The GenElm Series Elmendorf Tearing Tester is a laboratory instrument for measuring the tear resistance of flexible materials using the falling pendulum method. It determines the energy required to extend a pre-cut slit and complies with major international standards, including ASTM, ISO, DIN, JIS, EN, CSA, BS, APPITA, NF, and retailer-specific methods.

The tester applies to many material groups: plastic films, laminates, packaging foils, tissue, printing paper, wrapping grades, cartons, boards, woven and knitted fabrics, coated and laminated textiles, upholstery, technical fabrics, and nonwovens such as wipes, filters, geotextiles, and medical disposables.

Two versions are available. The 64 N model is suited for lighter papers, films, and standard textiles, while the 128 N model extends capacity to reinforced and technical fabrics. Both models use fixed geometry with a 7.0 mm clamp gap, 20 mm slit, and 43 mm tear distance to keep results consistent.

Main functions include pneumatic clamping, automatic specimen cutting, interchangeable pendulums, touchscreen control, onboard statistics, and RS232 data export. These features make the GenElm Series practical for quality control, production testing, and research, helping manufacturers validate material durability, compare batches, and comply with industry requirements.
