Place the tape in the center of the drums with the edges parallel to the scribed lines. Project an imaginary axtm representing the end of the tab onto the horizontal platform.
Method A—Balance Method Apply the specimen so that a mm 5-in. Clamp the roller assembly in the lower jaw of the tension testing machine. After removal from the?
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Measure the width perpendicular to the edges in mm in. Discard the gauze after each cleaning step. Place the tape on a smooth clean surface, adhesive side up, or suspend it from one astj in free air.
Remove the weight dd1000 cut the tape at point D by tearing against the blade edge, taking care not to cut the lower layer of tape.
Do not use them in the vicinity of open? Rods of other diameters are acceptable if agreed upon between the manufacturer and the purchaser. It is essential that the test apparatus, and all associated equipment electrically connected to it, be properly designed and installed for safe operation.

Calculate and record all values, and the median resistance of the? Use tape 14 mm 9? Run d10000 approximately 10 m 10 yd for each test. It is acceptable to use double-coated tape to reinforce gripping, by applying a xstm piece of tape on each side of the? When thermosetting tapes are used, cure the assembly as described in Use clean steel plates. It is advisable to cover the test chamber with thermal insulation in order to minimize internal temperature?
D — 10 conditions for a minimum of 24 h before testing.
If the strip of tape is wider than 14 mm 9? This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Xstm specimens that are the width of the tape as received if possible. Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend.
These test methods are similar to IEC —3, but may differ asm in some details. They must be stored in closed containers, and it is imperative to clean apparatus in a well-ventilated area. Recommended meter is any quality, high resistance, solid state measuring instrument, with a suitable resistance range, as described in Test Methods D, that will impress the required potential on the sample and cover the required e1000 range.
If the burner is physically removed, the air? It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Compare with the prescribed time of failure. The unwind force for widths other than 25 mm 1 in. For specific hazards see Section 3. V1000 sure no air bubbles are trapped.
Measure to the nearest 1 mm 1? Apparatus and Materials Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
Unwind Aastm at Low Temperatures. Make all measurements in air.
Conduct one test on each roll. Zero the testing machine to compensate for the weight and frictional drag of the test? In radius, In diameter,?
From this tape material, prepare specimens as required in the individual ashm methods. Satisfactory means of obtaining this relative humidity are described in Practice D The usefulness of this test method is primarily for speci?
After unwinding is completed, take the reading of the length sensor.
