ASTM D5001-10(2014)

Standard Test Method for Measurement of Lubricity of Aviation Turbine Fuels by the Ball-on-Cylinder Lubricity Evaluator (BOCLE)

SIGNIFICANCE AND USE
5.1 Wear due to excessive friction resulting in shortened life of engine components such as fuel pumps and fuel controls has sometimes been ascribed to lack of lubricity in an aviation fuel.  
5.2 The relationship of test results to aviation fuel system component distress due to wear has been demonstrated for some fuel/hardware combinations where boundary lubrication is a factor in the operation of the component.  
5.3 The wear scar generated in the ball-on-cylinder lubricity evaluator (BOCLE) test is sensitive to contamination of the fluids and test materials, the presence of oxygen and water in the atmosphere, and the temperature of the test. Lubricity measurements are also sensitive to trace materials acquired during sampling and storage. Containers specified in Practice D4306 shall be used.  
5.4 The BOCLE test method may not directly reflect operating conditions of engine hardware. For example, some fuels that contain a high content of certain sulfur compounds can give anomalous test results.
SCOPE
1.1 This test method covers assessment of the wear aspects of the boundary lubrication properties of aviation turbine fuels on rubbing steel surfaces.  
1.1.1 This test method incorporates two procedures, one using a semi-automated instrument and the second a fully automated instrument. Either of the two instruments may be used to carry out the test.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address 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.

In this test method, the lubricity of a fluid is defined in terms of a wear scar, in millimeters, produced on a loaded stationary ball
from contact with a fluid-wetted rotating cylindrical test ring operating under closely defined and controlled conditions.
3.1.2 wear scar—in the liquid fuels industry, average diameter of a worn and abraded area, measured in two specified directions,
produced on a test ball under defined conditions.
3.1.2.1 Discussion—
The wear scar generated by Test Method D5001 is often referred to as the BOCLE wear scar.
3.2 Abbreviations:
3.2.1 BOCLE—Ball On Cylinder Lubricity Evaluator
3.2.2 HRC—Rockwell Hardness “C” scale.
3.2.3 WSD—Wear Scar Diameter
4. Summary of Test Method
4.1 The fluid under test is placed in a test reservoir in which atmospheric air is maintained at 10 % relative humidity. A
non-rotating steel ball is held in a vertically mounted chuck and forced against the outside diameter of an axially mounted
cylindrical steel ring with an applied load. The test ring is rotated at a fixed speed while being partially immersed in the fluid
reservoir. This maintains the ring in a wet condition and continuously transports the test fluid to the ball/ring interface. The wear
scar generated on the test ball is a measure of the lubricating property of the fluid. For wear scar diameter (WSD) calibration and
standardization, see Section 10.
5. Significance and Use
5.1 Wear due to excessive friction resulting in shortened life of engine components such as fuel pumps and fuel controls has
sometimes been ascribed to lack of lubricity in an aviation fuel.
5.2 The relationship of test results to aviation fuel system component distress due to wear has been demonstrated for some
fuel/hardware combinations where boundary lubrication is a factor in the operation of the component.
5.3 The wear scar generated in the ball-on-cylinder lubricity evaluator (BOCLE) test is sensitive to contamination of the fluids
and test materials, the presence of oxygen and water in the atmosphere, and the temperature of the test. Lubricity measurements
are also sensitive to trace materials acquired during sampling and storage. Containers specified in Practice D4306 shall be used.
5.4 The BOCLE test method may not directly reflect operating conditions of engine hardware. For example, some fuels that
contain a high content of certain sulfur compounds can give anomalous test results.
6. Apparatus
6.1 For details of the Ball-On-Cylinder Lubricity Evaluator (BOCLE), apparatus required for each method see: Annex A1 for
the semi-automatic method, Annex A2 for the fully automatic method.
6.2 Microscope, capable of 100× magnification and suitable of measuring the wear scar on the ball to the nearest 0.01 mm.
6.2.1 Method of Measuring the Wear Scar—This may be either a Glass Slide Micrometer, with a scale ruled in 0.01 mm
7,8 7,9
divisions, or a digital micrometer and slide assembly, having a resolution of at least 0.01 mm.
6.3 Cleaning Bath—Ultrasonic seamless stainless steel tank with a capacity of 1.9 L and a cleaning power of 40W.
6.4 The test requirements are listed in Table 1.
7. Reagents and Materials
7.1 Test Ring, of SAE 8720 steel, having a Rockwell hardness “C” scale, (HRC) number of 58 to 62 and a surface finish of 0.56
7,10
to 0.71 μm root mean square. The dimensions are given in Fig. 1.
7.2 Test Balls, chrome alloy steel, made from AISI standard steel No. E-52100, with a diameter of 12.7 mm, Grade 5 to 10. The
balls are described in ISO 3290-1:2008. The HRC shall be 64 to 66, a closer limit than is found in the ISO requirement.

