Cable Corrosion Tester for IEC 60754-1 and IEC 60754-2

Cable Corrosion tester

Cable corrosion tester includes the Electric control box, Heating furnace, Electromagnetic stirrer, Conductivity meter, and PH meter. It complies the IEC 60754-1 and IEC 60754-2. It is suitable for the acidity of the gas released by the materials on the cable or optical cable components under certain conditions.


IEC60754-1/BS6425-1 Halogen Gas Content Determination:

In test 1 of Cable Corrosion tester, this test is according to the IEC 60754-1.This is the specification for the release concentration of hydrogen chloride (HCL) in the IEC and BS standards. Halogen contains fluorine (Florine), chlorine (Chlorine), bromine (Bromine), iodine (Iodine) and radioactive volatile element Astatine (Astatine), the composition is very toxic. The experiment stipulates that when the combustion furnace is preheated to 800°C, a built-in 1.0g sample is pushed into the furnace, the HCL is dissolved into the water using the air flow rate, and then the halogen acid content of the aqueous solution is measured. If the amount of halogen acid (HCL) released when the cable material is burned is less than 5mg/g, it can be called a halogen-free cable (LSOH). If the amount of halogen acid (HCL) released is greater than 5mg/g but less than 15mg/g, it can be It is called low halogen cable (LSF). It is worth noting that the IEC60754-1 method cannot be used to determine materials with an HCL content of less than 5 mg/g, that is, it cannot be determined whether it is "halogen-free". Need to determine whether it is completely halogen-free can be determined by the IEC60754-2 method.


IEC60754-2 Gas Acidity PH Test:

In test 1 of Cable Corrosion tester, this test is according to the IEC 60754-2.This is the specification for the corrosiveness of combustion gas in the IEC60754-2 standard. This test measures the acidity of the halogen acid gas produced by the material during combustion. It is determined by the pH value and conductivity of the aqueous solution. The experiment stipulates that the combustion furnace is preheated to 800°C, a quartz tube with a built-in sample is pushed into the furnace, and the time is started at the same time. In the first 5 minutes of burning the sample, the pH value and electrical conductivity are measured every 1 minute, and every 5 minutes for the next 25 minutes. Generally, the PH value of halogen-free cable materials is greater than 4.3, and the conductivity is less than 10μs. The lower the PH value, the higher the acidity of the halogen acid gas of the material. It is worth noting that when the HCI content is greater than 2mg/g and less than 5mg/g (that is, when it meets the requirements of IEC60754-1), the pH value of its aqueous solution is also less than 4.3, that is, it does not meet the requirements of IEC60754-2.
