MACHINERY – TESTING | TECHNOLOGY FATIGUE TESTING Automated specimen handling for DMA
Metravib, a specialist in dynamic mechanical analysis, has improved DMA and fatigue testing by extending the capabilities of its DMA+ series. Its Xpander is an automated specimen handling system that is designed to boost the productivity of the DMA+ series and can provide tests round the clock in compression, tension and shear. The DMA+ series testing

Tablet brings ease of use to materials testing regimes
Lloyd Instruments has introduced a new tablet for use with its LD Series of materials testing machines – with capacities ranging from 5 to 100 kN. The tablet is designed for users who are looking for an easy, reliable digital materials testing solution where no computer or knowledge of programming language is required. When combining the tablet with an LD Series materials tester, the machine is turned into a standalone test machine that loads all data directly into the tablet. The 2-in-1 functionality of the tablet offers the user the flexibility of placing the tablet directly on the test machine or unattached next to the machine. With an intuitive
interface and quick test functionalities – such as defining specific tests as favourites on the start-up screen – setting up a test,

capabilities are extending with a brand new Multitest crack growth software module coupled to a motorised video camera.
Using specimens up to 80mm wide, it is possible to follow up to four cracks in one single test. The crack length measurement can be performed with a resolution better than 2 microns. “Xpander and the new DMA+ series have been designed taking account of
industrial expectations in terms of accuracy, performance, productivity and ergonomics, as expressed by worldwide leaders in the rubber and polymers sector. “With 50 years of experience in the
field, we are the ideal partner,” said Hugues Baurier, worldwide sales manager. �

CHEMICAL ANALYSIS
Screening samples for
phthalates Actus Analytical has developed an FTIR method to screen polymer samples and detect ortho-phthalate plasticiser to levels of 0.1% (1000 ppm). The method is
selecting test runs, and exporting results takes only a few keystrokes. The 13in tablet features
an easy-to-read, colour touchscreen and is aimed at routine applications requiring the measurement of peak loads and breaking loads. Test results can be viewed either as a graph or in a tabular format showing multiple test results. The results are automatically saved, offering the user the ability to recall them at a
later time to analyze or continue testing a batch run. Test results can be
exported into both PDF and .csv files. Data storage can be done internally or on an external server, to provide an efficient way of documenting yields, product quality, and performance. The tablet can be
password protected and features two levels of user access: supervisor and operator. �

positioned as a quality control tool to allow processors to quickly determine whether or not a sample contains an ortho-phthalate. FTIR is well suited for this kind of quality control tasks, says the company, because it is a non-destructive, simple, and inexpensive test that gives immediate results. In addition, the chemometric model allows its use by non- technical personnel. The technique was developed for the Agilent 4500 FTIR, which the company says is well suited to the task due to its power and patented permanent calibration. �
