I.. SCOPE

1.1 Purpose. This standard establishes the documentation and design requirements for
the control of the electromagnetic emission and susceptibility characteristics of electronic,
electrical, and electromechanical equipment and subsystems (as defined herein) designed or
procured for use by activities and agencies of the Department of Defense. Such equipment
and, subsystems may be used independently or as an integral part of other subsystems or
systems.

1.2 Application. The requirements of this standard are applicable to the extent
specified in the individual equipment or subsystem specification, contract or order. The
applicability of the emission and susceptibility requirements are dependent upon the type of
equipment or subsystem and its mission and intended installation. When engineering analyses
on equipment or subsystems being procured for use in specific systems or platforms reveal
that the requirements in this standard are not adequate for that procurement, they may be
tailored by the procuring activity and incorporated into the request-for-proposal, specifi-
cation, contract or order. In cases where s system or integrating contractor is required
to prepare a detailed equipment or subsystem specification containing requirements for
electromagnetic Compatibility (EMC),. including electromagnetic interference (EMI), electro-
magnetic pulse (EMP), electromagnetic (E11) radiation hazards, and so forth, the requirements
of this standard shall be tailored as needed to achieve overall required system or platform
performance. For equipment and subsystems in feasibility or advanced development stages
of the acquisition process, this standard shall be used as a guide in formulating the
appropriate requirements. Those requirements shall be enumerated in the individual equip-
ment development or purchase description.

1.3 Units. Symbols, units, and physical constants used in this standard are in
accordance with the International System of Units (SD, as described in MIL-STD-463.

1.4 Emission and susceptibility designations. The emission and susceptibility

requirements in this standard and corresponding test methods of MIL-STD-462 are designated
in accordance with an alpha-numeric coding system where:

C a Conducted
II a Radiated .
E a Emission
S a Susceptibility
UM - Unique requirement(s) intended for a miscellaneous,
general-purpose equipment or subsystem

MIL-STD-4610

3.6 Subsystem. For the purpose of this standard; the definition in 3.6a or 3.66 shall
be considered as a subsystem. In either case, the devices or equipment may be physically
separated when in operation and will be installed in fixed or mobile stations, vehicles, or
systems.

a. A collection of devices or equipment designed and integrated to function as a

• single entry, but wherein any device or equipment is not required to function
as an individual equipment, as defined in 3.2.

b.• A collection of equipment and subsystems, as defined in 3.6a, designed and

integrated to function as a major subdivision of a system and to perform an
operational function, or functions, therein. •

3.7 Sy stem. A composite of equipment, subsystems, skills, and techniques capable of

performing or supporting an operational role. A complete' system includes related facilities,
equipment, subsystems, materials, services; and personnel required for its operation to the
degree that It can be considered self-sufficient within its operational or support environment.
(EMC requirements for systems are not included in this standard, but rather in such documents
as MIL-E-6051, MIL-STD-1541, and MIL-STD-1542.)

3.8 Tailoring. The process by which the requirements of this standard are adapted (that
is, modified, deleted, or supplemented) to the peculiarities, characteristics, or operational
requirements of the material in an individual equipment or subsystem specification. The
tailoring process does not constitute a waiver or deviation. The latter terms are defined in
MIL-STD-480.

3.9 Telecommunications equipment. Any equipment which transmits, emits, or receives

signs, signals, writing; images, sounds, or information of any nature by wire, radio, visual,
or other electromagnetic means.

4.3.1 Filtering (Navy only!. The use of line-to-ground filters for EMI control shall be
minimized. Such filters establish low impedance paths for structure (common-mode) currents
through the ground plane and-can be a major cause- of interference in systems, platforms, or
installations because the currents can couple into other equipment using the same ground
plane. If such a filter must be employed, the total line-to-ground capacitance shall not
exceed 0.1 microfarads (u s ) for 60 hertz (Hz) equipment or 0.02 pF for 400 Hz equipment. The
filtering. employed shall be fully-described in the equipment or subsystem technical manual,

MIL-STD-461C

4.3.2.2 Navy procurements. Compliance with MIL-STD-1385 shall be accomplished, and

OD 30393 shall be used as a design guide in implementing the principles outlined in MIL-
STD-1385. In addition, MIL-STD-1377 shall be used to determine the effectiveness of cable,
connector, and weapon enclosure shielding and filtering. For air weapons, all circuits shall
be isolated from the equipment or subsystem case, and the case bonded to the airframe.

