Definitions: |
|
|
|
|
|
|
Port: |
Particular
interface of the specified apparatus with the
external |
|
|
|
electromagnetic
environment. |
|
|
|
|
|
|
|
|
|
|
Enclosure port: |
The physical
boundary of the apparatus which electromagnetic
fields may |
|
|
radiate through
or impinge on. |
|
|
|
|
|
|
|
|
|
|
Cable port: |
A point at which
a conductor or cable is connected to the
apparatus. |
|
|
Example are
signal,control and power ports. |
|
|
|
|
|
|
|
|
|
Public mains |
Electricity
lines to which all categories of consumers have
access and |
|
network: |
which are
operated by supply or distribution undertaking
for the purpose |
|
|
of supplying
electrical energy. |
|
|
|
|
|
|
|
|
|
|
Functional |
A point on the
apparatus which is connected to earth for the
purposes |
|
earth port: |
other than
electrical safety. |

Performance criteria: |
|
|
|
|
|
|
A: |
The apparatus
shall continue to operate as intended. No
degradation of |
|
|
performance or
loss of function is allowed below a performance
level |
|
|
specified by the
manufacturer, when the apparatus is used as
intended. |
|
|
The performance
level may be replaced by a permissible loss of |
|
|
|
performance. If
the minimum performance level or the permissible |
|
|
|
performance loss
is not specified by the manufacturer then either
of |
|
|
these may be
derived from the product description and
documentation |
|
|
and what the
user may reasonable expect from the apparatus if
used as |
|
|
intended. |
|
|
|
|
|
|
|
|
|
|
|
|
B: |
The apparatus
shall continue to operate as intended after the
test. No |
|
|
degradation of
performance or loss of function is allowed below
a |
|
|
|
performance
level specified by the manufacturer, when the
apparatus is |
|
|
used as intended.
The performance level may be replaced by a |
|
|
|
permissible loss
of performance. During the test, degradation of |
|
|
|
performance is
however allowed. No change of actual operating
state or |
|
|
stored data is
allowed. If the minimum performance level of the |
|
|
|
permissible
performance loss is not specified by the
manufacturer then |
|
|
either of these
may be derived from the product description and |
|
|
|
documentation
and what the user may reasonable expect from the |
|
|
apparatus if
used as intended. |
|
|
|
|
|
|
|
|
|
|
C: |
Temporary loss
of function is allowed, provided the function is
self |
|
|
|
recoverable or
can be restored by the operation of controls. |

NOTE
1. Applicable only to apparatus containing
devices susceptible to magnetic fields, such as
Hall |
|
elements,
electrodynamic microphones, magnetic field
sensors, etc. |
|
NOTE
2. For CRTs the acceptable jitter depends upon
the character size and is computed for a test |
|
level of 1A/m
as follows: |
|
|
|
|
|
Jitter (mm) = [3
x character size (mm) + 1]/40 |
|
|
|
|
As jitter
is linearly proportional to the magnetic field
strength tests can be carried out at other |
|
test levels
extrapolating the maximum jitter level
appropriately. |
