Flammability Tester Standards and application

    Combustion tester for a variety of wire and cable insulation coating materials, printed circuit board materials, IC insulators and other organic materials, resistance to burning test. Test, the test piece as the top of the flame, burning 15 seconds, off for 15 seconds, repeat 5 times after the test specimen was burned, can set the burning, extinguishing time and the number of repetitions, and automatic operation.        Flammability tester   Standards compliant: 1, Horizontal Combustion Test: UL94HB (ASTM D 635, IEC 60695-11-10, IEC 60707, ISO 1210) 2, vertical burning test: UL 94 V-0, V-1, or V-2 (ASTM D 3801, IEC 60695-11-10, IEC 60707, ISO 1210) 3,500w (125mm) Vertical Combustion Test: 5VA or 5VB (ASTM D 5048, IEC 60695-11-20, IEC 60707, ISO 9772) 500 W (125mm) 4, thin material vertical burning test: VTM-0, VTM-1, or VTM-2 (ASTM D 4804, ISO 9773) 5, the level of foam material combustion test: HF-1, HF-2 or HBF (ASTM D 4986, ISO...

What Is Hydrostatic Head Tester?

      Hydrostatic Head Tester is designed to determine the waterproof property of outdoor wears, umbrella, and waterproof fabric. It is also used to test the resistance of permeability of synthetic blood for materials used in protective clothing. Dynamic, static, custom mode for different test requirements. One side of the specimen is subjected to a hydrostatic pressure that increasing at a constant rate, then will be ended until three points of leakage appear on its other side. The instrument contains a high precision pressure control system, which could produce the test pressure in an internal water tank. Real-time pressure curve displays on the screen. Easy to use of build-in test mode for different standards. Hydrostatic Head Tester Test Procedure Cut  the test fabric  into 100mm × 100mm size of the sample, and then put the sample into the fixture, tighten the fixture fixed.  Press the up button, the metal container containing 700ml of water ...

Understanding A Fogging Test Chamber

        Fogging Test Chamber   ,To determine the fogging characteristics of automotive interior trim of textiles, plastic or leather. Fogging is the residue deposited on interior glass of chemicals released from materials under specific temperature conditions.       The sample is heated in the  fogging tester   fog cup and begins to evaporate, and the volatilized gas is condensed on a glass or aluminum foil that has been cooled by the cooling chamber.     After the completion of the condensation process, the glass plate or aluminum foil was removed. Atomization and volatilization characteristics of the sample were obtained by measuring the atomization value or weight of the condensing component of the glass plate or aluminum foil and compared with the data before being condensed.      Gloss method: The sample is condensed in the fog cup by the vaporized gas condensed on the low temperature glas...

How To Do Abrasion Testing With Taber Abrasion Resistance Tester

    What is abrasion tester ?Fabric Abrasion Tester  is Suitable for woven, knitted, woven, decorative materials, coated fabrics and other apparent abrasion resistance testing and pilling performance test. Fabric Abrasion Tester   Operation  Method  1、Sample preparation: In the standard environment, tiled, without stretched state, place it for a period of time according to different standards. As24 h(G B /T 4 80 2 .2 一 19 97),16h(EN ISO 12947-4:1998) 2、samples Selection: Cut a sample from different parts of the entire width of fabric and, the sample to be representative. If it is fancy fabric sample, which should include all the different organizations and cloth made from color rendering. 3、Remove the load and the upload the shaft from the Abrasion test machine : 4、Remove the top plate and the test fixture: 5、Sample Device:      Loosen the retaining ring on the test fixture, scored tablet sample...

What Is Fabric UV Resistance Tester For ?

    Fabric UV resistance tester also known as SPF & UPF Tester, anti-UV performance tester , anti-UV transmittance tester. Reflective, transmission of these two modes is the basic means of spectral measurement. To achieve these two modes of spectral measurements, usually require spectrometers, light sources, optical fibers, measurement scaffolds, standard reference samples, and measurement software. For the different types of samples, in order to obtain the best spectral data, reflection, transmission of these two basic models will evolve into more forms.     Ultraviolet transmittance tester  uses CCD detector, do not scan, save time, especially when the sample is more obvious at the same time because there is no scan, there is no raster calibration, spectral distortion  caused by the results of instability is not accurate The At the same time the use of LED light source, good stability, the intensity is adjustable, resulting in a small heat, s...

Introduction of Multi Finger Scratch Tester

   Scratch resistance is not uniquely defined, and is difficult to measure. Different terminologies are used, ranging from marring for optical defects towards friction, wear, erosion, abrasion and cracking for mechanical defects.1,2 The scratch resistance can be evaluated in terms of gloss reduction, haze, magnitude of deformation, resistance towards deformation, weight loss or color change of the substrate.       Multi Finger Scratch/Mar Tester uses tungsten carbide as a scratch to accurately detect surface damage caused by unconventional physical forms (such as scraping, grasping, planning etc). It can be used to detect the wear resistance of plastic parts in automobile interior and exterior trim, and can also be used for the testing of hard material wear, paint, ink, soft metal, oil carpet and other materials.         The test sample is fixed on a compressed air driven test platform of five finger tester . Five independent shaft...
