ASTM D1000 – Standard Test Methods for Pressure-Sensitive Adhesive-Coated Tapes Used for Electrical and Electronic Applications
ASTM D1000 – This test method covers several test methods for the characterization of tapes used in electrical applications. These test methods cover procedures
for testing pressure-sensitive adhesive-coated tapes to be used as electrical insulation.
*** These tapes are classified as follows:
Class 1—Non-elastomeric backings made from materials such as
Paper, flat or creped,
Fabric, uncoated or coated,
Cellulose ester films,
Polyethylene terephthalate (polyester) films,
Fluorocarbon polymer films,
Composite filament films,
Polyimide films, and
Class 2—Elastomeric backings that are characterized by both high stretch and substantial recovery.
These backings are made from materials such as ;
Vinyl chloride and co-polymers,
Vinylidene chloride and co-polymers, and
Polyethylene and co-polymers.
Pressure Sensitive Adhesive tapes are sold in rolls. In automated manufacturing environments, these rolls are loaded into a machine for assembly.
The unwind force is an important specification because it may affect the machine behavior.
Unwind force also plays a role in logistics environments where packages are being wrapped, taped and shipped off to their destination.
The unwind force at the specified rate gives information on the combined effects of the interlayer adhesion in the roll and of the physical condition of the backing
and adhesive mass.
This unwind force is useful as a measure of the effects of natural, shelf or 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.
A tape width of 25 mm (1 in.) is considered optimum for this test method.
The unwind force for widths other than 25 mm (1 in.) is not always proportional to the width.
A motorized system must be used to unwind the tape, as demonstrated in the video.
The speed of the unwind must be 150 ft/min.
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.
PARSROS offers several types of grips and fixtures which will enable you to perform a variety of lap shear tests
that are accurate and repeatable.
