| Bust Coil | (english) Coils removed from the off-gauge reel. The BUST (build up side trimmer) coil contains defects (gauge variation and quality defects) and off-spec widths. |
| Brittle: | (english) A brittle structure or material exhibits low ductility, meaning that it exhibits very little inelastic deformation before complete failure. |
| Ductility: | (english) Ductility generally refers to the amount of inelastic deformation which a material or structure experiences before complete failure. Quantitatively, ductility can be defined as the ratio of the total displacement or strain at failure, divided by the displacement or strain at the elastic limit. |
| Energy: | (english) A property of a body related to its ability to move a force through a distance opposite the force's direction; energy is the product of the magnitude of the force times the distance. Energy may take several forms: see kinetic energy, potential energy, and elastic energy. |
| Flexibility: | (english) Flexibility is the inverse of stiffness. When a force is applied to a structure, there is a displacement in the direction of the force; flexibility is the ratio of the displacement divided by the force. High flexibility means that a small load produces a large displacement. |
| Stability: | (english) Stability is best defined as the opposite of instability, which is the occurrence of large structural deformations which are not the result of material failure. |
| Transmissibility: | (english) The principle stating that a force has the same external effect on an object regardless of where it acts along its line of action. |
| Aromatic | (Environmental Engineering) A form of bonding in which ring compounds share electrons over more than two atoms. The electrons are delocalized. This leads to unusual ring stability. |
| POTW | (Environmental Engineering) or Publicly Owned Treatment Works Any municipally owned wastewater treatment facility. |
| Primary standards | (Environmental Engineering) Required drinking water quality standards related directly to human health. These standards are required and enforceable by the U.S. EPA. See secondary standards. |
