EN/IEC61000-4-2,ISO10605 EMC ESD Simulator

The Method of ESD tester mainly produces EMC disturb problems

The ESD tester is actually an electrostatic discharge generator. Static electricity is caused by the friction of two different substances, and a high voltage is formed by the accumulation of positive and negative charges on the two objects that are rubbing against each other. Man-made fibers and plastics are common triboelectric materials. When friction generates voltage, ESD problems will occur. For electronic components, electrostatic energy cannot be ignored. It can break down semiconductor components and destroy electronic circuits.   Generally, ESD [...]

Fabric Bursting Strength Tester

The Difference Between The Testing Methods Of Steel Ball Bursting Testing And Hydraulic Bursting Strength Testing for Fabric Testing

 In the process of taking, the fabric is constantly exposed to the top and pressure of the concentrated load and expands until it is damaged, especially the elbows, knees and other parts of the clothing. This damage is called bursting or bursting.          Because the fabric is subjected to the pressure and pressure during the wearing process, the fabric stretches longitudinally and shrinks transversely. If only the tensile breaking strength of the fabric is tested, it must be tested in the [...]

AATCC22: Water repellency test-spray method

AATCC22: Water repellency test-spray method

AATCC 22 Water repellency test: spray method  Purpose and scope       The standard applies to any textile fabric, regardless of whether it has been treated for water repellency. This standard can determine the water-wetting resistance of fabrics, and is not suitable for textiles treated with water-repellent properties, especially plain woven fabrics. Because the instrument is simple and portable, and the test procedure is relatively concise, this standard is particularly suitable for factory product control. Since this standard cannot measure the penetration of [...]

TENSILE TESTING MACHINE PRECISION GRADES CLASSIFICATION

In the technical parameters of testing machine precision grades classification, we often see the accuracy of 0.5 or 1 and other parameters. What do these levels represent? Tensile testing machine 0.5 or 1 is to classify the accuracy level of the instrument. In ISO7500-1 Static Uniaxial Testing Machine Inspection Part 1_ Tensile and (or) Compression Testing Machines, the tensile testing machine is divided into 0.5 Grade 1, Grade 1, Grade 2 and Grade 3, among which grade 0.5 represents the [...]

Material Tensile Testing Machine’s Deformation And Displacement Is Same?

Deformation and displacement of material tensile testing machine are two concepts we often encounter in use. Deformation refers to the force generated by the sample under force during the test process, and its shape and size also change The phenomenon is called deformation, that is, the deformation of the test piece; and the more popular displacement is the distance that the beam moves in the testing machine from the beginning of the force (refers to the distance that the [...]
