• 1.B.3. Dimensional inspection machines, instruments, or systems, as follows:
• b. Linear displacement measuring instruments, as follows: 1. Non-contact type measuring systems with a “resolution” equal to or better (less) than 0,2 μm within a measuring range up to 0,2 mm; 2. Linear variable differential transformer (LVDT) systems having both of the following characteristics: a. 1. “Linearity” equal to or less (better) than 0,1 % measured from 0 to the full operating range, for LVDTs with an operating range up to 5 mm; or 2. “Linearity” equal to or less (better) than 0,1 % measured from 0 to 5 mm for LVDTs with an operating range greater than 5 mm; and b. Drift equal to or better (less) than 0,1 % per day at a standard ambient test room temperature ± 1 K; 3. Measuring systems having both of the following characteristics: a. Contain a laser; and b. Maintain for at least 12 hours, over a temperature range of ± 1 K around a standard temperature and a standard pressure: 1. A “resolution” over their full scale of 0,1 μm or better; and 2. With a “measurement uncertainty” equal to or better (less) than (0,2 + L/2 000 ) μm (L is the measured length in millimeters); Note: Item 1.B.3.b.3. does not control measuring interferometer systems, without closed or open loop feedback, containing a laser to measure slide movement errors of machine tools, dimensional inspection machines, or similar equipment. Technical Note: In Item 1.B.3.b. ‘linear displacement’ means the change of distance between the measuring probe and the measured object.
• c. Angular displacement measuring instruments having an “angular position deviation” equal to or better (less) than 0,00025°; Note: Item 1.B.3.c. does not control optical instruments, such as autocollimators, using collimated light (e.g., laser light) to detect angular displacement of a mirror.
