Significance and Use4.1 The interior dimensions are important properties in thegeneral construction of a box, and accurate methods ofmeasurement are required for research work, routine control,and acceptance testing for conformance to specifications. Forcontainers to carry and protect the
10、ir contents effectively andefficiently, the containers must be of proper and uniform size.This method involves a degree of human judgment andassumes careful and accurate placement and reading of speci-fied apparatus.4.2 Method A, Measuring Lot of Boxesdetermines if a lot(i.e., production run) is wit

Apparatus5.1 Measuring Equipment, consisting of two flat metalplates mounted on each end and at right angles to a telescopin
16、gspacing bar (Fig. 1).5.1.1 Metal Plates The metal plates shall be not less than316 in. (4.76 mm) thick and shall have length and widthdimensions of 4 by 3 in. (102 by 76 mm) with a maximumsurface roughness height of 64 in. (1.63 m), in accordancewithANSI B46.1.All sharp edges shall be relieved and
17、cornersshall be rounded with approximately14-in. (6.35-mm) radius.The plates shall be mounted firmly at each end of thetelescoping bar and must be parallel to each other within 0.02in. (0.5 mm).5.1.2 Spacing Bar Provision shall be made for adjustingand locking the spacing bar at the linear distance
18、between thetwo plane surfaces. If the spacing bar incorporates a built-inscale for convenience in reading measurements, it shall beaccurate to one half of the minimum measurement unit; that is,if the minimum measurement unit is116 in. (1.6 mm), theinstrument must be accurate to132 in. (0.8 mm), etc.
19、5.2 Size and Weight RangesCorrect weight of the mea-suring instrument is important. Weights of instruments forthree basic size ranges shall conform to the specifications givenin Table 1.6. Sampling6.1 Select specimens at random in accordance with goodpractice or sampling procedures.7. Test Specimens
20、7.1 Method A, Measuring Lot of Boxes7.1.1 In no instance shall fewer than five specimens bemeasured and taken as representative of the lot.7.1.2 For large lots, a formal sampling plan is advised.Application of Practice D585 is suggested.NOTE 1Acceptance or rejection of a production lot should be bas
21、edon a sampling plan mutually agreeable to both the supplier and user of theboxes as indicated in a specification, contract, or other agreement.8. Conditioning8.1 Condition the boxes for measuring in accordance withPractice D685 and Practice D4332.9. Procedure9.1 For each box to be measured, set up
22、and square the boxin the normal manner and place it on a smooth, flat surface withthe bottom flaps folded into position but not secured by anytype of sealing device or preparation.9.2 Measuring Length Measure the length dimensionbetween the two end panels, holding the instrument as close aspossible
23、to the side panel opposite the manufacturers joint.Place one end of the instrument firmly against one end of thebox and adjust the other end until it is just tight enough that,when released with the box inclined so that the side panelclosest to the instrument is at an angle of approximately 65 tothe
24、 horizontal, the instrument will slide slowly down the sideof the box and come to rest at the bottom. When the correctextension of the instrument has been obtained, lock it, and ifequipped with a self-contained scale, read the distance betweenthe faces directly. If the instrument does not incorporat
25、e ascale, remove the instrument from the box and measure theNOTE 1The unit shown covers the middle range from 10 to 18 in. (254 to 457 mm).

Correct extension and measurement reading is
29、 obtainedin the same manner as previously described for length.9.4 Measuring Depth:9.4.1 Measure the depth dimension between the end flapswhen these have been folded into position and at the endopposite the manufacturers joint. Place the instrument, withthe spacing bar extended to a point less than
30、the actual depth ofthe box, in an upright position approximately in the center ofthe bottom end flap and close the corresponding top end flapover it. Extend the instrument while in this position until thetop end flap is brought into a horizontal position. This may bechecked by closing the top outer
31、flaps over the inner flap withthe instrument locked in position and placing a straightedgeacross the outer flaps at right angles to the length dimensionand overlying the instrument. The proper extension has beenreached when the outer flaps exhibit a slight crown as indicatedby light showing between
32、the straightedge and the outer flapsfor a distance of about 1 in. (25.4 mm) from the flap score.Then, remove the instrument from the box and measure aspreviously described.9.4.2 A second method for measuring depth consists ofmarking a line on the long flap inner scoreline center. The longflap is ben
33、t to about a 45 angle to the side of the box, whilemarking the scoreline center with a ballpoint pen or sharppencil. Place the box gage under the folded-down inside flapand against the container side wall. The edge of the 4 by 3-in.(102 by 76-mm) plate shall be just visible where the cut edgeof the
34、inner flap contacts the line previously drawn on thescoreline center. Extend the instrument until the top of theinner flap coincides with the line. Then remove the instrumentfrom the box and measure as previously described.9.5 Method A, Measuring Lot of BoxesMake one mea-surement of each dimension o
35、n each specimen. If any mea-surement is outside of specified tolerance, then re-measure thatbox specimen using Method B to determine the final test result.9.6 Method B, Measuring Single BoxMake one measure-ment of each dimension, knock box down. Repeat this proce-dure four more times, setting box up
36、 again and measuring eachdimension once for each repeat cycle, obtaining a total of fivemeasurements for each dimension.10. Calculation10.1 Method A, Measuring Lot of Boxes10.1.1 To determine the test result on each dimension for aset of specimens, use the individual measurements of each box.10.2 Me
37、thod B, Measuring Single Box10.2.1 The test result for each dimension is the average ofthe five measurements taken on the box for that dimension.NOTE 2Individual measurements tend to hae more variation than theactual dimension of the box. Thus a single high or low measurement doesnot necessarily ind
38、icate a box is outside of specified tolerance. Averaginga minimum of five measurements is intended to reduce measurementvariation and provide a better indication of true box size.11.

Precision and Bias12.1 The precision statement4(see Practice E691) is basedon data developed from a round robin box measurement testusing regular slotted containers
42、 (RSC). The test was conductedby ten laboratories or individuals familiar with the use of thebox gage. The test specimens consisted of four different sizeboxes ranging in size to use all three box gages. The repeat-ability concerns the variability between single independent testresults obtained with
43、in a single laboratory. The reproducibilityconcerns the variability between average test results obtainedin different laboratories. The precision of the method forregular or special slotted containers is shown in Table 2.12.2 There is no bias because the value of the interiordimensions is defined on
44、ly in terms of this test method.13.
