An Overview on Automated Test Equipment

Automated Test Equipment (ATE) is computer controlled equipment that is used for testing the performance and functionality of electronic devices or even help in subassembly of electronic components, PCBs or PCAs. Furthermore, ATE is used to perform stress testing which involves minimal human interaction. ATE performs tests on a device, known as the Device Under Test (DUT). This device is very efficient in measuring the performance and evaluating the test results. DUT is physically connected to the ATE through a machine called a Handler or Prober and a customized Interface Test Adapter (ITA) that helps in familiarizing the ATE's resources to the DUT.

In this process the steps are repeatable, consistent and faster in comparison to the manual processes. It is a great advantage of technology to mankind which is making the testing process much simpler and faster. Most of the smart manufacturing companies have adopted this methodology which has proved really beneficial to them. Earlier it used to take several hours to perform testing of an electronic device but now with the automated test equipment the same task is done in few minutes. Due to this reason ATE is considered to be cost effective and efficient electronic testing equipment which is ideal for high volume testing.

The Correlation Curve Of A Rebound Hammer

A rebound hammer is primarily used to assess the uniformity of concrete strength within a structure and to localize areas of inferior quality.

When using a rebound hammer to estimate in-situ compressive strength, the reference curves provided by the manufacturer must be used with some caution. The correlation between rebound number and compressive strength is very much dependent on the concrete mixture under test. In order to obtain an estimate of in-situ compressive strength using a rebound hammer in accordance with major standards, a calibration is necessary. The recommended method is to correlate the rebound hammer measurements with destructive tests made on core samples, or cubes/cylinders made from the same concrete mixture as that used in the structure.

Please refer to the following standards and guidelines for details of the requirements for creating such a correlation curve: EN 13791 (Europe), ASTM C805, ACI 228.1R-03 (North America), JGJ T23-2001 (China).

The resulting data is used either to shift a reference conversion curve or to define a custom curve for that particular mix. Typically the curve is defined to provide a safety margin to take into account the various factors that may affect the in-situ tests. EN 13791 recommends the use of a lower 10th percentile curve. This means that 90% of the data pairs lie above the curve and only 10% lie below.

Industry Feature: Addressing the industry need to create a concrete test hammer that can deliver accurate readings on virtually any concrete from any direction, on any surface without the need to compensate for impact direction, Switzerland-based Proceq announced today that it has launched the new SilverSchmidt concrete test hammer

How to Utilize a Rebound Hammer Properly

The rebound hammer was the first hammer that was created to measure the properties of rock or concrete. There are different versions of the hammer and this enables the company to provide the type of hammer that all customers want for whatever specific job they are doing. The hammer tests the surface hardness of concrete, and although some people believe that this can be converted to compressive strength, this is not acceptable.

The test for the acceptance of concrete must be carried out with different equipment. If the rebound hammer is used, the reading will not be correct and there may be serious consequences later on. The test results can be altered by a number of factors. Moisture content and surface smoothness are just two of the factors that can change it, and they test can only give an estimate of concrete strength.

The manual-testing tool is the instrument used for testing hardened concrete. This does not damage the concrete in any way, and it is an easy piece of equipment to use. It quickly assesses the results and is the most popular way of carrying out this test. Also known as the Schmidt or Swiss hammer, it carries out a very important function. While it is a good instrument to use, it cannot be used in isolation.

Cold Climates - The Ultimate Testing Ground For Floor Coatings

The garage floor in cold climates are subject to extreme temperatures, freeze/thaw issues and de-icing salts making it the ultimate testing ground for floor coatings.

De-Icing Salts

De-Icing salts might reduce slippage on roads and walkways but they cause significant damage to the concrete garage floor.. When you drive the salts get into the wheel wells of your car or truck and freeze in place temporarily. When you pull into your garage the salts start to melt the frozen snow and ice. The water that drips from your vehicle liquefies the salts that get into the pores of the concrete as well as the surface, starting a rapid deterioration of the concrete. As the concrete gets saturated it creates humidity and makes a home damp and cold. Not to mention mold buildup and deterioration of the drywall and beams of your home.

Spancrete Construction

Many homes have been built with spancrete construction. This is precast concrete panels that may be 24 -30 feet long, 3 feet wide and six inches thick. They are placed on foundations during construction and become your floor. In the home hardwood, tile and carpet covers the spancrete panels. In the garage concrete is poured about 4 inches thick over the spancrete which is also over your garage. As your home settles cracks form in the concrete above where the spancrete panels abut each other.

A Brief Background of the Schmidt Hammer And Its Uses

The Schmidt hammer is not a hammer as we normally think of it as normally a hammer is a wooden handle with a metal bar at the top used just to hit things very hard. There is no skill required and in the wrong hands, they can be dangerous. Ernest Schmidt invented this hammer in 1948. Ernest was a Swiss engineer. The role of that appliance was to carry out tests on rock and concrete. The tests carried out will let the user know the surface hardness and penetration resistance.

The Silver Schmidt tool is a new and improved product, and has many benefits missing from other hammers. Problems had been identified with existing hammers and these included the fact that impact direction had a direct effect on the rebound value, and a less than perfect reading is given. Friction within the wall can also play a part in affecting the reading. The final problem that could cause lack of accuracy is how well the tool is sealed. Silverschmidts new design sorts out these issues, and as a result, tests are now quicker and even more accurate.
