  2. Safety integrity level - Wikipedia

    en.wikipedia.org/wiki/Safety_integrity_level

    The tolerable level of these risks is specified as a safety requirement in the form of a target 'probability of a dangerous failure' in a given period of time, stated as a discrete SIL. Certification schemes, such as the CASS Scheme (Conformity Assessment of Safety-related Systems) are used to establish whether a device meets a particular SIL ...

  3. Speech interference level - Wikipedia

    en.wikipedia.org/wiki/Speech_Interference_Level

    Speech Interference Level (SIL) is an acoustical parameter calculated from sound pressure levels measured in octave bands.It is used to characterize a noise signal in the frequency range where the human ear has its highest sensitivity.

  4. IEC 61508 - Wikipedia

    en.wikipedia.org/wiki/IEC_61508

    The safety integrity level (SIL) provides a target to attain for each safety function. A risk assessment effort yields a target SIL for each safety function. For any given design the achieved SIL is evaluated by three measures: 1. Systematic Capability (SC) which is a measure of design quality. Each device in the design has an SC rating.

  5. Safety instrumented system - Wikipedia

    en.wikipedia.org/wiki/Safety_instrumented_system

    An SIS performs a safety instrumented function (SIF).The SIS is credited with a certain measure of reliability depending on its safety integrity level (SIL).The required SIL is determined from a quantitative process hazard analysis (PHA), such as a Layers of Protection Analysis (LOPA).

Xuan Kong Flying Star feng shui or Xuan Kong Fei Xing [1] is a discipline in Feng Shui, and is an integration of the principles of Yin Yang, the interactions between the five elements, the eight trigrams, the Lo Shu numbers, and the 24 Mountains, by using time ...

  7. Failure mode, effects, and criticality analysis - Wikipedia

    FMEA is a bottom-up, inductive analytical method which may be performed at either the functional or piece-part level. FMECA extends FMEA by including a criticality analysis, which is used to chart the probability of failure modes against the severity of their consequences. The result highlights failure modes with relatively high probability and ...

    ditto for units suffix. use, e.g. "Kg" so values will show as 88Kg instead of 88 in legend. underscore ("_") are replaced by spaces, to allow a space between the value and the suffix. hide group legends: Setting to true prevents displaying of the group legends under the chart. Any non-empty value means "yes".
