ASTM D2148Standard Test Methods for Bondable Silicone Rubber Tapes Used for Electrical Insulation
ASTM D2148 is a test standard that for testing bondable silicone rubber tapes, which form a sealed structure either with the application of heat (and pressure if needed) or by the process of auto-adhesion (self-fusing).
Before conducting ASTM D2148, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
