulic systems. Fluid samples can then be subjected to measurement of particulate contamination and of other harmful contaminants such as chlorinated solvents and water.

AEROSPACE-PARTICLE COUNT DATA CONVERSION AND EXTRAPOLATION
1993-03-02
HISTORICAL
AIR877A
This 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.
