Standard Guide for Design and Evaluation of Primary Flexible Packaging for Medical Products

SIGNIFICANCE AND USE
4.1 This design and evaluation guide describes multiple categories for evaluating flexible medical packages and packaging materials. These include safety, barrier, material and package performance attributes and characteristics, package integrity, visibility and appearance, processing, printed ink, distribution simulation, and conditioning.  
4.2 The intent of this design and evaluation guide is to evaluate all cited categories and select those that are applicable. Once the product has been characterized and the sterilization methodology has been defined, there are numerous sets of requirements for any specific package. This design and evaluation guide provides an avenue for assessing these requirements and choosing test methods for both evaluating the package design and monitoring package compliance.
Note 1: Many of the standards included in this guide are consensus standards that are recognized by the United States Food and Drug Administration (FDA). Selection and use of a U.S. FDA recognized consensus standard is voluntary and the sole responsibility of the user in determining its applicability. For further information, consult the U.S. FDA Standards and Conformity Assessment Program at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatoryassistance/standards-and-conformity-assessment-program  
4.3 Product characterization shall include mass or weight, geometry (length and width, height, and shape) and product composition.  
4.4 All categories must be considered for applicability.  
4.5 The Summary of Test Methods for Medical Packaging Design and Evaluation (Fig. 1) provides a compact graphical presentation of the test methods referenced in this guide.
SCOPE
1.1 This guide provides directions for the design and evaluation of primary flexible packages for medical products. The package materials must be selected appropriately for manufacturing process, end use, and the product being packaged.  
1.2 This guide provides a compendium of test methods, practices, and procedures. Specific individual test methods must be selected based on the pertinent characteristics of the specific product to be packaged and the purpose for testing, research and development, or compliance. Not all test methods will be applicable.  
1.3 This guide does not address acceptability criteria, which need to be determined jointly by the package producer and the medical products manufacturer.  
1.4 This guide does not assess the product to be packaged or the sterilization method to be used.  
1.5 The units cited in the referenced standard should be used.  
1.6 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.

Standard Test Methods for Measurement of Torque Retention for Child Resistant and Non-Child Resistant Packages with Continuous Thread Closures Using Automated Torque Testing Equipment

SIGNIFICANCE AND USE
5.1 This test method allows for the measurement of the torque retention properties of container/continuous thread closure systems of various designs, materials, and manufacture, and is suitable for package development and engineering evaluation.  
5.2 Each test method can be used for the evaluation of non child resistant container/continuous thread closure systems under controlled conditions such as when the application torque is known and the applied downward force to the closure is zero or for Type I, style “A” push down and turn child resistant container/continuous thread closure systems under controlled conditions such as when the application torque and the applied downward force to the closure is known.  
5.3 This test method measures torque retention properties of container/continuous thread closure systems with the use of an automated transducer based torque meter operating at a known rotational velocity (rpm) or known torque ramp.  
5.4 This test method is intended for measurement of dry torque only.
SCOPE
1.1 These test methods evaluate the torque retention of continuous thread closures on containers with matching finishes, for predetermined environmental conditions over time. Methods are defined for both Type I, style “A” push down and turn Type II2 child resistant and non child resistant type closures.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
Note 1: The SI unit system is the recommended system.  
1.3 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.

ASTM F2475-20(Guide)
Standard Guide for Biocompatibility Evaluation of Medical Device Packaging Materials

SIGNIFICANCE AND USE
5.1 The compatibility of packaging materials with a medical device is a requirement of many regulatory bodies. Since most medical devices are used or implanted in, around, or on the human body, the benefits of these devices must outweigh the risks. Therefore, the packaging materials that come in contact with the medical device must also be evaluated and determined to be safe for use with the human body in that they have no negative impact on the physical, chemical, or biological properties of the device. This evaluation may include both a study of relevant experience with, and actual testing of, packaging materials. Such an evaluation may result in the conclusion that no testing is needed if the material has a demonstrable history of safe use in the specific role that is the same as that of the package under design.  
5.2 The medical device manufacturer determines the need for appropriate testing, with consideration of the device/package interactions, if any. When screening information is needed regarding the biocompatibility of the packaging, cytotoxicity testing from the supplier is typically performed.
SCOPE
1.1 This guide provides information to determine the appropriate testing for biocompatibility of medical device packaging materials that have the potential to contact the patient directly or indirectly.  
1.2 This guide does not apply to secondary or tertiary packaging materials.  
1.3 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.  
1.4 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.

