of measurements and such are shown in table 3 1 basis weight 1 plytissues measured in accordance with japanese industrial standard p8124 2 paper thickness 2 plytissues the paper thickness is measured by using a dial thickness gauge u201c peacock g type u201d manufactured by ozaki mfg co ltd under the conditions that are regulated by japanese industrial standard p8111 typically first check that there is no rubbish or dust between the plunger and the measuring pedestal then put down the plunger on the measuring pedestal set the dial of the dial thickness gauge at 0 raise the plunger and put the specimen a facial tissue onto the pedestal of the tester and then put down the plunger slowly and read the gauge at this moment merely the plunger is put on the specimen the measurement is done on one sheet and the mean value of 10 measurements is the paper thickness 3 density calculated by the next formula 4 solution content as mentioned above 5 solution content per volume unit of the paper as mentioned above 6 oil absorbance as mentioned above 7 compound ratio of nbkp measured in accordance with japanese industrial standard p8120 8 crape rate calculated by the next formula a circumferential speed of the drier while manufacturing paper u2212 circumferential speed of a reel circumferential speed of the drier while manufacturing paper u00d7 100 9 tensile strength measured in accordance with japanese.
