Significance and Use
4.1 This practice is designed to assist suppliers and users of reference materials by identifying the information necessary on the certificate of analysis of materials designated for use in ASTM test methods. This practice is specifically designed to ensure that materials suitable for use as either calibration or quality control standards are available. This practice does not define a specific certification protocol, but rather provides guidance in the development of adequate data to support the use of the material as either a calibration or quality control standard. Suppliers are referred to ISO Guide 35 for guidelines on acceptable certification protocols. End users are referred to ISO Guide 31 for a more complete description of the elements of typical certificates of analysis.
1.1 This practice covers the information that must be provided on certificates of analysis of reference materials designated to support ASTM methods. It provides end users of these materials with a defined set of data that is required to be on a certificate of analysis and provides information to assist the end user in evaluating the independence of the material. Similarly, it provides the suppliers of reference materials with a consistent format for the presentation of certification data.
