A number in parentheses indicates the year of last reapproval. In the preparation of these methods for testing small clear specimens, consideration was given both to the desirability of adopting methods that would yield results comparable to those ast available and to the possibility of embodying such improvements as experience has shown desirable.

This standard has been approved for use by agencies of the Department of Defense. The choice between the two radial and between the two tangential surfaces shall be such as to give a fair average of the piece.

Record of Heartwood and Sapwood 7. We'll only use this information to connect you to an application expert and it won't be shared with anyone else. If difficulty is experienced with high-density woods in pulling the nails without breaking the heads, a sevenpenny cement-coated sinker nail with coating removed by use of a suitable solvent, may be used.

Radial and Tangential Shrinkage.

We are confident that we have what you are looking for. The curves shall be continued to a 6 in. Shear Parallel to Grain These specimens shall be photographed in cross section and on the radial and tangential surfaces.

The toughness shall then be calculated as follows: Where adtm application, measurement, or recording of load and de? All nails shall be cleaned before use to remove any coating or surface?

The actual cross-sectional dimensions and length shall be measured see In general, nails should not be driven closer than 3? These tests may be made on both green and air-dry material as speci?

The two nails on a radial or tangential face should not be driven in line with each other or less satm 2 in. In all cases where the failure at the base of the specimen extends back onto the supporting surface, the test shall be culled.

However, take care to ensure that vertical displacements which may occur at the reactions are accounted for.

The aastm should then be weighed and the volume determined by the immersion method.

Need help or have a question? These spans were established in order to maintain a minimum span-to-depth ratio of The actual cross-sectional dimensions at minimum section shall be measured see This size of specimen has been extensively used for the 1d43 of various mechanical and physical properties of different species of wood, and a large number of data based on this primary method have been obtained and published.

Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The actual cross-sectional dimensions and the length shall be measured see Satisfies numerous shear testing standards Used to test the shear strength of an adhesive interface between two blocks Top loading surface can rotate to accommodate non-parallel specimen surfaces.

After the proportional limit is reached, less re? Validating the specifications, value and safety of your raw materials, products and assets.
