ASTM D 3043 – 00 Structural Panels in Flexure

The choice of method will be dictated by the purpose of the test, type of material, and astj availability. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Take deflection readings to the nearest 0. However, it may be used to determine d30443 effects of finger joints, veneer joints and gaps, and other features which can be placed entirely between the load points and whose effects can be projected readily to full panel width. Width shall be 1 in.

State clearly the method employed in the report. Please help us to share our service with your friends. D — 00e1 Standard Test Methods for Structural Panels in Flexure1 This standard is issued under the fixed designation D ; the number immediately following r3043 designation indicates the year of original adoption or, in the case of revision, the year of last revision.

Take deflections by the methods indicated in Fig. A spacing of at least 24 and 12 times specimen thickness is recommended for specimens with the principal direction parallel and perpendicular to span respectively. 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.

To eliminate plate action when wider specimens are tested, the specimen width shall not exceed one third of the span length and precaution shall be taken to ensure uniform bearing across the entire width of the specimen at the load and reaction points.

The frames shall be free to move toward or away from each other while under load to preclude application of direct tension or compression loads at large panel deformations.

Four methods of tests are included:. 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.

An electronic transducer could be substituted for the dial gage for direct recording if system accuracy is adequate. Specimen size and span above certain minimums are quite asm.

Total deflection, and modulus of elasticity computed from it, include a relatively constant component attributable to shear deformation.

The rate of load application shall be such that the maximum fiber strain rate is equal to 0. Referenced Documents purchase separately Astn documents listed below are referenced within the subject standard but are not provided as part of the standard.

It is preferred when equipment is available. These properties are of primary importance in most structural uses of panels whether in construction for floors, wall sheathing, roof decking, concrete form, or various space plane structures; packaging and materials handling for containers, crates, or pallets; or structural components such as stress-skin panels. Structural panels in use include plywood, waferboard, oriented strand board, and composites of veneer and of wood-based layers.

Moments applied aztm fail specimens tested by Method A, B or D in which large deflections occur can be asrm larger than nominal. Similar requirements apply to the load axis. Carefully controlled investigations may require specification or construction of more precise equipment. These errors are not present in Method C. We need your help! If individual gage readings are taken, at least 12 and preferably 15 or more load and deflection readings shall be taken below approximate proportional limit or for determining adtm stiffness.

Construction is shown in detail in Fig.

Historical Version s – view previous versions of standard. Deflection of mid span relative to two points just inside the load points is measured with a dial gage or transducer thus giving deformation due to pure bending and unaffected by shear deformation. Measurements shall be to the nearest 0. Calculate the rate of motion of the movable head as follows: Also like Method A, this method uses small specimens in a center-point simple span test configuration.
