A necessity for the importation of a customer's vehicle into the US for testing at MGA is proper documentation. MGA is familiar with the documentation necessary to ensure all regulations are followed from importation to destruction. Depending upon the needs of the customer, the tested vehicle may take a few different paths. If the vehicle was imported, the vehicle must be either destroyed or exported. If the test vehicle was manufactured in the U.S., it may be shipped back to the customer or destroyed by MGA.
After testing is completed, MGA-WI uses a local scrap processor, Miller Compressing Company, for the destruction of the vehicle. Miller Compressing is one of the largest in the Midwest, and is located about 30 minutes from MGA-WI. They are environmentally responsible. Not only do they recycle the vehicles and scrap, but prior to crushing and shredding, they also remove all environmental hazards and recycle those items as well.
When the vehicle arrives at Miller Compressing, a customs officer checks the VIN to ensure the paperwork matches the vehicle that is to be destroyed.

Battery Failures - Part 1 External Short Circuits
Suzanne Phillips - Akron, NY (suzanne.phillips@mgaresearch.com)
Battery failures happen all the time, but none are more spectacular or dangerous than a fiery battery explosion. Explosions and fire are scary threats. Thanks to diligent development and testing, these displays are rare. In order to test batteries properly, we must understand what causes these types of reactions. All battery failures can be categorized into two types of reaction. The first is an instability that all battery materials have when they are heated to extreme temperatures. These types of failures are almost unheard of because the temperatures required to make the metals unstable usually cause another failure first. The second type of failure is short circuiting.
A short circuit can be caused by many things but the basic concept is the same. When the negative and positive terminals of the battery are brought together, the battery will rapidly discharge causing large amounts of heat and gases to be released. The short can be caused by something internal like the insulators being breached by extreme temperatures, and also by something external like a nail puncturing the cell. A third type of short can happen between the terminals by touching both terminals to an exposed piece of metal. At MGA, we test batteries for all of these types of failure. Let's take a closer look at how we test the third type of short circuit.
When externally short circuiting a battery, there are several useful pieces of information collected. The current and voltage of the battery are recorded over time for evaluation purposes, as well as the temperature of the battery's surface. Not only does this give us the temperature of the case, but it also acts as a good indicator of whether the battery will explode. Explosions are almost always preceded by a sharp increase in temperature. Once the temperature has peaked and starts to fall, it is less likely that the battery will explode.

South Carolina Testing Highlight:Thread Testing
 Seats, instrument panels, door panels and headliners are the main focus areas for interior testing but so are the threads that hold them together. Thread testing is key for air bag deployment and seat durability. Not only does thread play an important role in the automotive industry, but it is a factor from the clothes you wear to the luggage you travel with. MGA offers various thread testing services. The most common test that is conducted on thread is tensile strength and elongation. For tensile testing, special grips are used to ensure that the thread is not pinched or severed during testing. Tensile testing can be conducted after the thread is exposed to many environmental conditions such as xenon exposure, hot, cold, and humidity cycling as well as water immersion. Twist and twist balance are tests used to determine the twisting properties of the thread. We also offer mildew testing to evaluate the thread for mildew resistance after exposure to harsh humidity conditions. Color testing is another important step in thread testing. Crocking is used to determine color transfer, as well as dye migration and dye stability. These tests help determine the thread's resistance to transfer and rub off its color. Xenon testing is another color test for its resistance to fade or yellow in the sunlight. For more information regarding thread testing, or if you have any questions or comments, please contact Jennifer Hill at (864) 848-3088 or send an e-mail to jennifer.hill@mgaresearch.com. |
Up Close & Personnel
Tim Bratz, based out of WI, is a dedicated member of MGA's family. He has been a part of the family for four years. His expertise lies in conducting crash tests, calibrating dummies and instrumentation, and supporting our global equipment installations.
When visiting our crash facility, Tim may very well be the first person to greet you as he is in each day before 6:00 a.m. And you will most likely find him positioning dummies, preparing crash test vehicles, and conducting immunity driving events.
He recently trained engineers at the PATAC (Pan Asia Technical Automotive Center) Crash Facility in Shanghai, China on FMVSS 214 Moving Barrier & FMVSS 214 Pole Impact, Moving Vehicle to Moving Vehicle Impact, and performed an ultimate high speed verification of the tow system.
Beyond Tim's MGA duties and traveling the globe, he is a proud Irishman who plays drums in a metal band and enjoys working on ATVs in his free time.
Tim will continue in his growth and development. He always wants to know more and pushes himself to go above and beyond his expectations.

Its About Attitude
Traveling throughout the country, it has become apparent to me, that many people are overly concerned about the economic health of the nation. To me, this is somewhat similar to the situation during the late 1970's. That period of economic distress was followed by one of the greatest periods of economic expansion the nation has ever experienced.
Some people now talk about the Great Depression of the 1930's as though they lived through it. I was born during this period but have no memory of what it was like. I do, however, remember the World War II period of the early 1940's. Some economists say that the Great Depression ended with the beginning of our involvement in World War II. That may technically be correct, but if true, it was no way to end a depression. Out of a population of about 140 million people, over 10 percent of the most able bodied men and women were placed in the armed services. Most of the manufacturing was shifted to producing war goods.
Naturally, under these conditions, the country experienced full employment. Although people made good wages, there were little consumer goods that could be purchased. Cars and other consumer goods were not being made, and most commodities such as food and clothing were rationed. Those who owned a car were allotted 2 to 3 gallons of gasoline per week. As a result, the money earned was not spent, but used to buy governments bonds for funding the war effort.
As I remember, it was not until well after the war ended in 1945 that consumer goods became readily available. My dad was able to finally obtain a new tractor in 1949 and a new car in 1950. Yet, except for the war, these times were not bleak. My mother, in her later years, often remarked that this period, when my parents married and raised their family, was probably the happiest time of her life. This was likely a common attitude that many people had during that period of considerable economic stress.
