4.1 Implantable medical device labeling often results in a variety of label formats and information prioritization. This variability can be seen not only across different manufacturers but also across different implant types.3 At present label design and layout is developed by a given manufacturer and represents balancing internal needs (such as manufacturing, distribution, and marketing), regulatory requirements within various markets, and end user needs (as identified by individual manufacturers performing “voice of the consumer” feedback on their label designs).4.2 At no fault to any given manufacturer, this process, along with the manner in which label information competes for available “real estate” on a package, often leads to variable prioritization of label information and highly variable label designs. The impact of this variability on patient care is not well documented within the published literature. An article from AAOS Now in 2009 described potential issues around label variability and gave anecdotal evidence of its impact.34.3 No published literature demonstrating a clear and conclusive impact on patient safety resulting from implant label variability was identified. Despite this lack of evidence, anecdotal observations and input from various involved individuals and organizations (surgeons, operating room nurses, hospital administrators, product representatives, and manufacturers) suggests a potential, although unproven, benefit for an increased standardization of implant labeling.4.4 The authors of this guide believe it is important to highlight that no universally accepted method for validation of a label’s effectiveness exists. Current validation methods consist of varying methods of customer feedback on an existing label design using formal customer questionnaires, informal customer feedback through individual polling, and internal manufacturer-driven studies. The label recommendations presented within this guide have not been validated as more or less effective than other existing implant labels currently in use.4.5 These recommendations have been developed through the collaboration of an ASTM-sponsored task group with representation from large and small orthopedic implant manufacturers, orthopedic surgeons (specifically the Biomedical Engineering Committee from the American Academy of Orthopedic Surgeons), healthcare facility administrators, operating room nurses, the U.S. Food and Drug Administration (FDA), and the Canadian Healthcare System. The task group utilized “voice of consumer” feedback from previous manufacturer label initiatives combined with input from various end users on the task group. This process did not identify any given implant label format as being more or less effective but only attempts to prioritize information and recommend a universal format for this information. A manufacturer may determine that an alternative format may be more effective for its internal processes and elect not to follow these recommendations.1.1 The goal of this guide is to recommend a universal label format (across manufacturers and various implants) of content and relative location of information necessary for final implant selection within an implant’s overall package labeling.1.2 This guide recommends package labeling for musculoskeletal based implants individually processed and packaged with the intent of being opened at the point of use, typically in the operating room.1.3 This guide identifies the necessary, “high priority” label content and recommendations for the layout and location of information for accurate implant identification by the end users in the operating room environment.1.4 This goal is achieved by creating a partitioned, secondary area of an implant’s package label or a separate label to present this information uniformly.1.5 The authors of this guide identified the competing needs of regulatory requirements, manufacturing/distribution, and implant identification. It is recognized through our task group’s efforts that, if a manufacturer elects to implement these recommendations, balancing these competing needs may necessitate changing a manufacturer’s internal processes, relabeling their entire inventory (either at a single point in time or over a defined time period), or accepting duplicate information on an implant’s package label. No additional compromises that would allow the primary goal of uniform implant label design across manufacturers were identified.1.6 It is not the intent of this guide to limit or dictate overall package labeling content.1.7 It is not the intent of this guide to supplant existing regulatory requirements (only to augment or complement existing regulatory label requirements).1.8 The use or application of multiple languages is not prevented by this guide; however, use of more than one language is discouraged on the implant selection sublabel (ISSL) defined in this guide. The language of choice is left to the manufacturer and should be dictated by the end user and regulatory requirements in the jurisdictions where the device is marketed. International symbols should also be considered to avoid the need for multiple ISSLs where possible.1.9 Use and implementation of this guide is optional and at the sole discretion of the implant’s manufacturer. It shall be implemented with the following considerations:1.9.1 The content and layout of any orthopedic implant label should be influenced by risk management activities and all label formats should be validated.1.9.2 If internal risk management activities recommend deviation from this guide, the manufacturer is discouraged from implementing a hybrid label that partially applies the principles and recommendations in this guide.1.10 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.11 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.12 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 The tensile elongation property determined by this practice is of value for the characterization of degradable materials. It is possible that the tensile elongation property will vary with specimen thickness, method of preparation, speed of testing, type of grips used, and manner of measuring test extension. Consequently, where precise comparative results are desired, these factors must be carefully controlled.4.2 It is acceptable to use the tensile elongation property to provide data for research and development and engineering design as well as quality control specifications. However, data from such tests cannot be considered significant for applications differing widely from the load-time scale of the test employed.4.3 Materials that fail by tearing give anomalous data that cannot be compared with those from normal failure.4.4 Before proceeding with this test method, reference needs to be made to the specifications of the material being tested. Any test specimen preparation, conditioning, dimensions, or testing parameters or a combination thereof, covered in the material specifications shall take precedence over those mentioned in this test method. If there are no material specifications, then the default conditions apply.1.1 This practice covers the determination of a degradation-end point (a brittle point) for degradable polyethylene/polypropylene films and sheeting less than 1.0 mm (0.04 in.) thick. This practice is not intended for determination of the rate or degree of degradation of a polyethylene/polypropylene film or sheet, but rather, to assess when in the course of its degradation under some condition, a brittle point is reached. If one wishes to monitor tensile elongation during the degradation process (such as when the tensile elongation is significantly greater than 5 %), Test Method D882 is recommended. This practice is not to be considered the only way of determining a degradation-end point.1.2 Tensile properties of plastics 1.0 mm (0.04 in.) or greater in thickness shall be determined in accordance with Test Method D638.1.3 Use a static weighing-constant rate of grip separation test. This procedure employs a constant rate of separation of the grips holding the sample and a static load cell.NOTE 1: This procedure is based on the use of grip separation as a measure of extension; however, the desirability of using extension indicators accurate to ±1.0 % or better as specified in Test Method D638 is recognized, and a provision for the use of such instrumentation is incorporated in the procedure.1.4 This procedure has been successful for determining the degradation end point of ethylene-carbon-monoxide copolymers and has screened successfully two other additive-type polyethylenes in a round robin test.1.5 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use.
