3 Definition
This Standard applies the following definition.
3.1 bottled purified water for drinking
6.3.1 Type inspection shall be carried out once a quarter or a production cycle. The type inspection shall be carried out in in any of the following cases. a) change of main raw materials or key process;
b) resumption of production after long-term discontinued production;
c) requirements for type inspection proposed by state quality supervision organization.
6.3.2 Sampling method and quantity
From any batch of product, 18 bottles (cans) shall be randomly extracted. 9 bottles (cans) are used for the inspection of sensory requirements, net content, physical and chemical indicators [3 bottles (cans) for net content inspection]; 3 bottles (cans) are for the inspection of microorganisms; another 6 bottles (cans) are for standby.
From any batch of product, 18 bottles (cans) (6 bottles for over 2L) shall be randomly extracted. 9 bottles (cans) (2 bottles for over 2L) are used for the inspection of sensory requirements, net content, physical and chemical
indicators [3 bottles (cans) (2 bottles for over 2L) for net content inspection]; 3 bottles (cans) (2 bottles for over 2L) are for the inspection of microorganisms; another 6 bottles (cans) (2 bottles for over 2L) are for standby. [See Amendment No.1]
6.3.3 Type inspection items
It shall include all items required by technical requirements of this Standard. 6.4 Determination rules
6.4.1 In exit-factory inspection results, if sensory requirements, net content, pH value, conductivity fail to comply with this Standard, it shall conduct re- inspection by double-sampling from this batch of products for unqualified products. If there is still one item fail to comply with this Standard in re- inspection, this batch of products shall be determined as unqualified. Should total number of colonies and coliform fail to meet this Standard, this batch of products shall be determined as unqualified.
6.4.2 In type inspection results, except net content, if one item fails to comply with this Standard, this batch of products shall be determined as unqualified. In net content, when negative deviation of one bottle (can) exceeds the allowable negative deviation OR the average net content is less than the indicated net content, it shall allow to conduct double-sampling for the re-inspection of unqualified items. If one of the abovementioned cases still exist, this batch of products shall be determined as unqualified.
7 Marks, packaging, transport, storage
7.1 Marks
7.1.1 On the product label, it shall mark in accordance with relevant provisions of GB 7718. product name, net content, name and address of manufacturer (or distributor), date of production, shelf life and product standard number. The product name and net content must be ranked in the same field of vision. 7.1.2 The product processed by distillation method can use the name of
?€?distilled water?€?. The product processed by other methods must not use the name of ?€?distilled water?€?. When using ?€?new created name?€?, ?€?peculiar name?€?, ?€?designation name?€? or ?€?brand name?€?, ?€?purified water for drinking?€? must be indicated in eye-catching words after its product name.
7.1.3 On the packaging box, in addition to product name, name and address of manufacturer (or distributor), it must also indicate the net content and total number of single package.
7.1.4 Marks for storage and transportation icons shall comply with relevant provisions of GB 191.

(Standard annex)
Determination of conductivity
A.1 Method summary
Conductivity refers to the reciprocal of resistance measured between two electrodes from 1 cm and cross-sectional area of 1 cm2, of which the reading can be directly read by conductivity meter.
A.2 Instruments and reagents
A.2.1 Instruments
A.2.1.1 Conductivity meter (with matching conductivity electrode).
A.2.1.2 Water bath thermostat.
A.2.1.3 100 mL or 250 mL beaker.
A.2.2 Reagents
0.0100 mol/L potassium chloride standard solution. TAKE a small amount of potassium chloride (guaranteed reagent), DRY in 110??C dryer for 2h, accurately WEIGH 0.7456 g after cooling, DISSOLVE in heavy distilled water which is new boiled and cooled (conductivity is less than 1 ??S/cm), TRANSFER to 1000 mL volumetric flask and DILUTE to scale. The conductivity of this solution at 25??C is 1411.83 ??S/cm. The solution shall be stored in hard glass bottle with glass plug.
A.3 Analysis steps
According to instructions on use of conductivity meter, select the electrode and measurement conditions. Adjust the conductivity meter. Use the solution to be tested to wash the electrode for 3 times. Insert it into the beaker (A.2.1.2) [Translator note. it should be A.2.1.3] full with the solution to be tested. Select the appropriate range. Read the reading on the meter then the conductivity value of the solution to be tested shall be calculated.
NOTE
1 The electrode lead must not be affected with damp or it shall affect the measurement accuracy.
