14 Test Method: ASTM D943, D2274, D2893, D4310 Digital indicating temperature control maintains ±0.1 C stability Agitated liquid bath with 4 to 60 test positions Overall dimension 22 x 18 x 23 (55x 45x 58 cm) Temperature range of 40 to 120 C Supplied with eight flow meters Low level safety cut off switch The liquid Oxidation Bath meet the requirements of ASTM D943, D2893*, D4310, D6158, AOCS12-57* test methods (* modified version for these methods is available). Each test position has one float-in-tube tube flowmeter positioned in front. The oxygen flow rate is maintained at 3 ± 0.1 L/hr with a micro precision valve. An oxygen pressure regulator is optionally available. Temperature control is provided by a digital display PID controller providing stability of ± 0.2º C or better. In the event of primary controller failure the bath is protected by a secondary high limit controller. Useful temperature range is from 40º C up to 120º C. The 30 or 60 positions are arranged in two back to back rows (15 or 30 positions each) suitable for those laboratories with an isle bench. Water flow to each condenser is controlled by a valve mounted on the back panel. This is available only if the condenser water flows directly to a waste drain. If a recirculating chiller is to be used only one flow valve is provided for each group of 12 condensers which must be arranged in series. 10

15 Test Method: Fully Conforms to the Manual ASTM D2500 No Cryostat required No Hazardous alcohol required Compact design Fully Automated Self Contained The Automated Cloud Point Analyzer fully meets the requirements of ASTM D2500. The dimensions of the glassware, the metal test jacket, position of probes, cooling profile, and other parameters are identical as specified by the manual method. The analyzer software confirms cloud point when the fiber optics detects reduction of the pulsing green light reflected from the bottom of the silvered test tube. Green light of a specific wave length has been found to most accurately simulate the human eye sensitivity for the cloud point. The chillers for cooling the automated analyzers use the concept of direct refrigeration. The test cup (metal jacket) for cloud point, pour point, or CFPP is directly cooled by the refrigerant, thus replacing the middle step of first cooling the flammable alcohol and then pumping the cold alcohol to the test jacket. Offers the additional advantage of rapid cool down to test temperature within minutes versus hours with bulky floor model cryostat models. The automated analyzer is mounted on the same cabinet as the refrigeration system, thus saving valuable laboratory space. DR4 series coolers are available in 1 or 2 test positions with lowest temperature of either -34 or -70 C. 11

24 Test Method: ASTM D6079; ISO Features and Benefits Capable of engaging a steel ball loaded against a stationary plate with an applied load and oscillating at a fixed frequency and stroke length while the contact interface is fully immersed in a fluid reservoir. A 2-mL test specimen of fuel is placed in the test reservoir and maintained at 25 or 60 C. When the temperature has stabilized, a vibrator arm holding a non-rotating steel ball and loaded with a 200-g mass is lowered until it contacts a test disk completely submerged in the fuel. The ball is caused to rub against the disk with a 1-mm stroke at a frequency of 50 Hz for 75 min. The ball is removed from the vibrator arm and cleaned. The dimensions of the major and minor axes of the wear scar are measured under magnification and recorded. High-Frequency Reciprocating Rig (HFRR) The two-station Fuel Lubricity Wear Test Machine incorporates two test positions with heater pads and mounting arrangements for fuel lubricity test specimens. Load is applied manually by means of dead weights directly to the fixed ball specimen carrier by means of a loading yoke. Machine controls are limited to speed control of the drive motor to give the required frequency, temperature control of the specimen bath and test duration. Test data is limited to post test wear scar measurement only and no facilities are provided for friction force measurement. The electro-mechanical drive is used to achieve a wide range of frequencies, and the 1 mm stroke is generated with a cam. This ensures that the amplitude remains constant as friction forces vary in the contact. The ball specimen is mounted in a holder connected to the horizontal oscillating shaft. The shaft is double ended and two tests can be run at the same time. The holder is hinged to ensure that the line of action of the oscillator remains in the horizontal plane of contact. This also means that loads can be applied directly to the contact without loading the oscillator shaft. A simple yoke locates on the oscillating shaft and load is applied by calibrated weights. 21

25 The plate specimen is located in a bath that both seals and clamps the specimen. Beneath the bath is a block that is heated by an electrical resistance element and the temperature is controlled by a thermocouple closely located beside the specimen. Each heater block is mounted on a stiff fabricated support. A clear acrylic cover is provided to house the test heads. Operation of the machine is straightforward. The machine is equipped with two digital programmable controllers for temperature. Temperature setpoint can therefore be set independently for each station. In addition, there is a digital programmable frequency controller and test timer. The controllers are pre-set when the machine leaves the factory to the operating conditions required of the test methods. Once enabled, the machine heats each of the baths to a set point of 60 C. Once this temperature is reached the motor is switched on automatically to run at 50Hz. The test timer is preset for the duration of 75 minutes, which commences once the motor starts. At the end of the test the machine automatically switches off.

26 Test Method: EN-14112, ASTM D6751, ISO 6886 Multiple models available to fit any budget Conforms to EN test method for B100 biodiesel Measures oxidation stability of FAME (fatty acid methyl esters) Conforms to ASTM D6751 specifications Automated operation Windows PC Data Acquisition Software Operating temperature from 40 to 150 C Temperature stability of ±0.1 C The oxidation stability baths conform to the requirements of EN test method, incorporated in ASTM D6751 specifications for B100 fatty acid methyl esters (FAME) for biodiesel blending. They employ an aluminum block configured to fit the specified test tube holding 3.0 gm of FAME (fatty acid methyl esters). When the sample reaches test temperature of 110 C filtered, dry air is sparged at 10 ± 1L/hr. to each test specimen. The volatiles generated (organic acids) from this oxidation process are collected in a receiver of distilled or deionized water. The increase of acidity in the receiver is measured with time with an integral conductivity measuring device. The oxidation induction period is automatically calculated based on the break in the rate of increase (second derivative) of conductivity in the receiver. Each positions receiver has cap with an integral conductivity probe reporting data to the PC. 20
