FEV and the Art of EV Testing20AUTP10_0110/1/2020
The legendary powertrain-engineering group has expanded its global footprint into EV testing and development to keep pace with changing technologies and customer demand. Before the impending flood of electric vehicles (EV) expected for the 2025 timeframe enters the market, every one of them - and their subsystems - must be fully tested, validated and calibrated. Companies specializing in engineering, design and testing services are making significant investments to meet industry demand in this already-booming field. One of them, the Aachen, Germany-based FEV Group, has expanded its global footprint into the electrification-testing realm in a big way. Famous for its powertrain-development competency, FEV recently added a 12,000-m2 (∼130,000 ft2) facility dedicated to testing batteries, electric drives and related components. Dubbed eDLP, the complex is among the largest test facilities in FEV's global network and claims to be the largest independent battery-test facility in the world. With a solarpanel array integrated into its full roof area, the new complex near the village of Sandersdorf-Brehna brims with resources for the comprehensive testing of cells, modules and complete high-voltage batteries.

Gaskets for Extreme Exhaust Test Applications2015-01-17404/14/2015
Gasket materials are utilized for various different types of high temperature testing to prevent leaking at bolted joints. In particular, the automotive test services field uses flanged-gasket bolted exhaust joints to provide a convenient method for installation & removal of exhaust components like catalytic converters for aging, performance testing, etc. Recent improvements in the catalyst aging methods require flanged-gasket joints that can withstand exhaust temperatures as high as 1200°C. Gasket materials previously used in these applications like the graphite based gasket materials have exhibited physical breakdowns, severe leakage, and general thermal failures under these extreme temperatures. In order to prevent these leaks, metal-reinforced gasket materials in a number of configurations were introduced to these extreme temperature environments to evaluate their robustness to these temperatures. A series of experiments were implemented to evaluate different flange and gasket material in this extreme test environment. The variables evaluated are as followed: gasket material, gasket thickness, flange material, and flange thickness. Responses evaluated were: reusability, effectiveness of seal pre/post exposure measured via cold leak rates, and the general robustness of the materials to these extreme temperatures. It was determined from this testing that in order to meet the desired leak requirements of 0.5 L/min@34.5KPa[5 psig] that 12.7 mm [½″] thick 304 stainless steel flanges and HT400 (0.080″) gasket materials would provide the best flange-gasket combination for overall robustness to extreme catalyst aging.

Eight Things to Look for in a Medical Device EMS ProviderTBMG-163935/1/2013
Today’s medical device OEMs live in an age of abundance: both abundant options and abundant regulatory requirements. With so many options and so many restrictions, it can be very difficult to select the right contract manufacturer (CM) or electronics manufacturing services (EMS) provider. So many factors come into play. What are their testing services? Do they have clean room capabilities? How do our corporate cultures mix? Will this be a long-lasting or one-time relationship? Could they help me with miniaturization?

Taking a deeper look at NDT10AEMD0811_018/11/2010
Rapid adoption of composites in aircraft has accelerated the need for newer and faster nondestructive testing methodologies. We look at some of the issues. Two trends have converged to make nondestructive testing (NDT) increasingly attractive to aerospace: widespread use of composites and the ever-increasing sophistication in ways to look below the surface of parts. NDT's obvious draw is its ability to evaluate parts without compromising functionality. Since composites bring an urgent need to see voids or lamination problems, it brings a corresponding need for more effective technologies to see into components. TÜV Rheinland of North America Inc. has gathered a stable of NDT companies under the aegis of its TÜV Rheinland Industrial Solutions, including Non-Destructive Testing Services Inc. and Unified Testing Services Inc.

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.

At your serviceAUTOJUL07_057/1/2007
As cost and human-resource pressures mount, testing and engineering outsourcing heats up and alters roles within the industry. Outsourcing in the auto industry is continuing to expand, creating significant growth for the companies that provide engineering and testing services. Automakers are starting to change the way they use outside engineers. While maintaining some of the constants that face engineers, they need to do more complex tasks in shorter time frames. Service providers are picking up many of the chores that come as downsized engineering staffs attempt to add features that help differentiate vehicles. As automakers become more comfortable with the idea of outsourcing design and testing, some are starting to change the way they work with these service providers.

