In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied. Several tests measure the resistance of paints and coatings from substrates: cross-cut test, scrape adhesion, pull-off test , and others.
A soil test is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture.
The adhesion of the soil textural components by organic substances, iron oxides, carbonates, clays, and silica, the breakage of those aggregates from expansion-contraction caused by freezing-thawing and wetting-drying cycles, [21] and the build-up of aggregates by soil animals, microbial colonies and root tips [22] shape soil into distinct ...
The power of adhesion allows these organisms to be able to climb on almost any substance. [2] The exact mechanisms of arthropod adhesion are still unknown for some species, but this topic is of great importance to biologists, physicists, and engineers. [2] [3] [7] These highly specialized structures are not restricted to one particular area of ...
We’ve been using paint dots for 25 years or so now, so some trees have several paint dots on them.” Pruning and treatment dots also give a heads-up to property owners near the trees.

A test patch should be as clean as possible. Contamination of a patch can influence the results significantly. Bresle patch injected with 15ml water as in ISO 8502-6 Annex A. The ISO 8502-6 standard prescribes in annex A that certified patches shall be used. This annex describes a stress test to ensure patch adhesion and wash ability.
