Limits are given for impurities commonly present in the product. Depending on the raw m
37、aterial and the manufacturing process other impurities may be present and, if so, the user and when necessary relevant authorities shall be notified. Users of this product should check the national regulations to clarify whether it is of appropriate purity for treatment of water intended for human c
38、onsumption, taking into account raw water quality, required dosage, contents of other impurities and additives used in the product not stated in this product standard. Limits have been given for impurities and chemical parameters where these are likely to be present in significant quantities from th
39、e current production process and raw materials. If the production process or raw materials leads to significant quantities of impurities, by-products or additives being present, the user shall be notified. 4.2 Composition of commercial product The sodium permanganate is usually available in a concen
40、trated solution with a concentration within the range of mass fraction of 20 % to 40 %. The concentration of sodium permanganate solution shall be equal to or greater than the manufacturer specified value. 4.3 Impurities and main by-products The content of manganese dioxide (insoluble matter) shall
41、be no more than a mass fraction of 0,055 %. NOTE The product can contain fluoride or hexafluorosilicate. At typical levels of dosing, the added fluoride would be less than 40 g/l. 4.4 Chemical parameters The content of chemical parameters shall conform to the requirements specified in Table 2. Table

43、mpling 5.1.1 General Observe the general recommendations of ISO 3165 and take account those of ISO 6206. 5.1.2 Sampling from drums and bottles 5.1.2.1 General 5.1.2.1.1 Mix the contents of each container to be sampled by shaking the container, by rolling it or by rocking it from side to side, taking
44、 care not to damage the container or spill any of the liquid. 5.1.2.1.2 If the design of the container is such (for example, a narrow-necked bottle) that it is impracticable to use a sampling implement, take a sample by pouring after the contents have been thoroughly mixed. Otherwise, proceed as des
45、cribed in 5.1.2.1.3. 5.1.2.1.3 Examine the surface of the liquid. If there are signs of surface contamination, take samples from the surface as described in 5.1.2.2. Otherwise, take samples as described in 5.1.2.3. 5.1.2.2 Surface sampling Take a sample using a suitable ladle. Lower the ladle into t
46、he liquid until the rim is just below the surface, so that the surface layer runs into it. Withdraw the ladle just before it fills completely and allow any liquid adhering to the ladle to drain off. If necessary, repeat this operation so that, when the other selected containers have been sampled in
47、a similar manner, the total volume of sample required for subsequent analysis is obtained. 5.1.2.3 Bottom sampling Take a sample using an open sampling tube, or a bottom-valve sampling tube, suited to the size of container and the viscosity of the liquid. When using an open sampling tube, close it a
48、t the top and then lower the bottom end to the bottom of the container. Open the tube and move it rapidly so that the bottom of the tube traverses the bottom of the container before the tube is filled. Close the tube, withdraw it from the container and allow any liquid adhering to the outside of the
49、 tube to drain off. When using a bottom-valve sampling tube, close the valve before lowering the tube into the container and then proceed in a similar manner to that when using an open sampling tube. 5.1.3 Sampling from tanks and tankers From each access point, take samples as follows: a) from the surface of the liquid, using a ladle as described in 5.1.2.2; b) from the bottom
