# Council Regulation (EC) No 428/2009 of 5 May 2009 setting up a Community regime for the control of exports, transfer, brokering and transit of dual-use items (Recast), Division [2B206]: Dimensional inspection machines, instruments or systems, other than those specified in 2B006, as follows:

Extent: E+W+S+N.I.

a..Computer controlled or numerically controlled coordinate measuring machines (CMM) having either of the following characteristics:
1..Having only two axes and having a maximum permissible error of length measurement along any axis (one dimensional), identified as any combination of E0x,MPE, E0y,MPE, or E0z,MPE, equal to or less (better) than (1,25 + L/1 000) μm (where L is the measured length in mm) at any point within the operating range of the machine (i.e., within the length of the axis), according to ISO 10360-2:2009; or
2..Three or more axes and having a three dimensional (volumetric) maximum permissible error of length measurement (E0,MPE) equal to or less (better) than (1,7 + L/800) μm (where L is the measured length in mm) at any point within the operating range of the machine (i.e., within the length of the axis), according to ISO 10360-2:2009;
Technical Note:
The E0,MPE of the most accurate configuration of the CMM specified according to ISO 10360-2:2009 by the manufacturer (e.g., best of the following: probe, stylus, length, motion parameters, environments) and with all compensations available shall be compared to the (1,7 + L/800) μm threshold.
b..Systems for simultaneous linear-angular inspection of hemishells, having both of the following characteristics:
1.."Measurement uncertainty" along any linear axis equal to or less (better) than 3,5 μm per 5 mm; and
2.."Angular position deviation" equal to or less than 0,02o;
c..‘Linear displacement’ measuring systems having all of the following characteristics:
Technical Note:
For the purpose of 2B206.c. ‘linear displacement’ means the change of distance between the measuring probe and the measured object.
1..Containing a "laser"; and
2..Capable of maintaining, for at least 12 hours, over a temperature range of ± 1 K (± 1 °C) around a standard temperature and standard pressure, all of the following:
a..A "resolution" over their full scale of 0,1 μm or better; and
b..With a "measurement uncertainty" equal to or better (less) than (0,2 + L/2 000) μm (L is the measured length in mm).
Note:
2B206.c. 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.
d..Linear variable differential transformer (LVDT) systems having both of the following characteristics:
Technical Note:
For the purpose of 2B206.d. ‘linear displacement’ means the change of distance between the measuring probe and the measured object.
1..Having any of the following:
a.."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
b.."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
2..Drift equal to or better (less) than 0,1 % per day at a standard ambient test room temperature ± 1 K (± 1 °C).
Note 1:
Machine tools that can be used as measuring machines are controlled if they meet or exceed the criteria specified for the machine tool function or the measuring machine function.
Note 2:
A machine specified in 2B206 is controlled if it exceeds the control threshold anywhere within its operating range.
Technical Notes:
All parameters of measurement values in 2B206 represent plus/minus i.e., not total band.
