is a trade name for a class of chemicals (known as Chlorofluorocarbons or CFC's) used as a refrigerant in air conditioning systems.

How should I take my forearm circumference measurement? In order to take your forearm circumference measurement, you should tense your arm muscle and measure around the thickest part of your forearm, as pictured.
Begin with the inside back. Measure from side to side first (always!) and then up and down. Allow an extra 2 to 3 inches for extra padding and folding under. Next, measure the arms. The fabric runs down the arm, so measure along the top for your first measurement. When measuring at the bottom, you need only allow for what is visible. A âpullâ (scrap of fabric) will be sewn to the bottom to allow for pulling and stapling.
