4A Systems, Equipment and Components

4A001 Electronic computers and related equipment, having any of the following and "electronic assemblies" and specially designed components therefor:

a. Specially designed to have any of the following:

1. Rated for operation at an ambient temperature below 228 K (-45 °C) or above 358 K (85 °C); or

2. Radiation hardened to exceed any of the following specifications:

a. Total Dose 5 × 10³ Gy (silicon);

b. Dose Rate Upset 5 × 10E6 Gy (silicon)/s; or

c. Single Event Upset 1 × 10 E–8 Error/bit/day;

b. Not used.

4A003 "Digital computers", "electronic assemblies", and related equipment therefor, as follows and specially designed components therefor:

a. Not used;

b. "Digital computers" having an "Adjusted Peak Performance" ("APP") exceeding 12,5 Weighted TeraFLOPS (WT);

c. "Electronic assemblies" specially designed or modified for enhancing performance by aggregation of processors so that the "APP" of the aggregation exceeds the limit specified in 4A003.b.;

d. Not used;

e. Not used;

f. Not used;

g. Equipment specially designed for aggregating the performance of “digital computers” by providing external interconnections which allows communications at unidirectional data rates exceeding 2,0 Gbyte/s per link.

4A004 Computers as follows and specially designed related equipment, "electronic assemblies" and components therefor:

a. "Systolic array computers";

b. "Neural computers";

c. "Optical computers".

4A005 Systems, equipment, and components therefor, specially designed or modified for the generation, operation or delivery of, or communication with, "intrusion software".

4A101 Analogue computers, "digital computers" or digital differential analysers, other than those specified in 4A001.a.1., which are ruggedized and designed or modified for use in space launch vehicles specified in 9A004 or sounding rockets specified in 9A104.

4A102 "Hybrid computers" specially designed for modelling, simulation or design integration of space launch vehicles specified in 9A004 or sounding rockets specified in 9A104.

Note 1:

Computers, related equipment and "software" performing telecommunications or "local area network" functions must also be evaluated against the performance characteristics of Category 5, Part 1 (Telecommunications).

Note 2:

Control units which directly interconnect the buses or channels of central processing units, "main storage" or disk controllers are not regarded as telecommunications equipment described in Category 5, Part 1 (Telecommunications).

N.B.:

For the control status of "software" specially designed for packet switching, see 5D001.
