ASTM D1424 D689 ISO 13937 4674 Textile Fabrics Tear Resistance Testing Machine Digital Tear Strength Tester

ASTM D1424 D689 ISO 13937 4674 Textile Fabrics Tear Resistance Testing Machine Digital Tear Strength Tester 

Introduction

The tear Strength Tester uses the Elmendorf Tear Method to measure the force required for various sheet or film specimens to extend to a specified length under specified loads and cracks. It can detect the tear strength under impact forces ranging from 200 to 30,000 cN, with the impact force corresponding to a specific drop hammer. The instrument now cuts a tongue-shaped notch on the sample, and then measures the tear strength when the notch expands. The instrument is designed to be convenient and flexible, and can be used for various tests of both lightweight and heavy-duty samples.

Relevant standards

ASTM D1424/D689,NEXT 17,M&S P29,BE EN ISO 13937/4674,BS 4468 DIN EN 21974,GB/T 3917.1,ISO 1974

Scope of Application

The determination of the tear resistance strength for various woven fabrics (using the Elmendorf method) is carried out to test the impact tear strength of textiles, woven fabrics, non-woven fabrics, and coated fabrics. It can also be used for the burst strength tests of silk, cotton fabrics, various papers, cardboard, and single-layer and multi-layer corrugated cardboard.

Instrument features

1. Dual pendulum structure design minimizes resistance and provides higher testing accuracy;

2. Weighted base plate prevents shaking and offers better testing stability;

3. Flexible double spring fixture design enables easy and secure clamping of samples;

4. The lightweight weight loading tool makes loading heavy weights much easier.

5. The combined test weights can meet various testing requirements and have a wide range of test scales from 200cN to 30000cN. They can be used for testing the tear strength of different materials such as fabrics, papers, cardboard, plastic films, etc. The test units available include MN, CN, N, G, KG, OZ, LB.6. Touch screen interface for easy operation. Safety latch locks the heavy weight during testing start and end to ensure operational safety；

7. Equipped with PC interface for connection to PC, which can record and statistically analyze test results, with the function of exporting in EXCEL table format, and can automatically print test reports.
