Water used for industrial water and wastewater analysis Silica ugSiO,/Z Chloride ion ugC1-/ I Sulfate ion ugSO,2-/ I Introduction In order to
10、 prepare the standard of water used for analysis of industrial water and wastewater, this Japanese Industrial Standard has been established by revi- sion of the standard which was established in 1993 on the water for chemical analysis. For the purpose of testing industrial water and wastewater, a lo
11、t of testing methods have been specified, but the fundamental propertites are specified here, because the properties required when testing ordinary water are almost in common. 50 max. 5.0 max. 2.5 max. 10max. 2 max. 1 max. 1 max. 10max. 2 max. 1 max. 1 max. - 1 Scope This Japanese Industrial Standar
12、d specifies the classification, fundamental items, qualities, and testing methods of the water which is to be used for the analysis of industrial water and wastewater. 2 Normative references The standards, shown in Attached table 1, contain provi- sions which, through reference in this Standard, con
13、stitute provisions of this Standard. The most recent editions of the standards indicated in the Attached Table 1 shall be ap- plied. 3 Items in common The items applied in common shall be as follows. a) The items applicable in common for tests shall follow JIS K 0050 and JIS K O101 unless otherwise
14、provided. For the purpose of this Standard, the main terms used in this Standard shall be in conformity with JIS K 0211. b) 4 Classification and qualities Water is classified from Al to A4, and its qualities are as specified in Table 1. This table specifies only the typical items and qualities by wh
15、ich the quality of water is represented, and other items than these may be sumple- mented or selected depending on the test purpose and method (see Remarks 1).

() This is the dire
17、ctly measured value of the output water from a water pu- rifying apparatus using a detector of the electric conductivity meter. (3) When the filter such as a microfilter is directly connected with outlet of an ion exchanger at its final process, and when the output water is di- rectly introduced int
18、o the detector of the electric conductivity meter, the value shall be made 0.01 mS/m (25 “C) or less. Remarks 1 The classified water quality items shown in table 1 are chosen as typi- cal items that express the qualities of water. According to the type and purpose of testing methods for industrial w
19、ater and wastewater, if the qualities other than the specified in table 1 is wanted to be con- firmed, the testing method specified in individual standard shall be followed. 2 The purifying method and serviceability of water from Al to A4 are generally as follows. - Al water is used for washing appa
20、ratus and for the materials to prepare A2 and A3 water. Al water shall be purified through an ion exchanging method or reverse osmosis membrane method at its final process. Alternatively, through the method by which the same quality water can be obtained. - A2 water is used for general tests and for
21、 the materials to prepare A3 and A4 water. It is prepared through the device combined an ion exchange equipment, microfilter, etc. at its final process using Al water.

Alternatively employ the following water. Take A3 or A4 water in a distilling flask, drip potassium perman- ganate solution (30 g/Z) (prepare
31、this solution using potassium per- manganate specified in JIS K 8247) until the solution colors, add 2 ml or 3 rnl of sulfuric acid (1+1) per 1 O00 ml of water, and distil it (the color of potassium permanganate must last until the distillation fin- ishes). Initial distillate (which is equivalent to
32、 about 1/5 of water volu- me kept in the distilling flask) shall be discarded, and about 3/5 of the distillate obtained in the middle stage of the distillation process shall be taken. While the purified water is being kept in a container, the concen- tration of TOC may gradually raise due to contami
33、nation, therefore, it is advisable to use up it as swiftly as possible after purification. 7 Water for test of total oxygen demand (TOD) This shall be dis- solved-oxygen-free water that has been purified similarly to Remarks 6.

35、ities of each item shall be as follows. 5.1 Electric conductivity The test for electric conductivity shall follow JIS K 0552. 5.1.1 Test by continuous measuring method Attach(5) the sample introducing tube(4), which has been washed completely with Al water, to the outlet of water purifying appa- rat
36、us, flow the sample sufficiently for purifying it, control its flow rate and temperature, and introduce directly into the detector of liquid flowing type. If necessary, place a thermostat before the detector. Confirm that the change of flow rate does not affect electric conductivity. Notes (4) The s
37、ample introducing tube is preferably made of soft polyethylene tube or silicone rubber tube. (5) Especially be careful not to make contamination which may come from environment or skin. In order to prevent the contamination from skin, it is preferable to use rubber gloves (no dusting powder) which a
38、re for surgical operation and are specified in JIS T 9107. a) measurement Measurement shall be as follows. i) Follow 4 . 1 in JIS K 0552. 5 . 1 . 2 Test by intermittent measuring method This method shall be applied to the test by which the output water from a water purifying apparatus is sampled int
39、o a Sam- ple container. Carry out the test as swiftly as possible after the sample was taken(6). Note (6) In case of the sample being kept in a container, put its adequate amount in a small-type Erlenmeyer flask instead of making sampling of 5 . 1 . 2 e), then test it. a) sample container from boros
40、ilicate glass, polyethylene, polypropylene, polystyrene, and so on. washing method of sample containers shall be as follows. Sample containers shall be the air-tight ones which are made b) The washing method of sample containers 1) Wash sufficiently with Al water. 2 ) . Put Al water by about quarter
41、 of whole volume of a sample container, stopper it, and shake it violently for about 30 s for washing. Repeat these procedures 5 times. 3) Fill A3 water (or the water equivalent to target water), stopper closely it, allow it to stand for at least 16 h, and discard the water. 4 ) Fill the water the s
42、ame as in 3), stopper closely it, and allow it to stand until the sample is taken. c) sampling Sampling shall be as follows.

Put the sample introducing tube into a sample container until its end reaches on the bottom of the container, let the sample overflow from the sample container by about 5 times volume of the container, draw out the
45、sample introducing tube, stopper closely it after sufficiently washing the stopper(5). Remarks : When the electric conductivity of highly purified water is measured, the procedures during sampling and measuring shall be carried out care- fully enough not to give the influence on electric conductivit
46、y. The fac- tors, by which electric conductivity may be changed, are such as, the dissolution of carbon dioxide owing to the contact with air, the direct contact of sample introducing tube with target water, dissolving impu- rities from the thermostat for temperature control and from the detec- tor.
47、 The materials for little dissolution of impurities are, stainless steel, borosilicate glass, polyethylene, polytetrafluoroethylene, and the like. Attaching or absorbing of dirties may cause the contamination owing to its dissolving out, therefore the materials of piping and detec- tor shall be repe
