Horizontal and vertical burning tester

 


UL94 horizontal and vertical combustion tester is designed to simulate the early firing situation of electronic and electrical products in order to evaluate the firing hazard through this simulation technology,. when the products are on fire the tester needs to ensure that the flame around the products shall not spread around. The tester is used to conduct flammability experiments for materials of equipment and  components, and measure the test indices, such as flammability property, burning rate, flame spread, combustion intensity and  the flame retardant property of products. It is a latest listed tester extremely recommended to clients with high requirements in terms of its high automation and accurate test data.

How To Process The Elmendorf Tear Strength Test

The Elmendorf tear tester has been developed specially for the paper industry and is outstanding for simplicity of operation and high measurement accuracy. The exchangeable pendulum is equipped with a pneumatic sample clamp. The initiation and return of the pendulum, as well as sample cutting is completely automatic. The device is operated via an integrated touch screen, where the test method can be selected, specific settings can be adjusted, and, after the measurement, results and statistics can be  displayed.Each pendulum is supplied with the appropriate control weight so that, with the help of the service program, it can easily be checked for functionality and balance. The Elmendorf tear test Procedure:     Cotton fabric was taken.     Warp and weft direction of the fabric was identified.     Two strips were cut from the fabric in both directions having dimensions of 100 x 63.5 mm.     The sample was then fixed in the jaws of the ...

Correct Use Of Color Assessment Cabinet

Observation Angle: The following points are all the facilities required for the Color Assessment Cabinet , and the viewing Angle will directly affect the evaluation results. According to international standards, there are only two observable angles that can be used. They are: A, zero light source and 45 degrees observation (0 °, 45 °), the light from zero (vertical) incident Angle on the sample, sample watchers from 45 degrees. B, light source and 45 ° inclined channel 45 degrees of light source, zero observation (0 °, 45 °), the layout must use specific 45 degrees of inclined (45 ° Fixed Angle table) making from 45 degrees of light source on the samples, sample watchers from zero (vertical). The location of the 45 ° light samples: Regardless of any of the above observation methods, it is important to note that the test sample is placed in the middle of the light box as far as possible to reduce the influence of the external light source. In addition, the most important thing...

The Scratch Tester Working Principle From Qinsun LAB

The scratch test machine is used to evaluate the shear, scratch, planing, scraping and engraving performance of the material. Its applications include rigid organic materials, plastics and glass, and so on. The test parameters, such as the speed of scratches, the length of scratches, the distance between scratches and the number of lines, are the test equipment with strong applicability and convenience. scratch tester Working principle: Coating has three aspects: the action of protection, decoration, and hide the defects of products, and the three main hardness has a lot to do with paint, paint film hardness is said film one of the important properties of mechanical strength, is an important indicator of measuring coating product quality, and measure the coating hardness is an important index of the scratch resistance of determination; Coating good product in the process of packaging, transport and use will draw by hard brush, not row brush the paint film is often leave scratc...
