ASTM F2338-09(2020)(Test Method)
Standard Test Method for Nondestructive Detection of Leaks in Packages by Vacuum Decay Method

SIGNIFICANCE AND USE
5.1 Leaks in medical device, pharmaceutical, and food packages may result in the ingress of unwanted gases (most commonly oxygen), harmful microbiological, or particulate contaminants. Package leaks may appear as imperfections in the package components themselves or at the seal juncture between mated components. The ability to detect leaks is necessary to ensure consistency and integrity of packages.  
5.2 After initial set-up and calibration, individual test operation may be semi-automatic, automatic, or manual. The test method permits non-destructive detection of leaks not visibly detectable. The test method does not require the introduction of any extraneous materials or substances, such as dyes or gases. However, it is important to physically mask or block off any package porous barrier surface during the test to prevent rapid loss of chamber vacuum resulting primarily from gas migration through the porous surface. Leak detection is based solely on the ability to detect the change in pressure inside the test chamber resulting from gas or vapor egress from a package challenged with vacuum.  
5.3 This test is a useful research tool for optimizing package sealing parameters and for comparatively evaluating various packages and materials. This test method is also applicable to production settings as it is rapid, non-invasive, and non-destructive, making it useful for either 100 % on-line testing or to perform tests on a statistical sampling from the production operation.  
5.4 Leak test results that exceed the permissible limits for the vacuum decay test are indicated by audible or visual signal responses, or both.
SCOPE
1.1 Test Packages—Packages that can be nondestructively evaluated by this test method include:  
1.1.1 Rigid and semi-rigid non-lidded trays.  
1.1.2 Trays or cups sealed with porous barrier lidding material.  
1.1.3 Rigid, nonporous packages.  
1.1.4 Flexible, nonporous packages.  
1.2 Leaks Detected—This test method detects package leaks by measuring the rise in pressure (vacuum loss) in an enclosed evacuated test chamber containing the test package. Vacuum loss results from leakage of test package headspace gases and/or volatilization of test package liquid contents located in or near the leak. When testing for leaks that may be partially or completely plugged with the package’s liquid contents, the test chamber is evacuated to a pressure below the liquid’s vaporization pressure. All methods require a test chamber to contain the test package and a leak detection system designed with one or more pressure transducers. Test method sensitivities cited below were determined using specific product-package systems selected for the precision and bias studies summarized in Table 1. Table 1 also lists other examples of relevant product-package systems that can be tested for leakage by vacuum decay.    
1.2.1 Trays or Cups (Non-lidded) (Air Leakage)—Hole or crack defects in the wall of the tray/cup of at least 50 μm in diameter can be detected. Nonlidded trays were tested at a Target Vacuum of –4·E4 Pa (–400 mbar).  
1.2.2 Trays Sealed with Porous Barrier Lidding Material (Headspace Gas Leakage)—Hole or crack defects in the wall of the tray/cup of at least 100 μm in diameter can be detected. Channel defects in the seal area (made using wires of 125 μm in diameter) can be detected. Severe seal bonding defects in both continuous adhesive and dot matrix adhesive package systems can be detected. Slightly incomplete dot matrix adhesive bonding defects can also be detected. All porous barrier lidding material packages were tested at a Target Vacuum of –4·E4 Pa (–400 mbar). The sensitivity of the test for porous lidded packages is approximately E-2 Pa·m3·s-1 using a calibrated volumetric airflow meter.  
1.2.3 Rigid, Nonporous Packages (Headspace Gas Leakage)—Hole defects of at least 5 μm in diameter can be detected. Plastic bottles with screw caps were tested at a target vacuum...

Standard Test Method for Determining Compressive Resistance of Shipping Containers, Components, and Unit Loads

SIGNIFICANCE AND USE
4.1 Compressive resistance is one of the properties used to evaluate the ability of shipping containers, components, and unit loads to successfully survive the compressive forces they are subjected to during storage and distribution (see Note 1).
Note 1: For constant load test refer to Test Method D4577.  
4.2 Compressive resistance may be determined with either fixed- or swiveled-platen-type testing machines. However, a fixed-head compression machine is required to perform edge-to-edge and corner-to-corner orientations on test specimens (see Note 2). Also, unit loads are generally tested only in the top-to-bottom orientation.
Note 2: Fixed-platen machines generally cause corrugated box specimens to fail at their strongest point, while swivel-platen machines cause corrugated box specimens to fail at their weakest point.5 The swiveled platen is allowed to move to the weakest point of the container.
SCOPE
1.1 This test method covers compression tests on shipping containers (for example, boxes and drums) or components, or both. Shipping containers may be tested with or without contents. The procedure may be used for measuring the ability of the container to resist external compressive loads applied to its faces, to diagonally opposite edges, or to corners. This test method covers testing of multiple containers or unit loads, in addition to individual shipping containers, components, materials, or combination thereof.  
1.2 The test method of applying load may be used to compare the characteristics of a given design of container with a standard, or to compare the characteristics of containers differing in construction.  
1.3 This test method is related to TAPPI T 804. This test method fulfills the requirements of International Organization for Standardization (ISO) Test Method 12048. The ISO standards may not meet the requirements for this test method.  
1.4 The test may be conducted with the container loaded with contents and interior packaging in cases where the contents share the load.  
1.5 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 considered 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 Test Methods for Internal Pressurization Failure Resistance of Unrestrained Packages

SIGNIFICANCE AND USE
5.1 These test methods provide a rapid means of evaluating tendencies for package failure when the package is exposed to a pressure differential. Pressure differentials may occur during processes such as sterilization and transportation.  
5.2 These test methods are frequently used to quickly evaluate packages during the manufacturing process and at various stages of the package's life cycle.  
5.3 If correlations between pieces of test equipment are to be made, it is important that all parameters of the test method be exactly the same. Typical parameters may include, but are not limited to, package size, material, seal configuration, test equipment, rate of air flow into the package, sensitivity (machine response to pressure drop), and position of test article (see Fig. 1).
FIG. 1 Open Package Test Positions  
5.4 These test methods do not necessarily provide correlation with actual package seal strength as typically measured using Test Method F88 (or equivalent).
SCOPE
1.1 These test methods explain the procedure for determining the ability of packages to withstand internal pressurization.  
1.2 The burst test increasingly pressurizes the package until the package fails.  
1.3 The creep test maintains a specified pressure for a specified time or until the package fails.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
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.

Standard Practice for Performance Testing of Packages for Single Parcel Delivery Systems

SIGNIFICANCE AND USE
4.1 This practice provides a guide for the evaluation of shipping units in accordance with a uniform system, using established test methods at levels representative of those occurring in actual distribution. The recommended test levels are based on available information on the shipping and handling environment, and current industry/government practice and experience. The tests should be performed sequentially on the same containers in the order given. For use as a performance test, this practice requires that the shipping unit tested remain unopened until the sequence of tests are completed. If used for other purposes, such as package development, it may be useful to open and inspect shipping units at various times throughout the sequence. This may, however, prohibit evaluating the influence of the container closure on container performance.
SCOPE
1.1 This practice provides a uniform basis of evaluating, in a laboratory, the ability of shipping units, weighing up to but not exceeding 150 lb (68 kg), intended for the single parcel delivery system to withstand the hazards associated with the distribution environment. This is accomplished by subjecting them to a test plan consisting of a sequence of anticipated hazard elements encountered in the distribution cycles. This practice is not intended to supplant material specifications or existing pre-shipment test procedures.  
1.2 The suitability of this practice for use with hazardous materials has not been determined.  
1.3 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 considered 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 1.1.
