4.1 Contaminants may enter the package through leaks. Alternatively, product may be lost from the package through leaks. These leaks are frequently found at seals between package components of the same or dissimilar materials.4.2 Ingress or egress of gas or moisture through leaks in a package can also degrade sensitive contents.4.3 There is no general agreement concerning the level of leakage that is likely to be deleterious to a particular package. However, since these tests are designed to detect leakage, components that exhibit any indication of leakage may be rejected.4.4 These procedures are suitable for use to verify and locate leakage sites. They are not quantitative. No indication of leak size can be inferred from the test. Therefore, this method is employed as a go/no-go test.4.5 These tests are destructive. No package or component test samples exposed to dye penetration testing may be used for final product packaging.1.1 Method A of this test method defines a procedure that will detect and locate a leak equal to or greater than a channel formed by a 50 µm [0.002 in.] wire in the edge seals of a nonporous package. A dye penetrant solution is applied locally to the seal edge to be tested for leaks. After contact with the dye penetrant for a minimum specified time, the package is visually inspected for dye penetration or, preferably, the seal edge is placed against an absorbent surface and the surface inspected for staining from the dye.1.2 Method B for this test method also defines a procedure that will detect and locate a leak equal to or greater than 10 µm [0.00039 in] diameter in a nonporous flat sheet. The flat sheet is placed on an absorbent surface and then a dye penetrant is spread across the surface of the sheet, preferably using a small roller to apply pressure on the sheet to ensure adequate contact between the absorbent surface and the bottom surface of the sample being tested. The flat sheet is carefully removed and the absorbent surface is inspected for staining from the dye.1.3 These test methods are used for both transparent and opaque nonporous surfaces.1.4 These test methods require that the dye penetrant have good contrast to the materials being tested and/or the absorbent surface.1.5 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.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.

4.1 The following practices are to be used in obtaining samples that are representative of the lot being sampled. The methodology used will be dependent upon the size and type of material sampled and testing requirements.4.2 The following practices are intended for use in obtaining samples from material that is ready for sale and are not intended as sampling procedures for quality control purposes. These practices are to be used in obtaining a laboratory sample that will yield results serving as a basis for acceptance or rejection of the lot of material sampled. This does not preclude the use of these practices for quality control purposes.4.3 The following practices can be used to eliminate bias in sampling. The person or persons responsible for using these practices must be trained and they will be conscientious and timely in their use.4.4 An agreement between the producer and the consumer on location of sampling, either at the producer's plant or at the destination, is encouraged. Product quality can be affected through careless handling, improper protection, and delayed shipment. It is preferable to sample at the point of loading. The consumer has the right to witness the sampling practices being used.4.5 This practice may be used to provide a representative sample of lime or limestone products. Due to the variability of limestone and lime and the wide variety of sampling equipment, caution must be exercised in all stages of sampling, from system specification and equipment procurement to equipment acceptance testing and actually taking the final sample.1.1 This practice covers procedures for the collection and reduction of samples of lime and limestone products to be used for physical and chemical tests.1.2 This practice further covers inspection, rejection, retesting, packing, and marking of lime and limestone products as it may be used in the chemical, agricultural, and process industries.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. 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.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.

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.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.

5.1 This test method is intended to measure volatile organic compounds that are emitted from packaging materials under high-temperature conditions.5.2 This test method may be useful in assisting in the development and manufacture of packaging materials having minimal retained packaging ink/adhesive solvents.5.3 Modification of this procedure by utilizing appropriate qualitative GC detection devices such as a mass spectrometer in place of the flame ionization detector may provide identification of volatile organics of unknown identity.1.1 This test method covers determination of the amount of residual solvents released from within a packaging material contained in a sealed vial under a given set of time and temperature conditions and is a recommended alternative for Test Method F151.1.2 This test method covers a procedure for quantitating volatile compounds whose identity has been established and which are retained in packaging materials.1.3 The analyst should determine the sensitivity and reproducibility of the method by carrying out appropriate studies on the solvents of interest. The analyst is referred to Practice E260 for guidance.1.4 For purposes of verifying the identity of or identifying unknown volatile compounds the analyst is encouraged to incorporate techniques such as gas chromatography/mass spectroscopy, gas chromatography/infrared spectroscopy or other suitable techniques in conjunction with this test method.1.5 Sensitivity of this test method in the determination of the concentration of a given retained solvent must be determined on a case by case basis due to the variation in the substrate/solvent interaction between different types of samples.1.6 This test method does not address the determination of total retained solvents in a packaging material. Techniques such as multiple headspace extraction can be employed to this end. The analyst is referred to the manual supplied with the GC-Autosampling system for guidance.1.7 The values stated in SI units are to be regarded as the standard.1.8 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.1.9 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.

