The method presented is the current recommendation for the use of flame ionization detectors to determine the hydrocarbon content of diesel engine exhaust, or exhaust of vehicles using diesel engines, when operating at steady-state. The requirements of the associated sampling system and a general procedure for a continuous measuring method are presented. This SAE Recommended Practice provides for the continuous measurement of the hydrocarbon concentration in diesel exhaust.

J986A_197009
This SAE Standard establishes the test procedure, environment, and instrumentation for determining the exterior sound level for passenger cars, multipurpose vehicles, and light trucks having a gross vehicle mass rating of 4540 kg or less. The test procedure is characterized by having fixed initial conditions, i.e., an as-specified initial vehicle speed and gear selection at a fixed start point on the test site. Full-throttle acceleration and closed-throttle deceleration of the vehicle are included in this procedure. Sound levels determined in accordance with this document are dependent on the performance capability of the test vehicle, as influenced by power-to-mass ratio and overall powertrain gear ratio.

ARP695A
This Aerospace Recommended Practice provides design and installation criteria intended to enhance overall safety by mitigating exposure of cabin crew and passengers to risks from: a. Routine use of galley systems. b. Galley components or equipment becoming dislodged under routine or abnormal operating conditions and under survivable crash or ditching conditions. c. Malfunctions of, or defects in, a galley system or associated galley equipment. NOTE: It is not the purpose of this Aerospace Recommended Practice to specify the specific designs or design methods to be followed in the accomplishment of stated objectives.

J177_197006
The method presented applies to the analysis of the indicated constituents in diesel engine exhaust, or vehicles using diesel engines, when operating at steady-state conditions. The measurements of carbon monoxide, carbon dioxide, and nitric oxide are based on continuous sampling and analysis by nondispersive infrared (NDIR) methods. Measurement of total oxides of nitrogen by chemiluminescence and NDIR methods is discussed. This SAE Recommended Practice provides for the measurement of carbon dioxide, carbon monoxide, and oxides of nitrogen in diesel exhaust.

This Aerospace Recommended Practice (ARP) standardizes test equipment and procedures for the measurement of smoke emission from aircraft gas turbine engines. The procedures included are for determining and reporting the amount of smoke emission. Tests have indicated that the practically achievable precision of the smoke number is within ±3 when the system is properly used as outlined herein. This procedure is not intended for in-flight testing, nor does it apply to afterburning mode.

This recommended practice establishes objectives for high performance control motor tachometer generators to be used with aeronautical and associated equipment in protective enclosures or completely within the shell of the aircraft so that they are subjected only to the internal climatic conditions of heat, cold, shock, vibration, and humidity. Control motor tachometer generators larger than size 23 are not covered in this document.

The scope of this HIR is to specify general oceanographic environments. Specific environmental requirements shall be specified in a detail specification. Specific requirements are in the state of constant flux because the ocean environment is constantly changing and the changes occur not only on a seasonal basis but also monthly, weekly, daily, and in some cases even hourly. This HIR is to be used as a guide only.

ARP958
This SAE Aerospace Recommended Practice (ARP) outlines a standard method for the checkout and calibration of electromagnetic interference measurement antennas. Its primary application is for use when measuring a source 1 m from the antenna in a shield room versus a source at a greater distance (far field). This is the typical distance used in performing military EMC testing. Thus, this is a method of calibration. Shield room characteristics are not considered. It does not address an unknown distributed source. Yet it is close to reality since it is based on another antenna that represents a distributed source. This document presents a technique to determine antenna factors for antennas used primarily in performing measurements in accordance with 2.1 and 2.2. The purpose of Revision B is to include the calibration of other antennas, such as small loop antennas that are also specified for use in these same references.

The purpose of this SAE STandard is to provide standard test procedures for crankcase emission control systems and/or devices. The procedures included are for determining: a. The flow rate of the blowby of an engine; b. The flow rates through the crankcase emission control system inlet and outlet. This code is written to cover crankcase emission control systems which are designed to reduce the emission of engine blowby gases to the atmosphere. The code includes the following sections: 3. Definitions and Terminology; 4. Test Equipment; 5. Test Procedures; 6. Information and Data to be Recorded; 7. Data Analysis; 8. Presentation of Information and Data.

INTRODUCT ION Conventional internal conbustion a i r c r a f t engines require the same basic conditions for starting in cold weather as they do in warn weather. These are: (1) The engine must be cranked a t a reasonable speed. ( 2 ) A combustible mixture must be delivered t o the cylinders. (3) An ignition spark must be supplied which is capable of igniting t'ne charge a t the proper t i m e . (4) The fits and olearanoes of mating parts in the engine m u s t be such that normal Sunctions occur a t a l l temperatures. (5) The engine must receive a usable lubricant. (6) The engine must develop s u f f i c i e n t power t o overcome its own f r i c t i o n and accelerate itself t o the desired operating speed.
