GB/T 22554-2010Linear calibration using reference materials (English PDF)

Foreword

This revised standard adopts ISO 11095:1996 "based on a linear calibration standard sample" (Linearcalibrationusingreference materials).

This standard and ISO 11095. The main difference compared to 1996 is as follows.

--- Deleted international standards foreword;

--- Use a range of statements in the form of typical language guide, and made the appropriate editorial changes and adjustments in some equivalent conditions;

--- Cited international standards of our standards;

--- The original International Standard Appendix A "symbol used" Adjust this standard 3.2;

--- The original International Standard Appendix B "basic methods ranging from the number of repetitions when the" Adjust this standard Appendix A.

Appendix A of this standard is a normative appendix.

Application of this standard by the National Standardization Technical Committee on statistical methods (SAC/TC21) and focal points.

Introduction

Calibration is the most core part of the measuring program, which is operating under a set of prescribed conditions for establishing measurement values \u200b\u200bare given with a these "Standards" to accept the relationship between values.

Standard sample is a substance or article of one or more properties are well established and sufficient to confirm the measurement system, existing in Several categories.

a) internal standard samples, developed by the user for internal use;

b) External standard sample, provided by an external;

c) certified reference samples, distribution and value to be recognized by the competent institutions.

Based on a linear calibration standard sample

1 Scope

This standard specifies the calibration and measurement system is calibrated measuring system maintained in statistical control state general principles.

This standard specifies the basic method used for the following purposes.

a) measuring the variability estimate assumes two kinds of linear calibration function;

b) linear calibration function and measurement variability of test assumed;

c) based on measured values \u200b\u200bof the new calibration functions transformed unknown quantity estimates.

This standard gives a method of controlling the life cycle of calibration function is used.

a) calibration function test when it needs to be updated;

b) Assessment by the uncertainty of the measured values \u200b\u200bafter calibration function transformation.

This standard specifies two alternative methods under certain conditions, the basic method, gives an example of the basic methods and control methods.

This standard applies to the measurement system can obtain the standard sample and measuring system assumes a linear calibration function, and provides a linear false test Given method.

This standard does not apply to non-linear calibration functions are known, unless the use described in 8.3 "Squeeze technology." this standard does not distinguish between the various types of standard samples, and accepts that the measuring system calibration standard sample error does not exist.
