The Taber Scratch Tester

 Scratch Resistant tester is a motorised scratch tester used to test the resistance of many materials to scratching, shearing, gouging, marring, scraping and engraving.The height of the scale beam is adjusted by the user to match the thickness of the sample. The tool, a conical diamond tip, is then placed on the sample and the instrument is activated by the user with the On/Off switch.



The tip leaves a trace mark and the extent of this, in relation to the load used, indicates the degree of coating or material hardness. The turntable rotates at a constant 5rpm to ensure repeatability and reproducibility of tests. By changing the load on the tool, from 0 - 1000g (0 - 2.2lb), the sample’s scratch resistance can be  evaluated.

Scratch tester is applicable to all types of wiping performance test of automotive interior materials; test equipment integrated three domestic standards (fingers scraping method, a hundred grid method, and plastic scraping finger scraping method).

This adjustment allows the scale beam to be maintained in a level position in respect to the specimen and turntable.  Designed with an integrated bearing, the scale beam can be tilted in a rest position enabling the operator to mount or remove specimens.

Determination of air permeability of a fabric-air permeability tester

Fabric air permeability is a measure to what extent it gives air passing through the fabric. Air permeability, a given area in the vertical direction of the air flow rate, a given time period, is measured by the fabric test area inside the pressure difference of the fabric. Basically, it depends on weight, thickness and porosity of fabric. The porosity of fabric is the demonstration of the air gap as a percentage within fabric. It has been important for especially the tent fabric, parachute fabric, raincoat fabric and garment, the fabric used in air bags, industrial filters and sail cloth. Moreover, when thermal properties of clothing and body interaction are taken into consideration, there has been the effect of air permeability. there is an instrument which is designed to test the air permeability of fabric on the market .it is air permeability tester . Air permeability is an important feature of fabrics (Sundaramoorthy et al., 2011) and is one of the main factors affecting the t...

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 ...

3 main functional values of the Burning Manikin System

3 main functional values of the Burning Manikin System 1) Research on the heat transfer mechanism of individual soldier's flame retardant equipment By simulating the battlefield fire conditions of different intensities, the changes of human skin surface heat flow and skin temperature by burning dummies, a good human body-clothing-fire environment conditions are created, and the individual soldiers are flame retardant The study of equipment heat transfer mechanism provides an important research method. 2) Research and screening of flame retardant fabrics for individual soldier equipment Quantitatively test the flame retardant properties of different individual soldier equipment fabrics through the burning dummy system, guide the research on flame retardant fabrics, and screen out flame retardant fabrics with excellent performance. 3) Structure and style design of individual soldier's flame retardant protective equipment The structure and style of individual soldier's flame r...
