Electromechanical Universal Testing Machine 100kN Small Clear Specimens of Timber ASTM D143 ETM105D

Electromechanical Universal Testing Machine 100kN Small Clear Specimens of Timber ASTM D143 ETM105D


Function

The ETM type D Series addresses the needs of standardized and routine testing, providing the user high quality at the most affordable price. The dual column testing systems with rugged structure are suited for tension and/or compression applications with load range requirement. They are typically used for quality control and production testing.


Applications

Tension, bending, compression, tearing, shearing for Metals, building components, large fasteners, composites, wood products


Standards: ASTM D143

Standard Test Methods for Small Clear Specimens of Timber


Scope
These methods cover the determination of various strength and related properties of wood by testing small clear specimens.
These methods represent procedures for evaluating the different mechanical and physical properties, controlling factors such as specimen size, moisture content, temperature, and rate of loading.
Sampling and collection of material is discussed in Practice D 5536. Sample data, computation sheets, and cards have been incorporated, which were of assistance to the investigator in systematizing records.
The values stated in inch-pound units are to be regarded as the standard. The SI values are given in parentheses and are provided for information only. When a weight is prescribed, the basic inch-pound unit of weight (lbf) and the basic SI unit of mass (Kg) are cited.


This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Summary of Methods
The mechanical tests are static bending, compression parallel to grain, impact bending toughness, compression perpendicular to grain, hardness, shear parallel to grain (Note 1), cleavage, tension parallel to grain, tension-perpendicularto-grain, and nail-withdrawal tests. These tests may be made on both green and air-dry material as specified in these methods. In addition, methods for evaluating such physical properties as
specific gravity, shrinkage in volume, radial shrinkage, and tangential shrinkage are presented.


Static Bending
Size of Specimens—The static bending tests shall be made on 2 by 2 by 30 in. (50 by 50 by 760 mm) primary method specimens or 1 by 1 by 16 in. (25 by 25 by 410 mm) secondary method specimens. The actual height and width at the center and the length shall be measured.


Loading Span and Supports—Use center loading and a span length of 28 in. (710 mm) for the primary method and 14 in. (360 mm) for the secondary method. These spans were established in order to maintain a minimum span-to-depth ratio of 14. Both supporting knife edges shall be provided with bearing plates and rollers of such thickness that the distance from the point of support to the central plane is not greater than
the depth of the specimen (Fig. 3). The knife edges shall be adjustable laterally to permit adjustment for slight twist in the specimen.


Bearing Block—Abearing block of the form and size shall be used for applying the load for primary method specimens. A block having a radius of 11⁄2 in. (38 mm) for a chord length of not less than 2 in. (50 mm) shall be used for secondary method specimens.


Placement of Growth Rings—The specimen shall be placed so that the load will be applied through the bearing block to the tangential surface nearest the pith.


Speed of Testing—The load shall be applied continuously throughout the test at a rate of motion of the movable crosshead of 0.10 in. (2.5 mm)/min (see 22.3), for primary method specimens, and at a rate of 0.05 in. (1.3 mm)/min for secondary method specimens.


Impact Bending
Size of Specimens—The impact bending tests shall be made on 2 by 2 by 30 in. (50 by 50 by 760 mm) specimens. The actual height and width at the center and the length shall be measured (see 22.2).
Loading and Span—Use center loading and a span length of 28 in. (710 mm).
Bearing Block—A metal tup of curvature corresponding to the bearing block shown in Fig. 4 shall be used in applying the load.
Placement of Growth Rings—The specimen shall be placed so that the load will be applied through the bearing block to the tangential surface nearest the pith.
Procedure—Make the tests by increment drops in a Hatt-Turner or similar impact machine (see Fig. 11). The first drop shall be 1 in. (25 mm), after which increase the drops by 1 in. increments until a height of 10 in. (250 mm) is reached.
Then use a 2 in. (50 mm) increment until complete failure
occurs or a 6 in. (150 mm) deflection is reached.
