The fittings, doors, windows andthe construction ofthe body ofanautomotive vehicle shall besuchthat there is no ingress of water into itduring rainy season. This standard gives procedure to conduct water proofing test on automotive vehicles by creating test conditions similartothose inrainy seasontowhich anautomotive vehicle is likelytobeexposed. This procedure intendstoprovide forauniform practice toassesswaterproofing ofvehicles. The standard was first published in 1986. This revision has been taken up to update the testprocedure and to include various terms used for clear interpretation, togive details oftest facility indicating types ofnozzles used, distance between them, flowrate andpressure ofwater, etc,used during thetest. !S 11865:2006 Indian Standard AUTOMOTIVE VEHICLES — METHOD OF CONDUCTING WATERPROOFING TEST (First Revision) 1 SCOPE pattern for maximum surface coverage as shown in Fig. 1(A)andFig. 1(B).Thepitchofthesenozzlesshall This standard prescribes the procedure forconducting be 400 mm in both the directions.
