Salinty Test

a. Reference Standard:

1. Japan Road Association, Painting Manual for Steel Highway Bridges (2014 Edition)

2. ISO 8502-5 Measurement of Chloride on Steel Surface prepared for painting ( Ion Detection Tube Method)

b. Scope of Application

This is to conduct a field test for Chloride Ions present in during the transportation in the sea of the steel structures. 

c. Apparatus and Materials 

• Chloride ion detection tube ( 201SA, 201SB, 201SC)
• Deionized Water (Purified Water ) 150 ml
• Cotton Gauze 330x30 cm
• Rubber Gloves 
• Masking Tape  20mm thickness 
• Measurement Tape 
• Poly beakers 100ml, 250ml capacity

d. Procedure

Test area is approximately 50x50cm approximate the shape depending on the size and shape then apply masking tape.

Figure 3: Soak the cotton gauze in the larger beaker and wipe horizontally taking out all the dirt. 

Figure 4. Wipe vertically covering all the area until totally cleaned.

Figure 5. clean the gauze in the 100ml beaker to collect all the dirt and foreign material. Repeat 3-5 times

Figure 7.: Combine the 50ml and 100ml 

Figure 8.: Immerse on the end of ion detection test tube in the test sampling water for chlorination.

Figure 9.: Observe the result by chloride ion detection tube. Unit of cholride ion concentration is ppm

Figure 10: Observe for 2-3 minutes to collect the result of the test

Figure 11: Record the result of the test. Salinity Test should marked pass if the ppm is less than 100ppm
