4.2 Setting of Expected Flash Point
! Caution:
Ensure that an expected flash point is entered prior to every test run. If an expected flash point is not entered or the value entered is much greater than the actual flash point, the specimen catches a fire at the first application, and then the instrument is destroyed by fire.
The correct expected flash point entering is absolutely imperative. Enter/confirm the expected flash point before each test. The expected flash point (EXP FP) is displayed in three-digit figure in integer. When altering the expected flash point, press the Up-Down key to move the yellow cursor to EXP FP and press OK key. The
numeric figure change from
to 000. After the cursor is moved
to numeric figures of EXP FP, move the digit with Right-Left key and increase/decrease the value with the Up-Down keys. No numeric figures above 400 (760 in oF) can be set. Enter approximate expected flash point even if run a test with SPE method. If expected flash point is unknown, use SPE method and then set higher expected flash point. When selecting SPE method, ignition source application will be done just after start a test. So, a test will be done without worry. The other way, if entered expected flash point is too low, test will be canceled by safety over cut function. (Expected Flash Point+ 30oC(+ 60 oF)).

In case the temperature at which the first test flame application is made is above the fire point of the specimen, there is a danger: the specimen catches a fire to blaze up. So as to prevent such a danger in advance, for testing a sample of unknown flash point, use the SPE method. Be sure to arrange at least one proper person in your test room, lab, etc., when testing, to cope with possible accidents. ※ Test Sequence of ISO SPE, ASTM SPE in Fahrenheit Entered EXP.FP → 203 oF Start Specimen Temp → 70 oF First Application Temp → 73 oF (Application Interval 5 oF) Over Cut Temp → 263 oF (Entered EXP.FP + 60 oF)

4.6 Preparation of Test Cup and sample (1)
Wash the test cup with the cleaning solvent to remove any test specimen or traces of gum or residue remaining from a previous test. When the upper side of cup’s flange is covered with carbon deposit, the flash detector cannot operate normally. Also when conductive material adheres to the insulator of electrode ring (outer ring), bad insulation can cause mis-detection of flash. Therefore, keep the parts cleanly.
(2) When testing samples of very viscous materials and containing dissolved or free water, follow Sampling section of ISO 2592/ASTM D92. (3) Fill the test cup with the test specimen to the filling mark inside of the test cup. (4) Push up the arm handle and place the test cup on the center of the heater. (5) Lower the arm gently until stopper is touching the flange of the cup.

Note(4): Expected Flash Point can be changed even during the test. After changing expected flash point in accordance with Section 4.2, re-press the start key. Also in this case, the newly set expected flash point appears in the center of the display for 5 seconds. Note(5) Heater output can be confirmed by Heater Output Indicator. Lighting: 100% full power Extinction: 0% (no heat) Blink: interlevel In most cases, heater output varies and then this indicator blinks. Test flame is ignited by dual pilots automatically. The time until auto ignition will be seconds (continuous run) to minutes (first run)(6). Do not leave the instrument until ignition is confirmed. Adjust the test flame to 4mm in diameter (the flame size comparison bead size) by needle valve. Note(6): The first run after the gas piping (installation or transfer of the instrument), there is full of air in the gas hose. Lift the windscreen and then open the needle valve for test flame fully to get out air from the hose. Be careful that the big flame comes out from the nozzle when ignites. After this, turn the needle valve clockwise to adjust the flame size. Besides, flame grows big slowly because the portion of the gas increases with the same flow rate till air can be removed completely. Please take care valve operation diligently for the first run. The test proceeds automatically hereafter.

5.2 Test Sequence After the test starts, the specimen temperature rises at a rate of 14 to 17 oC /min(25 to 30 oF /min). When the temperature reaches 56 oC (100 oF) below the expected flash point, the heating rate is decreased so that the rate of temperature increase during the last 28 oC (50 oF) before the expected flash point is 5 to 6 oC(9 to 11 oF). When the temperature of the test specimen is 28 oC(50 oF) below the expected flash point, the test flame begins to apply. After that, the application operation is repeated at each 2 oC(5 oF). Note: heating rate might be unstable in particular kind of sample like asphalt.
5.3 Flash Detection When a flash is detected, the Flash Point is displayed on the screen as Fig. 17, and then starts blink(7). At the same time buzzer beeps intermittently for 8 seconds. Furthermore, the solenoid valve for gas is closed, the test flame goes out and dual pilot goes off, and the stove section starts cooling. (background of temperature display turns green). When “ASTM Fire” or “ISO Fire” Method is selected, aco-8 suspends a test 1 minute. During this suspend, push start key again to continue fire point test, otherwise aco-8 terminates a test and then starts cooling. Please do not leave the aco-8 until fire point is detected. Fire point test is dangerous. Cleveland Open Cup EXP FP Sample ID

