ECCN 2B206
NPATDimensional inspection machines, instruments or systems, other than those described in 2B006, as follows .
What This ECCN Covers
ECCN 2B206 controls dimensional inspection machines, instruments, or systems, other than those described in 2B006, meeting the criteria in the entry. These high-accuracy coordinate measuring systems have proliferation-relevant uses and are controlled for Nuclear Nonproliferation and Anti-Terrorism reasons.
Who needs to check this?
Suppliers of high-accuracy coordinate measuring machines and dimensional inspection systems for precision manufacturing.
Compliance tip
Rule out 2B006 first (and 2B996 for the AT-only tier), then confirm the measurement uncertainty against 2B206. With NP among the reasons, apply Part 744 nuclear end-use diligence and verify the Country Chart.
Items Covered
- a.Computer controlled or numerically controlled coordinate measuring machines (CMM) with either of the following characteristics:
- 1. Having only two axes with a maximum permissible error of length measurement along any axis (one dimension), 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. Having three or more axes with a three dimensional (volumetric) maximum permissible error of length measurement, identified as 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).
- 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 0.02°.
- c.Linear displacement measuring systems having both of the following characteristics:
- 1. Containing a "laser;" and
- 2. Capable of maintaining, for at least 12 hours over a temperature range of ± 1 K around a standard temperature and a standard pressure, both:
- 2.a. A "resolution" over their full scale of 0.1 µm or better; and
- 2.b. A "measurement uncertainty" equal to or better (less) than (0.2 + L/2,000) µm (L is the measured length in millimeters).
- d.Linear Variable Differential Transformer (LVDT) systems having all of the following:
- 1. Having any of the following:
- 1.a. "Linearity" equal to or less (better) than 0.1% measured from 0 to the full operating range, for LVDTs with a full operating range up to and including ±5 mm; or
- 1.b. "Linearity" equal to or less (better) than 0.1% measured from 0 to 5 mm for LVDTs with a 'full operating range' greater than ±5 mm; and
- 2. Drift equal to or less (better) than 0.1% per day at a standard ambient test room temperature ±1 K.
