MEPC 49/22/Add.2ANNEX 13Page 20Contaminant and colour testFigure 5 - Diagrammatic arrangements of test facilities2.2.6 The 15 ppm Bilge Alarm should undergo contaminant and colour tests as follows:.1 the 15 ppm Bilge Alarm should be run on a mixture of clean water and 10 ppmTest Fluid “B” and reading noted;.2 the water supply should be changed from 10 ppm Test Fluid “B” and clean waterto 10 ppm Test Fluid “B” and water contaminated with iron oxide in aconcentration of 10 ppm;.3 any shift in the 15 ppm Bilge Alarm reading should be noted. The reading shouldbe within the accuracy limits specified in paragraph 2.2.1;.4 the procedure specified in .2 and .3 above should be repeated with iron oxideconcentrations of 50 ppm and 100 ppm respectively;.5 the 15 ppm Bilge Alarm should be run on a mixture of clean water and 10 ppmTest Fluid “B” and its reading noted;.6 the water supply should be changed from clean water to very salt water (a solutionof 6% common salt with clean water);.7 any shift in the 15 ppm Bilge Alarm reading should be noted. The reading shouldbe within the accuracy limits specified in paragraph 2.2.1; and.8 sufficient water should be available in the mixing tank to ensure an effective testof not less than 15 min.I:\MEPC\49\22-ADD.2.DOC
