ASTM D8428-21

4.1Analyst Competence is one of the largest influencing factors in whether a test method performed in a laboratory yields accurate and precise test results and thus is an important aspect in managing a laboratory.

4.2Some Regulations, International Management System Standards, such as ISO 9001, ISO 17025, AASHTO R-18, etc., and Quality Management Systems may require the establishment of analyst competence. This guide aims to provide general guidance in some of the possible approaches that may be taken to fulfill such requirements.

1.1This guide covers general guidance on assessing the competence of an analyst to perform a specific test method for a specific product or set of products (for example, light distillates). It also provides guidance on some of the possible approaches that may be taken to perform the assessment.

1.2This guide is intended for the establishment of competence for the entire performance of a test method (that is, sample preparation, instrument set up, preparation of standards and reagents, performance of the test method, calculations, etc.) or the establishment of competence may be limited to a specific aspect in the performance of a test method (for example, sample preparation).

1.3The establishment of analyst competence should only be performed if the laboratory itself is capable of performing the test in strict conformance with the test method (that is, has the equipment, standards and reagents, materials, etc. which meet test method requirements).

1.4This guide does not cover training of an analyst, other than a review of training records to indicate the analyst has been trained.

1.5This guide does not cover the establishment of general technical competence of an analyst.

1.6This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7This 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.
