Scope of Application

【Operating Instructions】

Used for determining the breaking strength and elongation at break of single yarns, synthetic filament yarns, and textured yarns. Controlled by a PC, the test process is fully automated.

**YG023C Single Yarn Strength Tester**

**【Scope of Application】**  

Used for determining the breaking strength and elongation at break of single yarns, synthetic filament yarns, and textured yarns. Controlled by a PC, the test process is fully automated.

**【Method Standards】**  

GB/T 3916, GB/T 14344, ISO 2062, ASTM D2256, etc.

**【Instrument Features】**  

1. The instrument can display three different tensile curves (F/L, F/T, L/T) as well as a composite curve, all of which can be printed.  

2. Controlled by a computer system, it automatically processes data, displays results, and supports printing. Data can also be saved to the hard drive for future retrieval.  

3. Uses the Constant Rate of Extension (CRE) testing principle.  

4. Features minimal connectors, no relays, and high reliability — ensuring accuracy, stability, and high efficiency. Parameters are input via a standard keyboard. The servo motor system ensures precise tensile speed control.
