About this deal

ENISO12947.2-1998 The abrasion and pilling resistance testing of fabrics by the Martindale method-part 2: measurement of specimen breakage; The abrasion resistance test achieves the agreed surface changes and the rub count is used as a measure of abrasion resistance. Design appropriate inspection intervals to observe changes in the appearance of the specimen, including discoloring, fuzzing, and pilling. The test protocol should specify the level of discoloring, fuzzing, and pilling on the surface of the specimen, and the test result is expressed in terms of the number of times the specimen rubs when it reaches a certain level of discoloring, fuzzing, and pilling.

Suitable for both domestic and industrial use, the Martindale VT12 Two-Pole Voltage & Continuity Tester is constructed in accordance with the latest safety standards and features GS38-compliant probe caps. It automatically detects and indicates AC/DC voltage between 12V and 690V. The voltage range is displayed on the LED scale. The Martindale VT12 Two-Pole Voltage & Continuity Tester also offers continuity testing with optical and acoustic indication up to 200kΩ. Press the corresponding button to begin automatic, complete test sequences for Class I and Class II appliances and power leads Estimate the number of times the specimen is rubbed when it reaches breakdown, on this basis, set a certain number of rubs as an inspection interval to observe the wear state of the specimen surface. Standard Wool Abrasive Fabric SM25. 1.6M wide x 5M length – For abrasion test and pilling test (when automatic) Sampling method. At least 3 pieces, the woven fabric should contain different warp and weft yarns. For jacquard or fancy tissues, each characteristic part of a complete tissue should be included, and when a complete tissue or pattern is large, each part may be sampled separately.The standard rubbing cloth cannot be used repeatedly, and another standard rubbing cloth needs to be replaced to complete a test. ASTM D4966 consists of two parts: the test method for abrasion resistance and the Martindale abrasion tester and auxiliary materials, in which the test methods are basically identical to ISO 12947.2, ISO 12947.3 and ISO 12947.4. The determination of mass loss and the assessment of appearance change differ slightly from ISO 12947.3 and ISO 12947.4 and there are simplified in terms of the end-point conditions of the test and the presentation of the test results. ★ The test procedure for textile abrasion resistance: Martindale method Determination of specimen breakdown In the future, Martindale testers may develop toward a more intelligent, automated, and high-precision direction.

The standards given above are highly influential at international level. Of these, the EU standard, the DN standard and the BS standard are all equivalent to the ISO standard. The Chinese standard is basically the same as the ISO standard, except that the application scope of the standard has been increased by the addition of coated fabrics and for the testing of coated fabrics, corresponding provisions for the breakdown of coated fabrics, friction load parameters, standard abrasives and replace requirements of standard abrasives have been added.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. Some people believe the Martindale test to be more realistic because it simulates a wider range of rubbing motions and different abrasive materials are used. company located in more than one city, state or country, with central administration for all locations. 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. Simple and easy to use – no training is needed to use one and results are displayed in a clear and easy to understand way

Both the Martindale and the Wyzenbeek tests have their advantages and disadvantages. In the UK, it is more common for manufacturers to use the Martindale test. This test is recognised as a standard method for measuring abrasion resistance in upholstery fabrics both in the UK and in Europe. That said, both types of tests are widely recognised and used. Some manufacturers and suppliers will use both tests to provide a more complete picture of a fabric’s abrasion resistance. The sampleshall be cut from different parts of the whole fabric with representative. If it is a fancy fabric , the sampleshall include all the different tissues and colors presented by the cloth. After the test is completed, if the surface of the sample has abnormal phenomena such as wear, yarn breakage, fluffing, severe pilling, and severe wear, it will be judged as unqualified, and a standard sample card will be used for comparison. Connection diagrams are printed on the casing ensuring that the user can always conduct tests correctly Let the side of test clamp with test piece face down, and put it on the test clamp base. After that, the bearing axle should be adjusted until it aligns and inserts the circular groove of clamp.

Martindale PD440S Proving Unit Technical Specifications

Wool felt (woven and non-woven upon request) can be used repeatedly and needs to be replaced if the surface becomes worn or soiled, and can be used on both sides. When using the Martindale tester, it is necessary to strictly follow the operating steps in the manual to ensure the accuracy of the test results. 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.

GB/T21196.2-2007 The abrasion and pilling resistance testing of fabrics by the Martindale method-part 2: measurement of specimen breakage;James Heal was part of the development of the original Martindale instrument in the 1940's and since then, there have been many variations of the instrument created to complete abrasion and pilling tests consistently and reliably. The latest design complies with the new standard relating to 2 pole voltage indicator, BS EN61243-3 and the requirements of GS38 Edition 4 2015. The latest version of BS EN61243-3:2010 came fully in to force in May 2013 and all voltage indicators on the British & European market should comply. The VI13800 replaces the industry standard VI13700. Abrasion resistance is how resistant a fabric is against other materials after experiencing constant friction. Select three corresponding total effective masses for the friction load according to the specimen use and fabric characteristics
