25、 by Technical Committee ISO/TC 84, Devices for administration of medicinal products and intravascular catheters.This second edition cancels and replaces the first edition (ISO 11608-2:2000), which has been technically revised.ISO 11608 consists of the following parts, under the general title Needle-

26、based injection systems for medical use Requirements and test methods: Part 1: Needle-based injection systems Part 2: Needles Part 3: Finished containers Part 4: Requirements and test methods for electronic and electromechanical pen-injectors Part 5: Automated functionsiv ISO 2012 All rights reserve

27、dBS EN ISO 11608-2:2012ISO 11608-2:2012(E)IntroductionThis part of ISO 11608 covers sterile double-ended needles intended for single use in conjunction with needle-based injection systems (e.g. pen injectors). These needles are often referred to as pen needles.The devices described in this part of I

28、SO 11608 are designed to be used with the devices described in ISO 11608-1 and ISO 11608-3.The first edition of this part of ISO 11608 introduced the concept of interchangeability and the labelling designations “Type A” (i.e.interchangeable) and “non-Type A” for needles and container closure systems

29、. Since its promulgation, experience has shown that the complexity of these systems makes it very difficult to ensure functional compatibility as defined in the different parts of this International Standard, particularly when products are made by different manufacturers and the design is not verifi

30、ed as a system. Based on this experience, it is believed that the Type A designation does not represent adequate guidance to the user in making decisions on the compatibility of needles and container closures with specific needle-based injection systems (NIS). As such, the labelling designation “Typ

31、e A” has been removed.This second edition of ISO 11608-2 addresses functional compatibility of the system through testing in accordance with Clause 11. Flow rate is introduced as a new parameter. The sampling plans for inspection selected for this part of ISO 11608 are intended to verify, at a high

32、confidence level, the manufacturers ability to manufacture one “lot” of needles that conforms to the critical product attributes. The sampling plans for inspection do not replace the more general manufacturing quality systems that appear in standards on quality systems, for example ISO 9000.This par

33、t of ISO 11608 does not specify requirements or test methods for freedom from biological hazards because no international agreement on the methodology and the pass/fail criteria has been reached. Guidance on biological tests relevant to double-ended needles is given in ISO 10993-1, and it is suggest

34、ed that manufacturers take this guidance into account when evaluating products. Such evaluation should include the effects of the sterilization process. However, national regulations might exist in some countries, which might take precedence over the guidance in ISO 10993-1.In some countries, nation

35、al regulations exist and their requirements might supersede or complement this part of ISO 11608.
