A universal testing machine (UTM) is a piece of equipment used by manufacturers to test the properties of various materials. UTMs are also called universal testers, material testing machines or tensometers. Manufacturers adapted the term “universal” because of the machine’s versatility in meeting various industry quality standards like ASTM or ISO. Basic UTM Testing Methods Read More »
A Universal Testing Machine (UTM) measures how materials respond to forces such as tension, compression, bending, or shear, identifying when a sample deforms or fails. Widely used in manufacturing, research, and quality control labs, UTMs can test a variety of materials—including plastics, metals, rubber, films, textiles, adhesives, and packaging—by swapping grips, fixtures, and accessories to Read More »
One widely recognized method of measuring the tear strength of paper is the Elmendorf tear test, which provides a standardized way to quantify how well paper withstands tearing forces. The test gets its name of the inventor, Armin Elmendorf. Thwing-Albert Instrument Company offers a wide range of Elmendorf tear testing equipment — specializing in precision testing machines used to measure the Read More »
The Elmendorf tear test is a standardized method for measuring the tearing strength of flexible plastic films, paper, textiles and nonwovens once an original tear has been made — called the propagation of tear. It provides a quantitative measure of the force required to propagate a single tear through the material. Thwing-Albert Instrument Company is Read More »
The testing instrumentation that you use in your R&D laboratories and quality control departments is integral in product develop and ongoing quality assessment programs. We know that this is often a capital investment. Careful consideration needs to be undertaken when the time comes to adding capability or upgrade legacy instrumentation.
Don’t let your testing fall behind. Unforeseen delays are impacting many industries due to a variety of factors. Sometimes it may be labor, sometimes parts, sometimes raw materials. Whatever the cause, it is important to be prepared for the future.
Learn about some tips for the selection of grips and fixtures for use when testing with a Universal Materials Tester like the VantageNX or the QC-3A. This is one of the most important accessories because your samples need to stay in place during a test in order to be valid along with keeping your quality lab safe.
The terms peel and seal strength are sometimes used interchangeably when describing a material’s adhesion properties and the appropriate test methods to accurately test and measure this property. In reality, these terms are distinctly different when it comes to materials testing. Specific testing protocols should be followed to ensure accurate and comparable data.
Are your laboratory instruments providing you with the accurate measurement data you require? If your company hasn’t had a Preventive Maintenance Inspection (PMI) performed on your instruments recently then the answer may be no. Why take the risk?
