16 Feb Siemens SN SN is a Siemens AG standard for the reliability prediction of electronic and electromechanical components. WHAT’S. MTBF calculation with Siemens SN In simple words, SN is a ready-for-use version of IEC (also published by Siemens company). Calculations for parts, components and modules are based on the following standards. IEC , SN and MIL-HDBKF. The “Parts Count” standard.

The basis for the definition of the reference conditions and the conversion models for failure rates depending on the stress conditions is the lEC I have never heard of this before.
All 12 documents have individual revisions, which makes it difficult to name a formal SN revision.
Siemens SN Standard – RMQSI Knowledge Center
It appears that the remaining Siemens Divisions no longer appear to be supporting this document or making it available. 229500 Solutions for the Railway. Any idea what this is? When more information becomes available, we will post the data.
Articles Fault Tolerance for Digital Systems. Siemens SN Electronic Reliability Prediction The latest release from ITEM Software is an extraordinary collection of new capabilities that provides a customizable, cross-platform, multi-user, open frame-work.
User name Password Remember me Log in. This standard also contains the underlying conditions for which the component failure rates apply reference conditions. With iQT, you are wn longer limited by the technology choices of software vendors or chained to infrastructure requirements of their products.
Siemens SN Electronic Reliability Prediction Software – iQT
Focused on reliability, safety, and risk assessment, our iQT product is a highly extensible framework that provides common infrastructure for any kind of system modeling. Dealing adequately soemens technical uncertainties. It appears that these links have not been replaced with new, active links. The following are examples of possible iQT extensions:.
Siemens SN29500 Standard
By allowing capabilities to be added to or removed from the software without affecting other extensions, new functionality, perhaps a new prediction standard, can be added without requiring reconfiguration or redesign of the source code. Back to desktop version Back to mobile version. Furthermore, SN has even some global recognition.
Has anyone used Siemens standard SN? PDF viewers Search tools. Please come back to me Guido: To an increasing degree, customers require demonstration of reliability calculations for the products. Reference to such conditions is needed when failure rates are stated or when values from different sources are compared.
For electromechanical components like switches, relays, contactors and connectors, Siemens SN offers the most sophisticated and therefore the best calculation models among all electronic reliability standards, while keeping the required model parameters even simple to assess. The following are examples of possible iQT extensions: The stress models described in this standard are used as a basis for conversion of the failure rate data at reference conditions to the actual operating conditions.
The well-established core services of this platform provide the essential functionality to model and analyze reliability, risk and safety projects. RAM Commander Version 8. John Reade Staff answered 10 years ago.
The latest edition of this standard is Is there anyone still interested in this?
We have also been able to confirm it with different calculations and comparison with the real world. Open and Extensible Focused on reliability, safety, and risk assessment, our iQT product is a highly extensible framework that provides common infrastructure for any kind of system modeling.
I was not able to locate any other source for the SN standard. Practical experience suggests that the SN environment type is probably avarage industrial environment. SN has been developed and is maintained and updated by Siemens company, with the latest issue Could you contact your Siemens source and place here new 2 links? By following the predefined interface, your team has the ability to create plug-ins that extend the capabilities of iQT.
New editors or viewers for a given model file type New quantification model types New result types New analysis engines The well-established core services of this platform provide the essential functionality to model and analyze reliability, risk and safety projects. All extensions are highly modular. Since it is a german standard, SN is always a good choice in germany with the exception of military and aviation industry. In general however, SN is rather a simple standard with limited component type coverage and a limited set of different categories.
I contacted our source at Siemens Medical and he has not used this product but did provide two web sites for more information. The latest release from Eiemens Software is an siemen collection of new capabilities simeens provides a customizable, cross-platform, multi-user, open frame-work.
295500 Hello there, we are using this SN — with pretty much success. Guest Forum User asked 16 years ago. Under these circumstanc the SN standard are used as a basis for conversion of the failure rate data at reference conditions to the actual operating conditions in the case that operating conditions differ significant from reference conditions.
Siemens SN 29500
Version management plug-ins Project management plug-ins Third-party computational environment tools e. The reference conditions adopted are typical for the majority of applications of components in equipment.
SN – Siemens. Regardless of the configuration of a particular installation, the core services are available in the framework. SN will be updated periodically and is available on request. Introduction to Successful Prediction of Product Performance.