4.3.2.3 Army procurements. The requirements of 4.1.2.1 and 4.3.2.2 shall be used as
specified in the procurement documentation.

4.4 Self-compatibility. The operational performance of an equipment or subsystem shall

not be degraded, nor shall it malfunction when all of the units or devices in the equipment
or subsystem are operating together at their designed levels of efficiency or their nominal
design capability.

4.5 Commercial off-the-shelf equipment.

4.5.1 Used in equipment or subsystems.

4.5.1.1 Selected by contractor. When it is demonstrated by the contractor that a

commercial item selected by the contractor is responsible for an equipment or subsystem
failing to meet its contractual EMI requirements, either the commercial item shall be modified
or replaced or interference suppression measures shall be employed, so that the equipment or
subsystem can meet its contractual EMI requirements.

4.5.1.2 Specified by procuring activity. When it is demonstrated by the contractor

that a commercial item specified by the procuring activity for use in an equipment or sub-
system is responsible for failure of the equipment or subsystem to meet its contractual EMI
requirements, the data indicating such failure shall he included in the EM/ Test Report. No
modification not replacement shall be made unless authorized by the procuring activity.

4.5.2 Used as an individual equipment. Commercial equipment without any previous EMI
certification shall meet the applicable requirements in Parts 2 through 10 of this standard.

4.6 Government furnished equipment (an). When it is demonstrated by the contractor

that a GEE is responsible for failure of an equipment or subsystem to meet its contractual
EKI requirements, the data indicating such failure, along with descriptions of possible
modifications to the GFE, shall be included in the EMI Teat Report. No modification shall be
made unless authorized by the procuring activity.

4.7 Short-duration emissions. Radiated and conducted transient emissions, resulting

from automatic cycling of electronic or electrical switching circuitry and manually controlled
operational mode switching functions required for normal operation of the equipment or sub-
system, shall meet all applicable requirements of this standard.

4.8 Procurements of equipment or subsystems having mat other EMI requirements.

Procurements of production-type equipment and subsystems electrically and mechanically
identical to those previously procured by activities of DoD or other Federal agencies, or
their contractors, shall meet the EMI requirements and associated limits, as applicable in
the earlier procurement, unless otherwise specified by the Command or agency concerned.
For Navy procurements, production-type equipment shall be tested to all the applicable
limits of this standard, but shall meet the EMI requirements and associated limits as
applicable in the earlier procurement, unless otherwise specified by the Command or agency
concerned. All data shall be provided is the Eta Test Report.

4.9 Testing requirements. The testing requirements and procedures of MIL-STD-462, as

implemented by a Government approved Eta Test Plan (See 6.2), shall be used to determine
comp/lance with the applicable emission and susceptibility requirements of Section 5 and
Parts 2 through 10 of this standard. When performing susceptibility testing, the thresholds
of susceptibility shall be determined mad reported in the EMI Test Report, whether below
the contractual EMI requirement or above, within the maximum capability of the test equipment
used. Data gathered as a result of performing tests in one electromagnetic discipline may be
sufficient to satisfy requirements In another. Therefore, to avoid unnecessary duplication,
a single test program should be established with similar tests conducted concurrently
whenever possible. Equipment that are intended to be operated as a subsystem shall be
tested, as such, to the applicable emission and susceptibility requirements and limits
whenever practical. Formal testing is not to commence without approval of the test plan
by the Command or agency concerned.

1. SCOPE

This part of MIL-STD-461 supplements Part 1 of the standard by defining

emission and susceptibility requirements and limits for equipment and
subsystems intended for use aboard aircraft (class Al), including associated
non-shipboard ground support equipment and for class A3 equipment and
subsystems procured for the Air Force.

LI Determining requirements

1.1.1 Air Force and Navy procurements. Table 2-1 defines categories of
class Al equipment and subsystems. Table 2-11 shall be used to determine
the requirements applicable for equipment and subsystems procured for Air
Force or Navy use. The table also denotes the paragraphs where in the
requirements and limits are defined. A '7" entry in the table means the
requirement is applicable, and the limit shall be met using the procedures
in MIL-STD-462 or the approved EMI Test Plan. A 1 7/. " entry means the
applicability of the requirement is limited and is specified in the appro-
priate corresponding paragraph. The limit shall be met using the proce-
dures in MIL-STD-462 or the approved EMI Test Plan. A "1" entry means
that the applicability of the requirement must be determined on a case-by-
case basis and, if the requirement is to be imposed, it must so specified in
the appropriate procurement document. When required, the limit shall be met
using the procedures in MIL-ST0-462 or the approved EMI Test Plan. Absence
of an entry means the requirement is not applicable.

