Universal Wear Tester Stoll Quartermaster GT-C15

Versatile Multi-Mode Abrasion & Wear Resistance Tester for Fabrics, Footwear & Industrial Textiles

1. This quartermaster universal wear tester equipped with accurate loop counter and timer. Digital counter can record the cycle index when the sample ruptured. And testers can preset the counter to stop before sample rupturing. Count down model can also be used in count the cycle index.
2. To ensure accuracy of the rubber membrane when doing the surface abrasion test, this machine equipped with accurate pneumatic pressure control system.
3. Stoll Quartermaster Universal Wear Tester: test can be done automatically which can ensure not only the accuracy of repeat test result but also save operator’s time.

Q1: What core test modes can be performed using the GESTER GT-C15 Universal Wear Tester?

A: The GT-C15 is a versatile 4-in-1 wear testing machine. By switching test heads, operators can perform:

1. Surface abrasion (inflated diaphragm method per ASTM D3886)
2. Flex & fold abrasion (per ASTM D3885)
3. Flat abrasion and frosting (per ASTM D3514 / AATCC 119)
4. Edge and crease abrasion testing.

Q2: How does the GT-C15 detect sample rupture during flex or surface abrasion testing?

A: The machine features an automatic electrical contact/rupture sensor system linked to the digital LCD counter. When the specimen tears through or all warp/weft yarns break, the sensor triggers an immediate system shut-off, locking the precise number of double-stroke cycles on the display.

Q3: What is the purpose of the pneumatic inflation diaphragm in surface abrasion testing?

A: The rubber diaphragm provides an elastic, uniform contact surface beneath the specimen, simulating the multi-directional pressure and contour stretching experienced by garments and footwear during real-world movement and rubbing.

Q4: What standard accessories are included with the GT-C15 package?

A: The standard package includes: Tension weights (5 pcs), Press weights (5 pcs), Flex abrasion fixture and blade device (1 set), Surface abrasion head assembly (1 set), Edge/fold abrasion clamp, micrometer calipers, power line, and initial abrasive paper supplies.

Q5: What routine calibration and maintenance should be performed on the GT-C15?

A: Regularly verify the pneumatic pressure regulator reading against a calibrated external pressure gauge. Ensure the reciprocating slide guide is lubricated monthly. Check rubber diaphragms for micro-tears or loss of elasticity before starting ASTM D3886 testing batches.
