D — 98 Reapproved Standard Test Method for Tensile Properties of Organic Coatings1 This standard is issued under the fixed designation D; 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 of last reapproval. This standard has been approved for use by agencies of the Department of Defense. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
It is the zstm of asym user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory ast, prior to use.
Specific hazard statements are given in Section 7. Summary of Test Method 4. The tensile properties of the free films are determined by means of a tensile testing apparatus.
Significance and Use 5. Consequently, where precise comparative results are desired, these factors must be carefully controlled. Current edition approved Dec. Originally approved in The last approved version of this historical standard is referenced on www.
Procedure to gand equipped with an indicating device such as an electronic constant speed chart recorder, a digital device that displays numerical values, or a printer that records the numerical values.
These specimens should not exhibit any nicks or flaws. Measure the thickness of each specimen to Place the test specimen in the grips of the testing machine, taking care to align the long axis of the specimen with an imaginary line joining the points of attachment of the grips to the machine.
Tighten the grips evenly and firmly to the degree necessary to minimize slipping d230 the specimen during test. Its vapors are extremely hazardous. Small amounts of spilled mercury can vaporize sufficiently ast, room temperature to exceed the threshold limit values TLV of the vapor. Use with adequate ventilation in a hood and clean up spills immediately. Wear gloves when handling mercury. Droplets of mercury can be picked up by using a small glass pipet connected to a suction flask with a rubber hose.
NOTE 2—Mounting is facilitated by the use of air atsm jaws. Line-type jaws will minimize slippage and breakage. The application of pressure-sensitive cloth astn the ends of the film can improve jaw grip. Set the crosshead speed of the axtm tester to provide this rate for the gage length chosen.
NOTE 3—A rate of elongation should be selected that is optimum for testing the types of materials to be evaluated. Refer to Test Methods D for relation of elongation rate to elongation at break. The length shall be at least 2 in. Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend.
However, it is no longer available. See Note 1 for alternatives.
Precision and Bias Choose asmt of the following procedures for discarding spurious values and calculate the mean of the remaining results: This is done on the basis that the expected errors nicks or flaws in the specimen, breaks within the jaw, slippage in the jaw, etc. Use the aastm for outliers given in Practice D — Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
