F sstm 04 Standard Test Methods for Fluid Resistance of Gasket Materials1 This standard is issued under the fixed designation F ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
A number in parentheses indicates the year asym last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense. These test methods are not applicable to the testing of vulcanized rubber, a procedure that is described in Test Method D Asrm is designed for testing specimens cut from gasketing materials or from finished articles of commerce. The inch-pound units in parentheses are for information only. 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.
Summary of Test Methods 3.
ASTM F – 04 Standard Test Methods for Fluid Resistance of Gasket Materials
After immersing the specimens in the various test fluids, the effect on physical properties is expressed as change in tensile strength, compressibility in softened condition, flexibility, volume change, and thickness and weight changes from the original condition.
Significance and Use 4. The results of these test methods are not intended to give any direct correlation with service conditions in view of the wide variations in temperature and special uses encountered in gasket applications.
The specific test fluids and test conditions outlined were selected as typical for purposes of comparing different materials and can be used as a routine test when agreed upon between the purchaser and the manufacturer.
Current edition approved April 1, Originally approved in Last previous edition approved in as F — Dead weight loads are listed in Table 1. Temperature of Test Measurement 7. These test methods are applicable to ethylene glycol, propylene glycol, commercial coolants and blends with water thereof see Note 1water, and other commercial oils and fuels.
The producer must be aware that different coolant mixtures may yield different results. Refer to Test Method D for further information regarding immersion test fluids.
ASTM F 146 – 04
BoxTrenton, NJ The user should be aware that results may asgm. NOTE 1—Coolant mixtures are typically tested under boiling reflux conditions.
Graduate the dial in 0. The anvil shall have a diameter not less than that of the presser foot, which has a diameter of 6.
ASTM F146 – 12
Take a sufficient number of readings, depending on the size of the specimen, to provide a reliable average value. Measure the weight atm the test specimen to the nearest 1 mg 0. Pour enough fresh fluid into the tube to completely cover the specimens and ensure that they are immersed. Insert the aluminum-foil covered stoppers into the test tubes before placing them in awtm supporting rack within the oven. Then withdraw the specimens from the cooled-down test fluid and immediately blot the samples with sheets of blotting paper to remove excess liquid from the surfaces.
Exercise care when removing the excess fluid so that no squeezing action occurs on the sample. Aztm enough fresh test fluid over the specimens to ensure that qstm specimens are wetted and covered by the fluid. Use enough fluid to provide a minimum of 10 mL for each specimen in the container.
If such information is not available, then the material should be tested by itself in fresh fluid to determine compatibility with said fluid.
The change in thickness of the specimens is to be calculated as astj expression of percentage change from the original thickness.
NOTE 2—Great care must be taken to record the swollen thickness when the needle slows to a different rate which reflects indentation into the softened specimen. For materials having less than specific gravity 1.
This gives the final volume, V2. Change the distilled water used in the test frequently. Use the same sinker throughout. The change in weight of the f14 is to be calculated as an expression of percentage change on the original weight. It is understood that the results will be reported per D along with the specific immersion conditions used prior to said adhesion test.
Other physical property tests described in this standard are not applicable for these materials. Type 1 Class 2—A BA material, containing a normally lower swelling polymer.
Precision and Bias 7 There were six Type 1,7, three Type 3, and one Type 5 material evaluated for immersion weight change and thickness change in IRM oil.
