The Conference National Board (NBE) – Management And Merchandising & Casket Parts Practice Test

Non-ferrous casket thickness is described by weight per area: ounces per square foot. This standard ties the sheet metal’s thickness to how heavy a given area of the metal is, which works well across different non-ferrous metals like copper, bronze, and aluminum that have different densities. Using a weight-per-area measure lets you compare thicknesses consistently even when the metals themselves weigh differently. Inches or millimeters are direct thickness measurements, but they don’t account for density differences between metals, so they’re less practical for non-ferrous materials in this context. Gauge is a separate system historically used for ferrous metals and doesn’t translate consistently across different non-ferrous metals, making it less suitable for describing their thickness.
