U. S. ARMY TEST AND EVALUATION COMMAND


COMMODITY ENGINEERING TEST PROCEDURE
FUZES
1.

OBJECTIVE

The objective of this MTP is to provide testing and evaluation


procedures for determining whether artillery, mortar, and recoiless rifle
ammunition fuzes meet the requirements of QMR's, SDR's, and TC's, particularly in the area of safety and reliability.
2.

BACKGROUND

The fuze is a physical system containing a device(s) that predicts or senses a target and initiates the functioning of a projectile.
It
performs this function before, upon or shortly after impact, at a certain
time interval, or by an electronic signal.
A fuze is required for almost all artillery, mortar, and recoilless rifle
projectiles.
When assembled to the projectile it functions
as an integral part of the projectile.
For the projectile to inflict the
desired effects on, or damage to, a target, much depends upon fuze reliability in initiating the functioning of the projectile at the most effective
time and place.
For this reason it is desirable to test a fuze in conjunction
with the tactical projectile(s) for which it is to be used, especially when
both are undergoing engineering testing.
A fuze system usually contains one or more mechanical, electromechanical, or electronic devices for target sensing and initiation of functioning.
A fuze that contains a multiple device providing an option in
initiation may be set for the type of initiation desired by use of a screwdriver, by hand, or by fuze setter.
Fuzes may also be designed to incorporate
features that result in muzzle action, definite delay times to complete the
function, delayed arming for safety, self-destruction antijamming, etc.
Fuze
designs usually contain at least two independent safety features activated
by separate forces when possible.
Usually, longitudinal and rotational
accelerations are employed.
The fuze generally contains the most sensitive
explosives of the projectile; i.e., detonators, relays, leads, primers, and
booster, combinations of which are referred to as the "explosive train."
Except for special applications, fuzes are attached to the profectile by the use of matching machined threads universal to most projectiles
and fuzes.
This permits interchangeability of fuzes with the various
projectiles.

PROCEDURES

6.1

PREPARATION FOR TEST

6.1.1

Design Review

A prerequisite for formulating an engineering test (ET) for a


fuze is that testing agency become familiar with the design agency's fuze
design principles, product improvement objectives when they apply, technical
characteristics, and weapon systems applicable to the fuze, as well as the
QMDO, QMR, SDR, MIL-STD, and other publications pertaining to fuze design
and requirements.
The most important launch parameters affecting fuze performance
are projectiel setback and spin. In the planning of tests, emphasis is
placed on testing in weapon systems that produce conditions of maximum setback, maximum spin, minimum setback, and minimum spin. This information may
be obtained from Figures 1 and 2, supplemented by Report DPS-2611 (reference
41).
Other factors to be considered are effects of firing from worn weapon
tubes, propelling charges with widely different burning characteristics (as
evidenced by time-pressure data), and effects of various zone charges (for
zoned ammunition); similarity of weapon tube length, twist of rifling, projectile design differences with possible effects on launching and flight
conditions, and other dissimilarities in the internal and external ballistics
of the system.
6.1.2

Training and Familiarization of Personnel

Ensure that test personnel are trained in the operation of the


test item in accordance with technical documentation available to include:
a.

TEST CONDUCT

6.2.1

Safety Evaluation

The philosophy and necessity for a safety evaluation as explained


in MTP 4-2-504 is applicable to fuzes.
Fuze safety is of paramount importance.
The fuze must not create a hazard during storage, transport,

0

handling, launch, or flight.
The safety data may be used to supplement
functioning data (paragraph 6.2.3) and vice versa if test results are satisfactory and applicable.
The criteria for determining fuze safety include
the following:
a.
The fuze shall not function as a result of nondestructive
conditioning tests performed prior to firing the round.
b.
To be considered launch safe, the fuze shall not function
prematurely in the bore of the weapon (except for special ammunition specifically designed to do so).
c.
To be considered flight safe, a fuze shall not function in
flight after safe separation and before impact with the target or, when
applicable, at a specific time prior to mean flight time which is consistent
with design requirements, at a rate greater than that permitted in the appropriate QMR, SDR, or product improvement plan.
If no flight completion
is specified, it will be assumed that the fuze must not function before
reaching 90% of the predicted mean flight time.
NOTE:

Some QMR's and SDR's require that the flight trajectory


be considered as being comprised of three zones when
judging the flight safety of a fuze.
Trajectory zones
near the gun and near the target, under which the probability of causing a casualty to tactically dispersed
troops is PL or greater with X% assurance, are considered
a matter of safety.
The mid-range under which the probability of a casualty is less than P L is considered only
as affecting reliability.
Assumptions as to troop disposition and concealment and acceptable values of PL and
X are determined with the aid of USACDC.

