33、onal Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been
34、 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. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standa
35、rdization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for
36、voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all
37、such patent rights. ISO 11140-3 was prepared by Technical Committee ISO/TC 198, Sterilization of health care products. This second edition cancels and replaces the first edition (ISO 11140-3:2000) which has been technically revised. ISO 11140 consists of the following parts, under the general title
38、Sterilization of health care products Chemical indicators: Part 1: General requirements Part 3: Class 2 indicator systems for use in the Bowie and Dick-type steam penetration test Part 4: Class 2 indicators as an alternative to the Bowie and Dick-type test for detection of steam penetration Part 5:

40、 sterilizers for wrapped goods and porous loads. As such it is performed during the demonstration of conformance of steam sterilizers to EN 285 and as a routine test of performance in ISO 17665-1. The test method is described in EN 285. A failure of the Bowie and Dick test is symptomatic of a number
41、 of potential problems with the sterilizer that could compromise the uniform sterilization of a load to be processed. This failure is not conclusive proof that the fault in the sterilizer is due to air retention, air leakage or non-condensable gases and it can be necessary to investigate other cause
42、s of failure. The Bowie and Dick test was conceived as a test for successful air removal from high-vacuum porous-load sterilizers used in the sterilization of health care products 1. A successful Bowie and Dick test indicates rapid and even penetration of steam into the test pack. The presence of ai
43、r within the pack, due to an inefficient air removal stage, an air leak during this stage or non-condensable gases in the steam supply, is a circumstance which can lead to failure of the test. The result of the test may also be affected by other factors which inhibit steam penetration. The test does
44、 not necessarily demonstrate either achievement of the required temperature or maintenance of that temperature for the required time to achieve sterilization. A test pack for the Bowie and Dick test consists of two components: a) a small standardized test load; b) a chemical indicator to detect the
45、presence of steam. The Bowie and Dick test as originally described 1utilized huckaback towels as the material for the test load. The test as described in EN 285 uses cotton sheets for this purpose. Because a range of different tests in different countries has historically been termed the Bowie and D
46、ick test, the term “Bowie and Dick-type test” is used in this part of ISO 11140.

48、nts for chemical indicators to be used in the steam penetration test for steam sterilizers for wrapped goods, e.g. instruments and porous materials. The indicator for this purpose is a Class 2 indicator as described in ISO 11140-1. Indicators complying with this part of ISO 11140 are intended for us
49、e in combination with the standard test pack as described in EN 285. This part of ISO 11140 does not consider the performance of the standard test pack, but does specify the performance of the indicator systems. 2 Normative references The following referenced documents are indispensable for the application of this document.
