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. Untwist the tape determining the quadrant of rotation needed to straighten it. Adequate safeguards for personnel and property shall be employed in astn these tests. With assembly at room temperature, totally immerse the specimens vertically in a speci? Unwind sufficient tape so that the free end of the tape can attach to the upper jaw of the machine.
The maximum force recorded is de?
If it is necessary to trim the specimens due to the machine or jaw width limitations, take extreme care since hand trimming has the potential to materially affect the test results. A When referee testing is involved, use an average of 5 determinations wherever 1 or 3 are speci?
Prepare two test specimens by spirally 1d000 a layer of tape on the brass rods using 2. If necessary, adjust the angle of the rod by successive trials until the proper angle for the particular tape is obtained. Follow the procedure described in D — 10 wind-up roll that can be used to either manually or automatically unwind the roll of tape.
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? This unwind force is useful as a measure of the effects of natural, shelf aatm accelerated aging, and the unwind force determined at the fast rate of removal is useful as a measure of the ease of unwinding in mechanized or hand dispensers.
Bond Strength After Solvent Immersion. Check with the level to ensure that the wrapped specimen is horizontal. B Minimum and maximum values are also occasionally required when average values are reported.
Method A—For Class 1 Tape Check the zero reading on the qstm. It is acceptable to use as the horizontal platform a bench or the?
It is advisable to cover the test chamber with thermal insulation in order to minimize internal temperature? Secure one end of the specimen strip of tape near one end of the rod.
The electrodes which are a part of the test?

By suitable means, attach this d100 to a scale or other measuring device. Firmly clamp the tape between the electrodes taking great care to avoid contact between the hands and any tape surfaces between electrodes.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? D — 10 ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. After removal from the? After this application of pressure, cut the tape to a width of 13 mm 1? Committee D09 has identi?
The apparatus must be capable of providing smooth, uniform jaw movement during testing, and the rate adjustable in increments necessary to produce strain rates that are speci? D — 10 conditions for a minimum of 24 h before testing. Tighten the movable grip?
atm At the end of this period, measure the length of the? One arrangement, suitable for testing a number of tapes at the same time, has several rows of electrodes mounted on the inside of the cover of the humidity chamber as shown in Fig. Increased air pressure raises the gripping force to accommodate materials that are often difficult to hold in other types of grips.
