ASTM D2658-18(2023)

4.1?Dimensions are important properties in the general construction of a box, and accurate methods of measurement are required for research work, routine control, and acceptance testing for conformance to specifications. For packages to carry and protect their contents effectively and efficiently, boxes and interior components must be properly and consistently sized. Correctly dimensioned and well-made boxes can be more easily set up by hand or be erected using automatic equipment. Square boxes (rectangular parallelepipeds) will stack better to accept load and improve stability during storage and shipment.

4.2?Measuring a Lot Quantity of BoxesThis method determines if a lot (that is, production run) is within specified tolerance for each dimension (length, width, and depth as are shown in Practice D5118/D5118M). A minimum of five specimens are measured. The test result for each dimension is the individual measurements of that dimension on all specimens (see 9.3).

4.3?Measuring Single BoxesDetermines if one particular box is within specified tolerance for each dimension. The test result for each dimension is the average of all measurements of that dimension (see 9.4).

1.1?This test method covers the determination of the interior and exterior dimensions of regular slotted or special slotted styles of single-wall corrugated, double-wall corrugated and solid fiberboard boxes.

1.2?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.

1.3?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.
