Roush opens Advanced Durability Lab19AUTP10_1210/1/2019
The auto industry's steady march toward electrified and automated vehicles has many suppliers affixed to the digital-testing environment rather than using traditional hardware validation. With a six-degrees of freedom road simulator as its centerpiece, the recently-opened Roush Advanced Durability Lab in Livonia, Michigan is a trend-buster. “If suppliers and vehicle manufacturers aren't going to reinvest in certain hardware solutions because their product-development focus is software solutions, there will be a gap. That's an opportunity for us,” claimed Jeff Johnston, Roush's president of testing services.

Guide to Package Integrity & Validation Testing under ISO 11607 and MDRTBMG-350859/1/2019
Updates to ISO 11607, Parts 1 and 2, have left many medical device manufacturers wondering about the future of their packaging designs. These changes come at a stressful time for OEMs, as Europe is also in the process of replacing the current Medical Device Directive (MDD) with the Medical Device Regulation (MDR) in 2020. The interplay between ISO 11607 and MDR is complex, and it’s difficult to predict regulators’ plans for enforcement.
Got Your Game Plan? The OEM Playbook to Navigating Preclinical Device Testing Under MDR and ISO 10993-1TBMG-337352/1/2019
When the Medical Device Regulation (MDR) replaces the Medical Device Directive (MDD) in 2020, requirements for medical devices in Europe will present greater regulatory hurdles. In addition, ISO 10993-1, created by the International Organization for Standardization (ISO) Committee and mandated by both the FDA and MDR also introduce new requirements for pre-clinical safety device testing. Medical device manufacturers are feverishly working to navigate the changes and develop their preclinical device testing strategies to overcome what's not just a regulatory hurdle, but a business challenge.

Inter-Laboratory Combat Helmet Blunt Impact Test Method ComparisonTBMG-327268/1/2018
As the medical community learns more about brain injury, the importance of blunt impact mitigation becomes more apparent. As such, it is critical to make sure that research labs are not only capable of performing testing in this field, but also show inter-laboratory consistency and reproducibility. This study is a comparison between the two validated blunt impact testing labs (Aberdeen Test Center (ATC) and National Technical Systems (NTS) Chesapeake Testing Services (CTS)), and Natick Soldier Research Development and Engineering Center (NSRDEC).
Modular and Open Test Bench Architecture for Distributed Testing2017-01-21179/19/2017
Currently, aircraft system Test Benches are often proprietary systems, specifically designed and configured for a dedicated System Under Test (SUT). Today, no standards for configuration, data communication, and data exchange formats are available for avionics Test Benches. This leads to high Test Bench development costs and redundant activities between aircraft system suppliers and airframers. In the case of obsolescence issues for test system components, it is very costly to replace the respective parts as a high integration and reconfiguration effort is required. In the scope of an R&T project, involving several test system suppliers and aircraft system suppliers as well as Airbus as an aircraft manufacturer, a generic and modular architecture for an open test environment is under development. A further goal of the Virtual and Hybrid Testing Next Generation (VHTNG) research project is to prepare a set of open standards for the interfaces to this architecture. The modular architecture is designed to provide a win-win situation for suppliers and customers alike, driving innovation in Test Bench development and utilization. This distributed architecture is able to support real and virtual testing, and is scalable from equipment to aircraft level. During the course of an iterative and incremental development process, collaborating with all industry partners, a technology demonstrator successfully showed that the functionality of integrated modules from multiple partners could be proven against realistic aircraft system test use cases. As the project continues, further functionality will be added, communication performance between modules will be improved, and the currently implemented interfaces will be brought closer to an open standard.

Medical Device Testing: Start With a Strategy and PlanTBMG-81317/1/2010
Most medical device manufacturers must first receive approval from the U.S. Food and Drug Administration (FDA) before they can market a medical device. Device manufacturers must demonstrate that their device is safe and effective for the intended application. The tests that must be performed vary with the device, application of the device, and components of the device, such as coatings, as well as the length of time that the device may be used in a patient. To prevent delays in the FDA review process, manufacturers must ensure that they complete the necessary tests and avoid wasting time on tests that are not required or do not add to the assurance of safety of the product.
Less Is “More”: Can You Trust Your Ears II2000-01-00783/6/2000
In a 1998 SAE presentation Richard Stroud of Delco Electronics showed that ‘more’ of anything related to audio (loudness, equalization, et. al.) is often considered to be ‘better’ by untrained listeners1 This paper discusses the human mechanisms that influence the effect and concludes that independent professional evaluation is the best alternative for preserving quality of listening evaluations.

A Study of the Color Change of Automotive Coatings Subjected to Accelerated and Natural SAE Weathering Tests for Exterior Materials Durability9408563/1/1994
Exposure of automobile exterior materials such as coatings in the South Florida environment has become the de facto standard for testing their durability. In the early thirties, testing sites were established in this location by the automotive industry. Each automobile manufacturer applied different exposure techniques for their own acceptance criteria. SAE J1976 was developed in 1989 to standardize the various exposure types, however, the document still contains radically different test rack designs. Even though the Florida exposure tests have not changed extensively the coatings have become much more durable. Today's service life expectation of more than 5 years means that the coating cannot be tested to failure in the Florida environment and allow the developer to bring a new technology to the marketplace in a timely and competitive manner. This has led to the use of accelerated tests to speed up the exposure process. There are several alternative tests specified by SAE including xenon arc Weather-Ometer® (SAE J1960), Fresnel reflector device (SAE J1961) and fluorescent testing device (SAE J2020). The study reported here was carried out to draw conclusions regarding differences between the outdoor test racks designs and their relationship to the accelerated test methods, in order to identify the accelerated test providing the best correlation to Florida. Specimens were donated by three automotive coating manufacturers, representing a combination of coating types and colors in the form of coated test panels. Seventy specimens were exposed per test method. Performance evaluations including the measurement of color, were conducted several times during the exposure testing. Comparative color change data is reported for all of the test methods and statistical comparisons are made between each. the results showed that the best correlation was achieved when the light source most closely matched sunlight. All of the outdoor tests correlated well with each other.

Microbiological Certification Requirements for Non-Human Research on Space Station Freedom9214167/1/1992
Space Station Freedom offers an opportunity to study in depth the long-term effects of microgravity on the basic biology of animals and plants, an area of great importance to the permanent presence of man in space. NASA has long recognized the significance of spaceflight research using non-human biospecimens in understanding these broad aspects of gravitational biology. To this end, plants and small animals have flown on manned and unmanned missions since 1965, including the highly successful Spacelab Life Sciences-1 (SLS-1) mission in June 1991. To minimize the potential for problems related to the inflight exchange of microbes between crew members and research biospecimens, NASA has established a policy of microbiological certification of animals designated to fly on NASA manned missions. The Human Research Policy and Procedures Committee at the Johnson Space Center administers this policy. Spacelab-3 (May 1985) and subsequent Shuttle flights involving animals have provided valuable experience with these microbiological requirements. The successful verification of the Research Animal Holding Facility (RAHF) on SLS-1 has demonstrated the ability to successfully house small animals on-orbit and has prompted a review of the current microbiological certification policy. It has become clear that quality standards and streamlined procedures must be adopted to efficiently accommodate increased numbers of flight research animals. This is especially true as the Space Station era begins and animals are continuously present aboard Freedom. This paper presents a brief history of the NASA microbiological certification program, its current status, and some suggestions for program improvement. In addition to increased efficiency and effectiveness of the certification process, program improvements may lead to more efficient on-orbit experiment and maintenance operations, reduced potential for microbiology-related launch delays and experiment constraints, and enhanced scientific return from Space Station Freedom.
