National foreword
This revision of this Part of BS 4826 has been prepared under the direction of the
Packaging and Freight Containers Standards Committee and is identical with
ISO 2248-1985 “Packaging — Complete, filled transport packages — Vertical
impact test by dropping” published by the International Organization for
Standardization (ISO). It supersedes BS 4826-4:1972 which is withdrawn.
In 1992 the European Committee for Standardization (CEN) accepted
ISO 2248-1985 as European Standard EN 22248:1992. As a consequence of
implementing the European Standard this British Standard is renumbered as
BS EN 22248 and any reference to BS 4826-4 should be read as a reference to
BS EN 22248.
Terminology and conventions. The text of the international standard has
been approved as suitable for publication as a British Standard without
deviation. Some terminology and certain conventions are not identical with those
used in British Standards; attention is drawn especially to the following.
The comma has been used as a decimal marker. In British Standards it is current
practice to use a full point on the baseline as the decimal marker.
Wherever the words “International Standard” appear, referring to this standard,
they should be read as “British Standard”.
The Technical Committee has reviewed the provisions of ISO 2233, a new edition
of which is currently in preparation and to which reference is made in the text,
and has decided that they are acceptable for use in conjunction with this
standard.
A related British Standard is BS 4826 “Complete, filled transport packages”
Part 2:1986 “Method of conditioning for testing”.
A British Standard does not purport to include all the necessary provisions of a
contract. Users of British Standards are responsible for their correct application.
Compliance with a British Standard does not of itself confer immunity
from legal obligations.

1 Scope and field of application
This International Standard specifies a method for
carrying out a vertical impact test on a complete,
filled transport package by dropping. It may be
performed either as a single test to investigate the
effects of vertical impact or as part of a sequence of
tests designed to measure the ability of a package to
withstand a distribution system that includes a
vertical impact hazard.
2 References
ISO 2206, Packaging — Complete, filled transport
packages — Identification of parts when testing.
ISO 2233, Packaging — Complete, filled transport
packages — Conditioning for testing.
3 Principle
Raising of the test package above a rigid plane
surface and releasing it to strike this surface
(the “impact surface”) after a free fall 1). The
atmospheric conditions, the height of drop and the
attitude of the package are predetermined.
4 Apparatus
4.1 Lifting arrangement, which will not damage the
test package during either lifting or release.
4.2 Means of holding the test package prior to
release in its predetermined attitude.2)
4.3 Release mechanism, to release the test package
in such a way that its fall is not obstructed by any
part of the apparatus before striking the impact
surface (4.4).
4.4 Impact surface, horizontal and flat, massive
enough to be immovable and rigid enough to be
non-deformable under test conditions.
NOTE In normal circumstances, the impact surface provided
shall be
— integral with a mass at least 50 times that of the heaviest
package to be tested;
— flat, such that no two points on its surface differ in level by
more than 2 mm;
— rigid, such that it will not be deformed by more
than 0,1 mm when an area of 100 mm2 is loaded statically
with 10 kg anywhere on the surface;
— sufficiently large to ensure that the test package falls
entirely upon the surface.
In addition, the apparatus shall meet the
requirements and tolerances of clause 7.
5 Package preparation
The test package shall normally be filled with its
intended contents. However, simulated or dummy
contents may be used, on condition that the
dimensions and physical properties of such contents
shall be as close as possible to those of the intended
contents.
Ensure that the test package is closed normally, as
if ready for distribution. If simulated or dummy
contents are used, ensure that the normal method of
closure is still employed.
6 Conditioning
The package shall be conditioned in accordance with
one of the conditions described in ISO 2233.
7 Procedure
Whenever possible the test shall be carried out in
the same atmospheric conditions as used for
conditioning, where this is critical to the materials
or application of the package. In other
circumstances, the test shall be carried out in
atmospheric conditions which are as near as
practicable to those used for conditioning.
7.1 Lift the test package and hold it in the
predetermined attitude (see annex) at a height
within ± 2 % of the predetermined drop height as
defined by the distance between the lowest point on
the package at the time of release and the nearest
point on the impact surface (4.4).
7.2 Release the test package from its predetermined
attitude within the following tolerances:
— for face or edge drops: 2° maximum angle
between the impacting face, or edge, and the
horizontal surface;
— for edge or corner drops: the angle between a
prescribed surface of the package and the
horizontal surface ± 5° or ± 10 % of the angle,
whichever is the greater.
The velocity at impact shall be within ± 1 % of that
which would be achieved by a free fall.
1) In some circumstances, a completely free fall may not be possible; in such circumstances, the impact velocity shall be
within 1 % of that which is achieved by a free fall.
2) The difference in behaviour of a sack, for example, suspended from the top or supported below in an end drop, could be
significant. In such instances, the method of holding the package before dropping shall be described in the test report.

8 Test report
The test report shall include the following
particulars:
a) reference to this International Standard;
b) number of replicate packages tested;
c) full description of the package, including
dimensions, structural and material
specifications of the package and its fittings,
cushioning, blocking, closure or reinforcing

e) gross mass of package and mass of contents, in
kilograms;
f) relative humidity, temperature and time of
conditioning, temperature and relative humidity
of test area at time of test; whether these values
comply with the requirements of ISO 2233;
g) the attitude in which the package was tested,
stated in one of the ways given in the annex;
h) drop height, in millimetres;
j) type of apparatus;
k) any deviations from the test method described
in this International Standard;