5.1 Seal attributes can be linked directly to a number of variables in process parameters, equipment, or material, as well as environmental (room temperature and relative humidity). Visual seal characteristics and defects can provide evidence of package integrity and production sealing problems.5.2 Visual seal defects often will be the first indication of heat sealing process variation. They also will indicate a lack of, or potential compromise to, package integrity after physical package performance testing.1.1 This test method covers the determination of channels in the package seal down to a width of 75 μm [0.003 in.] with a 60–100 % probability (see Section 8).1.1.1 The ability to visually detect channel defects in package seals is highly dependent on the size of channel, the degree of contrast from sealed and unsealed areas, the amount and type of adhesive between the two package layers, reflecting light angle, types of material used, the use of magnification, and the inspector's level of training and experience.1.2 This test method is applicable to packages with at least one transparent side so that the seal area may be clearly viewed.1.3 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.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 Dynamic cushioning test data obtained by this test method are applicable to the cushioning material and not necessarily the same as obtained in a package. In addition to the influence of the package, the data can also be affected by the specimen area, thickness, loading rate, and other factors.1.1 This test method covers a procedure for obtaining dynamic shock cushioning characteristics of packaging materials through acceleration-time data achieved from dropping a falling guided platen assembly onto a motionless sample. This test method does not address any effects or contributions of exterior packaging assemblies.1.2 The data acquired may be used for a single point or for use in developing a dynamic cushion curve for the specific material being tested. Such data may be used for comparison among different materials at specific input conditions, or qualifying materials against performance specifications. Caution should be used when attempting to compare data from different methods or when using such data for predicting in-package performance. Depending upon the particular materials of concern, correlation of such data (from among differing procedures or for predicting in–package performance) may be highly variable.NOTE 1: Alternative and related method for possible consideration is Test Method D4168.1.3 The values stated in inch-pound units are to be regarded as the standard.

This guide covers the standard for the calculation and the substantiation of recycled content of packaging papers and paperboard products. The mass balance approach shall be used to determine absolute recycled content. This guide also covers the recycled content that contain any amount or kind of recycled fiber. Methods to calculate and substantiate levels of such recycled fiber is also covered. Classes and types of paper and paperboard product include, but are not limited to, folding boxboard, set-up boxboard; linearboard and corrugating medium for use in corrugated containers; tubestock; carrier board, bag paper and other related packaging paper and paperboard products.1.1 This guide provides an approach for both the calculation and the substantiation of recycled content of finished packaging paper and paperboard products. A mass balance approach is recommended for use by manufacturers since no physical or chemical test method is currently available to determine absolute recycled content of a finished paper product. Calculations are based on time weighted average flows which are based on furnish component flow rates and consistency. Recommended approaches to the calculations include by batch or by time weighted average for a specific grade or similar grades. It is not recommended that average recycle content be allocated by mathematical apportionment rather than by actual fiber content. That is, if 50 % recycled fiber is used over time that is the time weighted average. One cannot use this same data to report 50 % of the production is 100 % recycled.1.1.1 Percentage calculations are based on lb/ton or kg/tonne with the time frame constrained by machine and grade (see 10.1.1.1 and 10.1.1.2).1.1.2 Pulping and recycling yields are not used in these calculations. The calculations of recycled fiber content in the finished product is solely a function of type of fibers in the furnish flows, the volume of flow and the time period considered.1.2 This guide covers (1) recycled content of packaging paper and paperboard products that contain any amount or kind of recycled fiber; and (2) methods to calculate and substantiate the level(s) of recycled fiber content claimed by an agreement between the buyer and the seller.1.2.1 This guide may be used with or without modification to calculate or substantiate the recycled content of packaging paper and paperboard products when recovered nonfibrous materials (for example, filler) are a part of the recycled fiber furnish. Limited guidance is provided for appropriate modifications to this guide for the determination of amount of recycled nonfibrous materials in paper products.1.3 This guide does not recommend either an amount or a kind of recycled fiber or material to use since (1) the amount and kind of recycled content in a packaging paper or paperboard product should be agreed upon between the buyer and the seller, and (2) the calculation and substantiation procedures recommended may be used for any amount or kind of recycled material agreed upon between the buyer and the seller.1.4 The mass balance calculation method recommended by this guide may or may not comply with applicable federal, state, or local laws for recycled content statements intended to be received by consumers. Limited guidance on content statements is in Appendix X1.1.5 The following safety hazards caveat pertains only to the test method portion, Section 10, of this guide: 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.1.6 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.

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.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.

