Regarding the definition of flow mixed gas corrosion test chamber
Because the technical committees are participated by all the national committees of interest, because
These formulated documents are used in recommendation and published in the form of standards, technical reports or guidelines, in which the national committees are accepted by States.
In order to promote unity, the IEC National Committee agreed to use IEC standards in its country and regional standards. Any difference between the IEC standard and the corresponding national standard or regional standard should be clearly explained in the latter.
IEC did not provide a logo program that indicated its approved, so it was not responsible for any devices claimed to comply with IEC standards.
Standard IEC 68-2-60 is developed by the IEC No. 50 Technical Committee (environmental test).
Standards for determining the indoor environment of operating or store on electronics electronics components, equipment and materials, especially contacts and connectors, can also assemble a sub-system or assembly to become a complete device. Cut the assessment.
The information given by the standards provided by the standard, which can help the material, manufacturing process, and component design on the basis of comparative corrosion resistance.
The standard specified test equipment includes a climate system, a sample chamber, a gas delivery system, and a gas concentration detecting device.
The design and structural details of the device are optional, but the conditions specified in each test method should be met in its entire working space. And
should meet the following requirements:
should be sufficiently clean, so as not to affect the test effect;
Test gas passed the sample In the room, it should ensure the consistency of the test conditions in the working space;
The definition of the working space is: corrosion weight of each point of each point in the working space ZuiThere is no more than 15% of the average corrosion weight of all copper sheet.
