Standards

Rubber-Insulation Standard Withdrawn. Under date of August 11, 1939, the American Standards Association issued notice that on recommendation of sectional committee C8, “Insulated Wires and Cables,” the American Standard entitled “Specifications for Class A 30 Per Cent Rubber Insulation for Wire and Cable for General Purposes,” C8.4 (1936) has been withdrawn. The action of the ASA is based on the fact that the standard had dropped out of general use, having been displaced by C8.17 “Class OA 30 Per Cent Rubber Insulation for Wire and Cable for General Purposes.”
