4.1 This test method may be used as a substitute for, or in conjunction with, coring to determine the thickness of slabs, pavements, decks, walls, or other plate structures. There is a certain level of systematic error in the calculated thickness due to the discrete nature of the digital records that are used. The absolute systematic error depends on the plate thickness, the sampling interval, and the sampling period.4.2 Because the wave speed can vary from point-to-point in the structure due to differences in concrete age or batch-to-batch variability, the wave speed is measured (Procedure A) at each point where a thickness determination (Procedure B) is required.4.3 This test method is a pplicable to plate-like structures with lateral dimensions at least six times the thickness. These minimum lateral dimensions are necessary to prevent other modes3 of vibration from interfering with the identification of the thickness mode frequency in the amplitude spectrum. As explained in Note 12, the minimum lateral dimensions and acceptable sampling period are related.4.4 The maximum and minimum thickness that can be measured is limited by the details of the testing apparatus (transducer response characteristics and the specific impactor). The limits shall be specified by manufacturer of the apparatus, and the apparatus shall not be used beyond these limits. If test equipment is assembled by the user, thickness limitations shall be established and documented.4.5 This test method is not applicable to plate structures with overlays, such as a concrete bridge deck with an asphalt or portland cement concrete overlay. The method is based on the assumption that the concrete plate has the same P-wave speed throughout its depth.4.6 Procedure A is performed on concrete that is air dry as high surface moisture content may affect the results.4.7 Procedure B is applicable to a concrete plate resting on a subgrade of soil, gravel, permeable asphalt concrete, or lean portland cement concrete provided there is sufficient difference in acoustic impedance3 between the concrete and subgrade or there are enough air voids at the interface to produce measurable reflections. If these conditions are not satisfied, the waveform will be of low amplitude and the amplitude spectrum will not include a dominant peak at the thickness frequency. If the interface between the concrete and subgrade is rough, the amplitude spectrum will have a rounded peak instead of a sharp peak associated with a flat surface.4.8 The procedures described are not influenced by traffic noise or low frequency structural vibrations set up by normal movement of traffic across a structure.4.9 The procedures are not applicable in the presence of mechanical noise created by equipment impacting (jack hammers, sounding with a hammer, mechanical sweepers, and so forth) on the structure.4.10 Procedure A is not applicable in the presence of high amplitude electrical noise, such as may produced by a generator or some other source, that is transmitted to the data-acquisition system.1.1 This test method covers procedures for determining the thickness of concrete slabs, pavements, bridge decks, walls, or other plate-like structures using the impact-echo method.1.2 The following two procedures are covered in this test method:1.2.1 Procedure A: P-Wave Speed Measurement—This procedure measures the time it takes for the P-wave generated by a short-duration, point impact to travel between two transducers positioned a known distance apart along the surface of a structure. The P-wave speed is calculated by dividing the distance between the two transducers by the travel time.1.2.2 Procedure B: Impact-Echo Test—This procedure measures the frequency at which the P-wave generated by a short-duration, point impact is reflected between the parallel (opposite) surfaces of a plate. The thickness is calculated from this measured frequency and the P-wave speed obtained from Procedure A.1.2.3 Unless specified otherwise, both Procedure A and Procedure B must be performed at each point where a thickness determination is made.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.4 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 Due to the variety of small bone fractures, plates used for the fixation of these fractures come in a variety of shapes and configurations. Table 1 categorizes the plate types for each anatomical area. Flat plates are the simplest; see Fig. 2 for an example of a basic flat plate. Many other plates have features to accommodate specific anatomies, such as condylar, complex (such as cuneiform), pre-contoured (such as metatarsophalangeal joint (MPJ)), step, orbital, orthognathic step, and wedge plates. Other plates, such as mesh-based and burr hole plates, are generally flat but are designed to be used in specific anatomical regions, so their designs are not the same as conventional straight plates. If test data is used from one type of plate for justification of the mechanical properties of another type of plate, this justification shall be described in the final report.4.2 Most of the testing described herein is focused on a “functional unit,” which can be described as a single-line fracture being spanned by a plate with one screw hole on each side of the fracture. This configuration allows for the simplest determination of worst-case size if the strut geometry is the determining factor for the worst case. If a worst-case size cannot be isolated to a functional unit/strut geometry, perhaps due to irregular screw hole patterns or the shape of the plate, it is understandable that some tests would need to be modified, or possibly removed from test consideration, to accommodate the shape of the plate or the screw hole. Any test modifications or omissions shall be described in the final report with a rationale related to the plate’s anatomical use, indications, and functional requirements.1.1 This standard is intended to provide guidance for the static testing of small bone metallic plates used for fracture fixation. Small bone plates referred to in this standard would be used in minimally load-bearing anatomical areas of the far extremities, such as the fingers and toes, and in the cranium and upper face. Lower face/mandible, wrist, and ankle fixation plates would generally be larger and carry a substantial amount of load and should not be evaluated under this standard.1.2 ASTM Specification F382 and ISO 9585 are currently available for the testing of metallic bone plates as well, so the user can choose to use any of the tests in these standards for small bone plates. However, due to plate size, Specification F382 and ISO 9585 test setup and execution difficulty can be increased for small bone plates. Thus, this standard offers alternative test methods that are more appropriate for metallic bone plates used in small bone fracture fixation.1.3 This standard is not intended to address the mechanical performance of the plating construct or accessory components (for example, screws and wires).1.4 This standard is intended to provide a basis for the mechanical comparison of small bone plates. Due to the complex and varying biomechanics found in the areas of the body where these plates are used, this standard should only be used to compare the in vitro mechanical performance of small bone plates and not used to infer in vivo performance characteristics.1.5 This standard describes static tests by specifying load types and specific methods of applying these loads. Tests for evaluating and characterizing these loads include the following: static torsion, static cantilever beam bending, static lateral bending, and static three-point bending.1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.7 Multiple tests are cited in this standard. However, it must be noted that the user is not obligated to test using all of the described methods. Instead, the user should only select test methods that are appropriate for a particular device design.1.8 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
