He/she can set the Martindale HPAT400 Pass/Fail PAT Tester to perform automatic, full test sequences for Class I or Class II appliances or power leads. This instrument also includes an IT-safe 200mA earth bond test. A safe isolation set including a Martindale VI13800 Voltage Indicator, PD440S Proving Unit, and TC71 Combination Carry Case Thankfully, there are ways to know how resistant a fabric is to abrasion. Two testing methods exist: the Martindale and the Wyzenbeek. Both of these tests, popular in different parts of the world, provide consumers with a reliable indication of a fabric’s durability as well as its suitability for use in high-traffic public settings. When you choose fabrics that are resistant to abrasion, you can be sure that the items will be able to withstand heavy use, frequent cleaning and other types of mechanical stress. Not only that, but they’ll also maintain their appearance and functionality for much longer. What is the Martindale test?change from time to time, are paid. Licensee and/or ASTM have the right to terminate this Agreement

The standard rubbing cloth cannot be used repeatedly, and another standard rubbing cloth needs to be replaced to complete a test. Textiles / Determination of abrasion resistance of fabrics by Martindale method, par 4: Assessment of the appearance change Test piece of fabric is placed in the specimen clamp, and it will be rubbed against with abradant in a Lissajous figure. According to the requirement, once the test piece is broken, test piece should be taken down to calculate its abrasion resistance index, or evaluate its ratingof pilling through the visual description of abrasion. ENISO12947.2-1998 The abrasion and pilling resistance testing of fabrics by the Martindale method-part 2: measurement of specimen breakage;

Martindale VIPD138-S Voltage Indicator & Proving Unit Kit Key Features

This method is applicable to all textile fabrics, but not to fabrics with a low abrasion wear life. The Martindale VIPD138-S Voltage Indicator & Proving Unit Kit is a reliable, practical, and durable safe isolation set. Martindale VIPD138-S Voltage Indicator & Proving Unit Kit Key Features Applicable to all textile fabrics, but not to fabrics with a low abrasion wear life. The requirements for the selection of abrasives, the sampling method, the specimen fixture liner, the total effective mass of the friction load and the abrasive replacement interval are the same as those used for the determination of specimen breakdown. These are not repeated here. Selection of abrasives. Different standard abrasives are selected according to the characteristics of the specimen.

Because different countries and different regions have different standards, we can divide them into international standards, American standards, European standards, Chinese standards, and so on. The details are as follows: Martindale abrasion machine is suitable for testing the abrasion resistance and pilling degree of knitted fabrics, woolen fabrics, artificial leather, synthetic leather, etc. under pressure, which is used in many industries such as textile, footwear, and garment. Textiles / Determination of abrasion resistance of fabrics by Martindale method, part 2: Determination of sample breakdown ASTM D4966: Standard Test Method for Abrasion Resistance of Textile Fabrics (Martindale Abrasion Tester Method)There are various factors that affecting abrasion resistance measurement. Thus, you may need a pilling machine to test the wool abrasion resistance and abrasion resistance of test fabric. Let us introduce the Martindale rub test guide and help you to get Martindale abrasion test results. Under a certain load, the specimen in the fixture is rubbed against the abrasive in a Lissajous curved plane, when the specimen has been rubbed a specific number of times, the abrasion resistance is determined by the mass difference before and after rubbing. The Martindale method is applied to the abrasion resistance of knitted fabrics, woolen fabrics, artificial leather, synthetic leather, etc. under a certain pressure. It is applied in the form of flat abrasion and is generally analysed and evaluated in three aspects: determination of the specimen breakdown, determination of the loss of mass and assessment of the appearance change. If the end point of the abrasion test is the rub count specified in the agreement, the post-test specimen is compared with the pre-test specimen and the degree of discoloring, fuzzing, and pilling is rated as a change in appearance quality. The principle of the Martindale test is to place a textile or other material of a certain size on a rotating wheel, and then let the wheel rub repeatedly under a certain load. In this process, the wheels will drive the textile or material to move under certain speed and pressure, which will cause wear and tear. The test results are usually expressed by the wear amount or wear rate of the yarn or fabric. The smaller the wear amount, the better the wear resistance of the material.

If the fabric gives 25,000 to 30,000 rubs, then it can be used for heavy-duty (on the main furniture in the house which will be used daily and continually). According to standard, we settle the number of times on the tester and turn on it. Won’t be stop itself until it achieves enough times in the measurement. First of all, with the continuous development of artificial intelligence and machine learning technology, Martindale testers may gradually realize automation and intelligence, and improve the accuracy and efficiency of testing by analyzing large amounts of data. Secondly, the Martindale tester may use more advanced materials and manufacturing processes, such as nanomaterials, superconducting materials, etc., thereby improving the sensitivity and accuracy of the test. During friction the fibres constantly collide with each other and fibre fragments break due to fatigue damage, resulting in the breakage of the yarn.A:Two circular samples of same material rub mutually in a certain pressure along Lissajous curves. Then after reaching stated circles, pilling of test sample should be measured. Martindale test uses figure 2 among four types of Lissajous-Figure. Adopt servo motor control to improve the stability of machine operation and reduce machine noise. Choosing Martindale Abrasion Tester TF210 means choosing reliable rub testing results. Set a certain number of rubs as an inspection interval to observe the wear state of the specimen surface. The test ends when the sample is broken or when the specified number of rubs is reached.
