The BET surface area of the 2–2.8 mm granules was determined by applying the standard Brunnauer–Emmet–Teller method to the nitrogen adsorption isotherms obtained at −196 °C using the Micromeritics ASAP 2020 instrument. To test the compressive strength of the as-synthesized granules, about 20 granules (2–2.8 mm in diameter) were ...

We will look at a very easy experiment that provides lots of information about the strength or the mechanical behavior of a material, called the tensile test . The basic idea of a tensile test is to place a sample of a material between two fixtures called "grips" which clamp the material. The material has known dimensions, like length and cross ...

The testing instrument is sufficiently best to decide the genuine nature of the material. The gadget involves a round and hollow cavity warming barrel in which 5 grams of granules are embedded at a particular temperature and jabbed inside for the liquid condition of the plastic. The MFI of the plastics is ascertained with the accompanying recipe:

There are two main ways that these can be tested – in a 'bulk' test in the Granule Compaction Rig, or by testing a single particle at a time during a cylinder compression test. Granule testing is important to provide an indicator of the tableting potential of some materials, or a measure of friability or compaction strength of granules.

Highest granule strength is apparently obtained with a yielding/plastic interface and results in a strong flexible particle as shown in FIG. 10 H. An interface with a brittle material appears weaker as shown in FIG. 10 G. From the foregoing examples, stress strain data have been obtained for a large set of experimental granules.

I am aware of, and use, the weak instrument robustness test developed by Finlay, Magnusson and Schaffer, 2013, but I have been advised to report results for test of instrument's strength. Also, if I use the twostep option with ivprobit, would the F-statistics obtained work for this purpose? Please advise. Thanks a ton in advance.

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.

The F-test you refer to also is related to the first stage, i.e. the regression of your endogenous variable on the instrument(s) and the exogenous variables. In case of one instrument, the F-statistic is the t-statistic squared. As a rule of thumb you should be worried about weak instruments if your F-statistic is below 10. The reference is
