This specification outlines the requirements for a standard ultrasonic welding test sample for thermoplastics and its welding and testing.

This standard makes use of both the International System of Units (SI) and U.S. Customary Units. The measurements are not exact equivalents; therefore each system must be used independently of the other without combining in any way. The standard with the designation G1.2M:1999 uses SI Units. The standard with the designation G1.2:1999 uses U.S. Customary Units. The latter are shown in appropriate columns in tables and figures, and within parentheses ( ) when used in the text.