4.1 This guide assists users in design and development of packaging intended for the protection of goods while they are in transit from point of origin to final destination. By following all steps of this guide, users will be assured that the most important factors are included in package design. In some cases, the sequence of steps may be changed, and often the steps may occur simultaneously with concurrent work activities.4.2 The design process focuses on protection from hazards of handling, storage, and shipping while recognizing the economics of all other facets of distribution, including packaging materials and labor, and transportation.4.3 In transport packaging, distribution is generally defined as inclusion of handling, storage, and transportation factors.1.1 This guide covers an approach to design of packaging for distributing goods through the hazards of handling, storage, and transportation.1.2 The principal content of this guide is the identification of the key steps involved in development of transport packages, including shipping containers, interior protective packaging, and unit loads. It is recognized that actual usage and application to individual design projects may vary appreciably without diminishing the value of the process. Consult with a packaging professional whenever needed.1.3 This guide is not intended for design of primary packaging unless the primary package is planned for use as a shipping container.1.4 The user of this guide must be aware of the carrier rules regarding packaging for shipment via each mode of transportation in which the transport package may move, such as the National Motor Freight Classification (less-than truckload) and the Uniform Freight Classification (railroad). For hazardous materials packaging, the packaging must perform to the requirements of the applicable modal regulations listed in Section 2.1.5 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.1.6 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.

5.1 The exposure-chamber method is a quantitative procedure for determining the microbial-barrier properties of porous materials under the conditions specified by the test. Data obtained from this test is useful in assessing the relative potential of a particular porous material in contributing to the loss of sterility to the contents of the package versus another porous material. This test method is not intended to predict the performance of a given material in a specific sterile-packaging application. The maintenance of sterility in a particular packaging application will depend on a number of factors, including, but not limited to the following:5.1.1 The bacterial challenge (number and kinds of microorganisms) that the package will encounter in its distribution and use. This may be influenced by factors such as shipping methods, expected shelf life, geographic location, and storage conditions.5.1.2 The package design, including factors such as adhesion between materials, the presence or absence of secondary and tertiary packaging, and the nature of the device within the package.5.1.3 The rate and volume exchange of air that the porous package encounters during its distribution and shelf life. This can be influenced by factors including the free-air volume within the package and pressure changes occurring as a result of transportation, manipulation, weather, or mechanical influences (such as room door closures and HVAC systems).5.1.4 The microstructure of a porous material which influences the relative ability to adsorb or entrap microorganisms, or both, under different air-flow conditions.1.1 This test method is used to determine the passage of airborne bacteria through porous materials intended for use in packaging sterile medical devices. This test method is designed to test materials under conditions that result in the detectable passage of bacterial spores through the test material.1.1.1 A round-robin study was conducted with eleven laboratories participating. Each laboratory tested duplicate samples of six commercially available porous materials to determine the Log Reduction Value (LRV) (see calculation in Section 12). Materials tested under the standard conditions described in this test method returned average values that range from LRV 1.7 to 4.3.1.1.2 Results of this round-robin study indicate that caution should be used when comparing test data and ranking materials, especially when a small number of sample replicates are used. In addition, further collaborative work (such as described in Practice E691) should be conducted before this test method would be considered adequate for purposes of setting performance standards.1.2 This test method requires manipulation of microorganisms and should be performed only by trained personnel. The U.S. Department of Health and Human Services publication Biosafety in Microbiological and Biomedical Laboratories (CDC/NIH-HHS Publication No. 84-8395) should be consulted for guidance.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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.

5.1 This practice provides a method for conditioning packaging systems using climatic conditions that occur in actual distribution. The recommended exposure levels are based on available information on shipping, handling and storage environments, current industry practices, and published studies. They are not absolute extremes, but recorded daily averages in cold and hot climates of the world.1.1 This practice provides a uniform basis for evaluating, in a laboratory, the ability of a packaging system to withstand a range of climatic stresses that a packaging system may be exposed to during distribution throughout the world and still provide the product protection from damage or alteration.1.2 This practice is designed as conditioning prior to testing for overnight or two-day delivery systems of a single parcel packaging system or as a standalone test for climatic stressing of packaging systems.NOTE 1: Practice F2825 climatic stressing or conditioning is short term in duration. Fiberboard containers are not expected to approach equilibrium moisture content at the climatic conditions used in Practice F2825. Therefore, Practice F2825 conditioning should not be used for distribution environments other than one- to two-day single parcel delivery as it may provide inaccurate or misleading test results for the fiberboard containers.1.3 This practice does not cover refrigerated, frozen food storage, or cryogenic storage conditions. Only the climatic environments encountered in various regions of the world are covered by this practice.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.
