However, in the case where the substance to be removed is such clogging substance that causes turbidity which decreases the filtered water volume, the filteri

32、he test shall be car- ried out at the ordinary temperature (20 * 15) OC and ordinary humidity (65 ifr 20) % specified in JIS 2 8703. In the measurement of pressure, the Bourdon tube pressure gauge of grade 1.6 specified in JIS B 7505 or that at least equivalent thereto in precision shall be used. Un
33、less otherwise specified, the test shall be carried out adjusting the sample water temperature to (20 i 3) OC. The concentration of the sample water shall be checked by sampling at immedi- ately upper stream of the water purifier or the position considered to be equivalent thereto. 6 Testing method

39、 needs to be fed water every time it is used such as the pot type water purifier, pass water initially through the purifier loaded with an unused filter medium in accordance with its using method. Pour water into the supply tank sufficiently fast but not so much as to make it spill out. Measure the
40、time from pouring to the point when the filtered water is fully stored in the storage tank. Calculate the filtration flow rate by the following formula from the capacity of the stor- age tank measured beforehand with the filter cartridge attached. In the case of circular type water purifier, this ti
41、me shall include the time required for the circulation of water. Prior to this operation, immerse a filter cartridge in the purified water for at least 5 min if necessary to adjust the filter with water sufficiently. The above description “the point when filtered water is fully stored in the storage
42、 tank” is defined as follows: after pouring water as fast as pos- sible, the point when the dropping interval increases to one second or longer in the case of the purifier of which filter cartridge point is not immersed in the water, or when the increase of stored filtered water is significantly re-
43、 duced or the amount of the filtered water reaches to the capacity of the storage tank in the case of the water purifier of which filter cartridge point is immersed in the water.

Rejection shall be rounded to one decimal place in accordance with the provision of JIS Z 8401. However, if the test is conducted setting up a given standard value, the results may be expressed as over or under the standard value. The rejection is expressed by the following formula. The same unit of concentra- tion shall be used for denominator and numerator in the formula, according to the substance to be
