这段话不知道怎么理解,怎样做方法确认
Intermediate Precision to Pt-Co 100 level -Based on an intermediate precision standard deviation of 0.44+0.0057(Pt-Co reading), two single test results obtained from two sample of the same material in the same laboratory by the same operator and on the same instruments in a short period of time should not differ by more than 1.23+0.0161(Pt-Co reading)
y=0.0057X+0.44  Intermediate Precision SD
Y=0.0161X+1.23  Interediate Precision  at 95% confidence level
请问这个精密度确认是选用100的标液吗? 精密度一般不是测试8次数值吗?后面的在95%置信区间的精密度怎么理解,是做两次数值吗?
