  • ASTM D56 for flash point by Tag closed cup tester 13. Report13.1 Correction for barometric pressure. Observe and record the ambient barometric pressure at the time and place of the test. When the pressure differs from 101.3 kPa (760 mm Hg), correct the flash point as follows:Corrected flash point = C + 0.25 (101.3 - p)Corrected flash point = F + 0.06 ...
  • ASTM D56 for flash point by Tag closed cup tester 12. Procedure (Automated)12.1 Adjust the external cooling system, if required, to a temperature necessary to cool the heating area 10°C below the expected flash point.12.2 Place the test cup in position in the instrument.12.3 Enter the Expected Flash Point; this will allow the heating area to be cooled ...
  • ASTM D56 for flash point by Tag closed cup tester 10. Apparatus (Automated Instrument)10.1 An automated flash point instrument is used that is capable of performing the test in accordance with Section 9. The apparatus can use a gas test flame or electric ignitor. The dimensions for the test cup and test cover are shown in Fig. A1.1 and Fig. A1.2.10.2 ...
  • ASTM D56 for flash point by Tag closed cup tester 9. Procedure (Manual)9.1 Using a graduated cylinder and taking care to avoid wetting the cup above the final liquid level, measure 50 more or less 0.5 mL of the sample into the cup, both the sample and graduated cylinder being precooled, when necessary, so that the specimen temperature at the time of ...
  • ASTM D56 for flash point by Tag closed cup tester 7. Sampling7.1 Erroneously high flash points will be obtained when precautions are not taken to avoid the loss of volatile material. Containers should not be opened unnecessarily to prevent loss of volatile material and possible introduction of moisture. Transfers should not be made unless the sample ...
  • ASTM D56 for flash point by Tag closed cup tester 4. Summary of Test Method4.1 The specimen is placed in the cup of the tester and, with the lid closed, heated at a slow constant rate. An ignition source is directed into the cup at regular intervals. The flash point is taken as the lowest temperature at which application of the ignition source causes ...
  • ASTM D56 for flash point by Tag closed cup tester 3. Terminology3.1 Definitions3.1.1 Flash point - the lowest temperature corrected to a pressure of 101.3 kPa (760 mm Hg) at which application of an ignition source causes the vapors of a specimen of the sample to ignite under specified conditions of test.3.1.1.1 Discussion - The specimen is deemed to ...
  • ASTM D56 for flash point by Tag closed cup tester 1. Scope1.1 This test method covers the determination of the flash point, by tag manual and automated closed testers, of liquids with a viscosity below 5.5 mm2/s (cSt) at 40°C (104°F), or below 9.5 mm2/s (cSt) at 25°C (77°F), and a flash point below 93°C (200°F).1.1.1 For the closed-cup flash point ...
  • ASTM D56 for flash point by Tag closed cup tester Introduction To ensure an acceptable precision, this dynamic flash point test method employs a prescribed rate of temperature rise for the material under test. The rate of heating may not in all cases give the precision quoted in the test method because of the low thermal conductivity of certain materials. ...