Reducing Costs Associated with Validating ECUs and Systems in the Increasingly Networked Vehicle2005-01-12834/11/2005
Testing is an intrinsic, vital and on-going part of the product development process, particularly in the development of automobiles and automotive systems. Validation testing of vehicle electrical systems and their components is especially critical, and is expanding rapidly with the growth of electrical and electronic features offered in the automotive marketplace. In the face of this expansion traditional approaches to ECU and Systems validation are being seriously challenged by cost pressures in two areas: The cost of basic test equipment and test services labor costs, and the costs associated with the expansion of ECU I/O count and functionality in support of these features. The evolution of multi-featured in-vehicle networking from its basis as multiplex wiring has also expanded systems complexity dramatically, which has compounded the problem. Paradoxically, however, this new form of complexity can also reduce test requirements, hence test and validation costs, to a significant degree. The key to reducing test costs in increasingly complex systems is to exploit the ability of the distribution process to make each of the testable components in the system simpler.

An End-user's Guide to Commercial Vehicle Measurements: Interpreting Dynamic and Structural Tests Outside the Lab2001-01-271211/12/2001
Engineering tests that do not impact business decisions waste time, budgets and morale. This paper will consider input and output information for the test process-specifically in vehicle dynamics and structural integrity labs. Uncontrolled test processes are unlikely to fulfill expectations. Conversely, the process may be closely defined in a widespread specification, and yet not answer the question at hand. Potential downstream impacts of loosely defined technical details will be discussed. Topics include selection of transducers, recording parameters, filtering and analysis techniques. Physics of common environmental loading are presented, along with implications for both the test plan and later use of the test data. Case studies as both a truck, bus and railroad test services provider and consumer will be discussed.

Driven to testAUTOJUL01_017/1/2001
As automotive manufacturers and suppliers continually attempt to cut costs and reduce development cycle times, outsourcing of testing is becoming more prevalent in the industry. Producing a road-ready vehicle means components and systems must meet governmental regulations as well as performance targets. Although automakers and many Tier 1 suppliers rely on a variety of in-house test cells and testing equipment to confirm that products meet specifications, outside testing vendors are gaining business as vehicle manufacturers and suppliers take the budget axe to unnecessary capital expenses. Because idled test cells and testing equipment can be as hazardous to business profits as idled assembly plants, the best profit plan mandates full utilization of resources. As such, one of the increasingly popular cash-conservation alternatives is retaining an independent provider to oversee test operations. Known as asset management, this next evolution of outsourcing offers financial benefits and reserved access to specialized testing.

Diesel Fuel Properties and Additive Effects on Dl Injector Deposit Formation93273810/1/1993
A test was developed by the Cummins Engine Company to evaluate Diesel fuel quality and potential additive effects. This test utilizes a Cummins L10 Diesel engine with a PT fuel system and stepped plunger injectors. A modified CRC rating system is used to quantify deposit levels. This paper further investigates the L10 Injector Depositing Test and will focus on Diesel fuel and additive variables. In the original work, the bulk of the data was collected on an industry standard reference fuel, Cat 1-H, as opposed to commercially available Diesel fuels. Commercially available Diesel fuel varies in composition with regard to sulfur level, percent aromatics, final distillation end point, and cetane number. To evaluate these fuel properties and their possible effects on injector deposit formation, two test matrices were designed. The first experiment is a 12-run fractional factorial design with four factors: additive level, sulfur, aromatics, and 90 percent distillation point (T90). Several Diesel fuels were blended to achieve specific levels of the three fuel properties; these represent a range of fuel properties that can be found commercially. The second experiment, a six-run factorial design, evaluates the effects of cetane improver and additive level on deposit formation in a commercially available fuel. The first design was run at Engineering Test Services, while the second was completed at AutoResearch Laboratories; both used the procedure described in SAE Technical Paper #912331. The paper presents conclusions on various fuel compositional effects as seen in the L10 Injector Deposit Test. Additionally, the effects of the various additives and additive concentration are discussed. The use of designed experiments allows a discussion of the statistical significance of the effects of fuel properties on deposit formation in this test. This data, combined with Lubrizol's large L10 data base, will facilitate future test refinements and eventually help to evaluate the suitability of this test for future Diesel fuels.
