MRI용 전자파 인체 흡수율(SAR)측정 Specifi cations describe the performance of parameters covered by the product warranty and apply over 5 to 50 °C unless otherwise noted. 95th percentile values indicate the breadth of the population (？2σ) of performance tolerances expected to be met in 95 percent of the cases with a 95 percent confi dence for any ambient temperature in the range of 20 to 30 °C. In addition to the statistical observations of a sample of instruments these values include the effects of the uncertainties of external calibration references. These values are not warranted. These values are updated occasionally if a signifi cant change in the statistically observed behavior of production instruments is observed. Typical describes additional product performance information that is not covered by the product warranty. It is performance beyond specifi cations that 80 percent of the units exhibit with a 95 percent confi dence level over the temperature range 20 to 30 °C. Typical performance does not include measurement uncertainty. Nominal values indicate expected performance or describe product performance that is useful in the application of the product but is not covered by the product warranty |
