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

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.  
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.

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.

ASTM E3244-23(Practice)
Standard Practice for Integrity Assurance and Testing of Single-Use Systems

SIGNIFICANCE AND USE
4.1 This practice provides:  
4.1.1 A holistic approach to evaluate risks associated with an integrity breach in a SUS, considering its life cycle from development to disposal.  
4.1.2 An overview of physical and microbial test methods that could be applicable to SUS testing, for qualification and validation purposes, as well as for routine testing.  
4.1.3 Information on the main challenges faced when testing SUSs for integrity.  
4.2 This practice can be used by SUS suppliers and SUS end users to define an integrity assurance strategy for SUSs, with the relevant tests when appropriate.
SCOPE
1.1 This practice uses quality risk management (QRM) and life-cycle approach to establish integrity assurance of single-use systems (SUSs), such as but not limited to bag assemblies and liquid transfer sets for processing, storage, and shipping of (bio)pharmaceutical products. It gives recommendations to identify failure modes and risks associated with such systems and their use-cases and how to identify the relevant leak(s) of concern. Integrity assurance in this context is limited to the barrier properties of the SUS, linked to microbial integrity and bioburden control (product quality) and liquid product loss (operator and environmental contamination). The required level of integrity assurance will depend on how critical the application is and can be interpreted in different ways. It can also vary between processes and applications used for different modalities (for example, advanced therapies). Other package barrier properties different from that, such as but not limited to gas barrier properties for gas headspace preservation, as well as porous barrier packages are not considered. Specific aspects how to address the contamination control strategy (CCS) for SUS are also described in chapters 8.131ff of the new Revision of Annex 1 (1),2 including chapter 8.137 regarding SUS integrity.  
1.2 The test method overview provides descriptions that focus on the standard test setup and the identification of challenges in combination with SUSs. Details, including specific test setups, test parameter, and result interpretation, are not discussed. For more detailed information refer to Test Method E3251 for microbial test methods, and to Test Method E3336 for physical test methods.  
1.3 This practice is not intended to apply to the use of single-use technology for primary containers, combination products (products composed of any combination of a drug, device, or biological product), or devices. Appropriate procedures related to these products are discussed in documents covering the integrity assurance for primary containers (2) or medical products (1, 3).  
1.4 Techniques and procedures for complaint management and root cause analysis related to integrity failures are also not discussed.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.6 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.  
1.7 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 Testing of Hazardous Materials (Dangerous Goods) Packagings

ABSTRACT
This guide identifies the key information required to ensure that selected packaging will pass the United Nations (UN) packaging certification at the level that is appropriate for its intended use. This guide covers test procedures for transportation of hazardous material packagings for net masses except those used for infectious substances, radioactive materials, cylinders, and other receptacles for gases and does not replace domestic or international requlatory requirements for hazardous material packagings. The UN performance tests are based on the degree of hazard posed by the proposed materials to be packaged which are also assigned to a specific packing group. Only packaging designs that meet the UN performance standards are to be marked with a UN mark. Tests include drop test, leakproofness test, stack test, vibration test, pressure differential test, hydrostatic pressure test, and cobb water absorption test.
SIGNIFICANCE AND USE
4.1 The UN performance tests are based on the degree of hazard presented by the proposed hazardous material(s) to be packaged.  
4.2 Substances and articles which are hazardous are assigned to a specific packing group as defined in 3.8.1 and may be determined by referencing 49 CFR 172.101 hazardous materials table.  
4.3 Only packaging designs that have been successfully tested to the UN performance standards as defined in 3.8.2 may have the UN specification mark applied to the outer packaging. Hazardous Materials may not be transported in a packaging that does not bear the appropriate UN specification markings unless otherwise authorized by the applicable competent authority.  
4.4 Packages successfully tested to the UN performance standards may or may not withstand the North American distribution environment. To further evaluate the suitability of the package it is strongly recommended that additional tests as detailed in Practice D4169 or other carrier specified test requirements be conducted.
SCOPE
1.1 This guide identifies the key information required for United Nations (UN) packaging certification to ensure the selected packaging will be certified to the appropriate level for its intended use and provides guidance for locating relevant sections of the United States Department of Transportation Title 49 Code of Federal Regulations (CFR). Consult with a regulatory specialist whenever needed.  
1.2 This guide provides assistance in determining the appropriate performance tests required to certify packaging designs to the United States Department of Transportation Title 49 Code of Federal Regulations performance oriented packaging standards based on the United Nations Recommendations on the Transport of Dangerous Goods..  
1.3 This guide covers the testing for transportation of hazardous materials (dangerous goods) packagings for net masses not exceeding 400 kg (880 lb) or capacities not exceeding 450 L (119 gal), excepting packagings for infectious substances, radioactive materials, cylinders and other receptacles for gases.  
1.4 This guide does not replace domestic or international regulatory requirements for hazardous materials packaging but is strongly recommended to be used in conjunction with those regulations.  
1.5 The user of this guide must be trained in accordance with the United States Department of Transportation Title 49 Code of Federal Regulations (49 CFR) as required by 172.700 and should be familiar with other applicable hazardous materials regulations such as: International Civil Aviation Organization (ICAO) Technical Instructions for the Safe Transport of Dangerous Goods by Air, and the International Maritime Dangerous Goods Code (IMDG Code) and carrier rules such as International Air Transport Association (IATA) Dangerous Goods Regulations.  
1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not...

