ASTM D689-Standard Testing Instruments

ASTM D689-17 specifies the standard test method used for determining the internal tearing resistance of paper through the Elmendorf-type apparatus. The standard assists manufacturers' research into tear strength and fiber bonding behavior as well as the durability of the paper materials under controlled laboratory conditions. It is also employed throughout industries in paper, printing, packaging, and paperboard to analyze material toughness, tear propagation resistance, and product quality. ASTM International Presto Laboratories offers advanced tearing strength tester systems suitable for ASTM D689 testing applications. These testing systems help industries measure paper tear resistance, material performance, and product consistency for laboratory analysis, quality inspection, and production quality control requirements.

Tearing Strength Tester

Tearing Strength Tester

Tearing Strength Tester is a consistent tool useful to determine the tearing strength of fabrics, plastic films, and similar materials. Tearing Strength Tester is the tensile force required to rupture a pre-slit sample under controlled test conditions.
Tearing Strength Tester HMI Model

Tearing Strength Tester HMI Model

Presto has recently launched a tearing strength tester HMI model that is manufactured in a state-of-the-art lab and is designed for the tearing resistance of paper, thin film, ventilation tape, and other materials. We have designed our equipment to make advanced calculation methods that make sure precision test with reliable repetition. The equipment is installed with a high-speed programmable logic controller system that provides features such as auto testing, calculation, and analysis result.
