Regulation 8 Amendments to Category 2 - Materials Processing

(1)

The section headed Category 2 - Materials Processing is amended as follows.

(2)

In the section headed 2B Test, Inspection and Production Equipment, after entry 2B352, insert—

“

2B510 Additive manufacturing equipment, designed to produce metal or metal alloy components, having all of the following, and specially designed components therefor:
a. Having at least one of the following consolidation sources:
1. “ Lasers”;
2. Electron beam; or
3. Electric arc;
b. Having a controlled process atmosphere of any of the following:
1. Inert gas; or
2. Vacuum (equal to or less than 100 Pa);
c. Having any of the following 'in-process monitoring' equipment in a 'coaxial configuration' or 'paraxial configuration':
1. Imaging camera with a peak response in the wavelength range exceeding 380 nm but not exceeding 14 000 nm;
2. Pyrometer designed to measure temperatures greater than 1 273,15 K (1 000°C); or
3. Radiometer or spectrometer with a peak response in the wavelength range exceeding 380 nm but not exceeding 3 000 nm; and
d. A closed loop control system designed to modify the consolidation source parameters, build path, or equipment settings during the build cycle in response to feedback from 'in-process monitoring' equipment specified in 2B510.c.

Technical Notes:

For the purposes of 2B510:

1. 'In-process monitoring', also known as in-situ process monitoring, pertains to the observation and measurement of the additive manufacturing process including electromagnetic or thermal emissions from the melt pool.
2. 'Co-axial configuration', also known as on-axis or inline configuration, pertains to one or more sensors that are mounted in an optical path shared by the “laser” consolidation source.
3. 'Paraxial configuration' pertains to one or more sensors that are physically mounted onto or integrated into the “laser”, electron beam or electric arc consolidation source component.
4. For both 'co-axial configuration' and 'paraxial configuration', the field of view of the sensor(s) is fixed to the moving reference frame of the consolidation source and moves in the same scan trajectories of the consolidation source throughout the build process.

In the section headed 2D Software, in entry 2D001.a., for “2A001 or 2B001 to 2B009” substitute “2A001, 2B001 to 2B009 or 2B510”.

(4)

In the section headed 2E Technology, after the Technical Note to the table (Deposition techniques) that appears after entry 2E301, insert—

“

2E503 “Technology”, as follows:
g. “Technology”, not specified elsewhere, for the “development” or “production” of ‘coating systems’ having all of the following:
1. Designed to protect ceramic “matrix” “composite” materials specified in 1C007 from corrosion; and
2. Designed to operate at temperatures exceeding 1 373,15 K (1 100°C).

Technical Note:

For the purposes of 2E503.g.,‘coating systems’ consist of one or more layers (e.g., bond, interlayer, top coat) of material deposited on the substrate.
