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 8670-Z was prepared by Technical Committee
ISO/TC 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 edition
(IS0 8670-2:1991) which has been technically revised.
IS0 8670 consists of the following parts, under the general title Ostomy
collections bags:

- Pat? 2: Requirements and test methods

Introduction
Users of this part of IS0 8670 are advised to consider the desirability of
third-party certification of product conformity with this part of IS0 8670,
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 8670-l :1996, Ostomy collection bags - Part 1: Vocabulary.
3 Definitions
For the purposes of this part of IS0 8670, the definitions given in IS0 8670-l and the following definitions apply.
3.1 flatus filter: Device that contains a porous material for deodorizing flatus as it escapes from the bag.
3.2 multiple-piece flange system: Effluent collection system in which a component is positioned around the
stoma allowing an effluent collection bag to be attached or removed while the component itself remains in position.
3.3 ostomy bag: Flexible container for collecting body effluent from the stoma.
3.4 stoma: Abnormal opening established on the body surface.
3.5 test volume: That volume on which is based the volume of liquid added, or the force applied, to an ostomy
collection bag when performing tests to verify the strength and leakage resistance of the bag assembly.

IS0 8670-2: 1996(E)
4 Requirements
4.1 Freedom from leakage
4.1.1 When tested by the method given in 6.2, bags without flanges shall not leak.

4.2 Retention of open-ended bag closure
When tested by the method given in 6.4, the open-ended bag closure shall remain in position when used following
the bag manufacturer’s instructions.
4.3 Burst strength (static)
When tested by the method given in 6.5, the bag shall not leak.
4.4 Marking of the ostomy collection system
4.4.1 For identification purposes, the bag shall be marked with at least the product code and the name and/or
trademark of the manufacturer or supplier.
4.4.2 If the opening for the stoma is intended to be enlarged, the maximum opening shall be either
a) marked on the product
or
b) given in the instructions.
5 General test conditions
5.1 Temperature
The standard temperature for testing (atmosphere and reagent) shall be 23 “C + 2 “C.
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 ostomy 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.
0 IS0 IS0 8670-2: 1996(E)
6.1.3 Apparatus
6.1.3.1 Rigid transparent plate (see figure l), of sufficient size to support the whole of the bag in the horizontal
position, having a hole of diameter 10 mm IfI 0,2 mm to which a connector fitted with a tap can be secured.
6.1.3.2 Means of filling the bag, from the tap or reservoir, ensuring that air is not entrained.
6.1.3.3 Graduated cylinders, of capacities to suit the bags being tested and having a measurement accuracy of
+ 2 Oh.

6.1.4 Procedure
6.1.4.1 For open-ended bags with a bottom opening, close the outlet 30 mm + 5 mm from the bottom by welding
or by repeated folding secured with a binder clip or other securing device not exceeding 100 g in mass. For open-
ended bags with a top opening, close the opening in accordance with the manufacturer’s instructions.
Do not use a rubber band for closure purposes.

6.1.4.2 If there is no precut opening in the ostomy bag assembly, or if the opening is of diameter less than
15 mm, cut a central hole of diameter 15 mm ‘g mm.
6.1.4.3 With the rigid transparent test plate (6.1.3.1) in a vertical position, attach the ostomy bag assembly so the
bag opening is concentric with the hole in the test plate. Ensure that the bag is positioned so that its movement is
not restricted.
Remove as much air as possible from the ostomy bag under test. In the case of urostomy bags, this may
6.1.4.4
mean opening the drainage tap while pressing against the bag, and then closing the drainage tap.
