4 Requirements, classifications and test conditions
4.1 General
After being completely tested according to section 6 in this standard, the following requirements shall be
fulfilled:
a) No perforation as defined in section 6.13 shall be detected.
b) The indentation depths in the backing material after each shot shall be less than the maximum allowed
indentation depth as defined in section 4.2.
c) No ricochet shall be observed, as described in section 6.13.
d) No bullet shall be observed slipping outside the specimen from the side, as described in section 6.13.
e) If a rigid panel is incorporated in the design, no part of that panel, i.e. pieces of metal or ceramic plate,
shall be found in the backing material.
Bullet resistant body armour shall also meet the requirements described in Part 1 of this standard.

NOTE Compliance with Parts 1 and 2 of the Standard does not imply that the body armour provides stab protection.
Compliance with Parts 1 and 3 of this standard is necessary for stab protection. For dual-purpose body armour i.e. Ballistic
+ Stab, compliance with Parts 1, 2 and 3 is required.
4.2 Permitted indentation depth in backing material
For any shot, the indentation in the backing material shall not exceed 22 mm + the average deformation value
determined during the backing material plasticity calibration.
NOTE Since the maximum allowed spread in the plasticity calibration value is 20 ± 2 mm, the actual limit in
indentation value will vary between 40 and 44 mm depending on the actual plasticity of the backing material.
4.3 Test ammunition to be used for different protection levels
When testing a body armour according to this document, depending on the protection class, ammunition,
shooting distance and impact velocity according to the following specification shall be used.

NOTE 1 The use of particular reference bullets implies a full specification of the bullets (e.g. DAG DM41 fully defines a
particular bullet).
NOTE 2 Information on how to measure the distance can be found in section 6.8.
NOTE 3 The distance is picked only to allow for the bullet to stabilise in the air, and the accuracy shall allow for testing on
curved specimens without moving the target between shots. The important parameter for defining the impact energy, is the
impact velocity in the table above. The retardation of the bullet over a distance of one meter (the accuracy of the distance) is
not considered significant.

4.4 Test conditions and Test Specimen/samples
If protection in levels G2, G3 and G4 is achieved by adding extra insert plates onto a combination of carrier
and body armour with basic protection, then:
a) the tests for those classes shall be made with the insert plats mounted on the carrier/basic body armour;
b) the carrier/basic body armour itself shall pass a full test for protection class G1.
4.5 Number of test shots to make for different protection levels and features
4.5.1 Basic tests
4.5.1.1 Regular basic test
When testing a Body Armour according to this document, depending on the protection class and the type of
test to be performed, the following number of shots shall be made.

NOTE The table lists the number of test shots per bullet type. For some protection classes test shots might be prescribed with
more than one bullet type, and the number of total shots will then increase.

If a body armour shall offer both bullet resistance as well as stab resistance simultaneously, a non-detachable
construction shall be subjected to both a ballistic test according to this document and a stab test according to
part 3 of this standard.
The ballistic tests and the stab tests are performed on different test specimens.
If another shooting angle than 25° could be expected to be more severe for the body armour, then that angle
should be tested with three additional shots at +20 °C.
4.5.1.2 Shatter gap test
For each bullet tested, an additional test shall be made with six shots at +20 °C and a bullet velocity 100 m/s
slower than the nominal bullet velocity for that bullet
4.5.1.3 Edge test
For body armour tested to level G1 an additional impact (edge impact) shall be shot at a distance to the edge
of the specimen of 30 ± 5 mm and at least 75 mm from the corner.
NOTE As described in 6.10, the indentation depth in the backing material is not measured for this shot.

If a body armour, that has passed the tests according to this document, can be equipped with an add-on
knife/spike stab resistant part, the body armour shall be subject to additional ballistic tests according to table 3
with the knife/stab protection mounted on the garment. The additional ballistic tests are performed on different
specimens.

will require additional test samples.

If, during testing or test preparations, a potential deficiency or weakness is noted, which will not be detected
by testing according to the shooting patterns prescribed in this standard then the product should be subjected
to further testing in the potential weak or deficient areas using test conditions according to this standard.
This is particularly valid for body armour with overlapping design or body armour consisting of adjacent plates.
Overlapping design is tested with 3 shots with 25° angle of impact, adjacent plates are tested with 3 shots with
0° angle of impact.
5 Test equipment and test resources
5.1 Test set up
Test set up shall be according to Annex A of this standard.
5.2 Precision of test equipment
Precision of test equipment shall be as follows:

 Temperature measurement: ± 0,5 °C;
 Measurement of humidity: ± 1 % relative humidity;
 Measurement of linear dimensions: ± 1 % of measured value;
 Measurement of angular dimensions: ± 0,5°;
 Measurement of masses: 1 ‰ of measured value.
5.3 Backing material
5.3.1 General
To mount the test specimens and measure the indentation depth modelling clay shall be used. This shall be
placed into a box with inside dimensions of 350 mm x 400 mm x 150 mm, with one side open (350 x 400 mm),
so that it is filled completely to the edges, air locks are to be avoided. Before the plasticity calibration test, the
modelling clay is to be treated to approximately 30 blows evenly distributed over the surface (e.g. with a
wooden mallet) and the surface is then to be scraped level with a heavy knife.
1)
NOTE Suitable plastelina can be sourced from Fa. Carl Weible KG, PO box 1648, 73606 Schorndorf Plasticity
Calibration Test
The box with the backing material is placed flat on the floor with the modelling clay facing upwards. This floor
shall be firm enough to hold the box and show no deformation during the plasticity calibration tests of the
backing material. The backing material is calibrated by drop tests with a steel ball. The modelling clay should
be hit 5 times by a steel ball of 1039 ± 5 g (diameter 63,5 ± 0,05 mm) which is dropped from a height of
2000 ± 5 mm. The drop height is measured from the bottom of the steel ball to the top of the backing. The flat
surface or the tangential level to the surface of the backing material at the point of impact of the ball shall be
horizontal with a precision of 5 mm on 1 m. The centre of a drop shall be at least 80 mm from the side of the
modelling clay and at least 140 mm from earlier drops. After each drop the surface of the backing material
should be flattened by cutting the parts which are outside the box using a knife and the depth of the
indentation shall be measured (the distance from the surface of the backing to the deepest point of
indentation). The depth of the indentations shall be measured with an accuracy of ± 0,5 mm. The
indentations should be filled only after all 5 drop tests have been completed.
The backing material is accepted for use in the tests if the average indentation depth is 20 ± 2 mm and all
indentation depths are within 20 ± 2 mm.
The temperature of the plastelina during test shall be 25 ± 10 °C.
NOTE Temperature affects the plasticity of the modelling clay, and is varied to control the plasticity into the
prescribed interval.
The test report shall contain the average of 5 steel ball drops, conducted just before the test series start.

CEN/TC 162 of the product named. Equivalent products may be used if they can be shown to lead to the same results.
