Set the crosshead speed of the tensile tester to provide this rate for the gage length chosen. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Tighten the grips evenly and firmly to the degree necessary to minimize slipping of the specimen during test.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 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.
Specific hazard statements are given in Section 7.
Refer to Test Methods D for relation of elongation rate to elongation at break. However, it is no longer available. Significance and Use 5.
This standard has been approved for use by agencies of the Department of Defense. These specimens should not exhibit any nicks or flaws. 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.

Use d237 test for outliers given in Practice D — 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. Small amounts of spilled mercury can vaporize sufficiently at room temperature to exceed the threshold limit values TLV of the vapor. Measure the thickness of each specimen to A number in parentheses indicates the year of last reapproval.
NOTE 2—Mounting is facilitated by the use of air activated jaws. Precision and Bias Consequently, where precise comparative results are desired, these factors must be carefully controlled. Line-type jaws will minimize slippage and breakage. The tensile properties of the free films axtm determined by means of a tensile testing apparatus. Please help us to share our service with your friends. Originally approved in 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.
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. See Note 1 for alternatives.
We need your help! Wear gloves when handling mercury. It is the responsibility of the user of this s2370 to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Use with adequate ventilation in a hood and clean up spills immediately.
The application of pressure-sensitive cloth to the ends of the film can improve jaw grip. Summary of Test Method 4.
