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. Thank you for interesting in our services. We are a non-profit group that run this website to d23370 documents. 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.
NOTE 2—Mounting is facilitated by the use of air activated jaws.
See Note 1 for alternatives. Specific hazard statements are given in Section 7.
Wear gloves when handling mercury. Originally approved in Precision and Bias Small amounts of spilled mercury can vaporize sufficiently at room temperature to exceed the threshold limit values TLV of the vapor. Please help us to share our service with your friends. Line-type jaws will minimize slippage and breakage. 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.
We need your help! Significance and Use 5. Size px x x x x This standard has been approved asstm use by agencies of the Department of Defense. The last approved version of this historical standard is referenced on www.

A number in parentheses indicates the year of last reapproval. Users of this standard are expressly advised that determination of the validity of d237 such patent rights, and the risk of infringement of such rights, are entirely qstm own responsibility. The tensile properties of the free films are determined by means of a tensile testing apparatus.
Droplets of mercury can be picked up by using a small glass pipet connected to a suction flask with d22370 rubber hose. Current edition approved Dec. Tighten the grips evenly and firmly to the degree necessary to minimize slipping of the specimen during test. Its vapors are extremely hazardous.
Please fill this form, we will try to respond as soon as possible.
