CRA IEC 60754 Part 1, 2 Electric Cables Corrosion Test Apparatus
Product Description
CRA IEC 60754 Part 1, 2 Electric Cables Corrosion Test Apparatus measures gas volume of Halogen Acid (IEC 60754-1), pH concentration(PH Meter, Hydrogen ions, IEC 60754-2), Conductivity(IEC 60754-2) and etc from a wire (cable) by radiant heat in the Tube Furnace (IEC 60754-1: 800°c, IEC 60754-2: 950°c);
Especially, it can test both IEC 60754-1 and IEC 60754-2 standards by one equipment and mode select function;
IEC 60754-1 is halogen-free cable came from and including the polymer to halogenated compounds on the basis of the additive compounds emitted during combustion, except the fluoridation hydracids, it is measure for gas of halogen volume.
IEC 60754-2 is for electrical or optical cable from compounds emitted during the combustion of measure the gas of oxidation limit.
About reproducibility of the test, reliability and convenience of the user to insert the automatic feed devices for combustion boat, turning-rail for easy to put the specimen, the setting of automatic timer, air-filtering and etc.
Product Parameters
- Tube Furnace: For heating section of furnace, its length is 500mm and inner diameter is 40mm. It also contains electrically controllable heating system(Temperature Controller).
- Tube (Pyrex): Fire resistant tube is used in the furnace to protect tube against corrosive gases. The tube is made in silicon dioxide fire-proofing agent. Inner diameter of silica tube is 38mm and the length of tube is 150mm from the entrance of furnace and tube is protruded in a distance of 100mm from the exit.
- Combustion Boat: 98mm(Length)*15mm(Width)*12mm(Depth); Each boat is used only three times before combustion or recycling. (It shall be cleaned after it is used three times.)
- Gas Washing Bottle: Height of liquid in the end of tube shall be 100 ~ 120mm in each bottle.
- Air Supply System: Gas used for combustion shall be air and flow rate of air injected into the tube shall be adjusted according to the actual inner cross section of tube. The speed of air flowing across the sample shall be 378ml/min ±10%.