d.
During launch or flight, a fuze shall not separate nor shall
components become detached to the extent that erratic flight of the projectile
occurs or friendly troops are endangered.
e.
Delay arming safety devices must operate within specified
design limitations of the fuze.
f.
If, during handling tests, the fuze or cartridge is deformed
to the extent that the round cannot be fired, it shall be safe to handle and
dispose of.
To achieve the desired statistical confidence in the safety of
the test item would require a sample size that is uneconomically large and
impractical to test.
Thus, the total safety evaluation must encompass not
only firing tests of reasonable proportions, but engineering judgment based
upon other factors as well.
The safety evaluation of fuzes which leads to a
Safety Release (see MTP 4-2-504) involves the following procedures.
6.2.1.1

Preparation for Test

a.
Design Review - The design of the test item is studied to
determine which components have adequately proven themselves in designs of
other fuzes, and which are relatively untried and deserving of more attention.

3 December 1970
Test results of similar fuzes and fuze components are studied to determine
the extent to which these results may add to confidence in the safety of
the fuze.
b. Review of Prior Testing - MIL-STD-331 required that a number
of laboratory and field tests be conducted on fuzes.
During these test, the
fuze is not always assembled to its intended projectile (e.g., during drop,
vibration, jolt, jumble and other tests). The laboratory tests are normally
conducted by the developing agency who should provide information on satisfactory performance of the futes. Any tests not conducted by the developer
should be performed during the ET. Laboratory safety tests of projectile
fuzes in MIL-STD-331 are designated by Tests 101 through 115, field test
data from Tests 207, 208, and 210 are also sometimes available.
In additiom to the tests of MIL-STD-331, all field data from
engineer design tests (EDT) and other tests are considered in evaluating
the safety of the item.
c. Safety Statement - AMC Regulation 385-12 requires the subm
mission of a Safety Statement from the developer prior to the commencement
of the ET. Review of the Safety Statement is mandatory in conncection with
the design review prescribed in a, above.
6.2.1.2

Radio Freqency Radiation Hazard Test

For fuzes containing electronic components, the possibility exists


that electromagnetic radiation may initiate the fuze. To assure that this is
not true of the fuze under investigation, conduct the test for radiofrequency radiation initiation in accordance with the procedures outlined
in MTP 3-2-615.
6.2.1.3

Exposure and Firing Tests

The most extensive safety tests are conducted during the ET with
the fuze assembled to the round. The same lot of fuzes intended for the
service test (ST) are used. In this way the safety release recommendation is
applicable to the ST quantities. The conditions of exposure and firing for
fuzes are the same as those for projectiles as described in MTP 4-2-504.
Following are the minimum quantities required by MTP 4-2-504 for safety
testing:
Metal parts checkout
Storage
Vibration (at extreme temperatures)
Sequential rough handling (at extreme
temperatures)
Worn tube effect (if applicable)

NOTE:

The above sample sizes are for a fuze used with a


specific projectile in a specific weapon system.
When a fuze is designed to be used in many systems,
the quantities will be increased based on engineering
judgment.
The economy involved may require the elimination of testing with similar systems that would
produce no differences in the effect on safety.

and firing.
6.2.3

Functioning and Operational Tests

Fuzes designed to function by impact, time, or proximity will


undergo appropriate conditioning, dynamic firing, and other tests to determine
whether they operate and function according to design requirements under all
environments specified.
Guidance for number of samples, test procedures, and
analysis of test results is contained in the appropriate MTP's.
The smaple size and test plan for determining range accuracy
(MTP 3-1-004) will be coordinated with personnel responsible for firing table
data.
Functioning reliability will be computed with enough samples to provide the reliability at the confidence intervals necessary to determine compliance with the specifications (MTP 3-1-002).
Data from the safety evaluation
(paragraph 6.2.1) may be used as applicable to increase sample size for reliability considerations.
The following tests will be conducted when applicable:

-10-

6.2.3.1

Impact Fuzes

a.
Impact Sensitivity - Impact sensitivity is determined by
firing against targets offering a varying degree of orientation and resistance to the fuzes. Many fuzes are designed to be activated by targets
with little
resistance.
They are not, however, to be prematurely activated
by conditions, natural or induced, thay may be encountered in the flight of
the fuze to the target.
Conduct test as described in MTP 4-2-806.
b.
Terminal Effects - These effects are determined in conjunction
with tests of the fuzed projectile.
The important characteristics in these
tests are target or range dispersion, lethal effects, and reliability.
Conduct testing in accordance with appliacable sections of the following MTP's:

