科迪仪器生产的盐水浸泡试验机完全满足欧盟标准EN ISO 8442-2:1998,每分钟升降3次可设定!

EN ISO 8442-2:1998标准中关于盐水浸泡测试的内容如下:

C.4.2 Fill the container with the sodium chloridesolution (see C.2) using at least 1 litre of solution for every square decimetre of area of the stainless steel parts of the samples. Bring the container and contents to 60 °C ± 2 °C. Maintain at this temperature. Do not allow the temperature of the solution to exceed 62 °C at any time, even before the start of the test. Use a fresh sodium chloride solution for each test.
NOTE The temperature of the sodium chloride solution may be conveniently maintained at 60 °C ± 2 °C by positioning the apparatus in a thermostatically controlled water bath, the level of which is maintained at approximately the same level as that of the sodium chloride solution.
C.4.3 Place the test specimen in the rack and, in the case of knives with stainless steel handles, support the handles in such a way that they do not come into contact with the rack. Replace the cover.
C.4.4 Completely immerse and completely withdraw the test specimens from the solution at the rate of from two to three times per minute for 6 h.
C.4.5 At the conclusion of the test period, thoroughly wash and rinse the test specimens and examine for corrosion.
NOTE Products of corrosion that impede visual examination of corrosion pits should be removed by hand rubbing the surface of the cutlery with a stainless steel polishing paste applied with asoft cloth.
C.5 Expression of results Assess the size and number of pits per test specimen and the length of longitudinal cracks visually with the aid of a calibrated microscope or lens of at least four times magnification. Where two pits have obviously merged together they shall be assessed as
two separate pits.
NOTE The use of wires of diameter 0,4 mm and 0,75 mm respectively, placed in contact with the sample surface, provides a convenient method of assessing the size of pits with a hand lens.
针对上述ISO 8442-2:1998测试标准要求,科迪仪器专业生产封闭式盐水浸泡试验箱开放式盐水浸泡试验箱,保证测试产品浸入在盐水中和停留在空气中每分钟2到3次,连续进行6个小时的测试。

盐水浸泡试验机的技术特点:

1、盐水温度:RT+5到60度范围内可设定;

2、根据特定产品可制作不同的夹具;

3、升降装置做到每分钟升降2到4次可调;

4、加热器不以金属材质接触盐水。
