To allow full compliance with international regulations MLC (2006) and ILO 178 including local regulations like the Norwegian Drinking Water Regulations it is essential to do some additional testing not included in the CMT Potable Water Test Kits.
Those tests will be provided with options from CMT. It is also essential to have a proper record keeping which can be done with the CMT log book provided with the manual in the standard kit.
International regulations further specify that a trained person needs to be on-board each vessel or rig to perform the tests. CMT does provide different seminars ensuring proper qualification. A certificate will document the respective qualification. You will find our seminar program at the end of this catalogue.
Equip your Water Test Kits with the Handheld Colorimeter to measure true Colour more effectively. True colour is caused by dissolved compounds in water and can natural, artificial or both.
Apparent colour, caused by both dissolved and suspended solids, is measured in Platinum-Cobalt units (PCU). The AWWA recommends < 15 PCU. CMTs Colorimeter makes it easy to measure with only one small device. Not only size is an advantage over chemicals, it is also more accurate.
The Chlorination Test Kit will enable the operator to complete the disinfection process correctly and maintain chlorination levels.
The chlorine HR test is used to check that chlorine has been dosed to the correct levels and the starch/ potassium iodide strips are used to make sure the chlorine has been neutralised. The chlorine LR test is then used to check that chlorine reserves are kept to the maximum permitted level of 0.5ppm.
The pH test strips are used to check that pH values are between 5 -6 pH during chlorination. The pH should be carefully monitored because acidic pH solutions below 4 can cause the release of chlorine gas which is toxic. When using chlorine as a disinfectant it is important that the pH be 5 - 6 to improve its bacteria reducing properties.
Conductivity is an indirect measurement of total dissolved solids. Typical value (approximately) for untreated distillates is 50 µS/cm. Water from shore sources should have around 500 µS/cm. Seawater has about 50,000 µS/cm. Therefore a high conductivity could be an indication for seawater ingress. A too low conductivity value should trigger evaluation of corrosive processes in the piping and existing of heavy metals due to corrosion.
Ideal pH value depends on the materials used. A pH value above 8 does not allow effective water disinfection with chlorine and gives evidence that self produced water may not be re-mineralized adequately. Further assessment of water quality should be performed.