1.1.2 Army procurement's. Table 2-111 ,shall be used to determine the specific
requirements for class Al equipment and subsystems procured for Army use.
The table also denotes the paragraphs wherein the requirements and limits
are defined. A "Y" entry in the table means the requirement is applicable,
and the limit shall be met using the procedures in MIL-STD-462 or the approved
ENI test plan. A Y entry means the applicability of the requirement is
limited and is specified in the appropriate corresponding paragraphs. When
applicable the limit shall be met using the procedures in MIL-STD-462 or the
approved ENI test plan. A "T" entry means that the applicability must be
determined on a case-by-case basis and, if the requirement is to be imposed,
it must be specified in the appropriate procurement document. When required,
the limit shall be met using the procedures in MIL-S1D-462 or the approved
ENI Test Plan. Absence of an entry means the requirement is not applicable.
For procurements of subsystems, such as radar, LW, surveillance, navigation,
and the like, comprised of individual equipment listed in table 2-111, the
applicable emission and susceptibility requirements for the subsystem shall be
tailored by the procuring activity based on the requirements of the individual
equipment.
2. CE01 (limited applicability)

2.1 CE01 applicability. This requirement is applicable for equipment

and subsystems installed on aircraft having an anti-submarine warfare
(ASW) capability and for Navy equipment and subsystems intended for use on
aircraft and having Very Low Frequency ( VLF) subsystems and equipment. When
required, CE01 is applicable only for narrowband emissions between 30 Hz and
15 kilohertz (kHz) on alernating current (AC) and direct current (DC) leads,
which obtain power from other sources or provide power to other equipment or
subsystems; grounds or neutrals, which are not grounded internally to the
subsystem or equipment being measured; and, for Army and Navy procurements,
interconnecting control leads which provide AC and DC power from or to the
test sample. The requirement is not applicable for interconnecting signal
leads such as clock, IF, audio, firing, digital, RI, and the like, unless
otherwise specified by the Command or agency concerned.

2.2 CE01 limits

2.2.1 AC, DC, and interconnecting control leads. Electromagnetic emissions

shall not appear on AC, DC, and, where required, interconnecting control
leads in excess of the values as shown on figure 2-1. The limits shall be
met when measured with an effective bandwidth not exceeding the primary
power frequency plus 20% of the power frequency for AC power leads or 75 Hz
for DC power leads.

2.2.2 Interconnecting signal leads. If compliance with this requirement

is required for signal leads, limits shall developed on a case-by-case basis
considering the intentional transmission, its specified power level, necessary
information bandwith, and pulse rise time. Such limits must be approved by
the Command or agency concerned.

duration is the time interval between the 502 amplitude point on the
transient leading edge and the 502 amplitude point on the transient trailing
edge; high frequency ringing superimposed on the pulse leading or trailing
edges should be ignored.

6. - CSOI (limited applicability)

6.1 CSOI applicability. This requirement is applicable to equipment

and subsystem AC and DC power leads, including grounds and neutrals which
are not grounded internally to the equipment or subsystem. This requirement
is not applicable within ±5 percent of the power frequency(ies). For Navy
procurements, this requirement may be deleted for AC leads, with the
approval of the command or agency concerned, if no circuit within the
equipment or system is more sensitive than 100 millivolts (mV). For
equipment and subsystems procured solely for Army use, this requirement is
applicable for DC leads only.

6.2 CSOI lirits. The test sample shall not exhibit any malfunction,
degradation of performance, or deviation from specified from specified
indications, beyond the tolerances indicated in the individual equipment or
subsystem specification, when subjected to electromagnetic energy injected
onto its power leads equal to the values on figure 2-4. The requirement is
also met when the power source specified in CSOI of MIL-STD-462, adjusted to
dissipate 50 watts in a 0.5 ohm load, cannot develop the required voltage at
the test sample power input terminals, and the test sample is not susceptible
to the output of the signal source.
