1.1 These test methods cover procedures for testing pressure-sensitive adhesive-coated tapes to be used as electrical insulation. These tapes are classified as follows:
1.1.1 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, |
| Polyamide films, |
| Polyimide films, and |
| Combinations thereof. |
1.1.2 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. |
