There are few published standards for defining sharpness. Some of these are intended for products that are supposed to be sharp, and some were written to prevent products from being sharp. In the latter case, UL Standard 1439 was an attempt to address unintended sharp edges on products. It was first issued in the early 1970s; since then several oth...
Materials, including skin, fail when they are contacted by an object that exceeds a certain stress. Stress is a measure of a force when it is applied over an area. Stress is what matters in sharpness, because even a large force will produce a low stress if it is spread out over a large enough area, and vice versa. Depending on the contact area, you...
Given the lack of appropriate standards for testing products for sharpness in high-force situations, engineers can consider novel approaches to testing product edges for safety. These tests also can be used to determine the effectiveness of personal protective equipment (PPE). Hand protection is outlined in the U.S Department of Labor’s OSHA Regula...
Seemingly innocuous products can cause debilitating injuries. Often these could have been avoided with a simple deburring operation. Obviously, the manufacturers did not intend for these injuries to happen, and of course manufacturers cannot foresee extreme misuse of their products. The solution is a comprehensive object safety review process as pa...
Sometimes as a manufacturer, you face a trade-off between safety and cost. You need to define the risks, and then decide how to address them. The costs of product safety can seem to conflict with profits. Yet the costs of deburring a part can be lower than the cost of settling an injury claim or suit. Victor Alexander Popp, PE, is a principal of VP...
Define Sharpness. Sharpness is a measure of the quality of an object’s edge or point. It is determined by the object’s ability to cut through a material with minimal force and to maintain its edge over time. In photography, sharpness is a measure of the clarity and detail of an image.
Define Acuity. Acuity refers to the clarity or sharpness of vision. It is the ability of the eye to distinguish fine details of an object, such as letters on a chart or the edges of a shape. Acuity is measured using various tests, including the Snellen chart, which displays letters of different sizes that a person is asked to read from a distance.
Sharpness refers to the quality of being physically sharp or pointed. It is the ability of an object to cut or pierce with ease. A knife with a sharp blade, for example, is able to slice through food effortlessly. Sharpness can also refer to the quality of being visually clear and distinct.
