ASTM F 3560 : 2022

1.1This specification has been developed to facilitate exchanging and analyzing particle size distribution (PSD) by light scattering data from databases, data management systems, point of origin, or other data sources that may use different data dictionaries, schemas, or formats.

1.2This specification prescribes the use of a common exchange format in such a way that PSD data defined through proprietary means can be easily exchanged for process understanding and qualification.

1.3This specification facilitates the interoperability of PSD data by identifying the data elements defined in standardized terminology, as well as defining those salient terms with indisputable meanings. In doing so, this specification extends the common AM data dictionary defined in Practice F3490 to encapsulate PSD process-specific data elements. Generic data elements and relationships present in that standard are inherited and applied in this practice where relevant.

1.4This specification specifies names that serve to uniquely identify the PSD data elements. The data type, value domain, and term definition for each data element are also specified in this practice. References are provided for those data elements with established definitions or reporting guidelines in existing standards.

1.5This specification prescribes a file format and structure for the exchange of PSD data. This format defines a method for sharing data via the defined PSD data elements herein and provides a basis for validation of data exchanged using this format.

1.6This specification recommends levels of data sharing that vary from minimal to robust. It prescribes best practices for checking conformance based on the common data exchange format.

1.7This specification does not specify:

1.8The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.9This 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.
