ASTM D4727/D4727M-22(Specification)
Standard Specification for Corrugated and Solid Fiberboard Sheet Stock (Container Grade) and Cut Shapes

ABSTRACT
This specification covers corrugated and solid fiberboard sheet stock (container grade) and cut shapes intended for use mainly in the fabrication of boxes and interior details (for example, pads, sleeves, liners, partitions, and die-cut sheets). Covered in this specification are three classes (domestic and domestic/fire retardant, weather resistant and weather resistant/fire retardant, and water and water-vapor resistant and water and water-vapor resistant/fire retardant) of corrugated fiberboard and two classes (domestic and domestic/fire retardant, and weather resistant and weather resistant/fire retardant) of solid fiberboard, with a variety of grades reflecting the varied performance levels of the fiberboards. Corrugated fiberboards shall be manufactured with two, three, or four facings for single-, double-, or triple-wall varieties, respectively, with each facing separated by and securely adhered to the corrugating medium of any suitable fiber. Solid fiberboards, on the other hand, shall be manufactured from plies securely and continuously laminated together. The facings of corrugated fiberboards and plies of solid fiberboards shall conform to the requirements specified. Tests for thickness, basis weight, puncture resistance, ply separation, bursting strength, flame spread, specific optical density, and edge crush shall be performed and shall conform to the requirements specified.
SCOPE
1.1 This specification covers fiberboard primarily used for the fabrication of boxes and interior details such as pads, sleeves, liners, partitions, die-cut sheets, etc.  
1.2 The performance of fiberboard boxes is largely dependent on the paper components from which they are fabricated and, in the case of corrugated boxes, on the flute structure as well. Therefore, a variety of grades reflecting varied performance levels are specified.  
1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. See IEEE/ASTM-SI-10 for conversion of units.  
1.4 The following safety hazards caveat pertains only to the test portion, Sections 8 and 9, of this specification: 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.

ASTM D4169-22(Practice)
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.

ASTM D880-92(2021)(Test Method)
Standard Test Method for Impact Testing for Shipping Containers and Systems

SIGNIFICANCE AND USE
5.1 The impact test has been found useful in laboratory simulation of impacts such as those encountered in manual and mechanical handling and transportation. The impact test simulates some types of shocks that could occur in the handling of packages or shipping units and helps evaluate the ability of the package to protect the contents against these shocks. The test may also permit observation of progressive failure of a package and damage to the contents.  
5.2 The test results within a given laboratory using this test method may be useful for evaluating and comparing packages. However, because of the variability of test machines that have been used in the past, especially the impact surface (backstop), it has been found that interlaboratory correlation of test results has been poor.  
5.3 These procedures are not intended to simulate rail car coupling environment. Refer to Test Method D4003 and Test Methods D5277.  
5.4 This test method fulfills the requirement of ISO 2244.
Note 1: ISO 2244 may not meet the requirements for this test method.
SCOPE
1.1 This test method covers two procedures for conducting impact tests on loaded containers or shipping units (pallet loads), as follows:  
1.1.1 Procedure A, to test the ability of a container or shipping unit to withstand impacts, and  
1.1.2 Procedure B, to test the ability of a container or shipping unit or interior packing, or both, to provide protection to the contents, when subjected to impacts.  
1.2 Either of these two procedures may be used to evaluate different designs of containers of the same size and carrying the same load. These procedures are suitable for testing various types of containers such as boxes, crates, barrels, drums, kegs, bags, sacks, or pails made of various materials or combinations of materials and for shipping units such as pallet loads or palletized units.  
1.3 The procedures described in this test method are particularly suitable for testing large or heavily loaded containers.  
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. Specific precautionary statements are given in Note 1 and Section 7.  
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 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.
