Other irregular samples are recommended to remain tilted. The V-groove has a single weighing capacity of 3KG, and the O- bar has a single bearing capacity of 5KG. It is strictly forbidden to place samples under heavy weight. How do you do a salt spray test? 1. First power on the salt spray test chamber (plug in) 2. Press the red power switch panel from left to right, respectively: the low water level A light is on, the low salt water B light is on, and the low water level C light is on. 3. Pour distilled water directly into the test chamber, wait until the water level A indicator light off, and stop adding water. […more…] How Long does a Salt Spray Test Take? The Salt Spray Test Chamber is an environmental test equipment that evaluates the corrosion resistance of products or metal materials by artificially simulating salt spray environmental conditions. The chloride concentration in the salt spray environment can be several or tens of times the salt spray content of the general natural environment, which greatly increases the corrosion rate. The salt spray testing of the product can greatly shorten the time to obtain the result. For example, if a product is tested in a natural exposure environment, it may take 1 year for its corrosion, while a test in salt spray test chamber may take as long as 24 hours to obtain similar results. How to use a salt spray test chamber to determine the corrosion resistance of LED lamps? Salt spray test is a kind of environmental reliability test, mainly used to test the corrosion resistance of metal materials of lamps. In order to verify whether the metal parts on the product will corrode when exposed to the atmosphere or other environments, the product can be placed in the use environment for a long enough time, such as a product life cycle. This is time- consuming and labor-intensive. In practice, it is rarely used, so a convenient method is needed to evaluate the corrosion resistance of the product.

These kinds of format files can be transferred by other illumination and luminaire design software such as DiaLux. What are the types of goniophotometer? The types of Goniophotometers can be basically divided into Type A, Type B and Type C. For a detailed description, please refer to the 1987 edition of CIE 70. The difference between them lies in the way the lighting equipment rotates during the measurement and the photometric data obtained during this measurement. How does goniophotometer measures? Goniophotometer is a device used to measure the light distribution performance of lamps. Goniophotometer measures the spatial light intensity distribution of lamps or light sources, total luminous flux and lamp efficiency and other parameters. Goniophotometer need to work in larger darkroom. Use low-reflectivity materials in the room to avoid reflected light from entering the probe. Depending on the arrangement of the measuring light path, two measurement schemes can be used to measure the luminous flux: the illuminance integral method and the luminous intensity integral method.
