Standard Test Method for Odor or Flavor Transfer or Both from Rigid Polymeric Packaging

Standard Test Method for Odor or Flavor Transfer or Both from Rigid Polymeric Packaging

SIGNIFICANCE AND USE
This test method is designed for use by a trained sensory panel experienced in using an intensity scale or rank ordering and familiar with the descriptive terminology and references associated with the packaging materials. Data analysis and interpretation should be conducted by a trained and experienced sensory professional. See Refs (3,4) for discussions on panelist screening and training.
This test method should be considered as a screening technique for suppliers and end-users to use in assessing the odor or flavor impact or both of rigid packaging. The application of this test method will result in a PPS or rank data. The determination for suitability of a package for a particular end-use should be based on a set of predetermined criteria including the PPS or rank score. Information obtained from the transfer tests can also be used to evaluate the origin of any transferred tastes or odors.
SCOPE
1.1 This test method covers a recommended procedure for examining odor or flavor properties or both of rigid polymeric packaging closures and fillable materials.
1.2 This test method can be used for single materials or coextruded materials that are foam molded, injection molded, blow molded, compression molded, or thermoformed polymers.
1.3 The focus of this test method is the evaluation of molded polymer in terms of the transfer of package-related odors, flavors, or both, to water and other model systems (bland food simulants). Rigid packaging forms vary considerably in type, size, and shape. Thus, customizing the exact procedure for dealing with the physical requirements for individual packages is the responsibility of the user.
1.4 This test method assumes testing of the materials at a one-time point; shelf-life testing is not included.
1.5 Refer to Test Method E 1870 for the evaluation of inherent odor of packaging material by confinement tests.
1.6 This test method provides sample preparation procedures and two methods of evaluation.
1.6.1 The package performance score method allows for the comparison of any molded polymer sample to another.
1.6.2 The ranking method allows for comparison of samples within the currently tested set only.
1.6.3 The preparation of samples is consistent regardless of the method of evaluation used.
1.7 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.
1.8 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 and health practices and determine the applicability of regulatory limitations prior to use.

Standard Practice for Determination of Contamination in Recycled Poly(Ethylene Terephthalate) (PET) Flakes and Chips Using a Plaque Test

SIGNIFICANCE AND USE
5.1 Presence of paper, metal, or incompatible polymer contamination in poly(ethylene terephthalate) renders the recycled polymer unfit for use in secondary product manufacturing operations. This procedure is useful for identifying different types of contamination in recycled PET flakes.
SCOPE
1.1 This practice covers an indication of the quality of recycled transparent poly(ethylene terephthalate) by examination of a wafer or plaque formed by melting a representative sample and quenching it to prevent crystallization.  
1.2 Specific contaminants and impurities such as aluminum particles, dirt particles, paper, and fibers are identified in the transparent wafer. This method is only limited to contamination observable through visual methods. If there are low levels (0–200 ppm) of certain types of contamination, which are transparent and partially/wholly miscible with PET, they will not be apparent through this method.  
1.3 The overall color of the plaque is indicative of oxidizable contaminants such as ethylene-vinyl acetate (EVA) glue residue and the number of bubbles present in the plaque gives an indication of the moisture content of the sample.  
1.4 Units—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.

Standard Test Method for Dynamic Shock Cushioning Characteristics of Packaging Material

SIGNIFICANCE AND 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.
SCOPE
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. The SI units given in parentheses are for information only.  
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.

Standard Specification for Printed, Pressure-Sensitive Adhesive Labels for Use in Extreme Distribution Environments

ABSTRACT
This specification provides a standard means for testing and measuring the performance characteristics of printed, pressure-sensitive adhesive labels for containers, particularly containers to be used in extreme distribution environments (for example, hazardous materials labels, aerospace, military containers). For the purposes of this specification, an extreme distribution environment is one in which it can be reasonably expected to experience direct exposure to deteriorating chemicals, weather, elevated/cold temperatures, and other environmental and physical elements for an extended period of time. This specification includes standard laboratory test methods to simulate exposure to various conditions and measure associated degradation of required performance characteristics. The data from these methods can be used as acceptance criteria between a supplier and customer. This specification covers the physical properties of the labels, as well as workmanship, finish and appearance, acceptance criteria, testing procedures, reporting of all the steps taken, certification, and preparation for delivery.
SCOPE
1.1 This specification provides a standard means to test and measure performance characteristics of printed, pressure-sensitive adhesive labels for containers, particularly containers to be used in extreme distribution environments (for example, hazardous materials labels, aerospace, military containers). For the purposes of this specification, an extreme distribution environment is one in which it can be reasonably expected to experience direct exposure to deteriorating chemicals, weather, elevated/cold temperatures, and other environmental and physical elements for an extended period of time.  
1.2 Units—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.  
1.3 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 Practice for Conditioning Flexible Barrier Materials for Flex Durability

SIGNIFICANCE AND USE
5.1 This practice is valuable in determining the resistance of flexible packaging materials to flex-formed pinholes. Conditioning levels A, B, or C are typically used. Reference Practice E171 and Guide F2097.  
5.2 Conditions D and E are typically used for determining the effect of flexing on barrier properties and transmission rates related to gas and/or moisture.  
5.3 This practice does not measure or condition materials for abrasion related to flex failure.  
5.4 Failures in the integrity of one or more of the plies of a multi-ply structure may require alternative testing. Supplementary permeation testing using gas or water vapor can be used in conjunction with the flex conditioning to measure the loss of ply integrity. Other test methods may be used after flexing for assessment of presence of pinholes. For a list of test methods, refer to Guide F2097.
FIG. 1 Planar Evolution of Gelbo Shaft Helical Groove 30.70 mm [1.20 in.] Diameter Shaft  
5.4.1 The various conditions described in this practice are to prevent evaluating a material structure with an outcome of too many holes to effectively count (normally greater than 50), or too few to be significant (normally less than five per sample). Material structure, testing basis, and a mutual agreement with specified objectives are to be considered in the selection of conditioning level for testing.
SCOPE
1.1 This practice covers conditioning of flexible barrier materials for the determination of flex resistance. Subsequent testing can be performed to determine the effects of flexing on material properties. These tests are beyond the scope of this practice.  
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.  
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.
