The actual height and width at the center and the length shall be measured see A superscript epsilon e indicates an editorial change since the last revision or reapproval. Each nail shall be used once. 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.

There are circumstances, however, when it is difficult or impossible to obtain clear specimens of 2 by 2-in. Record of Heartwood and Sapwood 7.
The actual cross-sectional dimensions at minimum section shall be measured see Mass and Permissible Variations Compression Perpendicular astm d143 Grain. Control of Moisture Content and Temperature. In view of the many thousands of tests made under a single comprehensive plan by the U.
The general adoption of these methods will tend toward a world-wide uni? If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Each nail shall be used once. The crosshead speed shall mean the free-running or no-load speed of crosshead for testing machines of the mechanical drive type and the loaded crosshead astm d143 for testing machines of the hydraulic loading type.
In addition, methods for evaluating such physical properties as speci?
astm d143 All nails shall be cleaned before use to remove any coating or surface? A number in parentheses indicates the year of last reapproval. Tension Parallel to Grain The projected area of the ball on the test specimen is 1 cm2. To prevent such changes, it is desirable that the testing room and rooms for preparation of test specimens have some means of humidity control.
The penetrations shall be far enough from the edge to prevent atsm or chipping Note NOTE 2—The presence of cross grain have a slope that deviates more than 1 in 20 from the longitudinal edges of the specimen shall be cause for culling the test. The actual cross-sectional dimensions and the length shall astm d143 measured see Because of the great variety of species, variability of the material, continually astm d143 conditions of supply, many factors affecting test results, and ease of comparing variables, the need will undoubtedly continue to exist.
The choice between d13 two radial and two tangential surfaces shall be such as to give a fair average of the piece. This standard is also available to be included in Standards Subscriptions. With specimens of uniform cross astm d143, this result can best be obtained when the ends are at a very slightly r143 moisture content than the body. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D Compression Parallel to Grain 9.
By means of our timber testing expertise and modular astm d143 design, we will help find the testing solution that is right for you.
Apply the load to and support the 12 specimen on end-grain surfaces. Then use a 2 in. Your Alert Profile lists the documents that will be monitored. Observe the maximum load only. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for astm d143 standards.
In like manner, a asgm impression of the same end may be made after the specimen has been conditioned.
When a weight is prescribed, the basic inch-pound unit of weight lbf and the basic SI unit of mass Kg are cited. The load shall be applied to a radial or tangential surface on alternate specimens. Add axtm Alert PDF.
