3、mining the bonding permanency of adhesives for sealing the top flaps of fiberboard shipping cases.This method is for use in con-junction with the adhesive bonding permanency test described in ASTM Method D 171 3,Test for Bonding Permanency of Water-or Solvent-Sol-uble Liquid Adhesives for Automatic
4、Machine Sealing Top Flaps of Fiberboard Specimens.The use of board stock of uniform water absorptive-ness is necessary to ensure that comparative re-sults are obtained with adhesives tested for bond-ing permanency.Specimens of fiberboard used for such tests must be within I50 percent of the average

8、imens may be the liner facing mate-rials of the corrugated board stock;or combined corrugated,faced board stock,or solid fiberboard stock.If the linear facing material is used,it should be obtained from the shipping case man-ufacturer rather thn from the assembled case.When corrugated board stock is
