Analysis: Per ISO 13849-1, the Microphone System is a support and information system.

Architecture of the MR250 System ISO 13849-1 requires a reliability assessment of MTTFd which is then used in the determination of PL and SIL values.. The method used is the Parts Count method per MIL-HDBK-217 Notice 2 supplemented by updates provided by VITA 51.0/51.1. For the optical sources used in the remote unit, we used MTTF data provided by the device manufacturers. Standard component failure factors from MIL-HDBK-217 Notice 2 were supplemented by: (1) updated reliability factors provided by VITA and (2) failure rate data provided by the optical source manufacturers. These resultant MTTF failure rate is provided in the summary table. For determination of MTTFd, Annex C of ISO 13849-1 provides guidance that typically only 50% of failures lead to a dangerous failure. Therefore MTTFd is calculated to be twice the MTTF value. MTTFd is then used to determine PL and SIL classifications per Table 1 of TR-62061. These values are provided in the summary table at the beginning of this section.

APPENDIX A: Terms and Acronyms ATEX Atmosphères Explosibles (Explosive Atmosphere). By ratifying the guideline 94/9/EC

on 23 March 1994 the European Parliament and the Council of the European Union started to harmonize the different national legislative provisions for the operation in areas with potentially explosive atmospheres. As an acronym, ATEX generally refers to the equipment regulations and standards established by EU directive 94/9/EC.

Standardization), CENELEC (European Committee for Electrotechnical Standardization) and ETSI (European Telecommunications Standards Institute):

FCC Federal Communications Commission (U.S. Government) FDA Food and Drug Administration (U.S. Government) IEC International Electrotechnical Commission. IEC is the international standards

commission that prepares and publishes all standards for electrical, electronic and related technologies. The worldwide organization promotes international unification of standards or norms. Its formal decisions on technical matters express, as nearly as possible, an international consensus. www.iec.ch

Inherently Safe Visible or infrared radiation that is incapable of producing sufficient energy under

normal or Optical specified fault conditions to ignite a specific hazardous atmospheric mixture. In this Radiation document, the term “intrinsically safe” is preferentially used because the industrial

community is more familiar with this terminology and less familiar with the new terminology developed with the very recent release (August 2006) of IEC 60079-28 Edition 1.0.

Intrinsically According to IEC 60079-28, the term “intrinsically safe” now specifically applies to

electrical Safe circuits while “inherently safe” applies to optical radiation. The terms are used

interchangeably in this document due to the user’s greater familiarity with “intrinsically safe”

MTTF Mean Time To Failure. Expectation of the mean time to failure. MTTFd Mean Time To Dangerous Failure. Expectation of the mean time to dangerous failure. PL Performance Level (PL) describe the targeted level of safety performance for a

given system. Standard ISO/EN 13849-1 defines five PL levels a-e. SIL Safety Integrity Level (SIL) is a relative level of risk-reduction provided by a safety

function, or to specify a target level of risk reduction..Standard IEC 61508 defines four levels SIL 1-4.

Simple As defined in the EC ATEX Guidelines, simple apparatuses (exclusions to the

Directive) are Apparatus “equipment and protective systems where the explosion hazard results exclusively

from the presence of explosive substances or unstable chemical substances.” In other words, under intended use and fault condition, the equipment have no known effective source of ignition.
