Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the international Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 8669-2 was prepared by Technical Committee
ISOITC 173, Technical systems and aids for disabled or handicapped
persons, Subcommittee SC 3, Aids for ostomy and incontinence.
This second edition cancels and replaces the first editions of
IS0 8669-2:1988, IS0 8669-3:1990 and IS0 8669-4:1990, which have
been technically revised.
IS0 8669 consists of the following parts, under the general title Urine
collection bags:
- Part I: Vocabulary
- Part 2: Requirements and test methods
Annex A forms an integral part of this part of IS0 8669.

Introduction
Users of this part of IS0 8669 are advised to consider the desirability of
third-party certification of product conformity with this part of IS0 8669,
based on testing and continuing surveillance, which may be coupled with
assessment of a supplier ’s quality system against the appropriate
standards in the IS0 9000 series.

IS0 8669-2: 1996(E)
@ IS0
5.2 Test samples
Testing shall be carried out on product samples as supplied to the end user.
6 Test methods
6.1 Test volume
6.1 .l Principle
The urine collection bag is filled with water and the volume of water within the bag is measured.
6.1.2 Reagent
6.1.2.1 Tap water
6.1.3 Apparatus
Graduated cylinders, of capacities to suit the bags being tested and having a measurement accuracy of
6.1.3.1
+ - 2 %.
6.1.3.2 Filling system, of arrangement and dimensions shown in figure 1.
To maintain a constant hydrostatic head, the rate of flow into the reservoir of the fillling system shall be higher than
the rate of the filling of the bag.
6.1.3.3 Stopwatch, or similar timing device.
6.1.4 Procedure
6.1.4.1 Cut the inlet tubing so that the reservoir tap is positioned as close as possible to the bag.
NOTE - For bags having extensible tubing, these should be drawn out to their maximum length before cutting.
6.1.4.2 Remove as much air as possible from the bag. Close the drainage tap afterwards.
Most bags have a drainage tap through which air can be squeezed out.
NOTE -
6.1.4.3 Measure the distance between bottom and top of the bag (Z4 in figure A.l) and mark a horizontal line at
0,75 14, measuring from the bottom of the bag.

ody-worn bag fre ely in a vertical position , so that the volume of the bag is not restricted.
b
6.1.4.5 Using the filling system (6.1.3.2), ensure that the reservoir tap is closed, turn on the water supply (6.1.2.1)
and adjust the hydrostatic head to 500 mm + 5 mm. Connect the reservoir tap to the inlet tubing of the bag.
6.1.4.6 Open the reservoir tap and allow water to enter the bag, ensuring that no air is entrained.
6.1.4.7 When the water level inside the bag has risen to the 0,75 Z4 line, start the stopwatch (6.1.3.3).
6.1.4.8 After 1 min but before 1 min 10 s, close the reservoir tap.
6.1.4.9 Visually inspect the bag to determine whether or not leakage has occurred. If leakage has occurred, deem
the test invalid and repeat it, using a fresh bag if necessary.
6.1.4.10 Clamp the inlet tubing as close to the filling top surface of the bag as possible. Remove the bag from the
filling system and empty the water from the bag into a graduated cylinder (6.1.3.1). Measure the volume, in
millilitres, and record it as the test volume to an accuracy of + 2 %.
IS0 8669-2: 1996(E)

6.2.4 Procedure
6.2.4.1 Suspend a non-body-worn bag using the manufacturer ’s recommended suspension system. Suspend a
body-worn bag freely, so that the volume of the bag is not restricted.
6.2.4.2 If the bag is fitted with a drainage tap, add a small volume of the water (6.2.2.1) into the bag, open the
drainage tap and allow the bag to drain, and then fully open and close the drainage tap ten times. Empty the bag
and close the tap.

IS0 8669-2: 1996(E)
Using the graduated cylinder and the filling system in figure 2 with a distance of 500 mm + 5 mm between
6.2.4.3
the top of the bag and the bottom of the reservoir, add to the bag a volume of coloured water (622.2) equal to 75 %
of the test volume (6.1.4.10), ensuring that no air is entrained.
6.2.4.4 Seal the inlet tubing and, if present, the air vent.
6.2.4.5 Place the absorbent material (6.2.2.3) on a flat surface. Remove the bag from the suspension system and
place it horizontally on the absorbent material.
6.2.4.6 Leave the bag undisturbed for 17 h + 1 h and then visually inspect the bag and absorbent material for
staining caused by leakage. If staining is observed, the urine collection bag under test is deemed to have failed.
6.2.4.7 Reposition the bag under test in a vertical position, as described in 6.2.4.1, above absorbent material.
6.2.4.8 Leave the bag undisturbed for 4 h & 1 h, then visually inspect the bag and absorbent material for staining
caused by leakage. If staining is observed, the urine collection bag under test is deemed to have failed.
6.2.5 Test report
The test report shall contain the general information specified in clause 7, together with a statement as to whether
or not leakage was observed and, if so, from where the leakage occurred and at which orientation of the bag.
6.3 Freedom from leakage under load
6.3.1 Principle
Coloured water is added to the uring collection bag under test, which is then subjected to a compressive load
between two parallel plates. The bag is then visually inspected for leakage.
6.3.2 Reagent
6.3.2.1 Coloured water, as specified in 6.2.2.2.
6.3.2.2 Absorbent material, white.
6.3.3 Apparatus