The Flash Point (8) blinking on the screen is corrected by barometric pressure and rounded, not observed. The test result is automatically stored in the memory. To view the stored data, refer to chapter 0. Data Storage. Note(7)(8):The calculation of the flash point is done by following procedure. (1) Calculate the corrected flash point, Tc, using the following equation TC = To + 0.025（1013 - P） where To: the observed flash point, in oC P ：the barometric pressure (hPa) measured by built-in barometric pressure sensor (2) Round Tc to the nearest 1.0 oC(ASTM) or 2.0 oC (ISO) or 0.1 oC(ISO CRM)
（2.0 oF）
（2.0 oF）
（2.0 oF）
For example, the flash is detected at 222 oC. And then measured barometric pressure is 970hPa, the corrected flash point will be “223.075” by above equation, then to be “223” by rounded to the nearest 1.0 oC(ASTM), then to be “224” by rounded to the nearest 2.0 oC(ISO). When measured barometric pressure is between 974 and 1052hPa, observed flash point and the flash point will be the same value.

In this case, screen shows “INVALID: flashed on 1st appl” under the flash point display as Fig. 18. Do a test again with fresh sample and lower EXP FP.

< If a flash has not been detected when the safety cut temperature is reached > This instrument has a function to prevent overheat called “safety cut temperature”. The safety cut temperature is set at EXP FP+30 oC (+60 oF)or upper limit of the test method. If a flash has not been detected when the safety cut temperature is reached, terminate the test forcibly. (Solenoid valve for gas is closed, the test flame goes out and dual pilot goes off, and the heater

5.4 Fire Point Detection When “ASTM Fire” or “ISO Fire” Method is selected, and then operator push start key again after detectiong flash point, aco-8 continue a test until fire point. ※Please note that there is no automatic transition from the flash point test to the fire point test. Once flash point is detected the buzzer sounds intermittently for 1 min, please push start key again within 1 min to continue a fire point test. When aco-8 detects continuous specimen burning for 5 seconds, test is terminated, fire containment lid activates to extinguish a fire, and then display shows fire point and flash point alternately. In the fire method, aco-8 does not move to cooling cycle automatically for safety reason. Operator has to confirm the fire is extinguished completely, and then reset fire containment lid to the original position, then move the cursor to COOL by Up-Down key or Right-Left key, and then press the OK key to start cooling.

5.5 Flash Point Detection By manual detection First of all the flash point detection principle of aco-8 is considered as a flash when there is conduction between two large and small flash detection rings (usually insulated). This means that if there is conduction between the rings other than the flame at the time of flash point, it will be detected. Therefore, If the sample expands excessively due to heating and touches the rings, or if bubble is generated from the sample and touches the rings, false detection may occur. In such cases, please use the following manual detection mode. When “ASTM Manual” or “ISO Manual” or “ASTM Skim+Man” or “ISO Skim+Man” Method is selected, aco-8 ignores the first detection even if detected by foam or sample expansion, and then operator push start key again after ignoring the first detection, aco-8 continue a test until flash point detection.However, even if the initial sample expansion or bubble contact to rings can be detected automatically, there is no way to determine which is the true flash point, so the flash point detection is a visual check by operatiors. Once the first detection by sample expansion or bubble is detected the buzzer sounds intermittently for 1 min, please push start key again within 1 min to continue a test. After that, automatic detection is not possible, so flash point detection is a manual operation by visual check. Do not leave until you see the flash point or test end. After visually checking the flash point please press the START key immediately. Pressing the START key is regarded as a flash point detection and the flash point result is displayed. In these method, aco-8 does not move to cooling cycle automatically for safety reason. Operators move the cursor to COOL by Up-Down key or Right-Left key, and then press the OK key to start cooling.

5.6 Test End
! Warning:
Never touch the test cup with bare hands after the test end. The sample cup may still hot and the operator gets burned. Use gloves and hold the test cup handle for operator’s safety.
! Warning: Never discard hot sample to a waste tank. Sample in the
waste tank may blow up. ! Warning:
Never discard hot sample to a waste tank. Sample in the waste tank may blow up.
