F11500 - SEMI F115 - Test Method for the Determination of Metallic Elements Present on Wetted Surfaces of Ultra High Purity Chemical Delivery Systems and Components Revision:SEMI F115-0220 - Current org in July 2001This Document defines a test method for determining metallic elements present on the wetted surfaces of ultra high purity (UHP) chemical delivery systems and components. This Test Method is applicable to UHP chemical delivery systems and components. Examples of test samples include valves, regulators, filters, mass flow controllers, tubing, weld fittings, and face seal fittings. This Test Method could also be used to determine the contamination
