The use of forced calibration grew out of disasters that occurred at the end of the 19th century and the beginning of the 20th. At the time, boilers were being used for heating and supplying power. Though they were made of heavy steel, the boilers would reach a high pressure point that caused them to explode. The results of the explosions were damage to property and multiple casualties.
There were tests available at the time that determined the strength of the metals used in boilers. Unfortunately, the design and implementation of the tests produced inaccurate data and tainted readings. The rising number of catastrophes and deaths led engineers to develop more accurate measures for determining the capabilities of materials. The result of which was the creation of a variety of tests referred to as forced calibration.
What is Force Calibration?
It is not possible to fit forced calibration into a single simple definition since its name encompasses an array of tests, experiments, and observations, from pounding on metal to pulling materials apart. In general, forced calibration quantifies the amount of concussive or stressful force that can be applied to an object before the object fails. The data from the research assists manufacturers in determining the performance of their products and the product’s life.
In the process of deciding the capabilities of a product, the product may be put through a series of tests, each of which is designed to break or strain it. Though the vision of forced calibration may engender an image of pounding on metal, the technological aspects of forced calibration go far beyond the simple striking of metal.
Types of Force Calibration
All materials endure some form of force during their use, even if it is the simple force of gravity. For the purposes of products and equipment, the amount of force a product can sustain during its use needs to be measured, cataloged, and calculated to ensure its proper and efficient performance.
The perfection of calibrating equipment began during the boiler disasters at the turn of the 19th century. Over the years, new and innovative methods have been perfected to measure the properties and qualities of nearly every item sold or used. The most common types of measurements are tension, compression, hardness, and impact. The design of each of these types of calibration is perfected and configured to measure the properties and characteristics of nearly every product.
Force Calibration Equipment
Strangely enough, some of the equipment used to measure various types of force are rather common, such as a handheld scale pulled against an object. From these simple devices, the types of calculation equipment become more complex and includes hydraulic presses, force gauges, and tension dynamometers each of which provide precise and accurate data down to the slightest detail.
A key component of calculating equipment’s endurance is a load cell that converts mechanical energy into electrical signals, which are used as data for determining the potentialities of the tested item. A load cell compares the readings of a known device to that of an unknown one. The purpose of the comparison is to categorize and describe the unknown device.
Every item that is sold, used, manufactured, designed, or produced is first put through a series of tests to measure its strength, endurance, and breaking point. The main purpose of these stressful tests and calculations is for the safety and protection of users.
