Resistance Testing

EC = Erichsen cupping, FT = film thickness, HK = Konig pendulum hardness, MEK test = resistance to butanone, and Peugeot test = premium-grade gasoline resistance.

Do not test resistance on components while they are mounted on a circuit board The multimeter applies a current to the component being tested. That current may also flow to other components on that board, thus damaging them. 

Ensure the containment of experimental field strains when testing resistance management strategies. 

The first recommendation for integrated irradiance and spectral distribution of simulated solar radiation — especially for testing purposes — was published in 1972 as the publication of Commission Internationale de L Eclairage (CIE) No. 20. The listed spectral energy distribution was given in 40-nm steps up to 800 nm and included the infrared part of radiation up to 3000 nm. The maximum value of total irradiance has been specified for testing resistance of technical objects to deterioration. As an international criterion for comparison of artificial sources with natural daylight, specific spectral data more precise compared with CIE No. 20 have been published in CIE No. 85 1989 and are widely used today as a basis for simulation.

Stoll-quartermaster universal ware tester n. A versatile testing apparatus for measuring wear resistance of fabrics, yarns, thread, etc. It can be equipped with either of two testing heads, one for testing abrasion resistance of flat surfaces and the other for testing resistance to flexing and abrasion. 

Insulation tests—resistance between windings and shell of the unit. 

A similar classification has been adopted in B.S. 1344 (Part 2) but the time of exposure to the 10% citric acid is 20 min and the temperature is 20 °C. BS 1344 Pt 3 tests resistance to H2SO4 other parts test resistance to hot acids, alkalis and detergents. 

D-1876. Test Method for Peel Resistance of Adhesives (T-Peel Test). Tests resistance to peel separation in joints between two adherends which are flexible enough to deform into the T configuration (Fig. 14) without cracking or breaking (e.g., thin laminated aluminum sheets). 

This problem did not seem to be dependent on the salinity or velocity of the injected water, but did seem to be related to the presence of field crude oil. For this reason, refined oil was used in the tests. Resistance factor (RF) measurements made on essentially stable core samples showed that RF was roughly comparable in sandpacks and in cores ranging in permeability from 600 md to 3,500 md. 

While many products on the market claim to be cut-resistant, they don t offer protection from the variable nature of hazards in the workplace. This claim of cut-resistance is made based on industry tests like the EN388 and ASTM F1790, which only test resistance to straight and circular blades. These tests do not account for things like metal burrs, wood slivers, glass shards, and angled blades that are commonly seen in the workplace.
