Record the burning time for each asym and calculate the average burning time. Approved October 15, 1 Revised The testing machine shall have two clamps with centers in the same plane, parallel with the direction of the motion of the stressing clamp, and so aligned that the clamps will hold the specimen entirely in the same plane. Vinyl chloride and co-polymers, Vinylidene chloride and co-polymers, and Polyethylene and co-polymers.

If you feel 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. Method B—For Class 2 Tape By measuring the insulation asrm of tape samples in contact with speci? If necessary, adjust the angle of the rod by successive trials until the proper angle for the particular tape is satm. After removal from the? See also Table 1.


With assembly at room temperature, totally immerse the specimens vertically in a speci? After all traces of solvent evaporate, wipe the surface of the panel with a clean dry piece of surgical gauze.

Check with the level to ensure that the wrapped specimen is horizontal. Operate the machine from the scale. Also, the solvent wstm is at room temperature, while often hot solvent action occurs in application. Let it relax for about 2 min or more. These tapes are classified as follows:. Qstm is limited in that adhesion to itself or backing only are considered, while in use tapes are generally adhered to various surfaces.

The rubber-coated surface awtm of value with materials that tend to be weakened by pinching at the edge of the jaw face.

ASTM D1000

Vinyl chloride and co-polymers. Originally approved in Zero the testing machine to compensate for the weight and frictional drag of the test?

Thermosetting properties are measured by a bond separation test and are reported as the time to failure of a heat-cured adhesive-to-adhesive bond under a prescribed load at a speci? Use specimens that are the width of the tape as received if possible. Method A—Fast Rate of Removal Yards per roll 5 weight of roll less core 3 length of specimen, in. Puncture resistance is important because of the possibility that objects with irregular surfaces or relatively sharp contours aatm as wire or laminate will be present in the application and have the potential to cause a rupture in the tape.


Increase the voltage from zero to breakdown at a uniform rate of 0. The wstm of drum jaws makes it extremely difficult to identify accurately the gauge length between jaws.

The free-turning wheel or drum of the assembly shall? The unwind force for widths other than 25 mm 1 in.

Run off approximately mm 1 ft of tape for each determination. Breaking Strength and Elongation at Room Temperature.

Discard any damaged or crushed edges. 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?

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. D — 10 FIG. If a value for measurement is followed asstm a value in inch-pound or English units in parentheses, the second value may only be approximate and is for information only. These tapes are classified as follows:
