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 […]
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?
Testing laboratories are constantly working to improve product quality. Thwing-Albert Instrument Company can help provide a single-source solution for updating and maintaining the testing machines used daily to verify that materials are meeting industry standards including ISO, ASTM, TAPPI and many others.
The capability to prepare test specimens accurately, efficiently and safely is critical to ensuring reliable and repeatable test results. Inadequate sample preparation can lead to additional retesting and higher costs while improper tools can endanger operator safety. The selection of the optimal sample cutter depends on a few key factors.
The loop tack test measures the contact tack of an adhesive tape that has been formed into a loop. The fixture meets the requirements for ASTM D6195, FINAT FTM 9 and PSTC 16. Â When used with the Vantage NX Universal Tensile Tester, a pair of grips hold the sample and the fixture during the test.Â
