a primary standard part in a construction technological group. Basic components can be standardized and unified parts, instruments, or attachments, or they may be similar or analogous parts of engines, machines, and the like (such as machine housings, cylinder blocks, or transmissions). Basic components are used for developing standard and special-instruction manufacturing processes and for determining the labor requirements of jobs (including the number of workers needed), the types and range of equipment needed, and the space requirements and other indicators needed in the designing of workshops and plants for specialized production; they also permit the making of more reliable estimates of the traffic capacity of particular workshops and other units.
