Introduction
With the progress of science and technology and the development of international trade, the quality of laboratory chemical analysis methods and testing data
A higher requirement. At present, some foreign countries have released some confirmation rules about the chemical analysis methods, but our country has not released the chemical points
Analysis of laboratory methods to confirm and verify the standard or guideline in the actual laboratory testing, often encountered in the current testing standards
Unable to cope with the rapid development of detection methods. In order to provide more accurate and efficient testing services, laboratories often need to adopt
Self-developed or improved detection methods, especially in the area of chemical analysis, more and more laboratories use standards other than detection methods, but
How to ensure the suitability and reliability of these detection methods has been controversial. In addition, the laboratory according to the different needs of customers, need to choose
New standard methods, how laboratories demonstrate the technical capabilities of new standard test methods, the accuracy and reliability of test results, and
There is no uniform approach.
This standard is the laboratory chemical analysis methods to confirm the methodological and methodological guidance document to improve the laboratory chemistry
Analyze methods and quality of test data to ensure that the data provided by chemical analysis laboratories are valid, fair and reliable.
Conformity assessment methods for the confirmation and verification of chemical analysis methods
1 Scope
This standard gives the laboratory chemical analysis methods to confirm the methods and methods to verify the general principles.
This standard applies to non-standard laboratory methods, laboratory methods developed beyond its intended scope of use of standard methods to expand and
Method validation of modified standard methods, and laboratory validation of methodologies prior to the official introduction of the new standard method.

3.1
Method validation methodvalidation
Laboratory tests to provide objective and valid evidence that a particular test method to meet the intended use.
Notes 1. Method Validation It is advisable to establish the performance characteristics and limitations of the method used, identify the factors that influence the performance of the method and the extent of the effects, and determine the appropriate method
The matrix used, as well as the correctness and precision of the method.
Note 2. Adapted from ISO /IEC Guide 99.2007, Definition 2.45.
3.2
Method validation methodverification
Laboratory verification, to provide objective and valid evidence to meet the requirements of test methods.
Note. Adapted from ISO /IEC Guide 99.2007, Definition 2.44.
3.3
In-house method validation in-housemethodvalidation
In a laboratory, within a reasonable time interval, using a method under the predetermined conditions for the same or different sample analysis
Test to prove that the specific test method to meet the intended use.
3.4
Interlaboratory method validation interlaboratorymethodvalidation
Method validation between two or more laboratories. Laboratory in accordance with the predetermined conditions in the same method for the same sample determination,
To prove that the specific test method to meet the intended use.
