Statement of Shuttle Mainboard via the EMI Test
Shuttle mainboards have been via the EMI test in terms of series of regulations: EN55022/
CISPR22/AS/NZS3548 Class B, EN55024 (1998/AS/NZS), EN4252.1 (1994), EN61000, ANSI
C63.4 (1992), CFR47 Part 15 Subpart B, and CNS13438 (1997). The items tested are illus-
trated as follows:
(A) Voltage: AC 110V/60HZ & AC 230V/50HZ
