Standardization usually starts within a company as a way to reduce costs associated with parts stocking, design drawings, training, and retraining of personnel. The next level might be a cooperative agreement between firms making similar equipment to use standardized dimensions, parts, and components. | Table Dielectric Constants of Solids in the Temperature Range 17-22 C From 1 .
