20、rganization 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 estab
21、lished 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 Intemational Electrotechnical Commission (IEC) on all matters of electrotechnical standardizati
22、on. 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 8670-2 was prepared by Technical Committee
23、 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 gener
24、al title Ostomy collections bags: - Part 7: Vocabulary - Part 2: Requirements and test methods iii EN IS0 8670-2 : 1996 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
25、 and continuing surveillance, which may be coupled with assessment of a suppliers quality system against the appropriate standards in the IS0 9000 series. iv STD-BSI BS EN IS0 Bb70-2-ENGL 1997 Lb2qbbS ObLbb00 252 EN IS0 8670-2 : 1996 Ostomy collection bags - Part 2: Requirements and test methods 1 S

32、 bags without flanges shall not leak. 4.1.2 When tested by the method given in 6.3, bags (systems) with 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
33、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 suppl
34、ier. 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 OC f 2 OC. 5.2 Test sa
35、mples Testing shall be carried out on product samples as supplied to the end-user. 6 Test methods 6.1 Test volume 6.1.1 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. 2 STD-BSI BS EN IS0 Bb70-2-ENGL 1997 L
36、bZqbbS ObLbbOZ 025 EN IS0 8670-2 : 1996 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 f 0,2 mm to which a connector fitted with a tap can be secured. 6.1.3.2 Means of fill
37、ing 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 f 2 %.

38、e 6.1.4 Procedure 6.1.4.1 For open-ended bags with a bottom opening, close the outlet 30 mm k 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 accordan
39、ce with the manufacturers instructions. Do not use a rubber band for closure purposes. 3 STD-BSI BS EN IS0 Bb70-2-ENGL 1777 Lb2Ybb7 Ob1bb03 TbL EN IS0 8670-2 : 1996 6.1.4.2 If there is no precut opening in the ostomy bag assembly, or if the opening is of diameter less thai 15 mm, cut a central hole
40、of diameter 15 mm +: 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. 6.1.4.4 Remove as much a
41、ir as possible from the ostomy bag under test. In the case of urostomy bags, this may mean opening the drainage tap while pressing against the bag, and then closing the drainage tap. Insert the filling connector (6.1.3.2) into the test plate with the tap in the closed position. 6.1.4.5 Open the wate
42、r supply tap (6.1.2.1) and allow water to enter the bag, ensuring that no air is entrained, until the level of water in the bag reaches the bottom of the hole in the test plate. Turn off the tap. 6.1.4.6 Remove the filling connector from the test plate and allow the level of water in the bag to stab
43、ilize for 1 min+: s. 6.1.4.7 If necessary, remove or add water to the bag using the filling connector until the water in the bag is level with the bottom of the hole in the test plate when filling connector is removed. NOTE - In the case of urostomy bags, two water levels may be observed, one on eac
44、h side of the nonretum valve. In this case, the upper water level at the fiange opening is used to establish the test volume. 6.1.4.8 Empty the water from the bag into a graduated cylinder (6.1.3.3). Measure the volume, in millilitres, and record it as the test volume of the bag. 6.1.5 Test report T
45、he test report shall contain the general information specified in clause 7, together with the test volume. 6.2 Freedom from leakage of bags without flanges 6.2.1 Principle The ostomy collection bag is filled with coloured water, positioned horizontally and examined for leakage. It is then suspended
46、vertically and again examined visually for leakage. This method does not test for: a) leakage from vents, filters, vent and filter plugs and the interface between the test surface and the bag assembly; b) leakage from the open-ended bag closure. 6.2.2 Reagent 6.2.2.1 Coloured water, comprising tap w

48、670-2 : 1996 6.2.4 Procedure 6.2.4.1 Seal all openings (see 6.2.3.2), such as vents, filters and openings of open-ended bags, and attach the bag to the test plate (6.1.3.1). If there is no precut opening for the stoma, cut a hole as described in 6.1.4.2. Attach the bag to the test plate as described
49、 in 6.1.4.3. 6.2.4.2 If the bag is a urostomy bag fitted with a drainage tap, pour a small amount of coloured water (6.2.2.1) into the bag and open and close the tap ten times, ensuring that the coloured water is present in the bag during the whole operation. 6.2.4.3 Position the baghest plate assembly vertically and fill the bag through the filling port with 75 % of the test volume (see 6.1.4.8) using the coloured water, ensuring that air is not entrained. 6.2.4.4 Visually inspect the bag for leakage after 1
