Operating Procedures of Glow Wire Testing

Glow wire tester will specify the material and shape of the electric wire with a large current heated to the test temperature, the specified pressure (1.0N) vertical hot test sample 30s, depending on the test and bedding is ignited or burning time to determine Electrical and electronic equipment, the risk of fire products; Determination of solid insulation materials and other solid combustible materials, ignition, ignition temperature, flammability and flammability index.

Glow Wire testing Apparatus Operating procedures1, glow-wire test machine before the preparation of the operation2, be sure to read the use of instructions, and follow the instructions step, followed by operation;3, do not use non-original accessories, so as to avoid danger;4, glow wire test machine on the room to the oil ventilation equipment (or with a special ventilation hood in a small laboratory), in order to test the exhaust after the discharge.5, the two matching weights with copper wire (connected to the sample rack) by the left side of the two pulleys (through the corresponding hole) hanging under the bracket plate.6, according to the standard requirements of interest and clamping samples.7, close to the adjustment of the switchA. The nut that is fixed to the switch is loosened and moved left and right;B. Press the "left button" car automatically forward, when the sample contact with the hot wire, the hand close the switch, so that the car stopped before the fixed and close the switch.C. Press the "Heating" button to adjust the current adjustment knob. According to the requirements of the sample, adjust the appropriate current value, while the temperature is required to meet the test requirements of the required temperature.


When the test piece touches the glowing wire head, the limit electromagnet is released and the 1N weight can only be moved forward by 7mm.When the experiment is finished, eject the heating button and then turn the current adjustment knob to the minimum.

  2. The glow wire test for plastics is to determine the resistance to fire insulating parts. And the glow wire test simulates the situation of what the plastics material will happen when contact with an over-heated part.

The Leather Friction Color Fastness Tester

Leather friction color fastness tester applied to test leather property in shoes, clothing, luggage handbag industry, research laboratories; commodity inspection, arbitration and technical supervision departments.Leather friction color fastness tester test the degree of decolorization of dyeing leather after friction. It can used to test the leather color resistance to dry, wet and friction. This instrument is suitable for leather, textile, belt, trademarks, cardboard and other friction materials by foreign object damage and decoloring. The machine is designed to carry out a rub fastness test on the surface of leather or coated fabrics to determine the marring of the surface finish and to assess the amount of color transfer from the sample to the rubbing pad. This machine is designed to determining the colorfastness of leather, plastics and textile materials. The colorfastness is assessed by checking change in color of the specimen and stain of the felt after rubbing the ...

How Sublimation Fastness Tester Works?

Sublimation Fastness Tester is a suitable instrument for dyestuff manufacturers as well as textile processors for checking effects of dry heat on dyestuff. Qinsun-lab offers Sublimation Fastness Tester of the best quality and at the best price which gives accurate results.    Features of Sublimation Fastness Tester : Testing the effect of direct heat on the dyestuff; up to 250°C temperature range; Independent digital timers with the minimum display of 1℃(one with each of top and bottom plates, respectively); Can test entire range of temperature in a single test.                           Working Principle: A dyed cloth piece is sandwiched between two undyed pieces and placed to cover the heat pads and the test goes on for a preset time period. The fabric pieces should be picked up immediately. The undyed fabric pieces will be stained by the dyes. This gives the sublimation fastness ...

what is the Working Principle of fogging tester?

Fogging Test Chamber   is the best tool to determine the fogging characteristics of automotive or other vehicle interior materials. The fogging tester is applicable for gravimetric method, photometric method and haze measurement method. Working Principle: The main frame of the Fogging tester includes a water sink fully filled with specified ethylene glycol, which can reach a high temperature. At the time of testing, leather specimens are put in the six standard glass containers filled with  high temperature liquid, and the stainless steel containers are placed above each glass. Relying on the constant water flow distribution, the temperature can maintain at 20℃ constantly, and it can be adjusted through the regulation device connected to the main frame. This controlled environment condition will generate a layer of “fog” on the surface of specimens. The operator can determine the fogging characteristics of materials based on gravimetric analysis method or refraction...
