Empirically Based Water Condensation and Vapor Clearing Time Calculator for Automotive Lighting Assemblies 2008-01-0489

Drawing from previous studies published in SAE, a software program describes physical progress of water intrusion into or released from a lamp assembly. This program, based on test data, calculates condensation quantity and clearing time. It calculates moisture exchange between a lamp assembly and ambient, considering the moisture contained in the air inside of the lamp and moisture stored on the wall surface or in the materials. This program is applicable to different scenarios, such as initial humidity conditions of a lamp assembly, lamp size, type, venting type and test performance specifications. The significance of the program application in guiding test performance will also be addressed.
