1、ANSI/AAMI/ISO 11140-1:2014Sterilization of health care productsChemical indicatorsPart 1: General requirementsAmerican National StandardObjectives and uses of AAMI standards and recommended practices It is most important that the objectives and potential uses of an AAMI product standard or recommend

2、ed practice are clearly understood. The objectives of AAMIs technical development program derive from AAMIs overall mission: the advancement of medical instrumentation. Essential to such advancement are (1) a continued increase in the safe and effective application of current technologies to patient

3、 care, and (2) the encouragement of new technologies. It is AAMIs view that standards and recommended practices can contribute significantly to the advancement of medical instrumentation, provided that they are drafted with attention to these objectives and provided that arbitrary and restrictive us

4、es are avoided. A voluntary standard for a medical device recommends to the manufacturer the information that should be provided with or on the product, basic safety and performance criteria that should be considered in qualifying the device for clinical use, and the measurement techniques that can

5、be used to determine whether the device conforms with the safety and performance criteria and/or to compare the performance characteristics of different products. Some standards emphasize the information that should be provided with the device, including performance characteristics, instructions for

6、 use, warnings and precautions, and other data considered important in ensuring the safe and effective use of the device in the clinical environment. Recommending the disclosure of performance characteristics often necessitates the development of specialized test methods to facilitate uniformity in

7、reporting; reaching consensus on these tests can represent a considerable part of committee work. When a drafting committee determines that clinical concerns warrant the establishment of minimum safety and performance criteria, referee tests must be provided and the reasons for establishing the crit

8、eria must be documented in the rationale. A recommended practice provides guidelines for the use, care, and/or processing of a medical device or system. A recommended practice does not address device performance per se, but rather procedures and practices that will help ensure that a device is used

9、safely and effectively and that its performance will be maintained. Although a device standard is primarily directed to the manufacturer, it may also be of value to the potential purchaser or user of the device as a frame of reference for device evaluation. Similarly, even though a recommended pract

10、ice is usually oriented towards healthcare professionals, it may be useful to the manufacturer in better understanding the environment in which a medical device will be used. Also, some recommended practices, while not addressing device performance criteria, provide guidelines to industrial personne

11、l on such subjects as sterilization processing, methods of collecting data to establish safety and efficacy, human engineering, and other processing or evaluation techniques; such guidelines may be useful to health care professionals in understanding industrial practices. In determining whether an A

12、AMI standard or recommended practice is relevant to the specific needs of a potential user of the document, several important concepts must be recognized: All AAMI standards and recommended practices are voluntary (unless, of course, they are adopted by government regulatory or procurement authoriti

13、es). The application of a standard or recommended practice is solely within the discretion and professional judgment of the user of the document. Each AAMI standard or recommended practice reflects the collective expertise of a committee of health care professionals and industrial representatives, w

14、hose work has been reviewed nationally (and sometimes internationally). As such, the consensus recommendations embodied in a standard or recommended practice are intended to respond to clinical needs and, ultimately, to help ensure patient safety. A standard or recommended practice is limited, howev

15、er, in the sense that it responds generally to perceived risks and conditions that may not always be relevant to specific situations. A standard or recommended practice is an important reference in responsible decision-making, but it should never replace responsible decision-making. Despite periodic

16、 review and revision (at least once every five years), a standard or recommended practice is necessarily a static document applied to a dynamic technology. Therefore, a standards user must carefully review the reasons why the document was initially developed and the specific rationale for each of it

17、s provisions. This review will reveal whether the document remains relevant to the specific needs of the user. Particular care should be taken in applying a product standard to existing devices and equipment, and in applying a recommended practice to current procedures and practices. While observed

18、or potential risks with existing equipment typically form the basis for the safety and performance criteria defined in a standard, professional judgment must be used in applying these criteria to existing equipment. No single source of information will serve to identify a particular product as “unsa

19、fe“. A voluntary standard can be used as one resource, but the ultimate decision as to product safety and efficacy must take into account the specifics of its utilization and, of course, cost-benefit considerations. Similarly, a recommended practice should be analyzed in the context of the specific

20、needs and resources of the individual institution or firm. Again, the rationale accompanying each AAMI standard and recommended practice is an excellent guide to the reasoning and data underlying its provision. In summary, a standard or recommended practice is truly useful only when it is used in co

21、njunction with other sources of information and policy guidance and in the context of professional experience and judgment. INTERPRETATIONS OF AAMI STANDARDS AND RECOMMENDED PRACTICES Requests for interpretations of AAMI standards and recommended practices must be made in writing, to the AAMI Vice P

22、resident, Standards Policy and Programs. An official interpretation must be approved by letter ballot of the originating committee and subsequently reviewed and approved by the AAMI Standards Board. The interpretation will become official and representation of the Association only upon exhaustion of

23、 any appeals and upon publication of notice of interpretation in the “Standards Monitor“ section of the AAMI News. The Association for the Advancement of Medical Instrumentation disclaims responsibility for any characterization or explanation of a standard or recommended practice which has not been

24、developed and communicated in accordance with this procedure and which is not published, by appropriate notice, as an official interpretation in the AAMI News.

The existence of an AAMI standard does not in any respect preclude anyone, whether they have approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard. AAMI standards are subject t

28、o periodic review, and users are cautioned to obtain the latest editions. CAUTION NOTICE: This AAMI standard may be revised or withdrawn at any time. AAMI procedures require that action be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of publication. Int

41、ancement of Medical Instrumentation Chemical Indicators Working Group The adoption of ISO 11140-1:2014 as an American National Standard was initiated by the AAMI Chemical Indicators Working Group of the AAMI Sterilization Standards Committee. The AAMI Chemical Indicators Working Group also functions

42、 as a U.S. Technical Advisory Group to the relevant work in the International Organization for Sterilization (ISO). U.S. representatives from the AAMI Chemical Indicators Working Group (U.S. Sub-TAG for ISO/TC 198/WG 6, Chemical indicators) played an active part in developing the ISO standard. At th

43、e time this document was published, the AAMI Chemical Indicators Working Group had the following members: Chair: Richard Bancroft Kristen Singleton, PhD Members: Richard Bancroft, STERIS Corp.

The concepts incorporated in this standard should not be considered inflexible or static. This standard, like any other, must be reviewed and updated periodically to assimilate progressive technological developments. To remain relevant, it must be modified as technological advances are made and as new data come to light. Suggestions for improving this standard are invited. Comments and suggest
