NTS Services Spotlight: Reliability EngineeringSpecialists in Reliability | “One Life” | HALT | Fault Analysis

Reliability Engineering ProgramNTS offers a Reliability Engineering Program as part of its Engineering Services which focuses

on design for reliability, “One Life” reliability and HALT testing, fault analysis, identi� cation and

corrective action. NTS has consulted clients in industries including aerospace, military, medical

device, consumer products, manufacturing, oil production and others. No matter what step in the

lifecycle the product is in, NTS has a reliability solution to improve product performance.

Our Services

Accelerated life testing to identify design, material, component or manufacturing related problems or inadequacies

Demonstration of product behavior in various circumstances or environments

Demonstration of “one life” or product warranty life and determination of MTBF and MTTF (Mean Time Between Failure and Mean Time To Failure)

Reproducing failures experienced in the � eld and developing fault trees to pinpoint failure mode and root cause

Ability to reproduce environments, in order to formulate bona-� de third party expert opinions

Successful relationships with regulatory agencies such as FAA, FDA and NHTSA, as well as standards committees across many industries and disciplines

One-Life and HALT TestingOne-Life testing relies on producing a use life pro� le. Once the pro� le is identi� ed (which includes

thermal, dynamic, vibration and other stress producing environments), our reliability group will

develop an “accelerated pro� le” which addresses all of the damage elements of “One-Life”, while

reducing the test time to substantially smaller intervals and determine the Mean Time Between

Failure (MTBF) or Mean Time To Failure (MTTF).

NTS is also well versed in classical HALT testing and has capabilities to develop classical HALT

test procedures. NTS has several HALT chambers throughout the facilities. The practice of

accelerated aging or HALT testing allows product designs and manufacturing technologies to be

validated for both robustness of design concurrent with the integrity of the parts, circuits, boards,

enclosures and manufacturing. Warranty durations can be determined through accelerated life testing.

Fault Analysis and Reliability Forensic ServicesFault analysis and identi� cation is completed using Fault Tree methodology and root cause

analysis with the application of testing and proof of concept. Corrective action recommendations

can be made for reliability improvement and additional testing can be completed to ensure

reliability issues have been mitigated.

NTS has also been a valuable partner to its customers in providing reliability forensic services

in areas associated with product liability science, and associated expert witness requirements.

In this manner, NTS reliability engineering is a full product life cycle service, spanning across

designed in reliability assurance at the front end of a product development, to a forensic

determination of product � aws and their corrective actions. NTS provides this level of competent

engineering coupled to a 50 year heritage of expert testing, all in one package.
