Parallelism 0.05mm Rubber Testing Equipment Weight 67kg Martindale Wear Meter

Martindale wear meter JD-3120A

product description:

Martindale wear-resistant instrument is designed to absorb the advantages of domestic and foreign similar instruments. Its appearance is elegant, the interface is easy to understand, and the operation is simple. The microcomputer system adopts two counting methods, which is intuitive and generous, easy to set, and four stations simultaneously. Test to improve test efficiency. The instrument also has two kinds of Lissajous (Lisajous) 24mm × 24mm, 60.5mm × 60.5mm motion track and a variety of accessories can be purchased, can adapt to a variety of test method standards. Martindale wear tester is suitable for: GB/T4802.2, ASTM D4970, ISO12945-2 and other fabric pilling test.

working principle:

Martindale wear-resistant instrument principle: the circular sample and the same material fabric are rubbed with Lissajous graphic motion trajectory under a given pressure. After reaching the specified number of revolutions, the sample pilling grade is evaluated. Also applicable to GB/T13775, ASTM D4966, ISO12947 and other fabric abrasion resistance test. The principle: the circular fabric sample rubs against the standard abrasive according to the movement track of Lisajous curve under a certain pressure, causing the sample to be damaged, and the wear resistance of the sample is the wear resistance of the sample. performance.

Standards compliant:

Comply with: GB/T4802.2, ASTM D4970, ISO12945-2 and other fabrics pilling test.

Also in line with: GB/T13775, ASTM D4966, ISO12947 and other fabric abrasion resistance test.
