The weight of the board shall thenbe caloulaked on the basis of pounds per1000 square feet.

4.6.4 Puncture rssiutunce. The test shallbe made on specimens, 12 by 12 incbs (orequivalent area), cut from sound, undam-aged, and unprinted portions of the boxes.One specimen shall be taken from each ofthe sample boxes in a lot. Specimens shallbe conditioned in the atmosphere describedin 4.6.1 for a period al at least 24 houm.The equipment to be used for the puncturetest is described in TAPPI method T803-M-50. Four pun.oture teat readings shall bemade on each apernmen in the followingmanner: One test shall be made so thatthe edge of the punature point whioh isin the plane of the punoture arm, is perpm-dicuhw to the Corrugation of the fiber-board, and one test shall be made so thatthe edge of the puncture point is parallelto the comugatione of the fiberboaml. Suchteats shall be made from bobh sides of thespecimen. Results of the four puncture testsshall be averaged h determine the test val-ue of the specimem.

4.6.5 Wtort column crush determination.The tests shall be made on specimens 1.25* 0.06 inch high, -by 2 & O.O3 inch wide(with the flutes parallel to the 1.25 inch di-mension), three from eaoh of the samplebo- in the lot. The specimen shall be cutwith a sharp n~set, hollow-gror nd, tablesaw blade. The bearing surfac ? of the-men ehd be parallel to each other andperpendicular to the axk$ of the flutes. Eachloading edge shall be dipped in a pan con-

t4SiniU molten pvaffin (melting point 126°F. approximately) to a depth of 1/4 inchuntil the wax visibly begins to migrate be-yond tihe l/4-inch dip aone-usually about 3seconds. (Hotplate texnperatu=170° to180”F.; liquid wax temperatur%156° to166”F.) The wax should impregnate thespecimen but not migrate appreciably be-yond the l/4-inoh dip zone. (If excessivelyfast migration is encountered, reduce thetemperature of the wax.) After dipping,each edge shall be blotted momentarily onpaper toweling which reeta on a hotplatemaintained at 1700 to 160°F. to removeexcess paraffin from the loading edges,

Note-: An alternative to dipping in to touch themen ~ _ ● PIU~fi*ti=ted pad,mmh aa paper toweling, which redo on a hot-plata maintained at 170° to 180° F. The paraffinmigratea from the pad into the specimen. Al-though this method of impregnation generallyrequires a longer time than dipping, it of ferubetter control of the depth of the zone and ishelpful with epacimena in which rnigratkmproceeds very rapidly.

The specimens shall be prwmnditioned inan atmoaphme of 73° & 3.5”F. and lessthan 35 percent relative humiditi for atkast 24 hours. Prior to testing, specimensshall be conditioned in an atmosphere asdescribed in 4.6.1 for a period of at least48 hours. The above specimens shall be test-ed on an apparatus of the following dwwrip-tion: The apparatus shall consist essential-ly of a compression testing machine (cali-brated in accordance with ASTM E 4, ha-r-ing: (1) an upper and lower platen, one ofwhich may be fixed and the other movable.The surfaces of the platens shall remainsmtih, flat, and parallel to each other with-in one part in 2000 thxwughoti the test. Theplatens shall be so mounted b have n~ morethan 0.002-in& lateral movement.

The 1/2- by l-W*in* f~eof the guide blocks should be in conttd withthe spedmen, -d the 1S/4- by lu’7/lW@face should be in W- with the bottomplaten.

The spec-imens shall be 6 by 10 inches with the @m-rugations perpendicular h the 10-inch di-mension and cut from sound, undamaged,and unprinted portions of the box. The ~imens shall remain submerged for 24 hoursin fresh tap water maintained at a tempera-te of 75° & 5“F. and having a pH value~%ween 5.5 and 8.0.

When the length of the box is24 or more inches, an additional strap shallbe applied at the center.

30.3.5.1.3 Use of tape for cZosure. Whentape is used for closure, a 12 inch tip shallbe applied to each end of the two top andhvo bottom flaps so that 6 inch- of eachstrip is attdmd to the flap and 6 in~hm oftape extends onto the end panel of the box.The strips shall be kxmted adjacent to the