Standard Guide for Packaging Test Method Validation

SIGNIFICANCE AND USE
4.1 Addressing consensus standards with inter-laboratory studies (ILS) and methods specific to an organization. Test methods need to be validated in many cases, in order to be able to rely on the results. This has to be done at the organization performing the tests but is also performed in the development of standards in inter-laboratory studies (ILS), which are not substitutes for the validation work to be performed at the organization performing the test.  
4.1.1 Validations at the Testing Organization—Validations at the test performing organization include planning, executing, and analyzing the studies. Planning should include description of the scope of the test method which includes the description of the test equipment as well as the measurement range of samples it will be used for, rationales for the choice of samples, the amount of samples as well as rationales for the choice of methodology.  
4.1.2 Objective of ILS Studies—ILS studies (per E691-14) are not focused on the development of test methods but rather with gathering the information needed for a test method precision statement after the development stage has been successfully completed. The data obtained in the interlaboratory study may indicate however, that further effort is needed to improve the test method. Precision in this case is defined as the repeatability and reproducibility of a test method, commonly known as gage R&R. For interlaboratory studies, repeatability deals with the variation associated within one appraiser operating a single test system at one facility whereas reproducibility is concerned with variation between labs each with their own unique test system. It is important to understand that if an ILS is conducted in this manner, reproducibility between appraisers and test systems in the same lab are not assessed.  
4.1.3 Overview of the ILS Process—Essentially the ILS process consists of planning, executing, and analyzing studies that are meant to assess the precision of a tes...
SCOPE
1.1 This guide provides information to clarify the process of validating packaging test methods specific for an organization utilizing them as well as through inter-laboratory studies (ILS), addressing consensus standards with inter-laboratory studies (ILS) and methods specific to an organization.  
1.1.1 ILS discussion will focus on writing and interpretation of test method precision statements and on alternative approaches to analyzing and stating the results.  
1.2 This document provides guidance for defining and developing validations for both variable and attribute data applications.  
1.3 This guide provides limited statistical guidance; however, this document does not purport to give concrete sample sizes for all packaging types and test methods. Emphasis is on statistical techniques effectively contained in reference documents already developed by ASTM and other organizations.  
1.4 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.  
1.5 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.

This guide provides a uniform approach for conditioning of plastic packaging intended for liquid hazardous materials (dangerous goods).  
4.2 The hazardous materials (dangerous goods) regulations certification process requires that plastic packagings undergo special preparations before performing the UN drop test. The regulations do not include uniform procedures for conducting special preparations. Non-uniform procedures allow for differences in methods between test facilities which may result in different test results.  
4.3 49 CFR 178.603(c) state that special conditioning for drop testing is required for all plastic drums, plastic jerricans, plastic boxes (other than expanded polystyrene boxes), composite packagings (plastic material), and combination packagings with plastic inner packagings (other than plastic bags intended to contain solids or articles). It further states that drop testing shall be conducted when the temperature of the test sample (packagings and contents) has been reduced to –18 °C or lower. Test liquids shall be kept in the liquid state, if necessary, by the addition of antifreeze. Water/antifreeze solutions with a minimum 0.95 specific gravity for testing at –18 °C or lower are considered acceptable test liquids. These conditioning requirements also apply to IBCs and Large Packagings. Refer to 49 CFR §178.810(b)(4) and §178.965(c), respectively.  
4.4 A 24-hour conditioning period may not be sufficient time for the packaging and contents to reach the required temperature.  
4.5 This guide provides additional information not in the regulations that will facilitate consistent test sample conditioning among test facilities. The information and guidance provided here are intended to meet or exceed the minimum requirements of the regul...
SCOPE
1.1 This guide is intended to provide a standardized method and a set of basic instructions for special preparation conditioning of drop test samples being subjected to United Nations (UN) performance-oriented packaging certification as required by United States Department of Transportation Title 49 Code of Federal Regulations (49 CFR) and the United Nations Recommendations on the Transport of Dangerous Goods (UN).  
1.2 This guide provides guidance on conditioning test samples for drop testing plastic Non-Bulk Packaging, Intermediate Bulk Container (IBC), and Large Packaging designs intended for liquid hazardous materials (dangerous goods) as required by 49 CFR §178.603(c)(1), §178.810(b)(4), and §178.965(c), respectively. This guide also provides the minimum information that should be documented when conducting special preparation conditioning.
