ISO 7637-2 Not applicable As specified in ISO 7637-2
a)
The test is applicable to all d.c. power ports intended to be connected permanently to cables longer than 3 m.
b)
All ME equipment and ME system cables shall be attached during the test.
c)
Internally powered ME equipment is exempt from this test if it cannot be used during battery charging, is of less than 0,4 m maximum dimenion including the maximum lenght of all cables
specified and has no connection to earth, telecommunications systems, any other equipment or a patient
d)
The test may be performed with the ME equipment or ME system powered at any one of its nominal input voltages.
e)
Testing may be performed at other modulation frequencies identified by the risk management process.
f)
For ME equipment and ME systems intended to be installed in passenger cars and light commercial vehicles including ambulances fitted with 12 V electrical systems or commercial vehicles
including ambulamces fitted with 24 V electrical systems.
g)
Direct coupling shall be used.
h)
r.m.s., before modulation is applied.
i)
If the frequency stepping skips over an ISM or amateur radio band, as applicable, an additional test frequency shall be used in the ISM or amateur radio band. This applies to each ISM and
amateur radio band within the specified frequency range.
j)
The ISM (industrial, scientific and medical) bands between 0,15 MHz and 80 MHz are 6,765 to 6,795 MHz; 13,553 to 13,567 MHz; 26,957 to 27,283 MHz; and 40,66 to 40,70 MHz.
The amateur radio bands between 0,15 and 80 MHz are 1,8 to 2,0 MHz; 3,5 to 4,0 MHz; 5,3 to 5,4 MHz; 7,0 to 7,3 MHz; 10,1 to 10,15 MHz; 14,0 to 14,2 MHz; 18,07 to 18,17 MHz;
21,0 to 21,4 MHz; 24,89 to 24,99 MHz; 28,0 to 29,7 MHz and 50,0 to 54,0 MHz.
