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 test
9、ing for conformance to specifications. Forcontainers to carry and protect their 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 Met
10、hod A, Measuring Lot of Boxesdetermines if a lot(i.e., production run) is within specified tolerance for eachdimension (length, width, and depth). A minimum of fivespecimens are measured. The test result for each dimension isthe individual measurements of that dimension on all speci-mens. If any tes
11、t result is outside of a specified tolerance, thatbox specimen should be re-measured using Method B todetermine final test results.4.3 Method B, Measuring Single Boxesdetermines if oneparticular box is within specified tolerance for each dimension.The test result for each dimension is the average of
12、 allmeasurements of that dimension.5.

15、 C700, West Conshohocken, PA 19428-2959, United States.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 s
16、harp edges shall be relieved and 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 sp
17、acing bar at the linear distance 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
18、accurate to132 in. (0.8 mm), etc.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 samp
19、ling procedures.7. Test Specimens7.1 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
20、of a production lot should be basedon 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 D 685 and Practice D 4332.9. Procedure9.1 F
21、or each box to be measured, set up 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
22、the instrument as close aspossible 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
23、 an angle of approximately 65 tothe 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
24、 the instrument does not incorporate ascale, remove the instrument from the box and measure thedistance between the outer surfaces of the plates by means ofa separate scale accurate to132 in. (0.8 mm).9.3 Measuring Width Measure the width dimension of thebox between the two side panels, holding the
25、instrument asclose as possible to the end panel opposite the manufacturersjoint. Correct extension and measurement reading is 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 posi
26、tion and at the endNOTE 1The unit shown covers the middle range from 10 to 18 in. (254 to 457 mm). Rounded knurled knob at upper left is lifted to set gage to thenearest full unit measurement below box dimension. Knurled knob at lower left is used to lock extension rod in place. Adjusting nut at rig

29、ended to a point less than 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 bechecke
30、d by closing the top outer 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 indicat
31、edby light showing between 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
32、center. The longflap is bent 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 visibl
33、e where the cut edgeof the 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-s
34、urement of each dimension on 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
35、 more times, setting box up 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 measu
36、rements of each box.10.2 Method 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 measurem
37、ent doesnot necessarily indicate 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 E 691) is basedon data developed from a round robin box measurement testusin
41、g regular slotted containers (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 independe
42、nt testresults obtained within 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 inte
43、riordimensions is defined only in terms of this test method.13.
