The interior 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 containers to carry and protect their contents effectively and efficiently, the containers must be of proper and uniform size. This method involves a degree of human judgment and assumes careful and accurate placement and reading of specified apparatus.
Method A, Measuring Lot of Boxes8212;determines if a lot (i.e., production run) is within specified tolerance for each dimension (length, width, and depth). A minimum of five specimens are measured. The test result for each dimension is the individual measurements of that dimension on all specimens. If any test result is outside of a specified tolerance, that box specimen should be re-measured using Method B to determine final test results.
Method B, Measuring Single Boxes8212;determines 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.
1.1 This test method covers the determination of the interior 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 and health practices and determine the applicability of regulatory limitations prior to use.
