Calibrate the gauge for the actual load exerted by the presser foot. Use only full rolls of tape.
Polyethylene d0100 polyester films. Place the tape in the center of the drums with the edges parallel to the scribed lines. Construct each specimen from two strips of tape fastened together to form a mm 1? Measure the adhesion of each specimen in accordance with Unwind Force at Low Temperatures.
There shall be no obstructions in the path between the platform and the spindle. Make a minimum of three acceptable determinations. Take care to ensure that the adhesive does not contact the hands or other foreign object. The adhesion property is also important in determining the uniformity of quality. Do not remove any outer layer. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

Place the specimens on clean blotting paper or towel for 30 min, then determine the breaking force to break the bond in accordance with Section 42, using clamp-type holding? D — 10 conditions for a minimum of 24 h before testing. Also, the solvent action is at room temperature, while often hot solvent action occurs in application. Permission rights to photocopy the standard may also be secured from the ASTM website www.
Use specimens that are the width of the tape as received if possible. Remove each specimen from the roll in accordance with 5. Approved October 15, 1 Revised NOTE 5—A high response speed in the recording system is desirable, particularly when relatively high strain rates are employed.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
Position the roll and length sensor so that the sensor is in contact with the circumference of the roll and the leading end of the roll is directly under the sensor. After conditioning the roll of tape, place it on a table in a vertical position. Immediately release the tab. Attach a weight as required by the nominal thickness to the lower end of the tape.
For xstm of 0. Place the tape on a smooth clean surface, adhesive side up, or suspend it from one end in asgm air. Close the caliper jaws slowly so as to just touch the sides of the tape roll. Wrap three strips of metal foil not more than 0.
The serrated surface is recommended for stronger materials that require the greatest gripping action. Conduct one test on each roll. If you asrm that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
The top grip holds the roll of tape so that it can unwind freely and then spool onto the new roll which is attached to the motorized fixture. Measure the width perpendicular to the edges in mm in. The driven 7 The sole source of supply of the variable-speed unwind machine meeting these requirements known to the committee at this time is Chemsultants International, Hamilton Drive, Mentor, OH Run off approximately 10 m 10 yd for each test.
