Standard Practice for Performing Accelerated Outdoor Weathering of Pressure-Sensitive Tapes Using Concentrated Natural Sunlight

Standard Practice for Performing Accelerated Outdoor Weathering of Pressure-Sensitive Tapes Using Concentrated Natural Sunlight

SIGNIFICANCE AND USE
This practice provides a means of qualitative assessments of outdoor weathering effects on pressure-sensitive tapes. The resistance of tapes to outdoor weathering is determined relative to the resistance of a control tape with known stability.
If tests described in this practice produce the same type of degradation as found in real-time exposures of the same materials, it is possible to use the results from these short-term tests to determine the quantitative effects of natural weathering.
The timing of exposure testing covering both outdoor conventional and outdoor accelerated exposure of this practice, using levels of ultraviolet solar radiation exposure (MJ/m2) of UV (295 to 385 nm) is an improvement in the timing of exposure testing. Testing specific levels of solar radiant exposure (MJ/m2) may be used to establish relative equivalent exposure, but the use of (MJ/m2 of UV (295 to 385 nm)) is the preferred method. , ,  
The radiant exposure (308 or 616 MJ/m2) suggested in this practice approximates one and two years, respectively, of exposure in the Southwest and Florida. Since all materials “weather” at different rates in different environments, results obtained using this practice should not be represented as equivalent to natural weathering until the degree of quantitative correlation has been established for the material tested in the environment of its use.
Note 1—The ultraviolet content of natural sunshine is time-of-year dependent, both qualitatively and quantitatively. Thus, wintertime testing requires longer exposure periods on the Flesnel-reflector test machines described to achieve equal ultraviolet energy deposition and a quantitative equal level of degradation concomitant with summertime testing.
SCOPE
1.1 This practice covers one procedure for the exposure of pressure-sensitive tapes to an accelerated outdoor weathering environment.  
1.2 This practice describes sample preparation and an accelerated outdoor environment to which it shall be exposed. It does not specify what observations or tests are to be performed on the material following exposure.  
1.3 The values stated in inch-pound units are to be regarded as the standard. The values 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 and health practices and determine the applicability of regulatory limitations prior to use.

Standard Practice for Performance Testing of Shipping Containers and 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 (1-13).6 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.  
4.2 For Distribution Cycle 18, as referred to in MIL-STD-2073–1, the use of this practice is defined in subsequent sections identified as DC-18.
SCOPE
1.1 This practice provides a uniform basis of evaluating, in a laboratory, the ability of shipping units to withstand the distribution environment. This is accomplished by subjecting them to a test plan consisting of a sequence of anticipated hazard elements encountered in various distribution cycles. This practice is not intended to supplant material specifications or existing preshipment test procedures.  
1.2 Consider the use of Practice D7386 for testing of packages for single parcel shipments.  
1.3 The suitability of this practice for use with hazardous materials has not been determined.  
1.4 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.  
1.5 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 Test Methods for Vibration Testing of Shipping Containers

SIGNIFICANCE AND USE
4.1 Shipping containers are exposed to complex dynamic stresses when subjected to vibration present in all transportation vehicles. Approximating the actual damage, or lack of damage, experienced in shipping may require subjecting the container(s) and contents to vibration inputs.  
4.2 Resonant responses during shipment can be severe and may lead to package or product failure. Identification of critical frequencies, and the nature of package stresses can aid in minimizing the effect of these occurrences.  
4.3 Vibration tests should be based on representative field data. When possible, the confidence level may be improved by comparing laboratory test results with actual field shipment data. It is highly recommended that one understand the most common failures to one’s products and packaging in distribution, and then attempt to replicate those failures in the laboratory. Once such replication is established, then that test can become the minimum necessary test for future packaged products to pass.  
4.4 Exposure to vibration can affect the shipping container, its interior packaging, means of closure, and contents. These tests allow analysis of the interaction of these components. Design modification to one or more of these components may be utilized to achieve optimum performance in the shipping environment.  
4.5 Methods A1 and A2, Repetitive Shock Tests,  are suitable for tests of individual containers that are transported unrestrained on the bed of a vehicle and may be suitable for tests of containers that might be subjected to repetitive shocks due to magnification of vibrations in unit loads or stacks.
Note 1: Methods A1 and A2 produce different vibration motions, and therefore, will generate different forces which may result in different damage modes and intensities. Results from these two methods may not correlate with one another.  
4.6 Method B, Single Container Resonance Test,  tests or determines the ability of an individual container and its inter...
SCOPE
1.1 These test methods cover vibration tests of filled shipping containers. Such tests may be used to assess the performance of a container, with its interior packing and means of closure, both in terms of its strength and of the protection it provides its contents when it is subjected to vibration such as it experiences in transportation. These procedures are suitable for testing containers of any form, material, kind, design of interior packing, means of closure, and any size and weight. They are not intended for determining the response of products to vibration for product design purposes, nor are they intended for tests of products in their operational configuration as other more suitable procedures are available for these purposes.2,3  
1.2 The following methods appear:
Method A1—Repetitive Shock Test (Vertical Motion).
Method A2—Repetitive Shock Test (Rotary Motion).
Method B—Single Container Resonance Test.
Method C—Palletized Load, Unitized Load, or Vertical
Stack Resonance Test.  
1.3 For testing of intermediate bulk containers (IBCs) containing liquid hazardous materials, refer to Test Method D7387.  
1.4 These test methods fulfill the requirements of International Organization for Standardization standards ISO 8318 and ISO 2247. The ISO standards may not meet the requirements for these methods.  
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. Specific precautionary statements are given in Section 6.

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.