8. Sampling, Test Specimens, and Test Units
8.1 Cleaning of Apparatus and Test Components:
8.1.1 Test Rings, as Received:
8.1.1.1 The test rings shall be partially stripped of any protective coatings by manually rubbing them with rags or paper towels
saturated with isooctane.
8.1.1.2 Place partially cleaned rings in a clean 500 mL beaker. Transfer a sufficient volume of a 1 to 1 mixture of isooctane
(2,2,4-trimethyl pentane) and isopropyl alcohol to the beaker such that the test rings are completely covered.
8.1.1.3 Place beaker in ultrasonic cleaner and turn on for 15 min.
8.1.1.4 Remove test rings and repeat ultrasonic cleaning cycle of 8.1.1.3 with a clean beaker and fresh solvents.
8.1.1.5 Handle all clean test rings with clean forceps or disposable gloves. Remove test rings from beaker and rinse with
isooctane, dry, and rinse with acetone.
NOTE 1—Drying operations can be accomplished using a compressed air jet at 140 to 210 kPa pressure.
8.1.1.6 Dry and store in a desiccator.
8.1.2 Test Balls, as Received.
8.1.2.1 Place balls in 300 mL beaker. Transfer a sufficient volume of a 1 to 1 mixture of isooctane and isopropyl alcohol to the
beaker such that the test balls are completely covered by the cleaning solvent.
NOTE 2—Approximately a five-day supply can be processed at one time.
8.1.2.2 Place beaker in ultrasonic cleaner and turn on for 15 min.
8.1.2.3 Repeat the cleaning cycle of 8.1.2.2 with a clean beaker and fresh solvent.
8.1.2.4 Remove and rinse with isooctane, dry, and rinse with acetone.
8.1.2.5 Dry and store in a desiccator.
8.1.3 Reservoir, Reservoir Cover, Ball Chuck, Lock Ring, Mandrel Assembly (Method A, Semi Automatic Method) Test Ring
Assembly (Method B, Fully Automatic Method), and all other parts which come into direct contact with the test fuel (refer to the
appropriate annex).
8.1.3.1 Rinse with isooctane.
8.1.3.2 Clean in an ultrasonic cleaner with a 1:1 mixture of isooctane and isopropyl alcohol for 5 min.
8.1.3.3 Remove and rinse with isooctane, dry, and rinse with acetone.
8.1.3.4 Store in a desiccator until required.
8.1.4 Hardware:
8.1.4.1 The hardware and utensils, that is, any part that comes in contact with the test fluid shall be cleaned by washing
thoroughly with isooctane and wiped with a wiper.
8.1.4.2 Store parts in desiccator when not in use.
8.1.5 After Test:
8.1.5.1 Remove reservoir and test ring.
8.1.5.2 Disassemble components and clean in an ultrasonic cleaner using a 1 to 1 mixture of isooctane and isopropyl alcohol
for 5 min. Rinse with isooctane, dry, and rinse with acetone. Reassemble components.
8.1.5.3 Dry and store in a desiccator.
NOTE 3—When testing the same fluid, it is permissible to clean the reservoir by hand. The reservoir is rinsed with isooctane. Wipe with disposable
wiper to remove residual fuel related deposits and test debris. The reservoir is rinsed again with isooctane. Dry and final rinse with acetone, dry.
8.1.5.4 Store parts in desiccator when not in use.
8.1.5.5 Semi-Automatic (Method A) Only—Care shall be taken to ensure that the fuel aeration tube is rinsed and dried during
the cleaning procedure. Store parts in desiccator when not in use.
