Description

ASTM D3670-91-Reapproved2022

Active Standard: Standard Guide for Determination of Precision and Bias of Methods of Committee D22

ASTM D3670

Scope

1.1 This standard provides guidance to task groups of Committee D22 on Sampling and Analysis of Atmospheres in planning and conducting collaborative testing of candidate methods.

1.2 It is intended for use with other ASTM practices for the determination of precision and bias.

1.3 It is applicable to most manual and automated methods and to most components of monitoring systems. It is recognized that the evaluation of monitoring systems may provide special problems. Practice D3249 should be considered for general guidance in this respect.

1.4 It is directly applicable to chemical methods and in principle to most physical methods, sampling methods, and calibration procedures.

1.5 The processes described are for the general validation of methods of test. A user has the obligation and responsibility to validate any method it uses for a specific application and to demonstrate its own competence in the use of validated methods.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
