Abstract
Have you asked yourself how you will look over 15 years? At the Bosch factory in Jucu, we saw a time machine that can help you to travel for 15 years in the future. And the technologies used seem to have come from the reality of the next decades. This "time machine" is, in fact, part of Bosch's Engineering, Quality and Validation Laboratory (EQV). It's the test room, where the products are "aged" for 15 years to analyze how they can withstand the passage of time and the action of natural phenomena - storm, equatorial rain or frost. The EQV lab concept was created from the idea of synergy between R&D departments and production, a configuration that can provide a holistic view of Bosch products that are being analyzed from the initial development phase of the product until the product returns to the laboratory to investigate possible defects that occurred during their use. "We test the product's resistance to equatorial rain, for example. If it is an electronic component mounted on a machine that will go to South America and we know that there is very high humidity in that area, here we simulate the aging of samples in a more accelerated way, "explains Grasim Robert, head of the analysis group of the EQV lab. But they are not the only tests the products are subjected to. The water resistance of the samples is also done with a very strong 6 bar jet and the water has a force similar to that coming from a fire hose. Other tests check for resistance to different types of dust - for example, Arizona powder is more abrasive and worn plastic components, while ash-containing dust can lead to short-circuits - or saline mist, which activates corrosion mechanisms. In the climatic rooms, explains Grasim Robert, there are several parameters: Time, temperature and humidity. Depending on ISO standards and customer requirements, the test team varies these three physical parameters. There are tests that last for 10-12 months. In other words, a 15-year journey in the future still takes a few months, but taking into account the pace with which technology evolves, it is obvious that this duration is reduced.
Highlights
In the past, it has been a matter of setting up quality sections in each enterprise to check the quality of the parts manufactured before they are mounted on the machines to predict the problems of inappropriate parts or even scrapes that could have slipped on a car and spoil its new functionality or create a function beyond the indicated and desired parameters

Summary
It has been a matter of setting up quality sections in each enterprise to check the quality of the parts manufactured before they are mounted on the machines to predict the problems of inappropriate parts or even scrapes that could have slipped on a car and spoil its new functionality or create a function beyond the indicated and desired parameters. Non-destructive control devices have emerged and have been imposed in front of traditional control methods All these methods can not predict how that piece will behave, as a component of a machine, in its operation, dynamic, over time and when it will begin to wear out and deteriorate. It has become a question of wider control of important parts with dynamic operation with many repeated requests, control showing the ability of the piece to withstand in time Because this control should have lasted for years or decades, a time reduction method was used to force the task quickly with special vehicles, as if time would flow faster over it, the wear of the piece, is much faster while component track is checked, measured and used prematurely, intensively on a specialized machine