ASTM D8135-17(2023)(Guide)
Standard Guide for Selection of Substitute, Non-hazardous, Particulate Solid Filling Substances for Packagings Subjected to the United Nations Performance Tests

SIGNIFICANCE AND USE
5.1 Regulations prescribing the test procedures for hazardous materials packaging allow for the substitution of non-hazardous fill materials for packaging performance tests with certain limitations prescribed and guidance offered (see 49 CFR 178.602(c)). This regulatory guidance has proven to be flexible enough, in common industry practice, to produce variations in the selection of fill materials for package performance tests sufficient to cause inconsistent and non-repeatable test results. This variation creates significant problems in product liability, packaging selection and regulatory enforcement in this highly regulated industry. Use of this guide should enhance uniformity in test procedures.  
5.2 Consistent and repeatable test results coupled with clear test fill product descriptions will enhance transportation safety by simplifying packaging selection. This will also increase the general level of confidence that package testing, manufacture, and use are being guided by sound, generally accepted engineering principles. It also aids in clarifying expectations between the packaging industry and the regulatory authorities.  
5.3 The guide will be used by packaging manufacturers and packaging test labs to create packaging test plans that meet customer needs and conform to the HMR. In addition, for the user of a packaging, certain information about the type and physical characteristics of the material used to test the packaging must be available in the test report and/or notification instruction to allow evaluation of whether a particular packaging was tested with a substitute material appropriate for the hazardous material to be shipped.
SCOPE
1.1 The purpose of this guide is to clarify the selection, use, and description criteria of non-hazardous particulate solid substitutes used to replace hazardous materials for the purpose of performance testing packagings. This includes identification of the physical parameters of substitute non-hazardous solid test fill materials that may affect packaging performance and test results and should be considered when selecting and describing a test fill material that conforms to the requirements of the Hazardous Materials Regulations (HMR). This guide is intended for use with package testing procedures for particulate solid materials that have flow characteristics. It is not intended for use with hazardous articles.  
1.2 This guide provides information to assist packaging users, manufacturers, and performance testing service suppliers regarding the types of physical properties that should be considered when selecting substitute filling substances for the testing, certification and manufacture of packagings under the United Nations packaging protocols (UN Recommendations on the Transport of Dangerous Goods-Model Regulations) as adopted by US DOT in 49 CFR HMR.  
1.3 This guide provides the suggested minimum information concerning the physical characteristics of the filling substances that should be documented in the certification test report and notification to users to allow for test repeatability and analysis, and to provide guidance to the user of a packaging of pertinent physical differences between potential hazardous lading and the filling substance with which the packaging was tested.  
1.4 This guide does not purport to address regulatory requirements regarding the compatibility of filling substances with transport packagings. Compatibility requirements must be assessed separately, but it should be noted that under certain national and international dangerous goods regulations, the selection of the filling substances for package performance testing may be prescribed with respect to chemical compatibility requirements.
Note 1: Under the US HMR determination of packaging compatibility with a particular hazardous fill material is “the responsibility of the person offering the hazardous material for transportation” as prescribed in 49 CFR §...

ASTM D4332-22(Practice)
Standard Practice for Conditioning Containers, Packages, or Packaging Components for Testing

SIGNIFICANCE AND USE
4.1 Many materials from which containers and packages are made, especially cellulosic materials, undergo changes in physical properties as the temperature and the relative humidity (RH) to which they are exposed are varied. Therefore, the package should be placed and kept in a specified atmosphere for a length of time such that subsequent measurements of physical properties will be meaningful and reproducible.  
4.2 The conditions described in this practice are either historically accepted standard conditions or special laboratory conditions chosen to represent particular phases of the distribution environment. These special conditions do not necessarily duplicate actual field conditions, but tend to simulate them and have effects on packages and materials which may be related to their field performance.
SCOPE
1.1 This practice provides for standard and special conditioning and testing atmospheres that may be used to simulate particular field conditions that a container, package, or packaging component may encounter during its life or testing cycle.  
1.2 This practice describes procedures for conditioning these containers, packages, or packaging components so that they approach or reach equilibrium with the atmosphere to which they may be exposed. This standard is commonly used for conditioning when conducting transit simulation tests.  
1.3 Practice D685 should be used as the relevant conditioning standard when quantification of box compression strength at standard atmosphere conditions is required.  
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.
