Failure Mode / Mechanism Distributions (FMD) 2016 BUY NOW




The data you need for FMEAs, Process FMEAs, FMECAs, and other reliability analyses is only a subscription away.

Buy an annual subscription to failure mode, mechanism and rate data for $500.


You will view the data through ROADS, which is easily searchable and accessible directly in your web browser. No installation is required.


ROADS includes Quanterion Solutions’ popular databooks:

Failure Mode / Mechanism Distributions (FMD)

Nonelectronic Parts Reliability Data (NPRD)

Electronic Parts Reliability Data (EPRD)


Quickly find component failure rates/modes and mechanism data for your analyses using a searchable interface.

How the Data Is Used

Engineers around the world use the reliability data to:

  • Perform reliability analyses including:
    • Failure Mode Effects Analysis (FMEA)
    • Failure Mode Effects and Criticality Analysis (FMECA),
    • Fault Tree Analysis (FTA),
    • And more.
  • Meet reliability requirements
  • Improve product and system reliability
  • Build reliability into new designs
  • Produce software for calculating reliability (ask about incorporating our data!)
  • And more!

How to Access the Data

It’s as easy as 1-2-3!

  1. Purchase a ROADS subscription. It costs $5000 per user for one year.
  2. Instantly receive an email with your login details.
  3. Log in and search for the data you need.

That’s it! No installation required!

And the best part about getting started with ROADS? The steps are so easy that you don’t have to involve your IT department, and Quanterion Solutions (the ROADS developer and reliability data collector) is happy to help you if you have any questions.

You can always cancel your annual subscription anytime.

The ROADS interface has been recently updated, which means you can benefit from faster search capabilities. As a ROADS subscriber, you’ll have access to automatic feature and databook updates.*


Testimonial From a Current ROADS Subscriber

“It is easy to access online from my computer even if I am working from home.The Search has drop-downs to suggest nouns for items to help determine a good description of exactly the item I may be looking for. It also works by just starting to type a word which makes it pretty quick to find the item in a search.

“The failure modes listed for an item provide us with more confidence [when] we have considered all aspects of failure within our FMECA. Dates provided on the source help us determine if the data is relevant to our similar item, same for the Environment and quality fields.”

Gail F., Current ROADS Subscriber.