Vertical Target Accuracy and Dispersion.

c.
Extreme Conditions - Safety and performance of a fuze under
extreme environments, including transportation and handling, are determined
by tests specified in paragraphs 6.2.1 and 6.2.2.
d.
Arming Tests - Fuzes are usually designed to be boresafe by
inclusion of a delay arming feature in the fuze (safety adapter or booster
assembly).
Test procedures to determine the safe arming and nonarming distances are based on a statistical procedure for varying the target distances
(MTP's 3-1-002, 4-2-806).
Engineering tests may consist simply of verifying
the positive arming and nonarming distances established during EDT.
6.2.3.2

Time Fuzes

a.
Impact Sensitivity - (Same as for impact fuzes, paragraph
above).
b.
Time to Burst and Functioning reliability - Timing of the
interval between launching and functioning in flight is required.
This is
accomplished be means of fuze chronographs backed up by stop watches, by
telemetry methods when feasible, or by modifying the fuze to emit signals.
Test firings will cover a combination of variables to include the following:
6.2.3.1a,

1)

2)
3)

Weapons:
Of the weapons that will employ the test fuze
in their projectiles, those weapons producing the maximum
and minimum interior ballistic values must be used in the
test, plus others that may be desirable.
Charge zones: Minimum and maximum charge zones for each
weapon will be used.
Fuze settings: Three fuze settings are usually desirable
near maximum, near minimum, and intermediate, though
some test at absolute maximum and absolute minimum may
be desirable.

-11-

MTP 4-2-055

Test temperatures:
Tests at -50F and 145F should
provide adequate coverage.

The exact number of rounds to fire under each condition will


depend upon the reliability requirements of the SDR or QMR, and the amount
of usable data acquired from other portions of the fuze test. As a rule,
under one combination of conditions, no less than 10 rounds are fired.
Conduct test as described in applicable sections of MTP's 2-1-004, 3-2-825,
4-2-807, and 4-2-808.

6.2.3.3

Proximity Fuzes

a.
Arming Tests - The arming devices for proximity fuzes are
usually tested as separate units in special carriers that detonate to give
signals for recording arming time or distance.
This is called functioning
on arming.
The use of telemetry (MTP 2-1-004) may also be desirable for
certain types of fuzes.
Conduct test as described in applicable sections of
MTP's 3-2-615, 3-2-825, and 6-2-508.
b.
Functioning Location and Reliability - Points of impact or
burst are located with visual or photographic equipment depending upon the
nature of the test.
Variables to evaluate are weapons, ranges, zone charges,
and temperatures (-50*F and 145*F).
Rounds to fire under a set of conditions
are dependent upon the reliability requirements of the QMR or SDR and upon
other usable data available.
Conduct test as described in applicable sections

IMPACT,

TIME, AND PROXIMITY FUZES

IMPACT FUZE

Impact fuzes are usually attached to either the base or nose of the projectile and referred to as base detonating (BD) or point detonating (PD)
fuzes, respectively, or they may be attached in part to both ends of the
projectile and referred to as point initiating, base detonating (PIBD) fuzes.
They contain a device to activate functioning as a result of projectile impact against a target.
BD impact fuzes are usually employed in direct fire
against "hard" targets, whereas PD fuzes are employed in indirect fire against
"soft" targets.
An impact fuze may be either delay, nondelay, or superquick,
depending upon the time interval from target contact to completion of its
function.
2.

TIME FUZE

Time fuzes are usually attached to the nose end of a projectile and contain a device, mechanical (MT) or electrical (ET), activated as a result of
a predetermined time selected and fixed into the device prior to launching.
They are calibrated in seconds, or, in some cases, the time scale has been
converted to "range" in meters.
Time fuzes are employed when projectile
functioning is required throughout a range of time and sensing for activation
of a device that cannot be accomplished by means of impact or proximith fuzes.
Time fuzes are most widely used in indirect fire where projectile functioning
is required at a considerable height above the target.
3.

PROXIMITY FUZE

Proximity fuzes are usually assembled to the nose end of a projectile.


They contain a device for emitting an electronic impulse at a selected or
predetermined time after launching.
When this impulse is reflected back to
the fuze, for a distance predetermined and built into the fuze, the fuze
functioning is initiated.
The fuzes also usually have an impact device as
a secondary initiating feature.
These fuzes are used primarily for indirect
fire where projectile functioning is required near the target and greater
precision in distance from the target is required than is offered by the present preset time fuze.
The proximity fuze may have a requirement for use
against aircraft and may also contain a self-destruct feature.
