This specification covers glass graduates suitable for laboratory, pharmaceutical, and other uses, in both conical and cylindrical shapes. Graduates shall be in the following types: type 1 - graduated in metric scale only, and type 2 - graduated in both metric and inch-pound scales. Graduates having a capacity of more than 15 mL (4 fluid drams) may be either conical or cylindrical. Those having a capacity of 15 mL or less shall be cylindrical. Each graduate shall have clear graduation markings perpendicular to the vertical axis of the graduate and parallel to each other. Capacities, graduation ranges, values of graduated intervals, and numbered graduations applicable to single-scale graduates and to appropriate portions of double-scale graduates are presented in details.
