Relevant Notes for interpreting this DSGL Item

GENERAL NOTES

​​​​Definitions

Terms in “quotation marks” are defined terms (see Definitions). Words and terms that are defined and that appear in the Defence and Strategic Goods List without quotation marks are intended to take their ordinary dictionary meanings.


​​ Notes​

​​​The Notes, Technical Notes and Nota Bene (N.B.) appearing in the Defence and Strategic Goods List form an integral part of the control text.


Incorporated goods​

The object of the controls contained in the Defence and Strategic Goods List should not be defeated by the export of any non‑controlled goods (including plant) containing one or more controlled components when the controlled component or components are the principal element of the goods and can feasibly be removed or used for other purposes.​​

N​ote​:​      In judging whether the controlled component or components are to be considered the principal element, it is necessary to weigh the factors of quantity, value and technological know‑how involved and other special circumstances which might establish the controlled component or components as the principal element of the goods being procured.​


New and used goods

Goods specified in the Defence and Strategic Goods List include both new and used goods.


CAS numbers

In some instances chemicals are listed by name and CAS number. The list applies to chemicals of the same structural formula (including hydrates) regardless of name or CAS number. CAS numbers are shown to assist in identifying a particular chemical or mixture, irrespective of nomenclature. CAS numbers cannot be used as unique identifiers because:

   (a)some forms of the listed chemical have different CAS numbers; and

   ​(b)​mixtures containing a listed chemical may also have different CAS numbers.​

​ ​​

Source Code

“Source code” items are controlled either by “software” or by “software” and “technology” controls, except when such “source code” items are explicitly decontrolled.​​


Medical equipment

Equipment specially designed for medical end use that incorporates an item controlled in the Dual Use List is not controlled​​​.​​​

General “information security” note (GISN)

"Information security" items or functions should be considered against the provisions in Category 5 Part 2, even if they are components, "software" or functions of other items.

Note(s) to PART 2 Dual Use List

​​Rel​ocated.​​

Note(s) to 2B - Test, Inspection and Production Equipment

​Technical Notes:

1. Secondary parallel contouring axes, (e.g., the w‑axis on horizontal boring mills or a secondary rotary axis the centre line of which is parallel to the primary rotary axis) are not counted in the total number of contouring axes.  Rotary axes need not rotate over 360°.  A rotary axis can be driven by a linear device (e.g., a screw or a rack‑and‑pinion).

2. For the purposes of 2B, the number of axes which can be co‑ordinated simultaneously for “contouring control” is the number of axes along or around which, during processing of the workpiece, simultaneous and interrelated motions are performed between the workpiece and a tool.  This does not include any additional axes along or around which other relative movement within the machine are performed such as:

a.  Wheel‑dressing systems in grinding machines;

b.  Parallel rotary axes designed for mounting of separate workpieces;

c.  Co‑linear rotary axes designed for manipulating the same workpiece by holding it in a chuck from different ends.

3. Axis nomenclature shall be in accordance with International Standard ISO 841:2001, Industrial automation systems and integration - Numerical control of machines - Coordinate system and motion nomenclature.​

4. For the purposes of 2B001 to 2B009 a “tilting spindle” is counted as a rotary axis.

5. 'Stated "unidirectional positioning repeatability"' may be used for each machine tool model as an alternative to individual machine tests, and is determined as follows:​

a.  Select five machines of a model to be evaluated;

b.  Measure the linear axis repeatability (R↑,R↓) according to ISO 230-2:2014 and evaluate "unidirectional positioning repeatability" for each axis of each of the five machines;​

c.  Determine the arithmetic mean value of the "unidirectional positioning repeatability"-values for each axis of all five machines together. These arithmetic mean values of "unidirectional positioning repeatability" (UPR) become the s​tated value of each axis for the model (UPR​, UPR, …)​

d.  Since the Category 2 list refers to each linear axis there will be as many 'stated "unidirectional positioning repeatability"'-values as there are linear axes;​

e.  If any axis of a machine model not specified by 2B001.a. to 2B001.c. has a 'stated "unidirectional positioning repeatability"' equal to or less than the specified "unidirectional positioning repeatability" of each machine tool model plus 0.7 µm, the builder should be required to reaffirm the accuracy level once every eighteen months.​

6. For the purposes of 2B., measurement uncertainty for the "unidirectional positioning repeatability" of machine tools, as defined in the International Standard ISO 230-2:2014 or national equivalents, shall not be considered.​

7. For the purpose of 2.B., the measurement of axes shall be made according to test procedures in 5.3.2. of ISO 230-2:2014. Tests for axes longer than 2 meters shall be made over 2 m segments. Axes longer than 4 m require multiple tests (e.g., two tests for axes longer than 4 m and up to 8 m, three tests for axes longer than 8 m and up to 12 m), each over 2 m segments and distributed in equal intervals over the axis length. Test segments are equally spaced along the full axis length, with any excess length equally divided at the beginning, in between, and at the end of the test segments. The smallest "unidirectional positioning repeatability"-value of all test segments is to be reported.​

8. 'Stated positioning accuracy' derived from measurements made according to ISO 230/2:2014 or national equivalents may be used for each machine tool model as an alternative to individual machine tests. 'Stated positioning accuracy' means the accuracy value provided to national licensing authorities as representative of the accuracy of a specific machine model.

   Determination of 'Stated Positioning Accuracy'

a. Select five machines of a model to be evaluated;

b. Measure the linear axis accuracies according to ISO 230/2:2014;

c. Determine the A-values for each axis of each machine. The method of calculating the A-value is described in the ISO standard;

d. Determine the mean value of the A-value of each axis. This mean value Ā becomes the stated value of each axis for the model (Āx Āy...);

e. Since the Category 2 list refers to each linear axis there will be as many stated values as there are linear axes;

f. If any axis of a machine model not specified by 2B201.a. to c. has a stated positioning accuracy of 6 μm or better (less) for grinding machines, and 8 μm or better (less) for milling and turning machines, both according to ISO 230/2:2014, then the builder should be required to reaffirm the accuracy level once every eighteen months.

9. For the purposes of 2B201., measurement uncertainty for the positioning accuracy of machine tools, as defined in the International Standard ISO 230/2:2014 or national equivalents, shall not be considered.
