This standard makes use of both U.S. Customary Units and the International System of Units (SI). The measurements may not be exact equivalents; therefore, each system must be used independently of the other without combining in any way. The standard with the designation D10.6:2000 uses U.S. Customary Units. The standard designation D10.6M:2000 uses SI units. The latter are shown within parenthesis ( ) or in appropriate columns in tables and figures.

¹ Where pipe is used in this document, it refers to both piping and tubing.
