鉛酸蓄電池所用蒸餾水標準

一、         物理特性（Physical specification of purified water）

1、              Measurable water conditions: The water to top up the lead acid batteries must be clear, clean color free, on sellable and free of oil particles(See DIN 38 404 part 1 and part2)

外觀：必須清澈透明，無色，無味，無油等雜質（參見DIN 38 404第1部分和第2部分）

2、              PH value: the pH value can be tested accordingly DIN 19360,the permissible value must be between pH=5 and 7；

PH值：PH值符合DIN 19260標準其允許范圍在：5~7之間；

3、              Electrical conductivity: the electrical conductivity of the water ,when it comes out of the purifying installation must be less than 10μ s/cm.The electrical conductivity of the water to be used for topping  up the lead acid batteries must be less than 30μ s/cm(See  DIN 38 404 part 8).

導電系數：蒸餾水剛制成時，導電系數應低于10μ s/cm，加到鉛酸蓄電池中時，蒸餾水的導電系數應低30μ s/cm（可參見DIN 38404標準第 8部分）

二、         化學無素含量（Chemical specification of purified water）

The maximum permissible impurities of the water to top up the lead acid batteries are given in the table

加到鉛酸蓄電池中的蒸餾水的雜質最大允許范圍請參見下表。

三、         蒸餾水的儲存（Storage of purified water）

The purified water need to be stored in the clean appropriate containers, made of glass, hard rubber, polypropylene, PVC, The tubes must be made of Polyethylene, PVC or rubber.

蒸餾水必須儲存在清潔的適當的容器內，容器的材料可以玻璃、硬橡膠、聚乙烯、聚丙烯、聚氯乙烯。管子的材料必須是聚乙烯、聚氯乙烯或硬橡膠。

Metal containers are not allowed, as there is risk to Metallic lons that may come out the material. In case glass containers are used, then there is the risk of the evolving the Sillcium acid (SiO₂) Kieselsaure out of the glass material, It is not harmful and it will reat in the residue of the water.

不允許使用金屬容器。因使用金屬容器可能會有金屬離子從材料中游離出來。如使用玻璃容器時，可能也有硅酸鹽離子從玻璃材料中游離出來，但這種離子無害且會吸附到水中的雜質上。

Water must be kept in a closed containers, as it will absorb Carbon-dioxide (CO₂)out of the air, Which increase the electrical conductivity of the water.

因為蒸餾水會吸收空氣中的二氧化碳從而使它的導電系數增加因而儲存在密閉的容器內。
